Description
Technical Field
The utility model relates to the field of building construction, in particular to a basement dewatering vacuum deep well structure.
Background
At present, a deep foundation pit dewatering well generally adopts a sand-free cement pipe deep well for dewatering, and has the advantages of rapid construction, large drainage quantity, deep dewatering, good drainage effect, large well spacing and the like. The deep foundation pit dewatering well is buried in the foundation pit, and the shutoff of well head becomes difficult problem. The conventional plugging device is easy to leak in the plugging process or after plugging, the treatment is time-consuming and labor-consuming, and the plugging is not thorough. After precipitation is finished, great difficulty is brought to plugging of a wellhead, and the well becomes a weak link of deep well precipitation. If the plugging of the wellhead of the deep well is not good, the phenomena of serious slurry leakage and cavities of concrete are easy to occur, the strength and the durability of the structure are influenced, the water leakage of the concrete is also caused, and the normal use of the engineering is seriously influenced.
Disclosure of Invention
The utility model aims to solve the technical problem of deep well precipitation plugging in the prior art and provides a basement precipitation vacuum deep well structure.
In order to achieve the purposes, the technology adopted by the utility model is as follows:
a basement precipitation vacuum deep well structure comprises a leakage hole steel pipe and a water suction pump, wherein the leakage hole steel pipe is inserted below a basement bottom plate, the outer wall of the leakage hole steel pipe is sleeved with a steel mesh, an aggregate filling layer, a rapid hardening cement layer and a polyurethane grouting layer are sequentially arranged in the leakage hole steel pipe from bottom to top, an upper steel pipe is coaxially arranged at the top end of the leakage hole steel pipe, and the upper steel pipe is inserted in the leakage hole steel pipe; the upper steel pipe is buried in a basement bottom plate layer, a first steel plate is welded at the middle upper part in the upper steel pipe, a second steel plate is welded at the top end of the upper steel pipe, grouting materials are filled below the first steel plate in the upper steel pipe, and micro-expansion concrete is filled between the first steel plate and the second steel plate; and a water pumping pipe of the water pump penetrates through the upper steel pipe and the leak hole steel plate and is inserted into the sandstone material filling layer.
Furthermore, a grouting pipe is installed in the middle of the first steel plate, external threads are arranged outside the grouting pipe, and a plug is installed on the grouting pipe through threads.
And furthermore, a water stop ring is welded on the outer wall of the upper steel pipe.
After the technical scheme is adopted, the utility model has the beneficial effects that: and a plurality of filling layers are arranged in the leak hole steel pipe, so that the upward leakage of the underground water is avoided. The top of the steel pipe with the leakage hole is additionally provided with an upper steel pipe, and the upper steel pipe is further plugged by two plugging steel plates and a filling layer to prevent high-pressure underground water from leaking. And a pipe plug is arranged on one of the steel pipes, so that the steel pipes can be plugged in time after grouting. The technical scheme has good plugging effect, is suitable for occasions with large underground water pressure, can recycle the upper steel pipe, and saves cost.
