Abstract
The present invention relates to Deep Foundation Pit Supporting Project, particularly relate to the water-stopping method of deep foundation pit support.Drain water-stopping method between a kind of Punching Borehole Cast-in-place Concrete Pile campshed support pile, it includes: in Excavation Process, before extension bar-mat reinforcement spray sets facing concrete, collection arm is embedded between bored concrete pile, it is connected with standpipe by joint, along with the excavation of foundation pit degree of depth connects downwards, finally bottom foundation ditch, guide to cheat end collecting main through facing concrete, after unified collection, use water pump to be discharged to outside foundation ditch.The present invention can realize sealing without water-stop curtain, reduces construction cost and cycle.
Description
Technical field
The present invention relates to Deep Foundation Pit Supporting Project, particularly relate to the water-stopping method of deep foundation pit support.
Background technology
Deep Foundation Pit Supporting Project, through the campshed support pattern frequently with bored concrete pile form, uses high pressure outstanding spray stake between campshed
Carry out waterproof between piles.But at some deep & thick silt regions or the sludge region of fill block stone throwing or when having into rock demand, frequently with
Punching Borehole Cast-in-place Concrete Pile technique is constructed, and Punching Borehole Cast-in-place Concrete Pile easily causes the phenomenon such as collapse hole, reaming, causes waterproof between piles curtain to be difficult to
Implement, need to use change fill out or draw hole after carry out mixing pile or high-pressure rotary jet grouting pile water-stopping method, such construction cost is high, long in time limit,
Excavation Process also needs to secondary sealing, affects construction operation.
Summary of the invention
Present invention seek to address that drawbacks described above, it is provided that drain water-stopping method between a kind of Punching Borehole Cast-in-place Concrete Pile campshed support pile.This
Invent and can realize sealing without water-stop curtain, reduce construction cost and cycle.
For solving the problems referred to above, drain water-stopping method between a kind of Punching Borehole Cast-in-place Concrete Pile campshed support pile, it includes: open at foundation ditch
During digging, before extension bar-mat reinforcement spray sets facing concrete, collection arm is embedded between bored concrete pile, by joint with standpipe even
Connect, along with the excavation of foundation pit degree of depth connects downwards, finally guide to cheat end collecting main through facing concrete bottom foundation ditch,
Water pump is used to be discharged to outside foundation ditch after unified collection.
Drain water-stopping method between described Punching Borehole Cast-in-place Concrete Pile campshed support pile, it is characterised in that described collection branch pipe wall
It is provided with collection hole, body parcel filter membrane, and is bundled fixing by rope or iron wire.
Present invention process is simple, strong operability, simple installation.Reduce the engineering cost of water-stop curtain, effectively improve
Working environment in foundation ditch, it is ensured that deep pit monitor, improves work efficiency, has higher using value.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is schematic diagram of the present invention；
Fig. 2 is elevation of the present invention；
Fig. 3 is described arm schematic diagram.
Detailed description of the invention
Please see Figure 1 and Fig. 2, drain water-stopping method between one Punching Borehole Cast-in-place Concrete Pile campshed support pile of the present invention, it includes: at base
In the digging process of hole, before extension bar-mat reinforcement spray sets facing concrete 8, the collection arm 1 of this drainage system is embedded in bored concrete pile 5
Between, it is connected with standpipe 3 by joint 2, along with the excavation of foundation pit degree of depth connects downwards, finally mixes through mask bottom foundation ditch
Solidifying soil guides to cheat end collecting main 4, uses the catch pit 9 that water pump is discharged in foundation ditch after unified collection.
Drain water-stopping method between described Punching Borehole Cast-in-place Concrete Pile campshed support pile, described collection branch pipe wall is provided with collection hole
10, body parcel filter membrane 6, and bundled fixing (seeing Fig. 3) by rope or iron wire 7.
Embodiment:
Collecting arm 1 uses the pvc of φ 32 to manage, and tube wall is provided with the filter membranes 6 such as the collection hole of φ 5, body parcel geotextiles, adopts
It is fixed colligation with nylon rope or iron wire 7.
Punching Borehole Cast-in-place Concrete Pile campshed has been implemented, and before excavation of foundation pit, buries collection arm 1 underground, use PVC reducing between drilled pile
Joint 2 is connected with φ 50PVC standpipe 3, along with the degree of depth of excavation of foundation pit, by the collecting main 4 of 0.5m-0.75m segmentation Yu φ 75
Connect, collect the infiltration between campshed, by arranging catch pit water pump in excavation face, water is discharged to outside foundation ditch, it is ensured that opening of foundation ditch
Dig environment.
Every section bury underground after arm and riser, along with the intensification of cutting depth, use linked network spray between stake to set concrete and enter
Row is fixing.
Collecting arm, standpipe and the diameter of collecting main and material can different according to the water yield between campshed from stake vertical
Straight degree, selects different diameters and material to make.
Claims (2)
1. drain water-stopping method between a Punching Borehole Cast-in-place Concrete Pile campshed support pile, it is characterised in that it uses to include collection
