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 house construction, subway construction, underground pipeline laying, and underground sidewalk construction, temporary roads usually need to be laid on site because of the need to transport earth out of the site and to transport various building materials such as steel bars, concrete, bricks, and formwork into the site. If the excavated soil is used directly for paving, the constructed temporary road is prone to muddy, and if concrete is poured for construction, it will not only damage the roadbed, but also generate a large amount of construction waste when it is demolished later. Therefore, the existing use of prefabricated roads as temporary roads, the prefabricated roads have a flat surface, and will not generate construction waste. The road can meet the use 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 and greatly saves construction time.

[0004] According to the search, the existing prefabricated road structures are generally assembled together through mortise and tenon structures, such as CN118207766A. Although the use of mortise and tenon structures can improve the integrity, it is difficult to effectively and quickly replace a road block when it is damaged. Secondly, the roadbed of the existing prefabricated road has poor resistance to horizontal slippage, especially in the curved area. Since vehicles driving on the curves can easily cause the roadbed to slip sideways, it is easy to cause damage to the prefabricated road structure. Summary of the invention

[0005] The technical problems to be solved by the present invention are:

[0006] The existing fabricated temporary roads have poor anti-skid ability and durability.

[0018] Step 1: Foundation soil construction

[0019] The foundation soil layer is constructed on the ground foundation. The rod body is pre-buried in the foundation soil layer. The bottom of the rod body is anchored in the ground foundation and compacted and leveled 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 according to the marked drainage ditch position to obtain the drainage ditch area, lay a concrete base support body in the drainage ditch, and set an anchor structure obliquely downward at the bottom of the concrete base support body located on the outside to increase the lateral displacement resistance through the anchor structure;

[0022] Step 2: Construction of gravel layer

[0023] A crushed stone layer is laid on the foundation soil layer, and a rod with the same structure as the rod in the foundation soil layer is pre-buried in the crushed stone layer. The rod in the foundation soil layer and the rod in the crushed stone layer are connected by a male connector and a female connector, and are leveled to half of the design elevation. A line is drawn on the crushed stone layer to mark the position where the second anti-staggered layer net is required to be laid;

[0024] Excavate at the marked position of the second anti-staggered layer net, expose the rods in the gravel layer, and pave the second anti-staggered layer net.

[0026] A leveling layer is laid on the crushed stone layer and flattened, and a waterproof membrane is laid on top after flattening, with both ends of the waterproof membrane extending into the drainage ditch and fixed by a fixing structure in the drainage ditch;

[0027] Step 4: Road construction

[0028] Insert the water diversion belt into the pre-buried seepage pipe, and expand the water diversion belt in the pre-buried seepage pipe by pulling the wire. The pre-buried seepage pipe is equipped with a thorn-proof device to prevent the water diversion belt from loosening.

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 foundation to avoid partial water seepage and instability of the roadbed. The water diversion of the water diversion belt uses the gravity of the leaking end and rapid evaporation to lead the internal water out. A sealing body is also arranged between the non-permeable parts of two adjacent road monomers to solve the problem of water seepage in the joints. The leakage problem can be further solved by adding a waterproof membrane at the bottom of the road monomer. BRIEF DESCRIPTION OF THE DRAWINGS
