2. The wall bushing 1 is arranged at the wall penetrating position of the branch pipe, and primary plugging of the bushing is performed, so that the influence of displacement on the bushing during later-stage masonry construction is avoided.
3. The positions of the masonry and the structure construction are influenced, reservation is carried out, and the sleeve is embedded along with the masonry.
4. A drain valve for pressure test is reserved at the tail end of the branch pipe.
5. And after the pipeline construction is finished, protecting the finished product of the pipeline.

As a preferred embodiment, in addition to the above-mentioned mode, further, when the main pipe is erected and the branch pipe is erected, the pipeline close to the wall and/or the beam is constructed firstly, and then the pipeline far away from the wall and/or the beam is constructed; the upper layer pipeline is constructed firstly, and then the lower layer pipeline is constructed. By adopting the method, the space used by the building during construction can be increased to the maximum extent, and secondary construction caused by pipeline conflict is reduced, so that the construction period is further saved.
In a preferred embodiment, in addition to the above-described embodiment, the wall bushing 1 is provided at a portion that passes through the main structure during the installation of the branch pipe.
In the embodiment, the inventor considers the erection mode that the branch pipe passes through the main structure, and the branch pipe is easy to rub against the main structure in the installation process, so that the branch pipe is damaged. And in later use, the pipe flutter due to the "water hammer effect" further exacerbates branch damage. In this respect, in the present embodiment, the inventor provided the wall bushing 1 at a portion crossing the main structure when installing the branch pipe. In the mode of avoiding such branch pipe erection, the branch pipe body directly contacts with the concrete structure, causes its own damage to avoided the branch pipe to erect because of the unqualified secondary construction of quality, further practiced thrift construction period again. Meanwhile, after the arrangement, the service life of the branch pipe is prolonged to a certain extent, and the operation stability of a pipeline system is improved.
In a preferred embodiment, in addition to the above-described embodiment, the wall bushing 1 is further subjected to a plugging treatment after the completion of the branch erection.
Specifically, the inventor in this embodiment considers that, in the process of installing the branch pipe, the installed branch pipe may shake, and if the wall bushing 1 is plugged along with the installation of the branch pipe, the shake generated in the installation process may cause the plugging failure of the wall bushing 1, so that a secondary rework situation may occur. In this embodiment, the wall bushing 1 is plugged after the branch pipe is erected. The problems are effectively avoided, and the construction period is further saved.
In a preferred embodiment, in addition to the above-described embodiment, a pressure test experiment of the pipeline is performed after the erection of the trunk pipe and the branch pipe is completed.
In a preferred embodiment, in addition to the above-described embodiment, the cable is erected after the pressure test is passed. By adopting the method, the cable is prevented from being damaged in the pressure test process of the pipeline, so that the pipeline is prevented from being reworked for the second time. Meanwhile, the cable is prevented from being reworked for the second time due to unqualified pipeline pressure test.
Example 4
As shown in fig. 1 to 4, based on the above manner, the wall bushing 1 according to the present invention includes a bushing body 2 and a bushing lining 3, the bushing lining 3 is disposed around an inner wall of the bushing body 2 and forms an internal cavity structure, the bushing lining 3 is made of a flexible material, a branch pipe penetrates into the wall bushing 1, and the bushing lining 3 covers the branch pipe to prevent the branch pipe from contacting the bushing body 2.
In this embodiment, the inventor considers that the pipe may have a "water hammer effect" due to sudden power failure or when the valve is closed too fast in later use, which may cause the branch pipe to shake. When the branch pipe shakes, the branch pipe may contact with the wall bushing 1 and transmit force to the building main body, so that the branch pipe itself or the building main body is damaged. Based on this, in this embodiment the inventor set up the sleeve inside lining 3 in the sleeve body 2, sleeve inside lining 3 adopts flexible material to make, can absorb the shake that the branch pipe produced, has avoided branch pipe contact wall bushing 1 to transmit power to the building main part to the stability after the operation of pipeline system has been improved.
In a preferred embodiment, in addition to the above, an end of the jacket lining 3 is provided at a distance from an end of the jacket main body 2.
In the above scheme, the inventor has avoided the branch pipe to contact with sleeve body 2 when producing the shake and transmit power to the main building body through setting up sleeve inside lining 3, causes the damage of branch pipe itself or the damage of main building body. Thereby improving the stability of the pipeline system after operation. However, the defects still exist, only for the branch pipe passing through the main structure part, when the 'water hammer effect' is generated, the shaking amplitude of the end part of the branch pipe in the shaking transmission process is often larger than that of the middle part of the branch pipe, and the situation that the end part of the branch pipe continuously impacts the wall bushing 1 occurs, and for the main structure of the area where the wall bushing 1 is arranged, the acting force transmitted by the wall bushing 1 just falls on the part with relatively weak structural strength, so that the part is easy to crack. Based on this, in the present embodiment, the inventors set the end of the jacket lining 3 at a distance from the end of the jacket body 2. Therefore, the acting force applied to the two sides of the end part of the building main body which is penetrated by the branch pipe or the sleeve pipe body 2 is weakened, so that the building main body is prevented from being damaged to the greatest extent, and the later maintenance cost is reduced.
In a preferred embodiment, in addition to the above manner, the thickness of the bottom of the casing liner 3 is larger than that of the top.
In the present embodiment, the inventor considers that the pipe branch itself has a certain mass, which may cause a certain compression on the casing lining 3, resulting in a reduced ability of the casing lining 3 to absorb pipe branch shaking, and particularly when the pipe branch is filled with liquid, the casing lining 3 compressed by the compression portion may be greatly deformed, and almost lose the ability to absorb pipe branch shaking. Also, and the inventors considered that the counter-force of the pipe branch in the presence of whipping is mainly concentrated at the bottom of the casing lining 3. In this embodiment, the inventors set the thickness of the bottom of the casing liner 3 to be greater than the thickness of the top. Through improving the ability that the shake of branch pipe is absorbed at 3 bottoms of sleeve pipe inside linings, overcome the oppression that the branch pipe caused to it to avoided branch pipe contact wall bushing 1 to transmit power for the building main part, further improved the stability after pipeline system's the operation.
In a preferred embodiment, in addition to the above aspect, the sleeve liner 3 further includes a first liner portion 4, a second liner portion 5, and a third liner portion 6, the second liner portion 5 is provided between the first liner portion 4 and the third liner portion 6, an elastic deformation coefficient of the second liner portion 5 is smaller than those of the first liner portion 4 and the third liner portion 6, and a length of the second liner portion 5 is larger than those of the first liner portion 4 and the third liner portion 6.
In the present embodiment, the inventor considered that in the above-described embodiment, the end of the jacket liner 3 is disposed at a distance from the end of the jacket body 2. The acting force applied to the two sides of the end part of the building main body which is penetrated by the branch pipe or the sleeve pipe body 2 is weakened, so that the building main body is prevented from being damaged to the greatest extent, and the later maintenance cost is reduced. However, there is still a disadvantage that in the above-described solution, when the branch pipe is shaken to a large extent, there is a case where the branch pipe or the socket body 2 presses both sides of the end portion of the building main body where it passes. In view of this, in the present embodiment, the elastic deformation coefficient of the second liner portion 5 is set smaller than the elastic deformation coefficients of the first liner portion 4 and the third liner portion 6, and the length of the second liner portion 5 is set larger than the lengths of the first liner portion 4 and the third liner portion 6. Through strengthening the restriction force of the second lining part 5 on the branch pipe, the part of the branch pipe or the sleeve pipe body 2 applying pressure to the building main body is transferred to the middle part of the main structure through which the branch pipe passes, so that the situation that the branch pipe or the sleeve pipe body 2 transmits the force to the end part of the branch pipe passing through the main structure is effectively avoided, and the middle part of the main structure is passed through by the branch pipe, because the contact area between the branch pipe or the sleeve pipe body 2 and the structure strength of the branch pipe is large and the structure strength of the branch pipe or the sleeve pipe body is high, the acting force transmitted to the branch pipe or the sleeve pipe body can be effectively offset, the building main body is effectively prevented from being damaged, and the later maintenance cost is further reduced.
In a preferred embodiment, in addition to the above-described embodiment, the diameter of the cavity of the second lining portion 5 is smaller than the diameter of the cavity of the first lining portion 4 and the third lining portion 6.
In this embodiment, the amount of ineffective deformation of the casing liner 3 can be effectively consumed by the pressing of the casing liner 3 by the branch pipe after the penetration. The ineffective deformation amount, that is, the deformation amount which cannot suppress the continuation of the shaking when the shaking is generated in the branch pipe, in the present embodiment, the diameter of the cavity of the second liner portion 5 is set smaller than the diameter of the cavities of the first liner portion 4 and the third liner portion 6. The second lining part 5 can be made to consume more ineffective deformation by the branch pipe, so that the limiting force of the second lining part 5 on the branch pipe is further improved, the branch pipe or the sleeve pipe body 2 can better transmit the force to the branch pipe to penetrate through the middle position of the main structure, the building main body is effectively prevented from being damaged, and the later maintenance cost is further reduced.
In a preferred embodiment, in addition to the above-described aspect, the second lining portion 5 is provided so as to be separated from the first lining portion 4 and the third lining portion 6.
In the present embodiment, the inventor considers that the deformation amount of the casing liner 3 absorbing the pipe shaking may be different due to the difference between the deformation coefficients of the second liner portion 5 and the first liner portion 4 and the third liner portion 6, and thus an uncontrollable cracking may occur at the joint of the second liner portion 5 and the first liner portion 4 and the third liner portion 6, so that the first liner portion 4 and/or the second liner portion 5 and/or the third liner portion 6 may lose the capability of absorbing the pipe shaking. Based on this, in the present embodiment, the inventors disconnected the second lining portion 5 from the first lining portion 4 and the third lining portion 6. The second lining portion 5 is separated from the first lining portion 4 and the third lining portion 6 by actively arranging a gap on the sleeve liner 3, so that the situation that uncontrollable cracking occurs at the joint of the second lining portion 5 and the first lining portion 4 and the third lining portion 6 is effectively avoided, and the reliability of the wall bushing 1 in practical application is improved.
