Foundation drainage device and manufacturing method and using method thereof

Abstract

The invention provides a foundation drainage device and a manufacturing method and a using method thereof. The foundation drainage device comprises a water collecting pipe, a plurality of water diversion pipes and a necking piece, wherein the water collecting pipe is a hollow pipe fitting with two open ends, and a plurality of first holes are formed in the side wall of the bottom end of the watercollecting pipe; the water diversion pipes are arranged on the periphery of the water collecting pipe, the water diversion pipes are hollow pipe fittings and are connected to the side wall of the water collecting pipe through the end parts, cavities of the water diversion pipes communicate with a cavity of the water collecting pipe, and a plurality of second holes are formed in the side walls of water diversion pipes; and the necking piece is a hollow pipe fitting with two open ends, the cross-sectional shape of the necking piece is matched with the upper end opening of the water collecting pipe, a plurality of notches are formed in the lower end of the necking piece in the circumferential direction, and each notch is in a big-end-down shape. The foundation drainage device effectively removes groundwater.

Description

technical field [0001] The invention relates to the technical field of foundation drainage, in particular to a foundation drainage device, a method for making the device, and a method for using the device. Background technique [0002] At present, in the process of deep foundation pit replacement, large-area squares, and stockyard rolling, the groundwater rises due to the vibration generated during rolling, which seriously affects the quality of foundation pit replacement, which will cause foundation pits, squares, and stockyards to be replaced. The material cannot be rolled and compacted. The groundwater cannot be drained but is contained in the base soil layer, which cannot meet the compactness required by the design, so that it cannot meet the bearing capacity of deep foundation pits, squares or stockyard replacement. Especially when deep foundation pits are replaced and filled, due to the soaking effect of groundwater, after the first layer is replaced, the groundwater ...

AI Technical Summary

Problems solved by technology

Since the foundation pit and the foundation part are rolled (tamped) layer by layer during the replacement, the groundwater rise in the foundation pit or the foundation is extremely difficult to deal with, and the general dewatering method cannot control or eliminate the groundwater in the middle of the foundation pit and the foundation

During the replacement and rolling, rubber soil or spring soil will appear in the backfill of the base, which will affect the quality of the base and the quality of the upper concrete structure
