Abstract
The utility model relates to a pipeline anti-displacement inspection well. The pipeline anti-displacement inspection well comprises a well seat and branch pipes; a vertical bell end is formed at the upper end of the well seat; well seat pipe connecting ports which are formed symmetrically are formed at the lower end of the well seat; a plurality of strengthening ribs are arranged on the pipe walls of the well seat pipe connecting ports; a sealing ring is arranged between every two strengthening ribs; a circle of concave rings which are concave inward are formed on the outer walls at the heads of the well seat pipe connecting ports; a flaring section is arranged at the end of each branch pipe interface connected with the well seat pipe connecting port; convex rings which are formed corresponding to the concave rings are arranged on the inner walls at the roots of the flaring sections; the well seat pipe connecting ports are inserted into the flaring sections of the branch pipe interfaces; the concave rings at the heads of the well seat pipe connecting ports are buckled with the convex rings at the roots of the flaring sections. By the pipeline anti-displacement inspection well, the problem of the displacement of the branch pipes in an installation process is prevented by the snap connection between the concave rings and the convex ring, so that the reliability of the connection between pipes is improved, and the sealing performance is enhanced.
Description
Technical field
The utility model relates to the manhole technical field, the anti-displacement of especially a kind of pipeline manhole.
Background technology
Manhole is applicable to the rain sewage vent line and looks into for the maintainer manual inspection, eliminate the ancillary structure of foreign matter, to be convenient to make regular check on and dredging pipeline, prevent the requisite measure of line clogging, manhole commonly used adopts combining structure, usually by the well seat, pit shaft, well lid, the compositions such as cage and concrete support plate, the urban road bottom need be buried rainwater underground at present, sewage, the various pipelines such as water supply, just be provided with corresponding manhole on the surface course, and be connected the safety whether sealing relationship the pipeline circulation between manhole and the inlet and outlet pipe lines, be connected the gluing mode that adopts that comprises between conventional manhole and the pipeline, with pipeline in line check well bellmouth, make to stick with glue and connect, though this kind mode can firmly connect for the moment, but can not symmetrical backfill meeting in the backfill process affecting glue comes unstuck, thereby cause the seepage leakage phenomenon, even that is to say that present pipeline bonding strength is inadequate.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provide the anti-displacement of a kind of pipeline manhole.
The technical scheme that its technical problem that solves the utility model adopts is: the anti-displacement of a kind of pipeline manhole, comprise well seat and arm, described well seat upper end is vertical bellmouth, well seat lower end has the symmetrically arranged well seated connection mouth of pipe, be provided with the multi-turn reinforcing rib on the tube wall of the described well seated connection mouth of pipe, be provided with sealing ring between the described reinforcing rib, be positioned at and have the depression circle that a circle concaves on the well seated connection mouth of pipe head outer wall, the arm interface end that links to each other with the well seated connection mouth of pipe has flared section, has the projection circle that arranges corresponding to the depression circle on the described flared section root inwall, the described well seated connection mouth of pipe is inserted in the flared section of an interface tube, and well seated connection mouth of pipe head depression circle is interlockingly connected with the projection circle of flared section root.
Further, the cross sectional shape of described depression circle and projection circle is semicircle or triangle.
The beneficial effects of the utility model are that the utility model has prevented from occurring in the arm installation process problem of displacement, thereby also just improved the reliability that connects between the tube and tube by adopting the depression circle to be connected with the hasp of projection circle, strengthened sealing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A place enlarged drawing of Fig. 1.
Among the figure: 1. well seat, 11. vertical bellmouths, the 12. well seated connection mouths of pipe, 13. reinforcing ribs, 14. depression circles, 2. arm, 21. flared section, 22. projection circle, 3. sealing rings.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Such as Fig. 1 Fig. 2, the anti-displacement of a kind of pipeline manhole, comprise well seat 1 and arm 2, well seat 1 upper end is vertical bellmouth 11, well seat 1 lower end has the symmetrically arranged well seated connection mouth of pipe 12, be provided with multi-turn reinforcing rib 13 on the tube wall of the well seated connection mouth of pipe 12, be provided with sealing ring 3 between the reinforcing rib 13, be positioned at and have the depression circle 14 that a circle concaves on the well seated connection mouth of pipe 12 head outer walls, the arm 2 interface ends that link to each other with the well seated connection mouth of pipe 12 have flared section 21, has the projection circle 22 that arranges corresponding to depression circle 14 on the flared section 21 root inwalls, the well seated connection mouth of pipe 12 is inserted in the flared section 21 of arm 2 interfaces, the well seated connection mouth of pipe 12 heads depression circle 14 is interlockingly connected with the projection circle 22 of flared section 21 roots, and the cross sectional shape of depression circle 14 and projection circle 22 is semicircle.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the manual, must determine its technical scope according to the claim scope.
