Specific embodiment

In the description of the present invention, it should also be noted that, unless otherwise clearly defined and limited, term " is set Set ", " installation ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, Or it is integrally connected；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, intermediary can also be passed through It is indirectly connected, can be the connection inside two elements.For the ordinary skill in the art, it can be managed with concrete condition Solve the concrete meaning of above-mentioned term in the present invention.

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Embodiment 1: as shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of pipeline is to sealing joint anti-sink structure, including pipeline sheet Body, this pipeline body are drainage pipeline, are embedded in the Prestressed concrete cylinder pipe of underground, pipeline body by socket duct 1, insert Mouth pipeline 2 is set with, and socket duct is equipped with female end 3, and socket pipeline is equipped with socket end 4, and female end is set in socket end, i.e., Female end and socket end be all it is matched, assembled is plug-in, is arranged on the outer wall at socket duct, socket pipeline docking There is the first sealant 5, the second sealant 6, the first sealant 5, are provided on the inner wall at socket duct, socket pipeline docking Two sealants 6 can seal socket duct, socket pipeline docking mouth more tight, it is not easy to the case where leaking, this reality Apply the first sealant in example, the second sealant is that expansion joint seals belt, and expansion joint seals between belt and duct wall YYPE layers are bonded with, expansion joint can be sealed belt and is bonded on the wall of pipeline by YYPE layers, since pipeline is PCCP pipeline, i.e., Pipe lining and outer wall are concrete mortar, so bonding for a long time to guarantee that expansion joint seals belt, it is necessary to select similar performance Binder, only similar performance meets phase patibhaga-nimitta and melts principle, it is ensured that the adhesion strength of durability could bond persistently, this YYPE layers are the biggish binder of intensity, which is cement, sand, rubber powder and penetrant crystalline small powder composition, expansion joint Band layer main body is polyethylene hydrocarbon, and single side is firmly bonded to water by binder containing the fiber heated, alkali resistance is good, fiber On the basal plane of mud, the elongation percentage of the expansion joint band is high, i.e., in the serious deflection of pipe joint generation, displacement, still It will not leak, while be provided with sealing ring 10 between socket end and female end, sealing ring help socket end is docked with female end With gluing, sealing.

Pipeline body inner wall is equipped with sink preventing apparatus, and sink preventing apparatus is mounted on socket duct 1, at 2 docking of socket pipeline, Anti-settling effect can be played, avoids collapsing since sedimentation socket duct is detached from the place of docking of socket pipeline, this sink preventing apparatus Including two Semicircular baffles 7, and two Semicircular baffles are symmetrically disposed on pipeline body internal upper part and lower part, i.e. two semicircles Shape baffle is respectively supported at pipeline to the upper semi-circle and lower half circle of interface, plays the role of supporting and blocking to interface, when holding Settling occurs in any one pipeline in mouthful pipeline 1, socket pipeline 2 when collapsing to underground, this Semicircular baffle 7 can share one Part power avoids the generation for collapsing offset to support pipeline, to more protect to interface, prevent due to collapsing and It is caused to be equipped with protrusion with socket duct, socket inner wall of the pipe contact position to interface tearing, leakage etc., while on Semicircular baffle 8, socket duct, socket inner wall of the pipe are equipped with matched card slot 9 corresponding with protrusion, i.e. protrusion on two Semicircular baffles It is stuck in corresponding card slot, and then the inner wall of Semicircular baffle and pipeline more attaches, two Semicircular baffles pass through fixed group Part is fixed, and fixation kit includes upper horizontal block 11, the lower horizontal block 12 being respectively arranged at two Semicircular baffle docking, upper horizontal block with Lower horizontal block is fixed by fixed column 13, i.e. after two Semicircular baffle symmetric supports are in pipeline, passes through upper horizontal block and lower horizontal block It is fixed, the fixed column upper half is equipped with screw thread, and upper horizontal block is equipped with the tapped through hole 14 to match with fixed column, lower horizontal block It is equipped with groove 15 corresponding with tapped through hole, fixed column 13 is installed in groove through tapped through hole, i.e. twisting fixed column 13, upper horizontal block 11 drives Semicircular baffle to will do it lifting, when the direction of control twisting fixed column, in the effect of tapped through hole 14 Under, when upper cross plate ramps up, so that the distance between Semicircular baffle and following Semicircular baffle above can become larger, simultaneously Since fixed column is withstood in groove, or less horizontal block can have an opposite effect power, i.e. two Semicircular baffles with upper horizontal block It can fit respectively with the upper half of pipeline and lower half, and Semicircular baffle is more steady in supporting to interface for pipeline Gu Semicircular baffle inner wall is coated with erosion resistant coating, erosion resistant coating can prevent from corroding this Semicircular baffle when draining, and erosion resistant coating can be adopted With painting PE material etc..

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
