[0002] Construction access roads refer to temporary access roads erected during construction. After the construction is completed, the construction access roads need to be removed. Construction access roads are generally paved with brick slag, etc., which have poor water resistance and water conductivity. They become loose when exposed to water, which can easily lead to serious deformation of the road surface. In order to solve the problem of serious deformation of the road surface caused by the looseness of construction access roads when exposed to water, the following measures are often adopted: 1. Use crushed stone in the roadbed to increase the drainage performance of the roadbed and facilitate the flow of accumulated water in the roadbed, but the road surface bearing capacity of this roadbed is insufficient, the drainage efficiency is low, and it cannot be recycled; 2. Replace the roadbed. This solution has low construction efficiency, is time-consuming and labor-intensive, and increases costs. Utility Model Content

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] The drainage type recyclable combined construction access road of Example 1 is as follows Figure 1 to Figure 3 As shown, it includes a roadbed 1, a drainage steel pipe 2 and a steel plate surface layer 3. The roadbed 1 is paved with medium-sized gravel. There are a plurality of drainage steel pipes 2, which are vertically inserted into the roadbed 1. The diameter of each drainage steel pipe 2 is 800 mm. The bottom end of each drainage steel pipe 2 is inserted below the ground on the lower side of the roadbed 1. The upper end surface of each drainage steel pipe 2 is flush with the road surface of the roadbed 1. A plurality of first drainage holes 21 are opened on the side wall of each drainage steel pipe 2. The steel plate surface layer 3 covers the road surface of the roadbed 1, and a plurality of second drainage holes 31 are opened on the steel plate surface layer 3.

[0020] The drainage type recyclable combined construction access road of Example 2 is different from that of Example 1 in that, in Example 2, Figure 4 As shown, the top of each drainage steel pipe 2 is detachably covered with a steel cap 4, the upper end surface of each steel cap 4 is flush with the road surface of the roadbed 1, and a plurality of third drainage holes 41 are opened on each steel cap 4. Each steel cap 4 has an annular brim 42, and the annular brim 42 of each steel cap 4 is sleeved on the outer side of the top of a drainage steel pipe 2.

[0021] Taking the drainage type recyclable combined construction access road of Example 2 as an example, the paving process is as follows:

[0022] (1) Remove the soil from the ground to the designed access road base elevation;

[0023] (2) A plurality of drainage steel pipes 2 are driven vertically into the ground so that the top elevation of each drainage steel pipe 2 is flush with the designed top of the access road;

[0024] (3) Cover the top of each drainage steel pipe 2 with a steel cap 4;

[0025] (4) laying medium-sized gravel on the outside of the drainage steel pipe 2 and filling it to the designed top elevation of the access road to form a roadbed 1;

[0026] (5) Lay the steel plate surface layer 3 on the top of the roadbed 1.

[0027] After the construction access road is laid, the roadbed 1 paved with medium-sized gravel has good water resistance and water conductivity, and water can freely pass through the gravel pores and flow into the drainage steel pipe 2 through the first drainage hole 21 on the side wall of the drainage steel pipe 2. When drainage is required after a heavy rain, the drainage steel pipe 2 is removed, and a vacuum pump is placed in the drainage steel pipe 2. The water in the drainage steel pipe 2 is pumped out by the drainage pump, and the drainage efficiency is high. The negative pressure formed during the drainage process is also conducive to the rapid collection of water in the roadbed 1 into the drainage steel pipe 2, thereby further improving the drainage efficiency. After the construction is completed, the access road can be dismantled, and the drainage steel pipe 2, the steel plate surface layer 3, the medium-sized gravel and the steel cap 4 can be recycled and reused.
