The drill bit structure driven using drilling rod bottom setting hydraulic motor, is carried out the construction of ultra-thin water-stop curtain with ribbing, can saved
Cement slurry increases the rigidity of water-stop curtain, reduces construction joint, effectively improves the construction quality of water-stop curtain, short time limit, into one
Step lowers engineering cost, improves Business Economic Benefit.
The object of the present invention is achieved like this: a kind of ultra-thin water stop curtain structure with ribbing, its main feature is that the water-stop curtain
It is made of the seepproof screen of several width setting fin, adjacent seepproof screen is integrally formed the ultra-thin sealing with ribbing of structure using overlap joint
Curtain, overlapping part length are determined that the fin is arranged in parallel in single width seepproof screen by water-stop curtain depth and verticality
Portion, and be the semicircle cylinder of protrusion metope.
A kind of construction method of ultra-thin water stop curtain structure with ribbing, its main feature is that using the vertically disposed rotation in drilling rod bottom
Drill bit is sprayed, carries out the ultra-thin water-stop curtain construction with rib structure in the steps below:
(1) construction of pilot hole
Choose whether to follow up using casing using drilling machine pilot hole to projected depth, and according to soil property situation, the pilot hole it is ensured that
The placement of drill bit and drilling rod determines the diameter of drill bit according to water-stop curtain thickness；The drill bit is by end tooth
Wheel is engaged with the output gear of hydraulic motor；The whirl spraying pipe is vertical connect with whirl spraying pipe by right-angle elbow pipe；The hydraulic horse
It is driven up to the oil line pipe by connecting, drill bit rotation is driven by the end gear that output gear engages, and by being arranged in
Several spouts in drill bit carry out the jet mixing perpendicular to drilling rod to the soil body.
(2) host is in place
Lowering drill pipes and drill bit in pilot hole, and other drilling rods are docked, guarantee leakproofness, until pre- depthkeeping of the decentralization to pilot hole
Degree.
(3) construction of single width seepproof screen
After drilling rod is in place, each technological parameter is determined, then open mud valve and carry out spoil disposal, drilling rod promotes whitewashing after spoil disposal, hangs down
Directly carry out rotation whitewashing in the drill bit of drilling rod, as used casing when pilot hole, then every time need to by after one section of sleeve lift again
It whitewashes, one section of the every promotion of drilling rod need to be dismantled, and up to construction to top mark height, complete stopping for the first width growth fin
Waterwall.
(4) construction of all seepproof screens
Above-mentioned (one) ~ (three) step is repeated, is sequentially completed the seepproof screen of the second width setting fin, stopping for fin is arranged in third width
Waterwall ... until all seepproof screen constructions finish, and determines that adjacent seepproof screen overlaps according to water-stop curtain depth and verticality
The length at position.
The present invention has structure simple compared with prior art, and water-stop curtain is equal thickness seepproof screen, and cement slurry obtains
It makes full use of, water-stop curtain is protruded in pilot hole part, therefore the water-stop curtain is seepproof screen with ribbing, can increase the rigid of water-stop curtain
Degree, construction drill can adjust the length of single width water-stop curtain according to pressure size, reduce lap joint, effectively improve water-stop curtain
Construction quality, short time limit further lowers engineering cost, improves Business Economic Benefit.

Specific embodiment
Refering to 1 ~ Fig. 2 of attached drawing, the present invention is made of the seepproof screen 12 of several width setting fin 11, and adjacent seepproof screen 12 is adopted
With overlap joint, it is integrally formed the ultra-thin water-stop curtain 16 with ribbing of structure, 13 length of overlapping part is by water-stop curtain depth and vertically
Degree determines that the fin 11 is arranged in parallel in 12 middle part of single width seepproof screen, and is the semicircle cylinder of protrusion metope.
Refering to 1 ~ Fig. 3 of attached drawing, the present invention uses the vertically disposed drill bit 2 in 1 bottom of drilling rod, carries out in the steps below
The construction of ultra-thin water-stop curtain with ribbing 16:
(1) construction of pilot hole
Choose whether to follow up using casing using drilling machine pilot hole to projected depth, and according to soil property situation, the pilot hole it is ensured that
The placement of drill bit 2 and drilling rod 1 determines the diameter of drill bit 2 according to the thickness of ultra-thin water-stop curtain 16 with ribbing.
Refering to attached drawing 3, the drill bit 2 is engaged by end gear 21 with the output gear 41 of hydraulic motor 4；The rotation
Jet pipe 5 is vertical connect with whirl spraying pipe 5 by right-angle elbow pipe 51；The hydraulic motor 4 is driven by the oil line pipe 42 connected, is passed through
The end gear 21 that output gear 41 engages drives drill bit 2 to rotate, and several spouts 22 by being arranged in drill bit 2
Jet mixing perpendicular to drilling rod 1 is carried out to the soil body.
(2) host is in place
