Abstract
The invention discloses a method for processing underground support structure leakage of a foundation with a rock block layer in soft soil. The method includes the steps: 1) removing a soil body between two adjacent reinforced concrete filling piles; and 2) constructing a water-sealing brick wall between the two adjacent reinforced concrete filling piles, and embedding drainage pipelines under an underground structure concrete cushion layer. A drainage pipe is embedded in the water-sealing brick wall, a water inlet of the drainage pipe is arranged on the water-seepage concentrated portion in a soil body outside the water-sealing brick wall, a water outlet of the drainage pipe is connected with a water discharging pipeline through a connection pipeline, the water discharging pipe is connected with a water collecting well in a foundation pit to form a water discharging system, and the brick wall is plastered by cement mortar. The method is easy and convenient to implement, high in efficiency, capable of performing construction quality control conveniently, safe and reliable, remarkably reduces construction cost, improves working efficiency, saves labor, materials and financial resources, and is suitable for construction environments of a foundation with the rock block layer in the soft soil, areas resourceful in underground water and the like.
Description
Technical field
The present invention relates to a kind of underground support fabric drain method for treating water, particularly relate to block stone layer ground underground support fabric drain method for treating water is arranged in a kind of weak soil.
Background technology
General deep foundation pit supporting structure adopts the deposited reinforced concrete pile rotary churning pile waterproof of man that adds high pressure, and the hole phenomenon of in soft foundation deposited reinforced concrete pile pore forming process, collapsing is very general, and fullness coefficient increases; High-pressure rotary jet grouting pile as sealing between two deposited reinforced concrete piles can't be constructed equally.The mucky soil layer thickness is darker in the coastal area, and the block stone layer buried depth is big, considers from construction technology and engineering cost two aspects, needs to explore the underground support fabric drain method for treating water that makes new advances.
Summary of the invention
The present invention provides in a kind of weak soil of being convenient to the Control Engineering quality block stone layer ground underground support fabric drain method for treating water is arranged for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: block stone layer ground underground support fabric drain method for treating water is arranged in a kind of weak soil; Said underground support structure comprises many deposited reinforced concrete piles arranged side by side, and this processing method of leaking may further comprise the steps:
One) soil body between two adjacent deposited reinforced concrete piles is removed;
Two) construction sealing brick wall between two adjacent deposited reinforced concrete piles is buried drainage pipe underground below the underground structure concrete cushion;
Be embedded with drainage tube in the said sealing brick wall; The water inlet of said drainage tube is positioned at the position that the outer soil body infiltration of sealing brick wall is concentrated; The delivery port of said drainage tube is connected with drainage pipe through connecting pipeline, and said drainage pipe is connected with the interior collecting well of foundation ditch, forms drainage system; Said brick wall is used cement sand plaster.
Advantage and good effect that the present invention has are: 1) reduced the high-pressure rotary-spray pile water stopping curtain, speed of application is fast; 2) with brick wall shutoff inter-pile soil, construction is simple, and the drainage drainage effect is good; 3) below the underground structure concrete cushion, bury drainage pipe underground, do not take the works space, practice thrift the supporting and protection structure investment; Construction environments such as 4) the present invention is applicable to has the block stone layer ground in the weak soil, the more rich area of underground water; 5) the present invention is simple and easy to do, efficient is high, be convenient to Control Engineering quality, safe and reliable, has reduced construction cost to a great extent, has improved operating efficiency, has saved human and material resources and financial resources.

For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1～Fig. 4, block stone layer ground underground support fabric drain method for treating water is arranged in a kind of weak soil, said underground support structure comprises many deposited reinforced concrete piles arranged side by side 1, and the above-mentioned processing method of leaking may further comprise the steps:
One) soil body between two adjacent deposited reinforced concrete piles 1 is removed;
Two) construction sealing brick wall 2 between two adjacent deposited reinforced concrete piles 1 is buried drainage pipe 6 underground below underground structure concrete cushion 5;
Be embedded with drainage tube 3 in the said sealing brick wall 2; The water inlet of said drainage tube 3 is positioned at the position that the 2 outer soil body infiltrations of sealing brick wall are concentrated; The delivery port of said drainage tube 3 is connected with drainage pipe 6 through connecting pipeline 9, and said drainage pipe 6 is connected with the interior collecting well 7 of foundation ditch, forms drainage system.With submersible pump 8 water in the collecting well is discharged to surface drainage system; Said brick wall 2 usefulness cement mortar 4 are wiped one's face, and prevent infiltration.
In the present embodiment, brick wall 2 adopts MU10 brick and M7.5 cement mortar; It is the pvc pipe of 50mm that drainage tube adopts caliber; Brick wall is wiped one's face and is adopted the 1:2 cement mortar; It is the pvc pipe of 90mm that drainage pipe adopts caliber; Connecting pipeline employing caliber is the hard PVC pipe of 50mm; The wide 2m of collecting well, dark 1.5m, spacing 60m is provided with one, is discharged to surface drainage system with the 200QJ63-24/2 submersible pump.
Although combine accompanying drawing that the preferred embodiments of the present invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
