Construction method of self-monitoring type slope anti-seismic flexible supporting structure

Abstract

The invention discloses a construction method of a self-monitoring type slope anti-seismic flexible supporting structure. The self-monitoring type slope anti-seismic flexible supporting structure comprises a slope anti-seismic flexible supporting structure and a flexible supporting structure intelligent monitoring system. The slope anti-seismic flexible supporting structure comprises a flexible concrete supporting frame and anti-seismic anchor rods. The supporting method comprises the following six steps: 1, slope repairing; 2, lofting; 3, anchor rod construction; 4, constructing a supporting frame; 5, mounting an anchor head, and tensioning and locking an anchor rod; and 6, switching on a monitoring system. The prestress recovery comprises the following steps: 1, unsealing the anchor head; 2, applying prestress; and 3, sealing the anchor. The problems that under the earthquake action, a traditional slope supporting structure is poor in deformation control capacity and weak in earthquake resistance, and damage of a supporting system after an earthquake cannot be evaluated are effectively solved; the construction method of the self-monitoring type slope anti-seismic flexible supporting structure has the advantages that the anti-seismic concept is advanced, the anti-seismic performance is excellent, the self-monitoring and self-checking functions are achieved, construction is convenient, and construction equipment is miniaturized.

Description

technical field [0001] The invention belongs to the technical field of slope reinforcement, and in particular relates to a construction method of a self-monitoring type anti-seismic flexible support structure for slopes, in particular to a slope support method and a prestress restoration method. Background technique [0002] Earthquake-induced landslides are common geological disasters in mountainous areas. Compared with general landslides, earthquake-induced landslides have significant characteristics such as short time, large scale, and strong destructiveness. In order to prevent landslides caused by earthquake disasters, it is often necessary to carry out seismic protection. [0003] Today’s common forms of slope support include retaining walls, anti-slide piles, micro-piles, anchor frames, etc., but they have the following problems: 1. As passive protective structures, retaining walls, anti-slide piles, and micro-piles cannot Effectively controlling the displacement of ...

[0003] Today’s common forms of slope support include retaining walls, anti-slide piles, micro-piles, anchor frames, etc., but they have the following problems: 1. As passive protective structures, retaining walls, anti-slide piles, and micro-piles cannot Effectively controlling the displacement of the sliding mass and rock-soil mass caused by earthquakes poses a major safety hazard; 2. Although the anchor rod frame has the ability to control deformation, it does not have seismic characteristics. Under the eart
