Assembled road structure and construction method

Abstract

The present invention belongs to the field of prefabricated temporary roads, and discloses a prefabricated road structure and construction method. It is characterized in that an anti-misalignment net is laid in the foundation soil layer and the gravel layer, and is arranged in a wavy shape. The crests and troughs of the two are fixed by steel wire binding to improve the structural durability of the foundation soil layer and the gravel layer, and to avoid the occurrence of misalignment and loss of stability. Secondly, the road monomer adopts a layered structure with a permeable surface and a non-permeable bottom. The permeable part is used to quickly drain water, and the water is led out through the water diversion belt inside the pre-buried seepage pipe base to avoid water seepage and instability in the roadbed. The water diversion belt uses the gravity and rapid evaporation of the leaking end to lead the internal water out. A sealing body is also provided between the non-permeable parts of two adjacent road monomers to solve the problem of water seepage in the joints. The problem of leakage can be further solved by adding a waterproof membrane at the bottom of the road monomer.

Description

Technical Field

[0001] The present invention relates to the field of assembled temporary roads, and in particular to an assembled road structure and a construction method. Background Art

[0002] On construction sites such as housing construction, subway construction, underground pipeline laying, and underground sidewalk construction, temporary roads are usually needed to transport earth out of the site and various building materials such as steel bars, concrete, bricks, and formwork into the site. If excavated soil is used directly for paving, the resulting temporary roads will easily become muddy. If concrete is poured for construction, not only will the roadbed be damaged, but a large amount of construction waste will also be generated during later demolition. Therefore, the existing use of prefabricated roads as temporary roads, which have a smooth surface and do not generate construction waste, can meet the needs of most construction sites.

[0003] At present, prefabricated roads usually include multiple road slabs. The road slabs are usually made of concrete and need to be made in advance. During construction, the roadbed needs to be flattened first, and then the road slabs are laid on the roadbed and assembled on site. Since the road slabs are prepared in advance, the construction is more convenient, which greatly saves construction time.

[0004] A search revealed that existing prefabricated road structures are generally assembled using mortise and tenon joints, such as those in CN118207766A. While this structure improves integrity, it cannot be quickly and effectively replaced if a road block is damaged. Furthermore, the subgrade of existing prefabricated roads has poor resistance to horizontal slippage, especially in curved areas. Vehicles traveling around curves can easily cause the subgrade to slip, potentially damaging the prefabricated road structure. Summary of the Invention

[0018] Step 1: Foundation soil construction

[0019] The foundation soil layer is constructed on the ground foundation. Rods are embedded in the foundation soil layer. The bottom of the rods is anchored in the ground foundation and compacted to the design elevation. Then, lines are drawn on the foundation soil layer to mark the position of the anti-staggered net and the drainage ditch required by the design.

[0020] Excavate the drainage ditch area according to the marked drainage ditch position, lay a concrete base support in the drainage ditch, and set an anchor structure arranged obliquely downward at the bottom of the concrete base support located on the outside to increase the lateral displacement resistance through the anchor structure;

[0022] Step 2: Gravel layer construction

[0023] A crushed stone layer is laid on the foundation soil layer, and rods with the same structure as those in the foundation soil layer are pre-buried in the crushed stone layer. The rods in the foundation soil layer and the crushed stone layer are connected by male and female connectors and leveled to half of the design elevation.
