Abstract
The utility model relates to a treatment structure for building foundation pits, in particular to a shut-in dewatering device for a tube well and solves the problem that drainage of the existing foundation well is high in cost, difficult in construction, low in efficiency and poor in effect. The dewatering device structurally comprises a motor-pumped well, a plastic pipe disposed in the motor-pumped well and is communicated with a self-priming pump which is connected with a reservoir, a lower layer in the pumping well is provided with a fine stone layer, and an upper layer in the pumping well is a concrete layer. The shut-in dewatering device is used for drainage, so that cost is low, construction is simple, operation period is shortened, performance of foundation and foundation water proofing are improved, and construction is convenient.
Description
Technical field
The utility model relates to a kind of building foundation pit and processes structure, is specially a kind of pipe well shut-in well dewatering device.
Background technology
In building operations, the water in the foundation ditch needs in time to get rid of to guarantee construction quality.As schematically shown in Figure 1, existing water discharge method is exactly that a submersible pump is installed under pipe well simply, then drawing water to have problems is, the foundation dewatering well point should be arranged on foundation ditch both sides or on every side, but Party A or construction party are arranged on foundation ditch inside with well in a lot of engineering.1, buries the motor-pumped well of foundation ditch inside underground, and again around foundation ditch, the well point is set, carry out precipitation.But the expense that the method produces is larger, needs to drop into a large amount of manpower and materials, improves engineering cost, also affects programming.2, reserved opening on basic raft plate, construction period is proceeded precipitation on raft plate top.But the method construction trouble, the processing of later stage reserving hole, the stickup of waterproof bother more, and can't guarantee the globality of waterproofing course, basic waterproof do not guarantee, and the later stage indoor can not be the fastest carry out backfill, affect the duration.
Summary of the invention
The utility model is high in order to solve the expense that exists in the existing basic well array water, constructional difficulties, and efficient is low, the problem of weak effect, and a kind of pipe well shut-in well dewatering device is provided.
The technical solution of the utility model is, a kind of pipe well shut-in well dewatering device, and structure comprises motor-pumped well, is arranged on the plastic pipe in the motor-pumped well, and plastic pipe is communicated with self priming pump, and self priming pump connects reservoir, and lower floor prevents the microlith layer in the motor-pumped well, the upper strata is layer of concrete.The part below 2/3 of the plastic pipe length in the described motor-pumped well is provided with some borings, the outer filter screen that is provided with of boring.
Structure described in the utility model need to be buried underground the precipitation motor-pumped well when laying basic hardcore bed in when construction, buried plastic pipe underground simultaneously in hoistway, and it is outside to make it to stretch out from hardcore bed inside the basis, and uses self priming pump to proceed precipitation.Compare with existing dewatering measure, the problem that affects construction speed that this practicality has avoided motor-pumped well directly to draw water and bring with water pump is directly shunt in a well, and has avoided again destroying the problem of integral waterproofing layer.Thereby, adopting this structure precipitation of the utility model, expense is lower, and construction is simple, the overall performance of reduction of erection time, raising basis and basic waterproof, and easy construction.
Description of drawings
Fig. 1 is the structural representation of existing apparatus
Fig. 2 is structural representation of the present utility model
Fig. 3 is the interior part-structure schematic diagram of the motor-pumped well of plastic pipe
Among the figure: 1-submersible pump, 2-underground water, 3-basal layer, 4-reservoir, 5-self priming pump, 6-layer of concrete, 7-microlith layer, 8-plastic pipe.
The specific embodiment
As schematically shown in Figure 2, a kind of pipe well shut-in well dewatering device, structure comprises motor-pumped well, is arranged on the plastic pipe 8 in the motor-pumped well, and plastic pipe 8 is communicated with self priming pump 5, and self priming pump 5 connects reservoir 4, and microlith layer 7 is placed by lower floor in the motor-pumped well, and the upper strata is layer of concrete 6.
As schematically shown in Figure 3, the part below 2/3 of plastic pipe 8 length in the described motor-pumped well is provided with some borings, the outer filter screen that is provided with of boring.
The plastic pipe that stretches into well inside is shut bottom, and the evenly boring (aperture is less than the particle diameter of used microlith, and the hole situation is seen Fig. 3) below 2/3 of the plastic pipe length in well, wrap up with filter screen again.Then the inner perfusion of motor-pumped well particle diameter is the microlith of 5.0mm, and vibration compacting forms the microlith layer.Build with the C15 pea gravel concreten at one meter of distance well head, form layer of concrete with the vibrating head vibration compacting.
The sealing of plastic pipe is the key that determines these patent success or failure, so will carefully check the sealing of plastic pipe, guarantees that self priming pump can work according to re-set target.Make at last groundwater level below the construction working face, guarantee that part is positioned at below the water surface all the time under the plastic pipe, satisfy the construction needs.
