Problems solved by technology
After the top is in place, the remaining distance of about 1m is usually manually excavated and directly poured concrete to form a ring. At this time, the cast-in-place part and the pipe jacking joints on both sides are three independent entities, and the integrity is poor. The connection part of the middle butt joint is prone to misalignment, which will lead to problems such as water leakage
have an extremely adverse impact on subsequent operations

Embodiment Construction
[0036] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the advantages of the present invention are clearer and easier to understand through the description.
[0037] Referring to the accompanying drawings, it can be seen that the hand-excavated pipe jacking butt joint connection structure includes a prefabricated structure 1 and a cast-in-place structure 2. The pipe joint 13 is docked in the middle; the present invention performs soil cutting and advanced support on the prefabricated structure 1 to increase structural stability and improve docking accuracy;
[0038] The cast-in-place structure 2 includes an Ω steel plate 21, a water-stop structure 22 and structural concrete 23; the Ω steel plate is used to solve problems such as water leakage caused by staggered platforms;
[0039] The Ω steel p...

The invention discloses a hand-digging pipe-jacking butt joint connection structure. The hand-digging pipe-jacking butt joint connection structure comprises a prefabricated structure and a cast-in-place structure, wherein the prefabricated structure is positioned on a first pipe-jacking pipe segment; the cast-in-place structure is positioned in a butt joint middle part between pipe-jacking pipe segments on both sides; the cast-in-place structure comprises an omega steel plate, a water stop structure and structural concrete; the omega steel plate is closely attached to an inner side of the prefabricated structure; and the water stop structure is closely attached to a soil side of the prefabricated structure. The hand-digging pipe-jacking butt joint connection structure has the advantages ofrelatively high integrity and capability of preventing water leakage due to staggering during pipe jacking. The invention further discloses a construction method for the hand-digging pipe-jacking butt joint connection structure.
Description
technical field [0001] The invention relates to the technical field of civil engineering, and more specifically relates to a hand-digging type pipe jacking butt joint connection structure. The invention also relates to the construction method of the hand-excavated pipe jacking butt joint connection structure. Background technique [0002] In the field of civil engineering, pipe jacking technology is widely used, especially in areas where surface deformation needs to be controlled. Pipe jacking technology is divided into mechanical pipe jacking and hand digging pipe jacking. Among them, hand digging pipe jacking is widely promoted because of its simple equipment and low technical difficulty. [0003] Hand digging pipe jacking has great dependence on geological conditions. When the pipe jacking distance is long, the pipe jacking faces problems such as high pipe jacking resistance and difficult advancement. At this time, it needs to be jacked from both sides. After the top i...
