Processes and process construction gravel gravel pile hammers: 1, machine in place: gravel pile drivers and vibratory hammer spring lift heavy pipes connected, close valve tip pile of soft foundation treatment price, aligning pile position; 2, vibration immersed tube: Start spring vibration hammer sink into the earth so immersed tube under the pressure of the spring shock vibration hammer strike force and hoist; 3, into the hole, filling gravel: the process of the immersed tube can hoist lifting hopper filling into the gravel; 4, pile extubation: immersed tube to the design requirements for depth, inner Gravel more than one-third of the tube length before extubation. Postextubation open gravel pile pile tip end, earlier extubation control vibration 10-15s after extubation, extubation edge vibration side where to buy soft-processing equipment, each pulling 1-1.5m to stop, and so forth when pile of gravel into the process can be fully compacted; 5, to be a pile after completion of construction, stone hammers next shift a pile of construction. Soft Rock Tunnel horizontal jet grouting methods: by controlling the first bracket and the second supporting frame synchronization of the movable body about a longitudinal axis to vary the spray boom of construction location, repeat steps ( 1) to (3) to obtain a plurality of first type drilling as well as a first-shaped stiffening member is inserted in a first type of the pile, so that adjacent portions of the first type of pile overlap in the radial direction, thereby said plurality of first type pile at least part of the edge of the tunnel to be formed to construct the first curtain system; (5), by controlling the first bracket and the second around the movable support frame synchronization the longitudinal axis of the fuselage rotated to change the position of the spray boom of construction, repeating steps (1) to (2) to further obtain a plurality of first type and a first type drilling underground culvert piles of soft foundation treatment, so adjacent to the first type of pile overlap in the radial direction, so that the plurality of first type pile at least part of the edge of the tunnel to be formed to construct the second curtain system, the first curtain system in conjunction with the second curtain system into a monolithic curtain system
