Movable blasting protection cover plate

Abstract

The invention provides a movable blasting protection cover plate and belongs to the technical field of blasting construction. The movable blasting protection cover plate comprises a cover plate assembly, a supporting frame and sliding rail assemblies. The material of the movable blasting protection cover plate provided by the invention is a conventional material commonly used on a construction site, and the material is convenient to get. Meanwhile, the material of the movable blasting protection cover plate can also be gotten from remaining or wasted materials to achieve the effect of changingwaste into valuable on the site, and the materials can be repeated used. Secondary utilization of the materials is ensured. Waste of the materials is reduced. The movable blasting protection cover plate is an independent unit and can be independently used. The multiple independent units can also be combined for use, and the site practicality is high. The movable blasting protection cover plate can be quickly moved and installed, and is quick in disassembling and assembling, reusable, convenient to construct on site and capable of protecting the safety of surrounding construction personnel tothe maximum extent.

Description

technical field [0001] The invention belongs to the technical field of blasting construction, and in particular relates to a movable blasting protection cover. Background technique [0002] During the excavation of the foundation pits of today’s subway stations, domestic foundation pit blasting protection measures mainly cover the surface of the blasting area: pile up sand bags around the blast holes, that is, use woven bags to hold crushed soil or sand, and there must be no small stones; then cover the sand bag with barbed wire, and exceed the blasting range by more than 1m; finally press a small amount of sand bag on the barbed wire, or place a layer of protective cover on the first layer of concrete support of the foundation pit, etc. The blasting protection measures for the foundation pit require a lot of manpower and materials to ensure the smooth completion of the excavation of the foundation pit in the above-mentioned processes. The above-mentioned construction method...

AI Technical Summary

Problems solved by technology

However, with the continuous improvement of the construction progress of the foundation pit and the continuous increase of construction machinery and labor costs, the use of the above construction process will greatly increase the construction investment. Reciprocating the blasting area to cover the surface requires not only a lot of manpower, but also Seriously affect the progress of the site

When the surface of the blasting area is used to cover the above process, due to the cumbersome procedures, the site construction takes a long time, which affects the site construction progress, and there are many safety hazards in the construction process, resulting in large economic investment and material waste
