Rock foundation small guide pipe partial water level lowering device and implementation method thereof

Abstract

The invention relates to a device and an implementation method thereof, in particular relates to a rock foundation small guide pipe partial water level lowering device and an implementation method thereof. The rock foundation small guide pipe partial water level lowering device is characterized in that a PVC (Polyvinyl Chloride) water filter pipe is connected with a PVC connection pipe, wherein the PVC connection pipe is connected with a steel guide pipe; the steel guide pipe is connected with an annular water stopping steel plate; rubber water discharging pipes are inserted into pipes for connecting the steel guide pipe, the PVC connection pipe and the PVC water filter pipe. With the adoption of the technical scheme, the rock foundation small guide pipe partial water level lowering device has the advantages and active effects that the operation is simple, the construction is convenient, the technical difficulty is low, the pertinence on water precipitation and drainage regions is strong and the arrangement is flexible; the cost is low, natural drainage is realized by sufficiently utilizing underground water, and the energy source consumption is reduced; the underground water level can be effectively reduced, a foundation keeps dry and the construction of other procedures is not influenced; a foundation working surface can be more rapidly provided and the engineering progress is effectively promoted; the construction quality is guaranteed and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a device and its implementation method, in particular to a rock foundation small conduit local precipitation device and its implementation method. Background technique [0002] At present, due to the impermeability of the rock foundation, the infiltration of water in the rock foundation is distributed according to the direction of the rock crevices, and the groundwater cannot be discharged even if the rock crevices are separated by a very small distance. Light well points (multi-level light well points) are used, and the precipitation depth is between 3 and 6m, which is limited for deep foundation pits, but cannot be realized for rock foundations. Although the advantages of using deep well point precipitation are large displacement, large precipitation depth, and large precipitation range, for rocky foundations, the drilling cost is high and the construction period is long. The use of open ditch drainage requires a large amoun...

AI Technical Summary

Problems solved by technology

[0002] At present, due to the impermeability of the rock foundation, the infiltration of water in the rock foundation is distributed according to the direction of the rock crevices, and the groundwater cannot be discharged from the rock crevices with very little spacing.

Light well points (multi-level light well points) are used, and the precipitation depth is between 3 and 6m, which is limited for deep foundation pits, but cannot be realized for rock foundations

The use of deep wells for precipitation has the advantages of large displacement, large precipitation depth, and large precipitation range, but for rocky foundations, the drilling cost is high and the construction period is long.

The open ditch is used for drainage, and the excavation volume is large. There should be enough space on the construction site, but the groundwater in the rock foundation cannot be completely excluded.
