Embodiment 1
[0035] see figure 1 , the present embodiment proposes a foundation pit support 51 spraying construction dustproof structure, including:
[0036] A track structure, the track structure includes a moving track 10 installed on the top of the edge of the foundation pit 50 and surrounding the edge of the foundation pit 50;
[0037] A moving structure, the moving structure includes a plurality of moving seats 21 capable of moving along the extending direction of the moving track 10, and the plurality of moving seats 21 are arranged in sequence along the moving track 10;
[0038] Dust-proof structure, the dust-proof structure includes the cantilever arm 31 corresponding to the number of the dust-proof curtain 32 and the mobile seat 21, the cantilever arm 31 is correspondingly installed on the corresponding mobile seat 21 and extends into the foundation pit 50, so The dust-proof curtain 32 is arranged below the cantilever arm 31, and the top of the dust-proof curtain 32 is connected ...

The invention discloses a dust-proof structure for foundation pit support spraying construction and a method for using the same, and relates to the technical field of foundation pit construction. The invention mainly uses dust-proof curtains to make the foundation pit support splash out when the spraying treatment is performed. The sprayed concrete and dust can be hindered by the dust curtain, thereby reducing the environmental impact of the foundation pit support shotcrete construction on the construction phenomenon. More importantly, the dust-proof curtain is installed on the moving track surrounding the entire foundation pit, so the implementer can realize the dust-proof operation for the entire foundation pit only by setting a small-area dust-proof curtain. The setting has the obvious advantages of low implementation cost and high implementation efficiency.
Description
technical field [0001] The invention relates to the technical field of foundation pit construction, in particular to a dust-proof structure for foundation pit support spraying construction and a use method thereof. Background technique [0002] Foundation pit support is a strengthening member arranged at the edge of the foundation pit. Many types of foundation pit support (such as anchor shotcrete support, pile row support) will adopt the spraying construction process in the construction process. However, the use of shotcrete construction has a great impact on the environment of the project site. The sprayed concrete is prone to dust and splashes. The construction personnel in the foundation pit need to evacuate temporarily, which has a certain impact on the construction efficiency of the entire project. Accordingly, how to reduce the environmental impact of the foundation pit support spraying construction process on the project has become an urgent technical problem to be s...
