Abstract
Balanced push pipe water and soil pressure monitoring instrument protection device of muddy water under high water condition, good hollow sleeve pipe, mobile base and soil pressure meter of installation before the push pipe construction. The in -process that starts through the height of adjusting the movable end, makes soil pressure meter slightly in the concave yield pipe wall, and the assurance is started process stagnant water heavy curtain and can not destroyed the soil pressure meter, treat the soil pressure meter totally through the stagnant water heavy curtain, mobile base's height is adjusted to the rethread, makes soil pressure meter be in the coplanar with the pipe wall in the outside, soil pressure meter will detect data and pass to the detector, and then nature water and soil pressure is monitored to the accuracy. This device is effectual solved high water pressure condition under, the problem that the soil pressure meter caused the damage of soil pressure meter is cuted because of the stagnant water heavy curtain that starts to the push pipe stage of starting.
Description
Technical field
The utility model relates in mire water equilibrium tube jack-in process a kind of protection of instrumentation device that Water And Earth Pressures is monitored in real time; be applicable to various hydrogeological condition, particularly in Slurry Balanced Pipe Jacking Construction, earth pressure gauge protection played a key effect under high hydraulic condition.
Background technology
Under high hydraulic condition in Slurry Balanced Pipe Jacking Construction process, grasp pipeline Water And Earth Pressures change in Natural Water soil pressure and jack-in process accurately, have very important effect to push pipe operation, thus instruct jacking operation further.Under high hydraulic condition, can the installation of earth pressure gauge device accurate measurements jack-in process Water And Earth Pressures value by decision with fixing and firmness.
Summary of the invention
For solving the problem, the technical solution adopted in the utility model is mire water equilibrium tube Water And Earth Pressures monitoring instrument protective device under high water condition, and this device comprises mobile base 1, cored screw 2, hollow bushing 3, screw 4, earth pressure gauge 5, detector 6; Wherein, mobile base 1 is U-lag structure, and cored screw 2 is arranged on the U-lag structural base of mobile base 1; Hollow bushing 3 is U-lag structure, and screw 4 is arranged on the U-lag structural base of hollow bushing 3; The U-lag diameter of described hollow bushing 3 is greater than the U-lag diameter of mobile base 1; Cored screw 2 passes through together with threaded engagement with screw 4.
Be fixed with earth pressure gauge 5 in the middle of cored screw 2, earth pressure gauge 5 is connected with detector 6 by cable.
Hollow bushing 3, mobile base 1 and earth pressure gauge 5 is installed before jacking construction.In origination process, by regulating the height of mobile base 1, making in the slightly recessed tube wall of earth pressure gauge 5, ensureing that origination process sealing heavy curtain can not destroy earth pressure gauge 5; Treat earth pressure gauge 5 completely by sealing heavy curtain, then by regulating the height of mobile base 1, make earth pressure gauge 5 outermost and tube wall be in same plane, detection data are passed to detector 6 by earth pressure gauge 5, and then accurate measurements Natural Water soil pressure.Under this device effectively solves high hydraulic condition, the problem that the push pipe stage of starting causes earth pressure gauge to damage because of the sealing heavy curtain shearing earth pressure gauge that starts.
