Abstract
The present invention relates to basement bottom boards.Basement bottom board plugging dewatering well method, it includes: step 1, concentrates the water in extraction dewatering well with water pump；Step 2, rubber ring rivet interlacement in steel pallet；Step 3, the two welds together after the coating steel pipe that diameter is 20-30mm is passed through steel pallet；Upper part stretches out plate upper surface, and is bent and is placed in base surface, which is provided with sealing valve；Coating steel pipe after valve reserves one end length, makes it possible to connect with rubber hose；Step 4 is placed into steel pallet in dewatering well, makes the gap between rubber ring supporting plate closed as far as possible and dewatering well；Step 5 pours the part that high grade rapid hardening water-tight concrete is located at bottom plate to dewatering well；Step 6 closes sealing gate valve after concrete strength reaches design strength, and spot welding is lived；To be buried underground in the building screed-coat of room.Base plate leakage problem caused by effective solution of the present invention precipitation deficiency, provides against hidden trouble.
Description
Technical field
The present invention relates to basement bottom board more particularly to the dewatering wells of basement bottom board.
Background technique
In practice of construction, the dewatering well of basement is completed or is basically completed in building structure construction, meets design
After anti-floating requires, just start to block.Since the underground water in dewatering well is many times artesian water, water is again bigger, especially
It is when blocking the last one dewatering well, these unfavorable factors, which seem, especially to be concentrated.Handle bad, precipitation well area easily forms bottom
Plate leakage, and the position later period is difficult to handle.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, a kind of basement bottom board plugging dewatering well method is provided.The present invention
Base plate leakage problem caused by effective solution precipitation deficiency, provides against hidden trouble.
In order to solve the above-mentioned technical problem, basement bottom board plugging dewatering well method, it includes:
Step 1 concentrates the water in extraction dewatering well with water pump；
Step 2, rubber ring rivet interlacement in steel pallet；
Step 3, the two welds together after the coating steel pipe that diameter is 20-30mm is passed through steel pallet；Upper part stretches out bottom
Plate upper surface, and be bent and be placed in base surface, which is provided with sealing valve；It is long that coating steel pipe after valve reserves one end
Degree, makes it possible to connect with rubber hose；
Step 4 is placed into steel pallet in dewatering well, makes the gap between rubber ring supporting plate closed as far as possible and dewatering well；
Step 5 pours the part that high grade rapid hardening water-tight concrete is located at bottom plate to dewatering well；
Step 6 closes sealing gate valve after concrete strength reaches design strength, and spot welding is lived；To be buried underground room
It builds in screed-coat.
The basement bottom board plugging dewatering well method, in the step 5, the dewatering well crystalline substance is located at the portion of bottom plate
Divide and reserved when constructing bottom plate, lateral surface is provided with dense mesh.
The basement bottom board plugging dewatering well method, it further includes, if artesian pressure is especially big, sealing gate valve is closed
It closes not tight, then the reserved end of the coating steel pipe after valve is connected with rubber hose, rubber hose is pre-buried to basement edge
Gutter in, formed functional in organized water drainage.
The present invention is mainly connected by the steel dewatering well, steel pallet, rubber ring, rubber ring and the steel pallet that are embedded in floor bottoms
Rivet, coating steel pipe, the sealing gate valve, the rubber hose composition to match with coating steel pipe connect.Effective solution of the present invention
Base plate leakage problem caused by precipitation deficiency, design is rationally, easy to implement, provides against hidden trouble.
Specific embodiment
A kind of basement bottom board plugging dewatering well method of the present invention is mainly 300mm by the diameter for being embedded in floor bottoms
Steel dewatering well, diameter be 295mm the steel pallet with a thickness of 3mm, the width with a thickness of 5mm be the rubber ring of 50mm, rubber
Rivet that rubber ring is connect with steel pallet, diameter are 20(or 30mm, and view water yield size is chosen) coating steel pipe, sealing gate valve and
The rubber hose composition that coating steel pipe matches.
When construction:
1, the water in extraction dewatering well is concentrated with water pump；
2, the steel support with a thickness of 3mm for being 295mm in diameter with rivet interlacement the rubber ring that the width with a thickness of 5mm is 50mm
On plate.
3, it is 20(or 30mm diameter) coating steel pipe is across steel pallet about 50mm, and the two welds together later.Thereon
Plate upper surface is slightly stretched out in portion, and is bent and is placed in base surface, which is provided with sealing valve.Coating steel pipe after valve is pre-
One end length is stayed, makes it possible to connect with rubber hose.
4, steel pallet is placed into dewatering well, makes the gap between rubber ring supporting plate closed as far as possible and dewatering well.
5, high grade rapid hardening water-tight concrete to dewatering well is poured to be located at the part of bottom plate (section is pre- when constructing bottom plate
It stays, lateral surface is provided with dense mesh.)
6, after concrete strength reaches design strength, sealing gate valve is closed, spot welding is lived.It is buried underground the building of room in the future
In screed-coat (the thickness degree is typically designed as 100mm, completely can be with embedding gate valve).
If 7, artesian pressure is especially big, sealing gate valve is not closed completely, then the reserved end of the coating steel pipe after valve with
Rubber hose connects, and rubber hose is pre-buried in the gutter of basement edge, forms functional in organized water drainage.
