Problems solved by technology

However, due to the reverse method of construction, due to the excavation of earthwork layer by layer, there are many large-scale construction machinery and equipment on the B0 board, and the on-site dust reduction pressure is high. It is difficult to achieve full coverage of the B0 board for car dust suppression
In addition, because the dust removal water of sprinklers is mostly supplied by fire protection or municipal pipe network, the large water consumption causes waste of water resources

Embodiment 1

[0034] combine figure 1 As shown, a barrier-free and full-coverage dust suppression system for an inverted platform includes a BO board 1, a B1 board 2, and a precipitation well 9. Several sprinkler heads 3 are installed on the BO board, and a reservoir 5 is provided on the B1 board. The sprinkler head and the reservoir are connected through a water supply pipeline 6 arranged between the BO board and the B1 board, and a booster pump 4 is installed on the water supply pipeline, and the positions of the reservoir and the booster pump are preferably Near Exit 14. The upper end of the water supply pipe is fixed to the lower surface of the BO board through the pipe fixing buckle 7 .

[0035] A dewatering well pump 11 is installed between the reservoir and the dewatering well. One end of the dewatering well dewatering pump is connected with the dewatering reservoir through the water inlet pipeline 8, and the other end is connected with the dewatering well through the dewatering wel...

Embodiment 2

[0043] combine figure 2 As shown, the difference from Example 1 is that the BO plate is provided with a sedimentation tank 10 , and preferably, the sedimentation tank is located close to the excavation port 14 . The settling tank is installed on the water inlet pipeline between the water pump of the dewatering well and the water storage tank. The sedimentation tank is used to collect rainwater and well water, and then provides water for the storage tank through the water inlet pipe 8 .

[0044] The installation method of the barrier-free full-coverage dust suppression system of the inverted platform in this embodiment is different from the installation method of the structure shown in Embodiment 1 in that the step S1 also includes arranging the sedimentation tank 10 on the BO board, the step S4 also includes installing the sedimentation tank on the water inlet pipeline between the dewatering well pump and the water storage tank.

[0045] The water supply pipe of the present...

Abstract

The invention relates to a barrier-free full-coverage dust falling system of an inverse construction platform. The system comprises a plate B0, a plate B1 and a dewatering well. A plurality of sprinkler heads are arranged on the plate B0, a water storage pool is arranged on the plate B1, and the sprinkler heads are connected with the water storage pool through a water supplying pipeline below the plate B0. A booster pump is arranged on the water supplying pipeline, and a dewatering well water suction pump is arranged between the water storage pool and the dewatering well. According to further improvement, the system comprises a sedimentation pool which is arranged on a water inflow pipeline between the dewatering well water suction pump and the water storage pool is arranged on the plate B0. The invention further provides an installing method for the barrier-free full-coverage dust falling system of the inverse construction platform. According to the barrier-free full-coverage dust falling system of the inverse construction platform and the installing method, inconvenience brought to driving and construction when temporary hoses are dragged in the prior art is avoided, water sprinkling coverage of the system can cover the whole construction area, and thus dust falling efficiency is greatly improved.

Description

technical field [0001] The invention relates to a barrier-free full-coverage dust suppression system for an upside-down method platform, specifically, a barrier-free full-coverage dust reduction system and an installation method that combine the construction characteristics of the upside-down method and are applied to the upside-down method BO board platform, which belongs to the clean and environmental protection of building construction technology field. Background technique [0002] The upside-down method is a method of underground structure construction. Generally, the underground continuous wall is constructed along the basement exterior wall, or other temporary maintenance walls are constructed along the periphery of the foundation pit, and at the same time, intermediate support piles and columns are poured or laid down at relevant positions inside the building. As a vertical support to bear the self-weight and construction load of the superstructure during the constru...
