Intelligent two-way traction dust falling curtain net system for large-span foundation pit construction

Abstract

The invention relates to the technical field of foundation pit construction, in particular to comprehensive prevention and control of a foundation pit construction environment, and discloses an intelligent two-way traction dust falling curtain net system for large-span foundation pit construction. The system comprises a plurality of groups of supporting structures; each supporting structure comprises a local side supporting unit and an opposite side supporting unit; a direction pulling cable is arranged between the local side supporting unit and the opposite side supporting unit; a protective curtain is arranged on the direction pulling cable; the protection system further comprises a two-way traction mechanism; the two-way traction mechanism comprises a driving traction cable connected and matched with the protection curtain; and the driving traction cable pulls the protective curtain to the middle of a foundation pit or the edge of the foundation pit at the same time. A two-way traction structure is adopted, so that curtain net protection of a large-span foundation pit can be achieved, the requirement for the strength of the protective curtain is lowered, the efficiency of curtain net protection operation is further improved, curtain net protection is opened and closed through automatic and intelligent operation, and treatment of the construction environment at the foundation pit is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of foundation pit construction, in particular to comprehensive prevention and control of the foundation pit construction environment, and discloses an intelligent two-way traction and dust-reducing screen net system for large-span foundation pit construction. Background technique [0002] In the current foundation pit construction projects, especially in urban foundation pit construction, there is a phenomenon of suspended particle dust pollution such as PM2.5 and PM10 inside the foundation pit. After a certain stage of construction, the dust in the foundation pit rises into the air. If If it is not treated, it will cause damage to the surrounding environment and affect the ambient air. [0003] The existing method is to cover the construction raw materials to prevent the construction raw materials from raising dust and entering the air, and at the same time, properly spray or spray dust on the construction ...

Problems solved by technology

[0004] But in fact, the existing construction environment management measures need to consume a lot of human resources, and the covering treatment is a one-time operation, which will affect the subsequent use of raw materials, so the covering operation will be repeated many times; it not only increases the labor intensity, but also affects Improve construction efficiency and reduce construction progress
