Technical Field
The utility model relates to an L-shaped sealing bush device for a concrete pipeline joint, and belongs to the technical field of drainage pipeline construction.
Background
The reinforced concrete faucet and the tongue-and-groove pipeline are widely applied to municipal drainage engineering due to good large-diameter ring rigidity, construction convenience and concrete durability, and are mainly used as municipal road or field rain sewage drainage pipelines. At present, the sealing of the pipeline joint is commonly realized by adopting a rubber ring for extrusion sealing. However, the rubber ring is easy to slip in the socket and spigot process after being installed due to the influence of the field construction installation technique, the leakage prevention effect is generally poor due to loose displacement of the pipeline, and the qualification rate of the water closing test is low. What is needed is a joint sealing device with convenient and stable construction and installation and stable anti-leakage effect.
Disclosure of utility model
Based on the above, the utility model provides an L-shaped sealing bushing device for a concrete pipeline joint, which is used for solving the problems that the reinforced concrete pipeline joint is easy to slip in the socket joint process and the joint leakage-proof effect is poor.
The technical scheme of the utility model is as follows: an L-shaped sealing liner device for use at a concrete pipe joint, comprising:
the L-shaped rubber bushing is formed by connecting a vertical part and a transverse part;
The L-shaped framework is embedded in the L-shaped rubber bushing;
the front rubber ring is connected to the free end of the vertical part;
And the rear extrusion rubber ring is connected with the free end of the transverse part.
In one example, the L-shaped framework is made of L-shaped thin steel plates.
In one example, the thickness of the front rubber ring is greater than the thickness of the vertical portion.
In one example, the tail part of the rear extrusion rubber ring is bifurcated into an upper layer and a lower layer.
In one example, the thickness of the rear extrusion rubber ring is larger than that of the transverse part
The utility model has the beneficial effects that: the utility model effectively solves the problems that the reinforced concrete pipeline interface is easy to slip and has poor anti-seepage effect in the process of socket joint, and ensures wider application range of the reinforced concrete pipeline. Specifically, the L-shaped framework is arranged in the L-shaped rubber bushing, so that the shape of the L-shaped rubber bushing can be effectively fixed, the original shape of the L-shaped rubber bushing is ensured in the construction and installation process, and the sealing rubber ring of the device has the extrusion sealing effect. The front and rear anti-seepage extrusion rubber rings are arranged on the L-shaped rubber bushing, when the anti-seepage rubber rings are assembled with the socket joint female port of the concrete pipeline, the rear extrusion rubber rings are attached and deformed by the extrusion of the upper and lower rubber rings, so that the child port and the female port are assembled more tightly, the water seepage outside the pipeline is avoided, the anti-seepage effect is influenced, and the front rubber rings arranged on the inner side of the concrete pipeline can prevent water seepage from the inner side of the pipe to the outer side of the pipe.

Detailed Description
In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit or scope of the utility model, which is therefore not limited to the specific embodiments disclosed below.
Referring to fig. 1 and 2, an L-shaped sealing liner device for a concrete pipeline joint according to the present embodiment includes an L-shaped rubber liner 3, an L-shaped framework 2, a front rubber ring 4 and a rear extrusion rubber ring 1. The L-shaped rubber bushing 3 is formed by connecting a vertical part and a transverse part, an L-shaped framework 2 is arranged in the L-shaped rubber bushing, and the L-shaped framework 2 is made of L-shaped thin steel plates. The free end of the vertical part is connected with a front rubber ring 4, and the thickness of the front rubber ring 4 is larger than that of the vertical part. The free end of the transverse part is connected with a rear extrusion rubber ring 1, the thickness of the rear extrusion rubber ring 1 is larger than that of the transverse part, and the tail part of the rear extrusion rubber ring 1 is bifurcated into an upper layer and a lower layer. It should be noted that the L-shaped framework 2 should be fitted with the spigot and socket sub-mouth 5 of the concrete pipe.
The process for sealing the joint of the concrete pipeline by adopting the L-shaped sealing bushing device comprises the following steps:
Firstly, an L-shaped sealing bushing device is positively arranged on a spigot and socket joint 5 of a concrete pipeline to be installed, and rubber hammers are symmetrically knocked around until the sealing bushing device is completely sleeved into the spigot and socket joint 5 of the concrete pipeline; hoisting the concrete pipe by using hoisting equipment, and aligning the concrete pipe with the socket and spigot female port 6 of the last pipeline; then, the sub-ports of the mounting pipeline are uniformly and axially inserted into the main port of the previous pipeline by adopting the matching of a chain block and a steel clip, and tightly pressed; adjusting the straightness and elevation gradient of the pipeline to meet the requirements; finally, 1 is adopted outside the pipe orifice: 2 cement mortar 7 is plastered and sealed as a first seepage-proofing process.
According to the utility model, the L-shaped framework 2 is arranged in the L-shaped rubber bushing 3, so that the shape of the L-shaped rubber bushing 3 can be effectively fixed, the original shape is ensured in the construction and installation process, and the sealing rubber ring of the device has the extrusion sealing effect. The front and rear anti-seepage extrusion rubber rings are arranged on the L-shaped rubber bushing 3, when the anti-seepage rubber bushing is assembled with the concrete pipeline socket female port 6, the rear extrusion rubber ring 1 is attached and deformed by the extrusion of the upper and lower rubber rings, so that the assembly of the child port and the female port is more compact, the water seepage outside the pipeline is avoided, the anti-seepage effect is influenced, and the front rubber ring 4 arranged on the inner side of the concrete pipeline can prevent the water seepage from the inside of the pipe to the outside of the pipe.
The foregoing examples illustrate only a few embodiments of the utility model and are described in detail herein without thereby limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
