Embodiment Construction

[0048] The present invention is described in detail below in conjunction with accompanying drawing:

[0049] The invention provides a construction method for a washboard road in a test field. The road surface structure of the washboard road is cement concrete, and the road surface is a washboard shape. The washboard road can be a washboard road with a width of 3.5m and a length of 100m; the construction method comprises the following steps:

[0050] Step 1, according to the construction design drawings, use the total station to accurately stake out the left and right lines of the road surface;

[0051]Step 2, set the left formwork of the concrete base along the left line, and set the right formwork of the concrete base along the right line; wherein, the formwork materials of the left formwork of the concrete base and the right formwork of the concrete base are channel steel, and are fixed with T-shaped diagonal braces to ensure concrete pouring There is no displacement of the ...

Abstract

The invention provides a construction method for a washboard road of a test field. The construction method mainly includes the steps that first-layer reinforcing meshes and second-layer reinforcing meshes are sequentially and fixedly arranged between a left concrete base layer formwork and a right concrete base layer formwork and above non-woven fabric; then multiple longitudinally-arranged force transmission rods are horizontally arranged in each transverse joint position and in an interval between each first-layer reinforcing mesh and the corresponding second-layer reinforcing mesh at equal intervals, and then concrete is poured; and steel angles are arranged on the concrete and then the concrete is poured. The method has the beneficial effects that by the adoption of the construction method, the high-strength washboard road can be obtained, and the washboard road has the beneficial effects of being high in durability, long in service life, not likely to deform and the like, so that the problem that steps of a washboard road of a test field are likely to be broken in the vehicle test process is solved, the road surface quality is effectively guaranteed, and the requirement for vehicle test detection is met.

Description

technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a construction method for a washboard road in a test track. Background technique [0002] The washboard road is mainly used for reliability and durability tests on vehicles. The construction method of the traditional washboard road is: prefabricating the cement concrete road slab according to the design requirements of the washboard road, and then installing the cement concrete road slab on the road surface. Because this kind of construction method is prefabricated and installed, it is prone to damage to the road steps during the vehicle test process. Therefore, it has the disadvantages of poor road durability, short service life and easy deformation, which cannot achieve the purpose of testing the performance of the test vehicle. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a construction metho...
