High slope earthwork and support engineering construction method

Abstract

The invention discloses a high slope earthwork and support engineering construction method which comprises the following steps of: carrying out construction measurement, pay-off and positioning; clearing and excavating a temporary drainage ditch; excavating a first layer of earthwork of a current-class slope; finishing a side slope of the current-class slope; drilling on the current-class slope according to a preset anchor cable installation position to form an anchor cable mounting hole; manufacturing and installing an anchor cable on the current-class slope; grouting the anchor cable mounting hole on the current-class slope; excavating a lower layer of earthwork of the current-class slope; constructing a waist rail on the current-class slope; carrying out prestressed anchor cable tensioning and locking on the current-class slope; sealing and anchoring the current-class slope; repeating the construction step of the current-class slope and completing the construction of a subsequent-class slope; and monitoring the side slope. Due to the adoption of the high slope earthwork and support engineering construction method disclosed by the invention, the high slope earthwork and support engineering construction method capable of effectively ensuring the stability of the side slope after the side slope is excavated is implemented. The high slope earthwork and support engineering construction method has the characteristics that after construction, a rock-soil body has stable structure; the process is simple and convenient; the high slope earthwork and support engineering construction method is safe to construct; the investment of large-scale mechanical equipment is reduced; and the cost is saved.

Description

technical field [0001] The invention relates to a construction method, in particular to a high slope earthwork and support engineering construction method. Background technique [0002] At present, during the construction of earthwork excavation and support projects for high and large mountain slopes, expressway slope support projects, earthwork excavation and filling of large public sites, and slope support projects, due to the large undulations of the terrain and complex geological conditions, the development of Problems of slope deformation and damage are often encountered during excavation. At present, there is still a lack of a high slope earthwork and support engineering construction method that can effectively ensure the stability of the slope after excavation. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a high slope earthwork and support engineering construction method, which reali...
