3) cover to reinforcement that MJS location proximates are cut with pneumatic pick, exposes diaphragm wall reinforcing bar, by double cabin self-closings hole
The front deck of sealer for mouth is welded on exposed diaphragm wall reinforcing bar；
4) the gate valve part installed on front deck is opened for the second time after passing through gate valve part and front hatch sections with water drilling
Diaphragm wall is broken completely and is worn by hole, exits water drilling, and gate valve cuts off front deck and MJS leveling peg active well after being partially in closed state
Between connection；
5) the installing pipe mouthparts on gate valve part, nozzle device partial interior are disposed at least two seals rubber ring；
6) solid grease is partially filled with toward front deck and nozzle device respectively；
7) it first allows the horizontal drilling rod of MJS to enter pipe mouthparts, is then turned on gate valve part, the horizontal drilling rod of MJS is gone successively to
Behind gate valve part and front deck, diaphragm wall is passed through, the horizontal drilling rod of MJS enters the soil body and constructs.
As a further improvement of the above technical scheme, in step 2, using diameter is the water drilling of 200mm against MJS
Stake site carries out first time aperture, and first time aperture depth is 550 ~ 650mm, and the direction of first time aperture is along horizontal direction.
As a further improvement of the above technical scheme, in step 4), diameter is used to carry out second for the water drilling of 200mm
Diaphragm wall is got through after secondary aperture, exits water drilling, closing gate valve part.
As a further improvement of the above technical scheme, in step 5), the sealing rubber ring internal diameter is 80mm, sealing
Rubber ring with a thickness of 12mm, pipe mouthparts are separated into several cavitys by sealing rubber ring.
As a further improvement of the above technical scheme, in step 6), turn off the pressure reducing valve of front deck, open the note of front deck
Hole is starched, solid grease is filled toward front deck by injected hole；It is filled in pipe mouthparts by the open end of pipe mouthparts full
Solid grease.
As a further improvement of the above technical scheme, in step 7), diameter is that the horizontal drilling rod of MJS of 142mm passes through
After the sealing rubber ring of internal diameter 80mm in pipe mouthparts, gate valve part and front deck, diaphragm wall, the horizontal drilling rod edge MJS are passed through
Horizontal direction enter the soil body and construct.
The beneficial effects of the present invention are: the present invention uses internal diameter by injecting solid grease in front deck and pipe mouthparts
The horizontal drilling rod of the MJS of diameter 142mm is sealed by the sealing rubber ring of 80mm, makes the horizontal drilling rod of MJS is closed to pass through diaphragm wall
Into the soil body, avoid that the horizontal drilling rod of MJS is directly broken to be worn diaphragm wall and lead to water burst, gush the case where sand.In addition, the horizontal drilling rod of MJS
Into the state for being always maintained at sealing in soil body work progress, soil erosion on the outside of foundation pit is avoided, ground can be controlled well
Sedimentation.
