Segmentation carries out high-pressure slip-casting, and formation pours building body, pours building body and be connected with original water-stop curtain stake.
By using above-mentioned technical proposal, slope protection pile and sealing curtain can fully be made up by pouring building body and being connected with water-stop curtain
Gap between curtain stake, reaches good sealing plugging effect.
Preferably, water-stop curtain stake is one kind in rotary churning pile, mixing pile or spray mixing pile.
By using above-mentioned technical proposal, between stake between center or stake on the outside of axis certain position construction rotary churning pile, stir spray
Stake, mixing pile etc. formed water-stop curtain, have vibration equipment is small, noise is small, on close to buildings influence it is small, construction speed is fast,
The advantages that low cost.
Preferably, the surveying setting-out uses GPS, total powerstation or transit survey.
By using above-mentioned technical proposal, measurement can be made accurate by GPS, total powerstation or transit survey, avoid measuring
Error causes construction error, influences construction effect.
In conclusion the invention has the advantages that：
1, the application of waterproof between piles curtain combination stake side sleeve valve barrel grouting water stop construction method solves construction one between slope protection pile
Water-stop curtain stake and universal percolating water problem caused by slope protection pile faying face weakness or perpendicularity deviation, improve waterproof between piles curtain
Reliability, and relatively double curtain pile scheme has saved construction cost, shortens construction period, more economical, environmentally friendly；
2, mini-valve tube material is cheap, is transferred together with steel reinforcement cage and avoids repeating pore-forming, has saved construction cost, shortens construction week
Phase, good environmental protection, and avoid the construction error generated when the secondary pore-forming of mini-valve tube；
3, in the larger boulder bed of grain size, in the specific soil layer such as the big clay of pile penetration or powder soil horizon, rotary churning pile is susceptible to contracting
The phenomenon that neck, using mini-valve tube to being segmented high-pressure slip-casting in specific soil layer, to soil-cement body at original water-stop curtain stake occlusion
It reinforced, block gap and be engaged bad position, improve the water blocking quality of waterproof between piles curtain pile；
4, simple for process using stake side sleeve valve barrel grouting combination waterproof between piles curtain pile technique half sleeve valve pipe construction, it is efficient, it makes
Valence is at low cost, wide application, is the strong supplement of " a water-seal pile scheme of constructing between slope protection pile "；
5, using symmetrically being bound on the outside of steel reinforcement cage, two sleeve valve barrel grouting device success rates are high, positioning is simple.

Direction.
, there is shield in the waterproof curtain construction method that a water-stop curtain stake 2 of constructing between slope protection pile 1 is combined with slope protection pile 1
The case where slope stake 1 and water-stop curtain stake 2 contact surface be weak or perpendicularity deviation, be easy to cause water-stop curtain stake 2 and slope protection pile 1 it
Between formed leakage, to solve the above problems, the present invention 12 slip casting construction method of mini-valve tube is fully applied to fill up water-stop curtain stake 2 with
The gap of 1 link position of slope protection pile and the part of contact surface weakness.
12 slip casting construction method of mini-valve tube is pioneering in the eighties of last century 5O ages by French Soletanche foundation engineerings company
A kind of slip casting construction method.12 slip casting construction method of mini-valve tube can carry out repeating note due to can preferably control range of grouting and grouting pressure
Slurry, and the features such as the possibility very little of generation grout and grout leaking, it is known as one of most reliable slip casting construction method both at home and abroad.
12 structure of mini-valve tube is mainly made of Ф 52mmPVC outer tubes, 6 points of zinc-plated slip casting inner tubes, rubber case, sealing rings etc..
There is special requirement that Ф 50mm welded still pipes can also be used as outer tube.Mini-valve tube 12 be one kind can only to outside pipe pulp, Bu Nengxiang
The unidirectional closing device of slurry is returned in pipe.
The concrete construction method of the present embodiment is illustrated below：
A kind of waterproof between piles curtain combination stake side sleeve valve barrel grouting water stop construction method, includes the following steps：
Step a, it determines 1 position of slope protection pile by using GPS, total powerstation or transit survey and marks, determine water-stop curtain stake 2
Stake position simultaneously marks, and both slope protection pile 1 and water-stop curtain stake 2 are alternately arranged, and stake diameter can be different；
Step b, the stake position set according to survey forms 1 hole of slope protection pile using mud off wet construction pore-forming or dry operation.Mud protects
Rotary drilling rig, clean-out machine or percussive drill etc. can be selected in wall wet construction pore-forming drill；Long spire can be selected in dry operation pore-forming
11 technique of steel reinforcement cage is planted after being pumped concrete in drilling machine pore-forming center；
Step c, two 12 grouting devices of mini-valve tube are symmetrically bound according to sealing depth requirements and along the length direction of steel reinforcement cage 11
On 11 outer side center line of steel reinforcement cage, hangs in the steel reinforcement cage 11 with mini-valve tube 12 to 1 hole of slope protection pile of both sides, let off under steel reinforcement cage 11
The direction that 12 grouting device of mini-valve tube is controlled in journey ensures 12 central point of mini-valve tube on the line at 1 center of slope protection pile；
Step d, concrete perfusion forms slope protection pile 1, and carries out the pile body maintenance of slope protection pile 1；
Step e, water-stop curtain between construction stake, forms water-stop curtain stake 2, and water-stop curtain stake 2 is rotary churning pile, mixing pile or spray mixing pile
In one kind；
Step f, 1 both sides mini-valve tube of slope protection pile, 12 slip casting, which blocks, reinforces, and is segmented in water-bearing layer into horizontal high voltage using mini-valve tube 12
Slip casting, formation pour building body 3, pour building body 3 and be connected with original water-stop curtain stake 2,12 slip casting of mini-valve tube should be in bank protection
It is carried out in stake 1 pile body maintenance 12h-72h, and completes to carry out in for 24 hours in the construction of water-stop curtain stake 2；
Step g, water-stop curtain stake 2 conserves.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, people in the art
Member can as needed make the present embodiment the modification of not creative contribution after reading this specification, but as long as at this
It is all protected by Patent Law in the right of invention.
