Embodiment Construction

[0028] Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail

[0029] For the safety protection of the pit wall of the abandoned mine pit 8, it is divided into two major areas, the pit wall safety protection of the area 9 where the main structure of the building is located, and the safety protection of the pit wall of the area 10 where the main structure of the non-house construction is located.

[0030] For the safety protection of the pit wall in the area 9 where the main structure of the house is built, the steps are as follows:

[0031] Step (1) Clean up the dangerous stones, gravels, and weeds on the rock wall 5, measure and locate the holes of the anchor rod 2, and the vertical and horizontal distances of the anchor rod 2 holes are both 4.5m;

[0032] The specific implementation method of measurement and positioning is: use the total station according to the design size and combined with the site terrain t...

Abstract

The invention relates to a construction method of mining pit wall safety protection. The construction method comprises pit wall safety protection measures of a construction area of a house building main structure and pit wall safety protection measures of a non-construction area, wherein the construction method of the construction area of the house building main structure specifically comprises the following steps of (a) cleaning risky rocks, broken stones and weeds on the rock faces in the area in which the house building main structure is located, and measuring and positioning anchor rod holes of a safety net; (b) drilling holes for anchor rods; (c) installing the anchor rods; (d) installing support steel ropes; (e) installing a grilling net; and (f) installing a steel rope net. The construction method has the beneficial effects that the safety net and planting ecological concrete are organically combined with the transformation of waste mining pits, while the safety of waste miningpit housing building and construction is satisfied, the national call to ecological restoration and city repair, i.e. double repairs of cities is responded, and the trend of the construction industryto the direction of environmental protection and sustainable development is satisfied.

Description

technical field [0001] The invention relates to a construction method for rock wall safety protection, in particular to a construction method for mine pit wall safety protection. Background technique [0002] Abandoned mine pits are abandoned lands left after mining activities, and their number and scale have gradually increased over time. During the mining process, the original ecological system was destroyed, and the land occupied by the dump site was basically reclaimed before the mine was closed, while the abandoned open pit was left behind as a direct product after the mine was closed. , Destroying a large amount of land resources in the form of digging damage. Some abandoned mine pits are accompanied by high and steep slopes and accumulated water, which have negative impacts on the ecological environment and landscape to varying degrees. Therefore, the comprehensive treatment and reuse of abandoned open-pit mines is a manifestation of the implementation of circular d...
