Abstract
The utility model relates to a deep well dewatering well mouth blocking device in underground garage foundation pit, including setting up the precipitation well in the foundation ditch middle part, set up the filter tube in the above -mentioned precipitation well, the packing sand sets up the immersible pump in precipitation well and the filter tube in the well casing, and the well head sets up the scrobicular ring, set up the gravel layer in the scrobicular ring, the top well head setting of gravel layer covers the steel sheet of well head, concrete layer is laid to the steel sheet top, concrete layer lays second floor steel sheet in the top, second floor steel sheet top sets up the waterproof layer. This worker method can arrange that appropriate precipitation well can high -efficient ground reducing underground water level with common precipitation construction technology in the middle of the foundation ditch for the construction progress shortens construction period, greatly reduced engineering cost, and the shutoff is effectual, and easy operation, work progress easily control construction quality, the phenomenon that seeps water can not appear, and the leaking stoppage effect is more secure.
Description
Technical field
This utility model relates to technical field of building construction.
Background technology
Along with the fast development of urban construction, skyscraper is increasing, and deep foundation pit construction also can be frequently encountered by, and the closure of deep foundation pit precipitation well is the key link of whole foundation construction, and it directly influences this position waterproofing quality.In the engineering construction of In Great Basement and underground garage, for width compared with the foundation ditch big, underground water content is big, foundation ditch width is bigger, while foundation ditch surrounding lays deep well points, dewatering well also need to be set in the middle of soleplate, but this closure terminating rear well head to precipitation brings certain difficulty and trouble.
Utility model content
The technical problems to be solved in the utility model is to provide deep-well precipitation well head well-sealing device in a kind of waterproof effect more preferable underground garage foundation ditch.
For solving above-mentioned technical problem, deep-well precipitation well head well-sealing device in underground garage foundation ditch of the present utility model, including the dewatering well being arranged on foundation ditch middle part, in above-mentioned dewatering well, filter tube is set, sand is filled in dewatering well and filter tube, immersible pump is set in well casing, well head arranges scrobicular ring, in described scrobicular ring, gravel layer is set, the top well head of gravel layer arranges the steel plate covering well head, laying concrete layer above described steel plate, lay second layer steel plate above described concrete layer, described second layer steel plate is provided above waterproof layer.
This engineering method and common dewatering construction technology can lowerings of watertable efficiently at the suitable dewatering well of foundation ditch intermediate arrangement, accelerating construction progress, shorten the construction period, it is substantially reduced construction costs, plugging effect is good, simple to operate, the easily controllable construction quality of work progress, not havinging infiltration phenomenon, plugging effect is more secure.
