Abstract
There is the casing of opening the utility model discloses a kind of device for emergent precipitation of being constructed for basement foundation ditch, including bottom, the casing is provided with drainage gallery and slip casting passage.Using the utility model, cover occurring that water burst gushes sand ground point and indwelling drainage gallery reduces groundwater pressure on casing by casing, so as to during the secondary excavation in later stage, weaken adverse effect of the ground water pressure to substrate significantly.
Description
Technical field
The utility model is related to road construction field, and in particular to a kind of dress for emergent precipitation of being constructed for basement foundation ditch
Put.
Background technology
Substantial amounts of basement foundation ditch excavation construction is included in civil engineering, but during excavation of foundation pit, may be sent out
The husky situation of swelling swelling under the dried rhizome of rehmannia, for example, dash forward and meet high water head underground bearing water, fractured zones or foundation pit enclosure structure construction
Gap is excessive etc..At present under this urgent accident, traditional treatment method be by direct fill concrete or the earthwork come
Carry out back-pressure；Or the directly water filling into foundation ditch, to balance ground water pressure.
This traditional processing method fundamentally can not solve the problem of water burst gushes sand.For example, using concrete or
This method that husky point is backfilled is gushed in the earthwork to water burst, and water burst can be caused to gush husky point and be transferred to the weak part of other substrates,
Or foundation ditch is penetrated into by the hole between soil body particle.If using the method for water filling, follow-up excavation work band can be given
Carry out many inconvenience.
The main weak point of prior art processing method is listed below：
1st, handled due to carrying out the principle of balancing water pressure merely by the recovery original load in excavation face top, it is impossible to from root
Ground water pressure is cut down in sheet and applies the venture influence brought to follow-up foundation ditch；
2nd, it is necessary to put into the backfill operation that substantial amounts of human and material resources carry out true generous amount in processing procedure；Treat Chu Liwan
Secondary excavation is needed again after finishing, therefore adds construction investment amount；
3rd, backfill, reinforce, precipitation can not be carried out synchronously, the influence to construction speed is larger.
Utility model content
In view of the shortcomings of the prior art, the utility model is aimed to provide a kind of constructs emergent precipitation for basement foundation ditch
Device, realizes that more effective water burst gushes the processing of husky emergency case.
To achieve these goals, the utility model is adopted the following technical scheme that：
A kind of device for emergent precipitation of being constructed for basement foundation ditch, including bottom have the casing of opening, the casing
It is provided with drainage gallery and slip casting passage.
Further, the casing is communicated with three-way pipe ball valve as drainage gallery；In addition, the top of the casing is provided with
At least one set of pipeline with ball valve is used as drainage gallery and slip casting passage.
Further, the pipeline is mainly formed by connecting by more piece body by way of screw thread or buckle.
Further, the bottom margin of the casing is connected with skirtboard, and the skirtboard is main by sponge underlay and rubber face
Layer composition.
Further, the outside of the casing is provided with hanger.
Further, the bottom inside the casing is provided with filter screen.
The beneficial effects of the utility model are：
1st, sand ground point is gushed occurring water burst by the way that casing is covered, and indwelling drainage gallery reduces ground water pressure on casing
Power, so that during the secondary excavation in later stage, influence of the ground water pressure to base will weaken significantly；
2nd, because by drainage gallery, groundwater effect can progressively reduce in the pressure of substrate, can save backfill back-pressure
Side amount, so as to save a part of investment.It can in addition contain realize that backfill back-pressure, precipitation, reinforcing can be carried out synchronously, reduce pair
The influence of construction speed.
3rd, backfill back-pressure, precipitation, reinforcing can be carried out synchronously, reduce the influence to construction speed.
Brief description of the drawings
Fig. 1 is cross section structure schematic diagram of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model will be further described, it is necessary to which explanation, the present embodiment is with this skill
Premised on art scheme, detailed embodiment and specific operating process are given, but protection domain of the present utility model is not
It is limited to the present embodiment.
As shown in figure 1, a kind of device for emergent precipitation of being constructed for basement foundation ditch, including bottom have the casing of opening
1 (can use steel pile casting), the casing 1 is provided with drainage gallery and slip casting passage.
The method for carrying out the emergent precipitation of basement foundation ditch construction using described device is：
If 1) broke-out diseases gush husky phenomenon, described device is hung and covers substrate water burst and gushes husky position, and scheduling job people
Member gushes husky region fill concrete or the earthwork to carry out back-pressure around casing to water burst；
2) sluiced by drainage gallery, drainage gallery is connected to extension pipeline, led to water pair by water pump
Engineering devoid of risk position；
3) while water-pumping/draining, carry out slip casting around foundation ditch and at substrate position, reinforce；
4) after treating that ground water pressure is stable, slip casting closure is carried out by slip casting passage.
Further, the casing 1 is communicated with three-way pipe ball valve 2 as drainage gallery；In addition, the top of the casing 1
Provided with least one set, the pipeline 3 with ball valve 32 is used as drainage gallery and slip casting passage.
When in use, by three-way pipe ball valve connection extension pipeline, the extension pipeline is connected to water pump, is starting to sluice
When, open three-way pipe ball valve and export to water to engineering devoid of risk position through extension pipeline by water pump.It is described with ball valve
Pipeline can both make drainage gallery, can also be used as slip casting passage.When water is larger, three-way pipe ball valve, which sluices, can not meet requirement
When, can the ball valves of opening conduits together sluiced using the pipeline.Multigroup pipeline can be set, according to reality when specifically used
Need to determine that opening a how many group pipelines is together sluiced.It is to be seen to arrive after ground water pressure stabilization, then entered by the pipeline
Row slip casting is blocked.
Further, the pipeline 3 is mainly formed by connecting by more piece body 31 by way of screw thread or buckle.It is described
Pipeline can be according to head size spreading.
Further, the bottom margin of the casing 1 is connected with skirtboard 4, and the skirtboard 4 is main by sponge underlay 42 and rubber
Glue surface layer 41 is constituted.Foundation ditch is usually out-of-flatness, by soft and skirtboard that flexible sponge and rubber constitutes contributes to
Stable and sealing steel cylinder, ballast is on skirtboard when fill concrete or the earthwork.
Further, the outside of the casing 1 is provided with hanger 5.The setting of hanger can facilitate the lifting of described device.
Further, the bottom inside the casing 1 is provided with filter screen 6.The filter screen can use close mesh Steel net, mainly
For filtering the debris such as the sandstone in the water released, drainage gallery can be avoided to block, while avoiding soil particle from outflowing with water generation
Stratum Loss, causes surrounding formations to sink.The filter screen should be adjusted according to geological condition, in this way the less fine sand of particle
Layer, should select the less filter screen of mesh number.The larger stratum of particle, the filter screen that mesh number should be selected larger in this way.
For those skilled in the art, technical scheme that can be more than and design, make various corresponding
Change and deform, and all these change and deformation should be construed as being included in the utility model scope of the claims it
It is interior.
