Expressway slope reinforcement structure

Abstract

The invention discloses an expressway slope reinforcement structure. A plurality of concrete framework beams (3) are arranged in the longitudinal direction of a slope surface, a plurality of anti-rust prestress steel strands (4) subjected to prestress exertion are transversely paved along the slope surface, the anti-rust prestress steel strands (4) are fixedly paved at the upper layer of the concrete framework beams (3), in addition, the two ends of the anti-rust prestress steel strands (4) are respectively and fixedly arranged on a first anchor rod (1) and a second anchor rod (2), and the first anchor rod (1) and the second anchor rod (2) are respectively and fixedly arranged in the rock layers with good mechanical property at the top end of the slop and at the slop foot part of the slope. The expressway slope reinforcement structure has the advantages that on the basis of ensuring the effective reinforcement on the expressway slope, the concrete consumption and the occupied area are reduced, so the greening area is increased; the demand quantity of construction personnel and machinery during the slope reinforcement is reduced, the rock-soil volume during the slope digging is reduced, and the environment pollution and damage is avoided, so the total cost is finally reduced.

Description

technical field [0001] The invention relates to a series of reinforcement measures provided for the reinforcement of the side slope of an expressway, in particular to a reinforcement structure of the side slope of an expressway. Background technique [0002] Slope reinforcement is a very important part of new or expanded highways. At present, most high-speed highway slope reinforcement projects have a large amount of work and a relatively high manpower investment. The construction of vertical frame beams is difficult, and anti-skid Other reinforcement techniques such as piles and anchors are relatively expensive. In view of this situation, in the present invention, the vertical frame beam structure is replaced by steel strands, which can effectively reinforce the slope, which not only greatly reduces the construction amount and manpower input, but also improves the construction progress of the expressway slope reinforcement.
