Description

Technical Field

[0001] The utility model belongs to the technical field of municipal integrated pipe gallery construction, and particularly relates to a construction structure for floating and deviation correction of an integrated pipe gallery. Background Technique

[0002] An integrated pipe gallery is an integrated space set in the underground pipeline in the city and is also a tunnel space set underground. Gas, heating, communication, electricity, etc. can be concentrated in this building. There are also special inspection openings, hoisting openings and monitoring systems, realizing the unified design and maintenance in the city. When designing the integrated pipe gallery, the anti-floating property during the use process of the structure is generally ensured by calculating the covering soil thickness or setting an anti-floating bottom plate. However, during the construction process, since the pipe gallery is constructed and backfilled in sections, when encountering special weather such as extremely heavy rain, the outside of the pipe gallery is easily blocked due to sectional backfilling, and the water flow is not smooth, resulting in inconsistent rising speeds of the water levels inside and outside the pipe gallery, forming too large a water level difference between the inside and outside of the pipe gallery, and causing the floating and displacement of the pipe gallery segments weighing nearly a thousand tons. At present, there is no mature deviation correction measure for the floating and displacement of the pipe gallery in the existing technology. Therefore, it is necessary to design a construction structure for floating and deviation correction of the integrated pipe gallery to solve the above problems. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a construction structure for floating and deviation correction of an integrated pipe gallery. This device solves the problem that the existing integrated pipe gallery is displaced during use and is difficult to correct and restore. It has the characteristics of simple structure, convenient construction, and can quickly and accurately complete the displacement and deviation correction of the integrated pipe gallery.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0005] A construction structure for floating and deviation correction of an integrated pipe gallery includes a cushion layer, and the pipe gallery is placed on the upper surface of the cushion layer; both sides of the pipe gallery are inclined slope structures; working pits are opened at the bottoms of the slope structures, a plurality of vertical jack bases are poured at the bottoms of the working pits, and a vertical groove is opened on the slope on one side of the working pit, and a back wall is poured in the vertical groove.

[0006] Preferably, a vertical jack is fixed on the upper surface of the vertical jack base, and the jacking point at the front end of the vertical jack cooperates with the lower surface of the pipe gallery.

[0007] Preferably, a horizontal jack is fixed on the side surface of the back wall, and the jacking point at the front end of the horizontal jack cooperates with the side surface of the bottom plate of the pipe gallery.

[0008] Preferably, a first steel plate is padded between the horizontal jack and the surface of the pipe gallery; a second steel plate is padded between the vertical jack and the surface of the pipe gallery.

[0009] The beneficial effects of the construction structure for the floating and deviation correction of the utility tunnel provided by the present utility model are as follows:

[0010] This device provides a specific structure for the construction of floating and deviation correction of the utility tunnel. The deviation correction construction of the utility tunnel is divided into several parts, including horizontal jacking deviation correction, cleaning the bottom of the utility tunnel, vertical jacking deviation correction, and filling the working pit, providing a feasible construction structure for the deviation correction construction after the floating and displacement of the utility tunnel. With the corresponding construction technology, the deviation correction of the floating and displaced utility tunnel can be completed quickly and accurately, ensuring that the utility tunnel meets the use function and construction quality acceptance requirements after the deviation correction and reset.
