Treatment method of anchor rope within the range of foundation pit envelop enclosure

Abstract

The invention discloses a treatment method of an anchor rope within the range of a foundation pit envelop enclosure and belongs to the technical field of anchor rope treatment. According to the anchorrope treatment method disclosed by the invention, the construction scheme the grab bucket of a hydraulic trenching machine and a rope saw are adopted to cut off the anchor rope is adopted; before encountering the anchor rope, the hydraulic trenching machine is adopted for trenching operation; after encountering the anchor rope, a rope saw rack is detachably mounted on the grab bucket of the hydraulic trenching machine through a dismounting facility A; the grab bucket of the hydraulic trenching machine, the rope saw rack, the rope saw and the dismounting facility A jointly form a hydraulic grab bucket loading and unloading system; then, a hydraulic driving system of the hydraulic trenching machine is connected with a rope saw driving system; the hydraulic driving system of the hydraulic trenching machine drives the rope saw to cut the anchor rope; after the anchor rope is cut off, the hydraulic driving system of the hydraulic trenching machine is disconnected from the rope saw drivingsystem; the rope saw rack is dismantled; and the hydraulic trenching machine continuously carries out trenching operation. With adoption of the anchor rope treatment method, the anchor rope is cut offwhile trenching is carried out to realize the treatment purpose, the safety is high, the construction period is short, and the maneuverability is high.

Description

technical field [0001] The invention belongs to the technical field of anchor cable processing, and in particular relates to an anchor cable processing method within the scope of foundation pit enclosure protection structures. Background technique [0002] In the process of urban construction in our country, with the continuous increase of deep foundation pit projects, prestressed anchor cables have been widely used as an economical and effective means for the construction of civil foundation pit enclosure structures. Compared with other support technologies, the anchor cable has the advantages of low price, simple and mature construction, fast speed, safety and reliability, and does not occupy the main construction work. At the same time, as a temporary support measure, the anchor cable cannot be recycled after the support function fails, and is permanently buried underground together with the built structures and cannot be taken out, forming underground garbage, causing un...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned anchor cable processing method has the following problems: 1. To destroy the original building structure, the project volume is large and coordination is difficult; 2. The original geological structure is destroyed, causing large-scale collapse, and backfilling affects the construction quality of the enclosure structure; 3. Impact drilling The verticality of the hole cannot be guaranteed, and the efficiency is low

Therefore, there are still significant unmet construction needs for urban construction, and it is urgent to develop better anchor cable processing methods
