Description

A kind of underground pipeline construction conduit jacking

Technical field

The utility model relates to underground buried tube conduit jacking field, in particular to a kind of underground pipeline construction conduit jacking.

Background technique

With the continuous development of pipe-jacking technology, the construction technology of jacking construction operation is more and more, but in work zone The soil property in domain, operating environment have certain requirement；And at present in the region of Economic contrast prosperity, often underground obstacle compares More, greatly, push pipe length is long, and required precision is relatively high, frequently results in the failure of push pipe for local soil property variation.

Now with the development of society, the requirements for pipes such as electric power, telecommunications, combustion gas, water supply and drainage are more and more, generally require Cross road, especially campus, factory, cell.And it excavates pipe trench and is laid with these pipelines and need to abolish road surface, existing pipe jacking equipment It is huge, it needs to excavate preparation hole greatly, is not suitable for using in campus, factory, cell.

Notification number is that the Chinese patent of CN206707711U is disclosed including tube body, and giant is provided in tube body, is shone Bright lamp and compressed air spray head, the cavity bottom of tube body are extended with mud extraction pipe, are provided with compressed air gold in the second cavity Belong to pipeline and high pressure water metal tubes, support plate, compressed air spray head and headlamp are fixed between the first watertight door and tube body It is fixed in support plate, the door body size on the first watertight door is less than the door body size on the second watertight door.The underground of the utility model Pipeline construction conduit jacking is strong to soil layer conformability, visible to barrier before push pipe, and it is easy to remove barriers.

The underground pipeline construction conduit jacking of above scheme can soften soil layer, sprayed water by high-pressure water pipe and carry out soil Layer softening, and extracted out cement by mud tube, because the pressure of sub-surface is larger, mud the asking there are splashes of extraction Topic, influence the staff or people crossing the road of surrounding, can not outdoor direct progress, need to establish additional maintenance device.

Utility model content

The purpose of the utility model is to provide a kind of underground pipeline construction conduit jackings, its advantage is that: having prevents waste material The advantages of splashing.

The above-mentioned technical purpose of the utility model has the technical scheme that a kind of underground pipeline construction Conduit jacking, including tube body, the bottom are extended with mud extraction pipe, and the mud extraction pipe end is fixed with aerial drainage dress Set, the discharge device includes surge bunker, and the surge bunker includes the upper housing being oppositely arranged, lower case, the upper housing, under The cross section of shell is domed, the upper housing, lower case inner wall be equipped with several buffering comb teeth, the upper housing, lower case Opposite straight edges be equipped with sealing element, the upper housing, lower case close mud extract out pipe side be respectively equipped with half round cut, The lower case bottom is equipped with the sustained release seat released for mud.

By using above-mentioned technical proposal, the soil block area more hard for some soil properties needs giant to fill the water, So that soil property is soft, then extracts pipe out by mud and extracted out, pipe is extracted out in mud by the way that upper housing, lower case are distinguished inlay card End, then upper-lower casing is connected by sealing element, to will enter surge bunker after mud is released from mud extraction pipe, and lead to Upper housing, the lower case of arch are crossed, so that being gentle confined space inside surge bunker, to slow down the fluctuation of water flow, is buffered Comb teeth does not influence the flowing of mud, and can hinder the flow velocity of mud, to slow down flow velocity, so that the speed of mud outflow Reduce with impulse force, so that mud to be slowly discharged to specified place from the sustained release seat outflow below lower case, prevents pollution week Collarette border.

Preferably, the sustained release seat includes the leak-off pipe for being connected to surge bunker, labyrinth is equipped in the leak-off pipe.

By using above-mentioned technical proposal, mud is slowed down in surge bunker, reduces certain impulse force, but release When there are still certain spouting velocity, by the camber on labyrinth, so that mud also is keeping subtracting at the last moment in outflow Speed, to further prevent injection and splash.

Preferably, the end of the leak-off pipe is equipped with supporting leg, the end of the supporting leg is equipped with sucker.

By using above-mentioned technical proposal, leak-off pipe generates movement, the supporting leg added when mud releases in order to prevent It prevents mud to be directly impinging ground, gives certain buffering, to reduce the movement of discharge device, sucker is further increased The fixation dynamics of discharge device and ground, has advanced optimized structure.

Preferably, the sealing element includes outwardly extending first attachment base of two straight flanges of upper housing, lower case two Outwardly extending second attachment base of straight flange is respectively separated equipped with several threaded connections on first attachment base, the second attachment base Hole.

By using above-mentioned technical proposal, the first attachment base and the second attachment base of extension increase upper housing, lower case Between contact area, and reinforce mutual attachment force by multiple threaded holes, structure optimized while operation readiness is convenient.

Preferably, the straight flange of first attachment base is equipped with raised line, the raised line edge with respect to the side of the second attachment base The straight flange length direction of first attachment base is arranged, and the straight flange of second attachment base is recessed with respect to the side of the first attachment base There is the recessed bar slot for raised line fitting insertion.

By using above-mentioned technical proposal, raised line and recessed bar slot increase connecing between the first attachment base and the second attachment base Contacting surface product, the design of grafting further enhances the leakproofness in buffering cabin each other, prevents internal sewage from connecting from buffering cabin Place's exudation, enhances structural stability and leakproofness.

Preferably, being removably connected with regulating part between half round cut described in two groups, the regulating part includes fitting semicircle Outer wall, the fitting mud of notch extract the inner wall outside pipe out, and the outer wall is extended with the limiting card of fitting upper housing, lower case Item.

By using above-mentioned technical proposal, when encountering the different mud of caliber and extracting pipe out, if the aerial drainage dress that replacement is whole It is larger to set infrastructure cost, applicability is weaker, of different sizes, the adjusting that can be suitble to according to pipe diameter selection for the regulating part added Part, two groups of limit strips on outer wall are bonded the two sides of half round cut respectively, are convenient for grafting, thus realize assembling, so that thus Improve applicability.

In conclusion the utility model has the following beneficial effects: by the upper housing of surge bunker, the connection of lower case, Convenient for carrying out inlay card to mud extraction pipeline outer wall, the flow velocity of mud is hindered, to slow down flow velocity, so that mud flows out Speed and impulse force reduce, thus slowly from below lower case sustained release seat outflow, mud is discharged to specified place, is prevented Pollute ambient enviroment.
