Problems solved by technology

However, prefabricated concrete slabs have problems such as heavy weight, high cost, inconvenient transportation and installation, broken slabs, and many corner-dropping diseases.
The laying of steel plates has problems such as high cost, large resource occupation, easy deformation of steel plates, and poor driving comfort.
[0003] In recent years, in order to solve these technical problems, some cities and construction units have begun to study prefabricated temporary roads, but the existing prefabricated roads still have the problems of high cost and complicated installation procedures

Embodiment 1

[0025] Such as Figure 1-3 Shown, according to the construction method that is used for fast road construction of preferred embodiment of the present invention, comprises the following steps:

[0026] Step 101: Excavating, filling and leveling the site: Excavating, filling and leveling the site by manual or mechanical means according to the elevation required by the design.

[0027] Step 102: Use a road roller or a dynamic compaction machine to tamp the subgrade 8, and keep the top surface of the subgrade 8 at a slope of 2%-4%, so that rainwater can be smoothly discharged from the road surface.

[0028] Step 103: Fabricate a waterproof geotextile 1, wherein the top and bottom surfaces of the waterproof geotextile 1 are made of wear-resistant and anti-damage materials, and the middle layer is made of plastic waterproof cloth.

[0029] Step 104: laying waterproof geotextile 1 on the top surface of the compacted roadbed 8: Excavating grooves 7 on both sides of the roadbed 8, spr...

Embodiment 2

[0042] According to the construction method for road fast construction of preferred embodiment of the present invention, comprises the following steps:

[0043]Proceed to step 101. Preferably, a bulldozer is used to level the site, and then a smooth road roller is used to reciprocate and roll over three times until the vehicle passes through the concave wheel base. For clay, sandstone, expansive soil, loess, saline soil, and frozen ground, it can be directly leveled and rolled. For the soft soil subgrade, first excavate the soft soil part 60 cm below the ground, and replace it with non-soft soil materials, such as clay, sand, loess, saline soil, frozen soil and other materials. For the silt subgrade, all the silt can be excavated and replaced with other soil, or the ground can be leveled after laying rubble in the silt.

[0044] Proceed to step 102, and use a smooth road roller to tamp the roadbed 8.

[0045] Proceed to step 103, fabricate the waterproof geotextile 1 in the ...

Embodiment 3

[0054] According to the construction method for road fast construction of preferred embodiment of the present invention, comprises the following steps:

[0055] Proceed to step 101, use a bulldozer to level the site, and then use a smooth road roller to reciprocate for more than three times, and roll the roadbed until the vehicle passes through the base stamp without the concave wheel.

[0056] Proceed to step 102, and use a smooth road roller to tamp the roadbed 8.

[0057] Proceed to step 103, manufacture the waterproof geotextile 1 in the factory, the top surface and the bottom surface of the waterproof geotextile 1 are made of polyethylene woven cloth, the middle interlayer is made of plastic waterproof cloth, and the thickness of the plastic waterproof cloth is selected as 0.03mm.

[0058] Carry out step 104, excavate groove 7 on both sides of subgrade 8, the width of groove 7 is 0.3m, the depth of groove 7 is 0.3m, and the layered thickness of backfilling natural plain s...

Abstract

The invention discloses a construction method for quickly building a road. The construction method comprises the following step that a site is dug, filled and leveled; the roadbed is tamped; waterproof geotextile is manufactured; grooves are dug in the two sides of the roadbed, the top face of the compacted roadbed is flatly laid with the waterproof geotextile, the ends of the waterproof geotextile extend into the grooves, then the grooves are backfilled with natural plain soil layer by layer, and compaction is conducted layer by layer; road slabs are manufactured, and a plurality of anchoringholes are formed in the middles and the edges of the road slabs; the road slabs are installed, specifically, the multiple road slabs are spliced and flatly laid on waterproof geotextile one by one, anti-skid lines of the road slabs face upwards, and slab joints of the multiple road slabs and hole positions of the anchoring holes are aligned; reinforcing parts are manufactured, wherein the reinforcing parts are U-shaped hoops and L-shaped hoops; the U-shaped hoops and the L-shaped hoops are used for reinforcing the road surface; secondary waterproof treatment is carried out; and the traffic isput into service.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a construction method for rapid road construction. Background technique [0002] Most of the current low-grade roads are cement concrete pavement or asphalt concrete pavement, and the cost of road construction is high and the construction period is long. Other gravel roads or mud-bound gravel roads have poor driving comfort, heavy dust, and low traffic efficiency in rainy days. In addition, when the road needs to be demolished, a large amount of construction waste will be generated, causing environmental pollution. Especially for some temporary roads, the commonly used methods are prefabricated concrete slabs or laying steel plates. However, prefabricated concrete slabs have problems such as heavy weight, high cost, inconvenient transportation and installation, broken slabs, and many corner-dropping diseases. The laying of steel plates has problems such as high cost,...
