xrosswater has designed and built a floating walkway structure that is more versatile, stronger and durable than any other available

 

Xrosswater walkways are multi-configurable, and they can be used as floating walkways, floating docks, floating platforms, floating pontoons, and more for various applications. They are immensely strong, lightweight, and very durable. Our standard floating walkways are produced with aluminum frames, stainless steel fittings composite handrails and HMV plastic floats that have been tested to 40F and + 120F. The frames for high-acid environments are Fiber-Reinforced Plastic and stainless steel. All aluminium walkway systems have lightweight strong laminated decking with approved non-slip surface.
 
 
 

Dimensions

Once assembled, each section of the Xrosswater floating walkway is 3m x 1.5m but can be joined SIDE TO SIDE, END TO SIDE, OR END TO END. The Xrosswater walkway maintains buoyancy of up to 900kg per section.

Walkway Deck and Grating Insert

 
The Xrosswater deck surface is thick laminated covered in a matte gray overlay with a slip-resistance surface (Taber Test EN 438-2) and non-static. The deck material is also used on LPG ship decks, scaffolding walkways, and horse trucks.

Xrosswater decking is resistant to weather and common chemicals. The surface of the Xrosswater floating walkway system is either grating or a laminated panel with rough wire mesh pattern imprinted through a hot-press process to achieve the non slip.surface

A 1m long x 1.5m wide grating in safety yellow can be fitted between sections. These grating inserts reduce the linear meter price, reduces crosswind drag, and increases the flow of tailing whilst reducing channeling. The gritted or concave surface of Xrosswater grating provides a slip-resistant footing for wet or frozen environments and oily conditions.

Additional buoyancy chambers for heavy working conditions

When anchor chains are being adjusted, the fitters may accidentally drop the chain into the tailings. The second stop is a preventative measure to ensure that the chain is always connected.
 

Rubber Elastic Tensioner

Where dam water level fluctuates, the integration of elastic tensioners ensures that the walkway anchors or guy-ropes are always under tension. This eliminates the need for anchor chains to be manually tightened or slackened.

Xrosswater Anchor Load Indicators

 
This feature of the Xrosswater floating walkway is a visual indicator that the anchor chains or cable are enduring. When the load on the anchor chains has exceeded a set level, the indicator detaches, notifying that adjustments are required. Anchor load indicators have the benefit of keeping records of anchor adjustments. With this data, operators can pinpoint unsecured anchors.

Xrosswater Grating Material

 
The concave meniscus surface on the top of Xrosswater grating provides superior slip resistant footing in most environment including wet or oily conditions.

 

Xrosswater Deck Non-Slip Data

 
Xrosswater deck material meets the anti-slip class in accordance with DIN 51130-R11. The CoF is at the mid to high end of 0.40's and thus borders onto the R12 classification.

German Ramp Test: R Numbers
R-Numbers DIN 51130
The following table show the level of slip risk associate with different R-Numbers as defined by the German Ramp Test and DIN 51330. If a floor is likely to be wet then R13 is the best. Only R12 or R13 should be considered for swimming pool surrounds or changing areas. R11 may be suitable for transitional areas of floor i.e. floors that can become wet despite efforts to keep it dry such as the entrance to a shopping mall or dry changing room floor. R10 may be suitable for areas of floor that can normally be kept dry and R9, the lowest value should only be considered for floors that can never become wet or have very few people using them.
 

Deck Anchor Management Techniques

The following information is provided as an aid in determining proper anchors and installation methods. However, all sites are different. Use the proper site and soil/tailings assessment to determine the anchoring technique to use.

 

Anchor guidelines

 
The anchors used with the Xrosswater floating walkway system are critical components to the Xrosswater installation. When managed correctly, they will ensure long lasting problem free use of the floating walkway.

1) Soil Type The following information is provided as an aid in determing the proper anchors and installation methods. However, all sites are different and correct site assessment and soil / tailings determinations is required to determine what type and what quantity of anchors are required.

2) Settling Density Most Tailings deposit settle differently. It is important to determine what is the normal percentage of water to tailings that is deposited, at what rate the tailings deposit settles, and if the settled tailing has any compounding characteristics that would support and increase the holding load of the anchor. This information is significant depending upon the required load the anchors will be required to sustain and the desired lifespan of the platform or walkway.

3) Depth of Tailings With the soil type and anchor type selected, determination of what is the appropriate depth below the surface at which an anchor can obtain a respectable hold is required. This information can be obtained through proof testing at numerous locations along the proposed walkway position.

4) Weather conditions In addition to the soil type and depth, it is also important to know the weather conditions at the site, such as maximum winds, directions and icing that may collect on the water. Soil conditions can soften or change markedly with heavy rains. Since there can be variations in the precise soil condition at a site, you may want to purchase two or more types of anchor sizes for the installation of the floating walkway, and choose the appropriate anchor once you have begun installation.

5) PH Levels Understanding the present or the future PH level of the water is required to ensure that the correct chain type and linkage pieces are selected. Should there be a long distant between the anchor and the walkway, in certain circumstances, wire rope can be utilized and even at times certain fiber ropes can suffice.
 

Types of anchors

 
 
6) Chain Web Anchors
Chain web anchors is a configuration of chains that are linked together to offer a web network that is reliant upon shared anchoring points to maintain the walkway’s position. Often used in locations with tidal movements and / or where anchoring can be difficult due to steep underwater slopes, or in water reservoirs where water level can drop and increase considerably. Such anchoring configurations can require multiple types of anchor load points and ballast not normally required on Tailings Dam

7) Screw-In Anchors
Screw-in anchors are recommended for softer soil types, Classes 5-7. They do not work well in rocky soils. The screw-in anchor is a hot-dip galvanized steel bar with an eye on one end for attaching the guy wires or chain and a variable diameter screw at the bottom depending upon the soil conditions. These are standard anchors used in the utility industry.

Screw-in anchors are usually installed by two people rotating a log bar threaded through the eye, but may also be installed with a power drive machine. The large diameter anchor may be difficult to install, so it may be more practical to install two medium size anchors at certain soil type locations.

8) Drive-In Anchors
Drive-in anchors are recommended for denser, rocky soils, Classes 2-5 in Table 1. A drive-rod is used to drive the anchor into the ground. Drive rods can be driven manually with a sledge or with power equipment if available. The drive-in anchor must be “set” by pulling the anchor until it rotates 90°. We recommend proof testing each anchor with a dynamometer to ensure that it is properly installed. These anchors are useful in denser soils because they can be forced into the soil more easily, and the triangle design tends to thread around rocks in the soil.

 
rock-anchors
 
9) Rock Anchors
Rock anchors are standard in the construction industry for rocky areas. They are appropriate for soil Classes 0-1 in Table 1. They require drilling a hole for insertion of a threaded rock anchor. The anchor can then be cemented into place if desired. Grouting is necessary with soft, crumbling rocks or if weathering is expected.

The anchor is then dropped into the hole, and the eye is threaded with a bar and rotated until the anchor has expanded firmly against the sides of the hole. The anchor should be installed at a specific depth into solid rock.
 
 
10) Concrete Block
As a general rule, unless the details of the dam bed, water depth, PH level, tailings depth and density are known and appropriate design and preparations are made, concrete blocks / round barrels as individual anchors are not supported by Xrosswater Ltd. Past events at locations where other floating structure have been installed and in which concrete blocks were used as the sole anchoring solution, incurred problems such as the blocks sliding on hard rock surfaces, rolling, corrosion of eye loops, installation difficulties, blocks not heavy enough, cost of production, cost of handling, blocks moving towards penstock, etc.

Xrosswater Ltd may select the use of concrete block in certain design conditions where guidance, ballast, or a web of chains and weights are required.

11) Lined Dams & Walkway Stability
More mines are required to line the dams to prevent water leakage. In this circumstance, it is required that the anchors of the floating walkway for the tailings dam are installed before the dam in lined, so that the lining can be sealed around the anchor shaft. Second sheets of lining can be installed to prevent wear where necessary. On existing lined dams, depending upon the topographic design of the dam, water level etc., cables can be anchored to the top rim of the dam and with the use of ballast weights and floatation balls, the cables can be kept under tension, ensuring the Xrosswater Walkway will remain in position as desired. Further ballast and drogues can be inserted or attached to the floating walkways and anchor cables to increase walkway stability.
