Description

Steel socket reinforced concrete pipeline with novel socket

Technical Field

The utility model relates to a reinforced concrete pipeline technical field, concretely says so and relates to a steel holds a mouthful reinforced concrete pipeline with novel socket.

Background

The reinforced concrete pipe is a common building component for conveying liquid media, and is widely applied to projects such as urban water supply and drainage, industrial water delivery pipelines, farmland irrigation, pressure tunnel pipelines and the like. The existing reinforced concrete pipe usually comprises a rigid connector and a flexible connector, wherein the rigid connector comprises a pipe-shaped plain end and a tongue-and-groove, and the flexible connector comprises a pipe-shaped branch socket and a steel collar connector. Wherein, socket pipe type has the leakproofness good, simple to operate, impervious better advantage and the widely used.

The installation of the pipe is an important working link in the construction process, and the installation of the concrete pipe means that two ends of a plurality of adjacent connecting pipes are sequentially connected end to end, for example, when two adjacent connecting pipes are connected together, the socket end of one connecting pipe needs to be pushed into the socket end of the other connecting pipe to complete the connection between the two connecting pipes.

In the actual work progress, can exist less degree of buckling sometimes because of the difference of arrangement position or because of the uneven settlement of ground or ground unevenness reason between two tubular products of connection, there is certain corner promptly between two tubular products, the tip of the female end of a connecting pipe very easily takes place the extrusion collision with the spigot end department of another connecting pipe this moment, lead to the female end to appear warping or the spigot end working face is destroyed, influence the leakproofness of connecting, lead to the condition that the infiltration appears between the connecting pipe, seriously influence construction quality and efficiency of construction.

Therefore, it is an urgent need to solve the problem of designing a reinforced concrete pipeline with a novel socket to adapt to the bending degree between two pipes.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of above-mentioned prior art, provide a steel socket reinforced concrete pipeline with novel socket, through offering cyclic annular arc recess in the department of linking to each other of socket end and body, do not make socket end relative socket end when removing with socket end rigid contact to avoid socket end or socket end the condition that damages appears, leakproofness when having guaranteed the body and connecting.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a steel socket reinforced concrete pipeline with novel socket, the pipeline includes the body, sets up at the inside steel reinforcement cage skeleton of body, sets up at the female end of body one end, sets up the socket end at the body other end, the female end is the female end steel loop, the socket end still has seted up the annular groove of arc with the continuous department of body, the utility model discloses the female end is terminal for the socket with the continuous department of body, also the annular groove of arc is seted up at socket end department promptly.

The utility model discloses in, the steel reinforcement cage skeleton can be with body integrative pouring fashioned, the steel reinforcement cage skeleton that has in the body has further strengthened the intensity of body.

And one end of the bellmouth steel ring close to the pipe body is welded with the steel reinforcement cage framework. The welded bellmouth steel ring is firmly connected with the steel reinforcement cage framework and the pipe body.

One end of the bellmouth steel ring, which is far away from the pipe body, is also provided with a certain bevel angle alpha (alpha is more than or equal to 20 degrees and less than or equal to 30 degrees). The setting of this groove angle alpha can make the one end that the body was kept away from to the bellmouth steel ring keep longer distance with the socket end to have certain permitted displacement distance between bellmouth steel ring and the socket end, this permitted displacement distance can make the bellmouth steel ring keep away from the one end of body and not contact with the socket end when the relatively small displacement appears between bellmouth steel ring and the socket end.

Two circles of annular grooves which are parallel to each other and have the same size and dimension are also formed in the outer side wall surface of the socket end, and wedge-shaped rubber rings are filled in the two circles of annular grooves respectively. When the socket end is used, after the socket end is pushed into the socket end, the bevel angle of the socket steel ring is arranged corresponding to the annular arc groove at the tail end of the socket end, when the socket end deflects relative to the socket end, one end part of the deflected socket steel ring, far away from the pipe body, extends into a cavity formed in the annular arc groove, the end part of the socket steel ring, far away from the pipe body, is not in rigid contact with the tail end of the socket end, so that the socket end has a certain allowable deflection distance relative to the socket end, the condition that the end part of the socket end and the tail end of the socket end are extruded and collided is avoided, deformation of the socket end or damage to the working surface of the socket end is avoided, the connection tightness of the pipe body is ensured, and the construction quality and the construction efficiency are greatly improved.

The utility model has the advantages that,

1. the utility model discloses in, the one end that the body was kept away from to the bellmouth steel ring and socket end keep longer distance, and the one end that the body was kept away from to the bellmouth steel ring when this distance can make appear relatively small displacement between bellmouth steel ring and the socket end does not with the terminal rigid contact of socket end, has effectively avoided the condition of bellmouth end or socket end damage.

2. The utility model discloses in, the socket end is provided with cyclic annular arc recess, when there is less degree of buckling between two connecting pipes, the cavity that cyclic annular arc recess had makes the bellmouth steel ring keep away from the one end of body and has certain skew distance, the hard contact does not appear in bellmouth steel ring and socket end, thereby effectively avoided leading to the bellmouth end to appear warping or the destroyed condition of socket end working face because of hard contact, strengthened tubular product and resisted the inhomogeneous settlement of ground, the ability of ground is uneven, the leakproofness of body coupling has been guaranteed, construction quality and efficiency are greatly improved.

3. The utility model discloses in, seted up two rings of annular grooves on the socket end outside wall, the wedge rubber ring in the recess is filled between annular groove and bellmouth steel ring, compares and sets up the wedge rubber ring in traditional single ring annular groove, all sets up the leakproofness that the pipe connection had been guaranteed to the wedge rubber ring in two rings of annular grooves.
