Abstract
The utility model provides a push pipe working well optimal design structure, including the working well, the working well is circular working well, and the wall of a well is pour by reinforced concrete, and the work well inner wall is hugged closely still to the inboard of working well and is under construction the auxiliary work well, has still pour the push pipe back wall with push pipe tunnelling one side relative in the auxiliary work well, and pour between push pipe back wall and the place side auxiliary work well and fill and have the concrete, push pipe back wall and auxiliary work well formula as an organic whole pour the structure, and push pipe back wall is perpendicular with push pipe tunnelling direction mutually. Poor, the excavation space is not enough and to the big problem of ground activity influence in order to solve the current push pipe work progress soil property condition, and the rectangle working well only back wall provides the jacking force for supporting, and the construction risk is big, leads to the jacking effect not good easily, the engineering accident scheduling problem that leads to the fact even. Belonging to the field of pipe jacking construction.
Description
Technical Field
The utility model relates to a push pipe working well optimal design structure belongs to push pipe construction field.
Background
With the rapid development of urban construction, the construction of urban underground engineering is increasing day by day. For the construction of underground engineering in formed sections of urban construction, the common open cut construction method in the construction process can not meet the construction requirements, and in order to meet the construction requirements, the trenchless engineering or trenchless construction process of pipe jacking construction is brought forward. The construction process is that the pipeline passes through auxiliary equipment without excavating layer and can pass through highways, railways, rivers, ground buildings, underground structures, various underground pipelines and the like.
The working well of current push pipe construction generally is the rectangle, and the soil property condition is poor in the work progress, excavation space is not enough and to the ground activity influence big, and the rectangle working well only back wall provides the jacking force for supporting after, and the construction risk is big, leads to the jacking effect not good easily, the engineering accident that leads to the fact even, the urgent need is solved.
Disclosure of Invention
The utility model provides a push pipe working well optimal design structure to solve the problem that the soil property condition is poor in the current push pipe work progress, the excavation space is not enough and influence is big to the ground activity, and the rectangle working well only back of the body wall provides the jacking force for supporting after, the construction risk is big, leads to pushing up easily that the effect is not good, the engineering accident scheduling problem that causes even.
In order to achieve the purpose, the optimized design structure of the pipe-jacking working well is designed, and comprises the working well, wherein the working well is a circular working well, the well wall is poured by reinforced concrete, an auxiliary working well is also constructed on the inner side of the working well and clings to the inner wall of the working well, a pipe-jacking back wall is further poured on one side, opposite to the pipe-jacking tunneling surface, of the auxiliary working well, concrete is poured and filled between the pipe-jacking back wall and the auxiliary working well on the side of the pipe-jacking back wall, the pipe-jacking back wall and the auxiliary working well are of an integrated pouring structure, and the pipe-jacking back wall is perpendicular to the pipe-jacking direction.
In the optimized design structure of the pipe-jacking working well, the height of the auxiliary working well is 2-3m lower than that of the working well, and the outer wall of the auxiliary working well is tightly attached to the inner wall of the working well;
in the optimized design structure of the pipe-jacking working well, the working well is phi 9m by 8.5m, the well wall is C30 reinforced concrete with the thickness of 0.6m, the auxiliary working well is phi 7m by 6m, and the well wall is C30 reinforced concrete with the thickness of 0.5 m.
Compared with the prior art, the utility model adopts the circular working well, the rectangular working well can effectively disperse the jacking force applied to the back wall, improve the structural stability and ensure the construction safety; the design of an auxiliary working well is added on the inner side of the working well, so that the jacking force of the jacking pipe is obviously improved on the basis of a single circular working well; the method has stronger adaptability, the improvement can effectively reduce the excavation area, reduce the influence on the ground movement caused by construction operation, and has less interference on the outside by the operation; the equipment occupies small space and has very important practical significance for pipe jacking construction.
