Embodiment Construction

[0024] Attached below Figure 1-4 And embodiment, the present invention is described further.

[0025] A pit-in-pit steel drum dewatering method, the implementation steps are: making a cylindrical steel drum (1) with a diameter of 800 mm to 1200 mm and a thickness of 5 mm, the height of which is determined by the thickness of the poured raft. Holes are opened at the bottom of steel drums (1) and gate valves (2) are installed, and water-stop rings (4) are welded around each 3000mm long steel drum (1). (8) Fill the bottom with a thickness of 100mm, introduce the water from other leaking points into the pit through the blind ditch, then put the steel drum (1) into the pit filled with the centimeter stone (8), and then use the centimeter stone (8) Fill up around the bottom of the steel drum (1), fill the blind ditch with dog head stones (6), and cover with a plastic film (7). Water from other leaking points is introduced into the deep pit through the blind ditch and enters throu...

Abstract

The invention discloses a method for discharging water in a pit through a steel bucket in the pit. According to the method for discharging water in the pit through the steel bucket in the pit, a hole is formed in the bottom of the cylindrical steel bucket (1), a gate valve (2) is installed in the orifice of the hole, waterstop rings (4) are welded to the surface of the outer wall of the steel bucket (1), the steel bucket is placed in the pit filled with centimeter-level stone (8), and then the periphery of the bottom of the steel bucket is filled with centimeter-level stone; a blind ditch is filled with dog-head-shaped stone (6), and water existing in other water leakage points is guided into the steel bucket from the orifice of the hole through the blind ditch; a water pump (3) is placed in the steel bucket so that water can be pumped. According to the method for discharging water in the pit through the steel bucket in the pit, it can be guaranteed that water falls into the steel bucket in the whole raft construction process, the whole foundation pit is in a water-free construction state, waterproof construction and other processes are greatly facilitated, the phenomenon that water leakage and cracks happen to a raft due to underground water is avoided, the concrete casting quality of the raft is guaranteed, and water discharging can be achieved conveniently and effectively.

Description

technical field [0001] The invention relates to the water stop of deep foundation pits in the construction industry, in particular to a pit-in-pit steel drum drainage method. Background technique [0002] Construction projects in places with rich groundwater, especially deep foundation pit projects, have a large amount of underground water inflow, and corresponding water-stop measures must be taken during construction to ensure the smooth progress of construction. [0003] Waterstop methods for deep foundation pits usually include: waterstop curtain, well point precipitation and drainage ditches; however, there are deficiencies such as long construction period, complicated operation and high cost. become poorly or almost ineffective. Contents of the invention [0004] The object of the present invention is to provide a pit-in-pit steel drum drainage method for the deficiencies in the above-mentioned prior art. The invention can keep the steel barrels in the whole raft co...
