Desert, Beach & Sandy-Site Projects

There is no stable adhesion in the sand, and the acceleration, rapid rotation or brake of the vehicle will push the grain towards the edge of the plate and the seams, causing a gradual emptiness or rise under the plate.Even when first laid flat, successive car runs can then form wave-like ground, leading to the rise of the plate.The project should select a smoother route, remove loose sand piles from the surface and moderately level them, and lay them from stable hard to sand;(c) Limit speed and rapid turn and set fixed wheel tracks.The inspectors were required to clear the panels, check the edges and remove the stitches, and when the holes were found, lift the plates back to level, rather than keep the vehicles running over.In response to the “continuing migration of loose sand under wheel drive and brake”, the Desert, Beach and Sand Project should also include the results of the inspection in the pre-class confirmation and handover records, identifying who is responsible for release, who is responsible for inspection, what deposition or relocation must be discontinued.Retroactive recording of photographs, measurements and usages will make it possible to distinguish ground-based changes, operational deviations from product damage and avoid repetition of the same problem between different groups.

The desert has a high temperature difference between day and night, and the plate is subject to heat swelling and cold contraction;Coastal salt fog, tides and fine sands enter the connecting area, affecting the dismantling.High noon temperatures also change the handling and surface touch, and the boundary of the route is unclear when visibility decreases at night.The project should set aside space for reasonable stretching, select durable materials and regularly check connections, and clean up the beaches in a timely manner.The construction time avoided extreme temperatures and rising tides and the plate was marked with wind and sand tolerance.Environmental adaptation of connectors, metal attachments and cleaning tools should not be overlooked because of material resistance to corrosion.The handling of “high temperature, high ultraviolet, salt fog and tidal impact materials and maintenance” cannot be limited to one successful pass, but also covers the maximum load, maximum frequency, worst weather and evacuation phases.It is recommended that representative positions be selected for trial, that ground, vehicle or equipment data be recorded and that the scope, connection and frequency of maintenance be adjusted to the results;The change in conditions was confirmed and early experience was not directly applied to the entire desert, beach and sand project.

The expansion of the area on sand — Outrigger Pads — can reduce average pressure, but if the lower sand layer is loose, damp or close to the edge of the brush, the entire mat may still be tilted down.The return of cranes and wind loads also alter the reaction of legs, and changes in beach tides may weaken the grass-roots level during operations.Ground-based confirmation should be conducted prior to the operation, avoiding sand dunes slopes, swiping trenches and tidal impact areas, and levelling and crushing stations;Select the area of the padding based on the maximum one-leg reaction.Levels and depositions are monitored and reviewed after changes in wind speed, tide or payload, and it is found that the sinking of one side is stopped immediately, rather than continuing to be prolonged.The desert, beach and sand project site should set clear standards for the cessation of use, such as the continued rise of the plate end, incomplete support, extended deposition, visible slippage of the vehicle or loose-linking of the link.Unusual isolation and unloading were detected, and then the floors were repaired or reconfigured, and temporary pads were prohibited in carrying conditions.The head of the mission may not resume operations until he or she has been qualified to do so, and records of disposal are maintained.
