Technical Field

The invention relates to a lateral reinforcing device for a section easy to collapse and a reinforcing construction method.

Background

In the area with large partial precipitation, the mountain road of the mountain road section is easy to collapse due to the erosion of rainwater, and the reason is that the rock layer serving as the roadbed below the road surface is loose, rolling of vehicles is borne, and the support fails in cooperation with the erosion of rainwater, so that the local collapse of the road surface is caused, and great potential safety hazard exists.

The existing reinforcement method mainly includes the steps that a steel wire mesh is built on the outer side of a roadbed, water and soil loss is reduced through the steel wire mesh, and then the probability of road surface collapse is reduced.

Based on the problems, the lateral reinforcing device and the reinforcing construction method for the road section which is easy to collapse are designed for reinforcing the road section which faces the cliff and is soft in geology, so that the supporting strength of the road surface is increased, and the collapse probability is reduced.

2) assemble between railing and two adjacent baffles, during the assembly, the baffle is located the notch, and the mountain road is that the slope is laid, consequently when the installation, railing's position can be according to the height adjustment of installing the angle of baffle, and during the adjustment, the notch provides the space of adjusting, and railing can carry out the angular rotation along the baffle with the help of the notch, and rotatory when railing and pavement layer are parallel, locks through the screw promptly, and locking back railing is fixed the completion promptly.

When the pole in the installation, because the aperture of the cross bore of establishing is greater than interior pole, consequently when the pole in the location, need to insert some steel poles of support in the cross bore, the steel pole is the level setting, and the middle part position department of steel pole forms the arc part that the pole was used in the support after bending, and the both ends of steel pole are inserted in the pore wall of cross bore, and interior pole is fixed a position in the arc part, and when concreting the post, the steel pole was pour in the concrete column.

This product is laying the completion back, through the concrete column, becomes to consolidate below the roadbed, increases the anti vertical deformability of roadbed, through the cooperation of first concrete column and concrete column, forms vertical spacing, increases the structural stability that the concrete column closes on that one end of massif.

This product need not solitary assembly guardrail again after the construction is accomplished, protects the outside protection that realizes the mountain road through the guardrail bar cooperation baffle of installing, plays the effect of anticollision, reduces the probability that the vehicle rushed out the road surface, reduces the injures and deaths.

The invention has the beneficial effects that: the invention mainly aims at reinforcing the vulnerable road section of the mountain road, in particular to the road section near the cliff, after the reinforcement of the invention, the compression resistance of the road surface is increased, the local collapse probability of the road surface can be reduced, and meanwhile, the guard rail in the product can form the outer side protection of the mountain road, the vehicle rushing probability is reduced, and the mountain road can be driven more safely.
