Description

A kind of Novel anti-leakage push pipe

Technical field

The utility model belongs to push pipe leakage preventing structure design field, specifically a kind of Novel anti-leakage push pipe.

Background technique

Jacking construction is a kind of underground pipeline construction method grown up after shield-tunneling construction, it does not need to excavate surface layer, and can highway crossing, railway, rivers and creeks, above ground structure, underground structure and various underground utility etc., apply more and more extensive in the construction of the pipelines such as plumbing, coal gas, electric power, communication.But, often there are some problems in construction, affect construction quality in jacking construction unit construction equipment, technology, management level mixed.

In push pipe process, pipeline jacking axis is excessive with design misalignment of axe, pipeline is bent, even causes tube coupling to damage, interface seepage.Pipeline when advancing and surrounding soil exist and rub, this friction often makes soil body generation shear perturbation, causes the soil body move and cause surface subsidence.Not whole in tube coupling external form, when interface is uneven or pipeline is directly suitable, this shear perturbation will be aggravated, thus makes to produce gap between push pipe, produces the generation of leakage scenarios.Traditional push pipe of seepage that prevents seals, complex structure, and sealing effect is poor, and mending-leakage measure often adopts the method for epoxy-cement mortar or chemical grouting to process, and effect neither be fine.

Model utility content

It is simple that technical problem to be solved in the utility model is to provide a kind of structure, easy for installation, saves material, the Novel anti-leakage push pipe of good sealing effect.

The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of Novel anti-leakage push pipe, comprise the first push pipe and second push pipe of adjacent coaxial setting, one end inner circumferential wall of described first push pipe and the second push pipe all offers the first circular groove, the other end peripheral outer wall of described first push pipe and the second push pipe all offers the second circular groove matched with described first circular groove, one end that described first push pipe is provided with described first circular groove is inserted in one end that described second push pipe is provided with described second circular groove, and be socketed with the first seal ring at described first push pipe and the second push pipe joint.

Further, described first seal ring comprises inner ring and the outer ring of coaxial setting, the length of described inner ring is less than the length of described outer ring, between described second circular groove that described inner ring is socketed in described first push pipe and the second push pipe joint and the first circular groove, described outer ring sleeve is connected on the outside of described first push pipe and the second push pipe joint, described inner ring two ends are coaxially fixedly installed the second seal ring that external diameter is greater than the external diameter of described inner ring respectively, second seal ring described in one of them is by being connected the middle part of described outer ring with the connecting ring in the gap of the second push pipe joint through described first push pipe, in described first circular groove and the second circular groove of described first push pipe and the second push pipe joint, corresponding two described second seal rings offer sealed groove respectively, and described second seal ring is positioned at described sealed groove.

Further, described second seal ring and described inner ring one-body molded.

Further, described first seal ring and the second seal ring are rubber seal.

The beneficial effects of the utility model are: structure is simple, easy for installation, save material, good sealing effect.
