Abstract
The present invention relates to a kind of self priming pumps to reduce local groundwater level construction method, includes the following steps: to cheat in catch pit bottom close to catch pit side-walls setting casual water；Using large-sized rubble 3 filling casual water hole, the embedding pvc pipe in rubble filling process；Self priming pump is set at the top of catch pit, the draining pipe end of self priming pump wraps up fine and closely woven mesh filter screen, puts in pre-buried pvc pipe；Water level is drawn water using self priming pump at any time in pvc pipe, discharges into gutter；Before underplate concrete pours, water level is reduced using self priming pump first, before water level recovery, fusing pvc pipe is completed, uses waterproof roll closure construction operation；Casting concrete is quickly concentrated, guarantees that sealing part is tight by concrete gravity.Self priming pump of the present invention reduces local groundwater level construction method, securely and reliably, improves construction efficiency, reduces labor intensity of workers, reduce construction cost, guarantees construction quality.
Description
Technical field
The present invention relates to a kind of construction techniques, in particular to a kind of self priming pump reduces local Groundwater
Position construction method.
Background technique
It is deposited since level of ground water can not be perfectly controlled by dewatering well excavation of foundation pit part position (such as catch pit etc.)
It is temporarilly reduced in local level of ground water needs.
Existing part level of ground water, which temporarilly reduces method, reduces water level using sewage pump, will be dirty during waterproof construction
Water pump is shut in catch pit with lower portion to guarantee precipitation at any time.Existing part level of ground water temporarilly reduces method for sewage pump
It shuts and causes huge waste in catch pit, while needing to provide power supply to sewage pump, there are some potential safety problemss, are easy hair
Raw failure, drainage effect are poor.
Summary of the invention
In view of the deficiency of the prior art, the present invention provides a kind of safe and reliable, improves construction efficiency, reduces worker
Labor intensity, the self priming pump for reducing construction cost reduce local groundwater level construction method.
The technical solution used in the present invention is:
A kind of local groundwater level construction method of self priming pump reduction, includes the following steps:
1) it is cheated in catch pit bottom close to catch pit side-walls setting casual water；
2) using large-sized rubble 3 filling casual water hole, the embedding pvc pipe in rubble filling process；
3) it after the completion of the filling of casual water hole, is compacted using cement mortar, is levelling；Reserved when catch pit construction of waterproof layer
Side is received at pvc pipe；
4) self priming pump is set at the top of catch pit, the draining pipe end of self priming pump wraps up fine and closely woven mesh filter screen, puts in pre-buried
In pvc pipe；Water level is drawn water using self priming pump at any time in pvc pipe, discharges into gutter；
5) before underplate concrete pours, water level is reduced using self priming pump first, before water level recovery, completes fusing
Pvc pipe uses waterproof roll closure construction operation；
6) casting concrete is quickly concentrated, guarantees that sealing part is tight by concrete gravity.
Casual water hole position is arranged other than catch pit reinforcing bar orientation.
The pvc pipe diameter is greater than the diameter of self-priming pump drain pipe, opens up inlet opening in pvc pipe side wall.
The present invention compared with the prior art the utility model has the advantages that
Self priming pump of the present invention reduces local groundwater level construction method, securely and reliably, improves construction efficiency, reduces worker
Labor intensity reduces construction cost, guarantees construction quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that self priming pump of the present invention reduces local groundwater level construction method；
After Fig. 2 is the catch pit foundation pit casting concrete that self priming pump of the present invention reduces local groundwater level construction method
Structural schematic diagram.

Specific embodiment
Referring to the drawings and embodiment the present invention will be described in detail:
Attached drawing 1-2 includes the following steps: it is found that a kind of local groundwater level construction method of self priming pump reduction
1) 2 are cheated close to catch pit side-walls setting casual water in 1 bottom of catch pit；
2) using large-sized rubble 3 filling casual water hole 2, the embedding pvc pipe 4 in rubble filling process；
3) it after the completion of 2 filling of casual water hole, is compacted using cement mortar, is levelling；When the waterproof layer 5 of catch pit 1 is constructed
Side is received at reserved pvc pipe 4；
4) self priming pump 6 is set at the top of catch pit 1,7 end of self-priming pump drain pipe is wrapped up fine and closely woven mesh filter screen, put in pre-buried
In pvc pipe 4；Water level is drawn water using self priming pump at any time in pvc pipe 4, discharges into gutter 8；
5) before underplate concrete pours, water level is reduced using self priming pump 6 first, before water level recovery, completes fusing
Pvc pipe 4 uses 10 closure construction operation of waterproof roll；
6) casting concrete 9 is quickly concentrated, is self-possessed by concrete 9 and guarantees that sealing part is tight.
The casual water is cheated 2 positions and is arranged other than 1 reinforcing bar orientation of catch pit.
4 diameter of pvc pipe is greater than the diameter of self-priming pump drain pipe 7, opens up inlet opening in pvc pipe side wall.
Self priming pump of the present invention reduces local groundwater level construction method, securely and reliably, improves construction efficiency, reduces worker
Labor intensity reduces construction cost, guarantees construction quality.
The above described is only a preferred embodiment of the present invention, not making in any form to structure of the invention
Limitation.Any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention,
Belong within the scope of technical solution of the present invention.
