Problems solved by technology

[0002] Roads built along the mountain have higher structural strength requirements than those built on a flat surface. The existing construction method requires multiple downward anchors to be driven into the roadbed for ground reinforcement, but Many mountain structures are stone structures, and the depth of the vertically driven anchor rods is relatively large, so the construction is difficult, and in this construction method, the number of vertically driven anchor rods needs to be uniform, and the number is very large. construction costs are very high

Embodiment 1

[0039]A municipal road reinforcement device, comprising a plurality of steel rods 1 embedded in the cushion layer, the steel rods 1 are hollow structures, the right ends of the steel rods 1 extend to the outside of the cushion layer, and the left ends of the steel rods 1 are inserted into the There is an insertion rod 2, and the insertion rod 2 is driven into the mountain body; the front and rear end faces of the steel plate 1 are provided with export grooves 101 for exporting concrete slurry; the outside of the steel rod 1 is equipped with a wall plate 3 , the wall plate 3 forms a limit on the outside of the cushion, and the lower end of the wall plate 3 is inserted into the soil layer; a rib plate 301 is welded on the outer side of the wall plate 3, and the lower end of the rib plate 301 acts as On the top of the steel plate 1; the top position of the part of the steel rod 1 located in the cushion layer is provided with a socket 102, and an anchor rod 4 is inserted in the soc...

Embodiment 2

[0041] The upper end of the wall plate 3 is bent horizontally to form an assembly part 311, and the top of the assembly part 311 is vertically penetrated with an assembly hole 312 for installing a guardrail; the above-mentioned structure is mainly for installing a side guardrail. In the above-mentioned structure, The fitting part 311 is located on the outside of the road, so the passing width of the road surface can be increased.

Embodiment 3

[0043] A plurality of perforations 103 are provided on the longitudinal end surface of the part of the steel rod 1 extending to the outside of the cushion; the perforation 103 runs through the steel rod 1 in a longitudinal direction, and passes through the The perforation 103 is equipped with a steel cable 6, and the steel cable 6 is grouted after the perforation is completed, and the concrete grout is solidified to cover the steel cable 6, and the steel cable 6 blocks the perforation 103; the above structure Among them, the width of the steel pole 1 extending to the outside of the road surface is greater than 2 meters, and the distance between adjacent steel cables 6 is controlled at 14cm. Through the above structure, after the vehicle collides with the side guardrail and causes the side guardrail to fail, the steel cable 6 can pass through. Undertake the vehicle to prevent the vehicle from falling off the cliff, and a gap is formed between adjacent steel cables 6. The existen...

Abstract

The invention discloses a municipal road reinforcing device and a construction method. The municipal road reinforcing device comprises a plurality of steel rods buried in a cushion layer, the steel rods are of hollow structures, the right ends of the steel rods extend out of the cushion layer, inserting rods are inserted into the left ends of the steel rods, and the inserting rods are knocked into a mountain; the front end face and the rear end face of the steel plate are each provided with a guiding-out groove used for guiding out concrete grout. a wall plate is assembled outside the steel rod, the wall plate is limited outside the cushion layer, and the lower end of the wall plate is inserted into the soil layer; and rib plates are welded in the outer sides of the wall plates. According to the device and method, the mountain road can be reinforced, and the construction cost is low.

Description

technical field [0001] The invention relates to a municipal road reinforcement device and a construction method. Background technique [0002] Roads built along the mountain have higher structural strength requirements than those built on a flat surface. The existing construction method requires multiple downward anchors to be driven into the roadbed for ground reinforcement, but Many mountain structures are stone structures, and the depth of the vertically driven anchor rods is relatively large, so the construction is difficult, and in this construction method, the number of vertically driven anchor rods needs to be uniform, and the number is very large. Construction costs are very high. [0003] For this reason, we have designed a municipal road reinforcement device and construction method that can reinforce mountain roads and have low construction costs. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a muni...
