Description

Technical Field

[0001] The utility model relates to the technical field of reinforced concrete drainage pipe jacking, in particular to a reinforced concrete jacking pipe with double rubber rings and a joint sealing detection pipe. Background Art

[0002] The construction of conventional reinforced concrete drainage pipe jacking joints presents a significant challenge: joint sealing cannot be immediately verified during installation. This means that even with rigorous monitoring and control during construction, it's still difficult to guarantee ideal sealing at every joint. This potential hazard, once exposed after the pipeline is fully installed and tested for water tightness, can cause significant disruption to the entire project.

[0003] Especially when leaks are discovered at joints, because the pipes are already buried deep underground, forming a hidden project, this means a lot of rework is required, and it may even be necessary to remove part of the installed pipes and reinstall and reseal them. Such rework not only wastes a huge amount of time and manpower, but also increases the financial burden of the project.

[0004] More seriously, if water leaks are not discovered and addressed promptly, they can have long-term negative impacts on the surrounding environment. For example, leaking sewage can contaminate groundwater and damage the ecological environment. In specialized applications like power pipeline corridors, pipe jacking leaks can also cause electrical safety incidents, posing a serious threat to people's lives and property. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model solves the problem of sealing the interfaces of common reinforced concrete drainage pipes.

[0006] A reinforced concrete jacking pipe with double rubber rings and a joint sealing detection tube includes a top socket steel ring, which is arranged on the outside of the top of the concrete jacking pipe. A detection tube is also provided on the top of the concrete jacking pipe, a detection tube socket steel ring is provided on the outside of the detection tube, a grouting pipe is provided at the lower end of the detection tube, a socket steel ring is also provided at the bottom of the concrete jacking pipe, and a fixed steel bar is provided at the upper end of the socket steel ring.

[0007] Furthermore, it also includes a socket steel ring, and sealant is filled between the socket steel ring and the concrete jacking pipe.

[0008] Furthermore, the fixed steel bars are arranged in two parallel rows.

[0009] Furthermore, it also includes that expansion strips are filled between the fixed steel bars.

[0010] Furthermore, a rubber ring groove is formed between the top socket steel ring and the detection tube socket steel ring.

[0011] Furthermore, the rubber ring groove is a rectangular groove.

[0012] Furthermore, the sealant is an annular structure with a right-angled trapezoidal cross section.

[0013] The beneficial effects of the present invention are as follows: the present invention solves the problem of reinforced concrete drainage pipes being installed at the construction site, and can immediately detect whether the joint seal is leaking. If there is a leak, the pipes are re-unplugged and re-checked before being installed again until the joint seal is qualified. This avoids the rework losses caused by unqualified closed water test after the pipeline installation is completed, and the contamination of groundwater by joint leakage in the later stage, which causes environmental pollution. In addition, the present invention has high strength, high impermeability, qualified interface sealing, and no leakage, which solves the problem of joint seal leakage commonly found in reinforced concrete drainage pipes currently used in domestic water supply and drainage pipelines (rainwater and sewage drainage, pressure sewage transportation, etc.).
