Problems solved by technology

[0002] At present, blasting is mostly used in the construction of road rocky slopes. Generally, precise chiseling is not carried out. The slope surface is relatively rough, the overall flatness is poor, the maintenance cost is high in the later stage, and the appearance effect is not good. With the increase of road network construction projects, People have higher and higher requirements for road driving environment, road construction quality and safety of side slopes on both sides of the road, and put forward higher requirements for the construction quality and technology of slopes.

Embodiment Construction

[0022] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0023] Such as figure 1 , figure 2 As shown, the invention provides a kind of road rock slope construction method, comprises the following steps:

[0024] Step 1: Use an excavator to excavate the rock and soil, and reserve an appropriate amount of cutting allowance to obtain a slope 1 on both sides of the road; Layer by layer excavation, when excavating each layer of rock and soil, it is excavated segment by segment in the order from the inside of the road to the outside of the road. Layer-by-layer progressive excavation refers to the use of excavators to excavate multiple times, and each layer of rock and soil is excavated. After each layer of rock and soil is excavated, the thickness of the excavated rock and soil is retested to make each layer of rock and soil The thickness is less than 2000mm. Sectional progressive excavat...

Abstract

The invention provides a construction method of a road rock side slope. The construction method comprises the steps that rock and soil are excavated by an excavator, an appropriate amount of chiselingmargin is preserved, and first-time slopes are obtained on both sides of a road; a crusher is used for chiseling the first-time slopes in a top-down order, a part of the chiseling margin in the firststep is chiseled, that is, margin coarse chiseling is performed, and second-time slopes are obtained on both sides of the road; and the crusher is used for chiseling the second-time slopes in a top-down order, the remaining part of the chiseling margin in the first step is chiseled, that is, margin fine chiseling is performed, and formed slopes are obtained on both sides of the road. According tothe technical scheme, the construction method is mainly applicable to the construction operation of a road side slope without the need of the support, so that the slope surface of the rock side slopeformed after the construction is smoother, the appearance is more attractive, the construction operation difficulty is reduced, the investment in construction materials and manpower of enterprises isreduced, the construction quality and construction efficiency of the road side slope are improved, and a foundation for the subsequent construction process is laid.

Description

technical field [0001] The invention relates to the technical field of road construction engineering, in particular to a road rock slope construction method. Background technique [0002] At present, blasting is mostly used in the construction of road rocky slopes. Generally, precise chiseling is not carried out. The slope surface is relatively rough, the overall flatness is poor, the maintenance cost is high in the later stage, and the appearance effect is not good. With the increase of road network construction projects, People have higher and higher requirements for road driving environment, road construction quality and safety of side slopes on both sides of the road, and put forward higher requirements for the construction quality and technology of slopes. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a road rock slope construction method. [0004] The present invention is achieved through the follow...
