Embodiment 1

[0075] Embodiment 1: build a kind of as Figure 7 The specific construction method of the salt rock road in factories and mines shown is as follows: the original ground 3 is rolled and leveled, and the compaction coefficient of the original ground 3 is ≥ 92%; multi-layer salt rock is laid on the original ground 3, and each layer of salt rock is The thickness of loose laying is ≤50cm, and then rolling is carried out, and the compaction coefficient of the salt rock subgrade is ≥93%. After the salt rock rolling of each layer is completed, saturated brine is sprinkled for consolidation, and saturated brine is sprinkled at least 3 times until rolling The thickness reaches 80-100 cm to form the salt rock subgrade 1; loosely lay salt rock with a thickness of 30-50 cm on the top of the salt rock subgrade 1, and carry out rolling, and the rolling compaction coefficient is ≥ 93%, and then shaping and shaping After completion, sprinkle saturated brine for maintenance, sprinkle saturated ...

Abstract

The invention provides a factory and mine salt rock road and a construction method thereof. The construction method comprises the steps that S1, the original ground is rolled and leveled; S2, salt rock is paved on the original ground and rolled to form a salt rock subgrade; and S3, the salt rock is laid on the top of the salt rock subgrade and ground to form a salt rock pavement. According to thetechnical scheme, the salt rock is used for constructing the road, local materials are used, and road construction and raw material investment and cost are reduced; the built salt rock road is stablein performance, not prone to collapse, good in safety and easy to maintain; the constructed salt rock road meets the construction standard, the application effect is good, and the actual transportation requirement is met.

Description

technical field [0001] The present invention generally relates to the field of road construction, and more specifically, relates to a construction technology of salt rock roads in factories and mines. Background technique [0002] The soil in the Chaerhan Salt Lake area in the Qaidam Basin is chlorine saline soil. In order to ensure the transportation of materials, minerals and other resources in the mining area in this area, it is necessary to build reliable and safe factory and mine roads. The mining area of ​​Qinghai Salt Lake Industry Co., Ltd. is located in this area, with an area of ​​5,856 square kilometers. The mining area is large and there are many mining (brine mining) points in the mining area. It is too expensive to build gravel roads or asphalt concrete roads on such a large area. high. Moreover, the roadbed in Chaerhan is made of chlorine-salted soil. The roadbed is unstable after the asphalt concrete pavement is built on the chlorine-salted soil. Once it enc...
