The specific embodiment
Shown in Fig. 1-2, the described a kind of overlength pipe jacking anti-drag slurry minute storehouse filling mechanism of the utility model embodiment, comprise pipe curtain steel pipe 1, the front end of described pipe curtain steel pipe 1 is connected with development machine 3 by correction articulated mounting 2, the front end of development machine 3 is equipped with cutterhead 4, be connected with on the cutterhead 4 into muddy water pipe 5 and mud extraction water pipe 6, the other end that advances muddy water pipe 5 and mud extraction water pipe 6 all passes the outside that pipe curtain steel pipe 1 extends to pipe curtain steel pipe 1 rear end, the rear end of described pipe curtain steel pipe 1 is equipped with jack top pick 7, jack top pick 7 is fixedly connected with by the rear parados 9 of distribution beam 8 with the outside, the top middle portion of described pipe curtain steel pipe 1 is provided with the first injected hole 10 near pipe curtain steel pipe 1 front end 2.5m place, the 0.05m place, front side of the first injected hole 10 is provided with first minute storehouse and cuts off ring 11, the rear side of the first injected hole 10 5m place, every interval and 30m place, every interval are provided with respectively the second injected hole 12 and second minute storehouse cuts off ring 13, described the first injected hole 10 and the second injected hole 12 all are connected with the notes lubricated slurry pipe 14 that is installed in pipe curtain steel pipe 1 inside, and 3m place, every interval is provided with snap joint 15 in the steel pipe on the described notes lubricated slurry pipe 14.
Describedly advance muddy water pipe 5 and mud extraction water pipe 6 respectively by advancing the muddy water pump and the spoil disposal water pump is connected with circulating water pool; Described notes lubricated slurry pipe 14 is connected with mudjack by constant-pressure tank.
During concrete the use, by being provided with a minute storehouse partition ring at the first injected hole 0.05m place, 10 front side and rear side every the 30m place, so that whole pipe curtain steel pipe 1 forms N the monomer drag reduction slurry collar in the soil body, play the effect that whole drag reduction is starched balanced drag reduction.And during jacking, injected hole on development machine 3 afterbodys and the pipe curtain steel pipe 1 will be followed the tracks of mud jacking timely and effectively, remain that the annular gap mud pressure is played a supporting role to surrounding soil greater than soil pressure and water pressure sum in the jack-in process, guarantee to form complete effective mud sleeve.Simultaneously during jacking construction, also need frequent sensed water level line in order in time force value is revised.
In the utility model, the move speed of pipe curtain steel pipe 1 depends primarily on the shield machine pace, and the restriction that the pace of shield machine mainly is subjected to cutterhead 4 moments and advances sludge drainage system.When shield machine is eaten soil when advancing to discharge the soil body greater than jacking, easily form the soil body that causes of backbreaking and cave in, should improve move speed; When shield machine is eaten soil when advancing to discharge the soil body less than jacking, easily cause cutterhead overload, should reduce move speed, determine that move speed can effectively control high efficiency, improve the push pipe quality; Observe the laser spots that is positioned on the development machine 3 afterbody light targets by monitor in progradation, the light target center namely is the development machine center, and laser spots is the pipe design center.When producing deviation, regulate 4 controlling parties in the development machine 3 to jack by console, make development machine 3 can change its attitude, draw close to design direction, can fast, simply control the jacking precision well.
