Embodiment 1

[0026] This embodiment discloses a screen driving mechanism, such as figure 1 , image 3 As shown, the details are as follows:

[0027] An intelligent two-way traction and dust-reducing screen driving mechanism for large-span foundation pit construction, including several sets of support structures relatively arranged on both sides of the foundation pit, each set of support structures includes a correspondingly matched local support unit 1 and an opposite side support protection unit 2; a direction traction cable 12 is arranged between the support unit 1 on this side and the support unit 2 on the opposite side, and the protection system also includes a two-way traction mechanism. The traction cable 6 comprises bidirectional traction sections parallel to the protective screen 3 and driven in opposite directions.

[0028] The drive mechanism disclosed above is arranged at the foundation pit, and is used in the protective curtain system above the foundation pit, and the shieldi...

Embodiment 2

[0037] In view of the fact that the top protective structure needs to be manually set up in the existing foundation pit construction, which consumes a lot of human resources, and has low efficiency and high cost, this embodiment is optimized to solve the problems in the prior art.

[0038] Specifically, such as figure 1 , figure 2 As shown, this embodiment discloses an intelligent two-way traction and dust suppression screen system for large-span foundation pit construction, including several sets of support structures relatively arranged on both sides of the foundation pit, each set of support structures includes corresponding matching side supports Support unit 1 and opposite side support unit 2; Direction traction cable 12 is set between this side support unit 1 and opposite side support unit 2, and at least one direction traction cable 12 is set on the direction traction cable 12 from this side support unit 1 to the foundation pit The protective curtain 3 extending in th...

Abstract

The invention relates to the technical field of foundation pit construction, in particular to comprehensive prevention and control of foundation pit construction environments, and discloses an intelligent bidirectional traction dust falling curtain net driving mechanism for large-span foundation pit construction. The mechanism comprises multiple supporting structures oppositely arranged on the two sides of a foundation pit; each supporting structure comprises a local-side supporting unit and an opposite-side supporting unit which are correspondingly matched; a direction traction cable is arranged between each local-side supporting unit and the corresponding opposite-side supporting unit; a protection system further comprises a bidirectional traction mechanism; a driving traction cable is a circulating cable connected end to end, and the driving traction cable comprises bidirectional traction sections which are parallel to a protection curtain and are opposite in driving direction. The bidirectional traction structure is adopted, curtain net protection of the large-span foundation pit can be achieved, the requirement for the strength of the protection curtain is lowered, the efficiency of curtain net protection operation is further improved, curtain net protection is started and stopped 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 the comprehensive prevention and control of the foundation pit construction environment, and discloses an intelligent two-way traction and dust-reduction curtain net driving mechanism 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 ...
