Temporary shortcut on sludge terrain and construction device and construction method thereof

Abstract

The invention discloses a temporary shortcut on a sludge terrain and a construction device and a construction method thereof. The construction device is consisted of a vacuum extrusion pile forming pipe, a central compaction pipe, a peripheral compaction pipe, a vacuum downcast pipe and a vacuum compaction pipe, the construction device constructs a temporary shortcut on a sludge terrain with a low permeability coefficient, and rapid and low-cost shortcut construction is realized. The temporary shortcut takes a retention wall and a bearing base layer which are formed after sludge is compacted, drained and consolidated as a supporting foundation of the shortcut, local materials are used, the dependence of shortcut construction on external materials is reduced, and the construction cost is effectively reduced; the construction device is adopted to compact and consolidate the sludge, the retention wall and the bearing base layer which meet the requirements are rapidly formed, the construction difficulty is effectively reduced, and the shortcut construction speed can be effectively increased; according to the construction method, rapid construction of the shortcut construction can be achieved, construction of the shortcut is completed in a short time, and the short-term passing requirement of construction vehicles is met.

Description

technical field [0001] The invention relates to the technical field of silt soft body reinforcement construction, in particular to a temporary access road on silt terrain, a construction device and a construction method thereof. Background technique [0002] When construction is carried out in tropical areas or areas with developed water systems, in order to carry out construction, it is often necessary to build construction access roads on ponds. Generally, the construction methods of filling soil, silting, turning and drying are used for construction of access roads. However, the above-mentioned rock filling and soil filling require a large amount of construction materials, and the construction cost is relatively high. In addition, the area with developed water system is not convenient for large machinery to enter, and the transportation and construction of filling materials are more troublesome, which greatly increases the construction cost. The entire construction proces...

Problems solved by technology

However, the above-mentioned rock filling and soil filling require a large amount of construction materials, and the construction cost is relatively high. In addition, it is not convenient for large-scale machinery to enter in areas with developed water systems. The transportation and construction of filling materials are more troublesome, which greatly increases the construction cost.

The whole construction process of drying and other methods is cumbersome, the construction period is long, and it depends heavily on the season, the uncertain factors are too high, and the applicability is poor
