Abstract
The utility model provides a self-compaction reinforcing and impermeable guide pipe pipe-jacking device. A compaction plate is arranged along the inner side of the front end of a guide pipe in a whole loop direction or local direction, and can rotate around a rotary shaft. An included angle between the compaction plate and the guide pipe is changed, a wedge-shaped gap is arranged between the compaction plate and the guide pipe, a wedge-shaped rod which longitudinally moves along the guide pipe is arranged in the wedge-shaped gap, a screw rod welded on the wedge-shaped rod penetrates through a screw hole, the screw hole in a fixed plate is provided with an internal thread, and a nut on the screw rod is screwed, so that the wedge-shaped rod can longitudinally move along the interior of the guide pipe. The self-compaction reinforcing and impermeable guide pipe pipe-jacking device has the advantages that water does not fall in the process of large-caliber pipe-jacking in a water seepage stratum layer or a soft soil stratum layer, soil mass in the guide pipe is compacted by the compaction plate so as to achieve the aim of self-compaction reinforcing and impermeability, construction safety is good, ground surface settlement is easy to control, and good environmental benefits and social benefits are provided.
Description
Technical field
The utility model relates to the underground engineering construction field, and particularly a kind of self-compacting is reinforced and the first conduit pipe jacking equipment of antiseepage.
Background technique
In municipal administration and underground engineering construction field, the construction by pipeline jacking method application area is more and more extensive.When carrying out the heavy caliber pipe-jacking construction in weeping formation and soft soil layer, when adopting artificial or half mechanical process push pipe operation, being easy to occur infiltration at the push pipe front end collapses with the earthwork, bring risk to jacking construction, and the method for usually taking slip casting is during to push pipe front end earthwork pre-reinforcement, not only increased the engineering director costs and extended construction period, and the slurries of pre-reinforcement slip casting in early stage easily wrap push pipe, cause follow-up jacking forces in pipe-jacking sharply to increase with the push pipe distortion serious.In the heavy caliber pipe-jacking process, jacking construction again after precipitation, easily cause stratum settlement, causes underground utility to destroy and uneven settlement and the destruction of neighboring buildings.
The model utility content
The purpose of this utility model is in the push pipe process, precipitation not when realizing the heavy caliber pipe-jacking operation, shorten the duration of push pipe operation, guarantee the safety of heavy caliber pipe-jacking operation, provide a kind of self-compacting to reinforce and the first conduit pipe jacking equipment of antiseepage, solve in the jacking construction process soil body self-compacting in not precipitation and first conduit tube head front end or pipe reinforce with and the problem of antiseepage.
For achieving the above object, the utility model adopts following technological scheme:
A kind of self-compacting is reinforced and the first conduit pipe jacking equipment of antiseepage, along the inboard loopful of first conduit front end to or the part be furnished with compacted plate, compacted front edge of board has rotational axis hole, rotatingshaft passes rotational axis hole and is connected with the rotatingshaft bearing at first conduit cutting edge place; The compacted plate moving axis that can rotate rotates, change the angle between compacted plate and first conduit, compacted plate rear end is provided with caging bolt, on the corresponding first conduit in caging bolt position, fixed plate is arranged, fixed plate is welded on first pipe inner wall, limited location groove on fixed plate, caging bolt can be along moving in restraining groove; Have wedge gap between compacted plate and first conduit, in establish the tapered shaft that can vertically move along first conduit, the screw rod that welds on tapered shaft passes the screw that internal thread is set in fixed plate, turns the nut on screw rod, can make tapered shaft along vertically moving in first conduit.
Compacted plate can be along the inboard loopful of first conduit front end to arranging or local the layout.
The first conduit front end outside can be provided with stiffening ring.
Angle between compacted plate and first conduit needs to determine according to the characteristic of diameter, weeping formation or the soft soil layer of first conduit, can regulate the angle between compacted plate and first conduit in the push pipe process, to adapt to different formation conditions, realize that self-compacting is reinforced and the purpose of antiseepage.
The utility model has been installed the compacted plate of the soil body in the pipe that detachably also can regulate angle in the first conduit of heavy caliber pipe-jacking, carry out in weeping formation or soft soil layer in bigbore push pipe process, utilize the interior compacted plate of pipe carry out compacted to the soil body in first conduit and reinforce, reduce soil body penetration in pipe, realize in the push pipe operation process that not precipitation, soil body self-compacting are reinforced and the purpose of antiseepage.
