Safety covering system for foundation pit blasting in complex environment and covering method

Abstract

The invention belongs to the technical field of building blasting, and particularly relates to a safety covering system for foundation pit blasting in a complex environment and a covering method The safety covering system for foundation pit blasting in the complex environment is provided with a rubber mat, a straw mat layer, a dense mesh type safety net and a sandbag from bottom to top. A plurality of holes are formed in the four edges of the rubber pad, a buckle is arranged on each hole, four fixing frames are arranged around the rubber pad, and each fixing frame penetrates through the holes in the same row of the rubber pad. The covering method of the safety covering system for foundation pit blasting in the complex environment comprises the steps of weaving of the rubber mat, lap joint of the straw mat and covering of the sandbag. By means of the safety covering system composed of the rubber mat, the straw mat layer and the dense mesh type safety net, safety protection on blasting operation is well achieved.

Description

technical field [0001] The invention belongs to the technical field of building blasting, and in particular relates to a safety covering system and covering method for foundation pit blasting in complex environments. Background technique [0002] Urban foundation pit blasting operations usually have a very complex surrounding environment and are close to surrounding structures and buildings, and most of them have cross operations. The blasting flying objects must be strictly controlled to prevent damage to surrounding personnel, facilities and structures. The traditional foundation pit blasting covering system has the following disadvantages: in order to ensure the covering effect, steel plates are often used for covering. Steel plates are large in size and heavy in weight, requiring the use of cranes and other machinery for hoisting. The approval process is cumbersome, takes a long time, and requires professionals to operate, and the efficiency of blasting and covering cons...

AI Technical Summary

Problems solved by technology

Steel plates are large in size and heavy in weight, requiring the use of cranes and other machinery for hoisting. The approval process is cumbersome, takes a long time, and requires professionals to operate, and the efficiency of blasting and covering construction is slow; when steel plates are not used, other covering materials are used, and mechanical operations are limited. Due to the narrow working face of the foundation pit, it is often difficult to operate

Manual operation is labor-intensive, time-consuming and labor-intensive; the covering material is difficult to form a whole, and it is difficult to ensure that no flying objects overflow in local areas
