A kind of waterproof foundation pit
Technical field
The utility model relates to Construction Technology fields, and in particular to a kind of waterproof foundation pit.
Background technique
Foundation pit belongs to temporary work, refers on the position of basic engineering according to substrate absolute altitude and basic plane size institute
The heatable adobe sleeping platform of excavation, the effect of foundation pit are to provide a space, and enable basis builds the operation position specified according to design
It carries out.However in traditional foundation pit use process, need to prevent the infiltration of underground water or ground rainwater, otherwise can make to be excavated
Ground around foundation pit is unstable, produces bigger effect to the safe handling of foundation pit.
A kind of band of patent is conducive to the pattern foundation pit supporting structure (application No. is 201720031646.5) of discharge structure, passes through drainpipe
Design, slope surface infiltration directly export is able to carry out simple filtering, prevented and by the way that rubble is arranged on the outside of aqueduct
Silt is flowed out from diversion pipe, but structure is complicated for pattern foundation pit supporting structure plate, and the fixed function of higher cost, pattern foundation pit supporting structure plate is limited,
And drainpipe stability in drainage trap is insufficient.
The infiltration that therefore, it is necessary to a kind of structures simply, can effectively be discharged in foundation pit aquitard soil, and high stability
Waterproof foundation pit.
Utility model content
The purpose of this utility model is the deficiency for traditional foundation pit, provides one kind and is provided with that structure is simple, can effectively arrange
Infiltration in foundation pit aquitard soil out, and the waterproof foundation pit that stability is high.
The utility model provides following technical solution:
A kind of waterproof foundation pit, including retaining-plate, drainage cage and drainpipe, the retaining-plate are mounted on the outside of aquitard soil
And the retaining-plate is equipped with the through-hole for installing the drainpipe, the drainage cage is mounted in aquitard soil, the draining
Pipe is mounted in the drainage cage, and the drainpipe tilts down and pass through the through-hole, the drainage cage and the drainpipe
Between be filled with filtrate, the drainpipe is placed in the part in the drainage cage equipped with several water seepage holes, and the water seepage hole is connected with
The arc block plate of protrusion, the retaining-plate outside are equipped with supporting network, and the drainpipe is fixed on the supporting network by fixing clamp.
Preferably, the drainage cage is equipped with several filtration holes, and the material that the drainage cage uses is plastics or timber.
Preferably, the filtrate is rubble or plastic filler, and the filter effect of rubble and plastics is good and cheap.
Preferably, the drainpipe be located at the nozzle in the drainage cage be equipped with strainer, be in order to prevent silt etc. into
Enter into drainpipe.
Preferably, the supporting network is that several lateral iron wires connect with several longitudinal iron wire alternating orthogonals and formed netted
Structure, the supporting network play the role of further fixing aquitard soil, also play fixed drainpipe.
Preferably, hook of the fixing clamp by support frame and set on support frame two sides forms, and plays the drainpipe
The effect being fixed on the supporting network.
The beneficial effects of the utility model are:
(1) the utility model exports the infiltration in the aquitard soil of foundation pit by drainpipe, and by drainage cage
Strainer at filtrate and drain pipe port is simply filtered, and prevents a large amount of silts from entering drainpipe.In addition, compared to general
Round water seepage hole, the water seepage hole of the utility model are connected with the arc block plate of protrusion, not only facilitate the infiltration for reducing silt etc.,
Also preferably drainpipe can be fixed in drainage cage simultaneously.
(2) the utility model is fixed the aquitard soil of foundation pit in such a way that retaining-plate is in conjunction with supporting network,
It is beneficial to prevent the deformation or collapsing of foundation pit, in addition, drainpipe is fixed on supporting network by the utility model by fixing clamp, into
One step improves the stability of drainpipe, it helps further fixes to aquitard soil.

Specific embodiment
As shown in Figure 1 to Figure 3, a kind of waterproof foundation pit, including retaining-plate 1, drainage cage 3 and drainpipe 5, retaining-plate 1 are installed
The through-hole for installing drainpipe 5 is equipped on 2 outside of aquitard soil and retaining-plate 1, drainage cage 3 is mounted on aquitard soil
In 2, drainage cage 3 is equipped with several filtration holes, and the material that drainage cage 3 uses is plastics or timber.Drainpipe 5 is mounted on drainage cage
In 3, drainpipe 5 tilts down and passes through the through-hole on retaining-plate 1, and filled with filtrate 4 between drainage cage 3 and drainpipe 5, filtrate 4 is
Rubble or plastic filler, because the filter effect of rubble and plastics is good, and cheap, drainpipe 5 is located at the pipe in drainage cage 3
Strainer 8 is equipped at mouthful, drainpipe 5 is placed in the part in aquitard soil 2 equipped with several water seepage holes 6, and water seepage hole 6 is connected with protrusion
Arc block plate 7, be equipped with supporting network 9 on the outside of retaining-plate 1, it is vertical that supporting network 9 is that several lateral iron wires replace with several longitudinal iron wires
Direct-connected connect and the reticular structure formed, drainpipe 5 are fixed on supporting network 9 by fixing clamp 10, and fixing clamp 10 is by support frame 11
And the hook 12 set on 11 two sides of support frame forms.
The advantage of the utility model are as follows: drainpipe 5 can effectively export the infiltration in the aquitard soil 2 of foundation pit, and drainage
The strainer 8 at 5 nozzle of filtrate 4 and drainpipe in cage 3 can simply filter infiltration;Water seepage hole 6 is connected with protrusion
Arc block plate 7 not only facilitates the infiltration for reducing silt etc., and facilitates drainpipe 5 and be fixed in drainage cage 3;Retaining-plate 1 with
The mode that supporting network 9 combines can the aquitard soil 2 preferably to foundation pit be fixed, and the setting of fixing clamp 10 is not only into one
Step improves the stability of drainpipe 5, it helps to further fixing for aquitard soil 2.
The foregoing is merely the preferred application cases of the utility model, are not intended to limit the utility model, although reference
