Embodiment

[0037] The purpose of the present invention is achieved through the following technical solutions:

[0038] Such as Figure 1-8 As shown, the present invention designs a special segment at the segment corresponding to the position of the main tunnel in the inter-area communication passage, adopts the combined design of the steel plate structure filled with concrete and the concrete segment, and leaves the interface position of the pipe jacking segment of the communication passage. The pipe jacking method is used to construct the communication channel. After the pipe jacking is completed, the ring beam at the opening is poured to form an integral communication channel structure.

[0039] During specific construction, the lining connection structure suitable for pipe jacking to implement communication channels mainly includes the following steps:

[0040] 1) if Figure 1~3 As shown, during the construction of the main tunnel, the pipes in the three annular lining rings arrange...

Abstract

The invention discloses a lining connecting structure applicable to a jacking pipe for implementing a connection passage. The lining connecting structure comprises a first lining ring, a second lining ring and a third lining ring which are in homocentric and side-by-side arrangement, wherein a concrete pipe segment is arranged at a pipe segment, corresponding to the cutting range part of the jacking pipe, of each lining ring, each concrete pipe segment is in surrounding arrangement with other pipe segments of each located lining ring through a concrete filling steel plate block along the two sides in the annular direction, and the integral lining ring is formed. Concrete can be adopted as a lining structure at the connection passage part implemented by the jacking pipe, and compared with the original steel pipe segment structure, the lining connecting structure has the advantages that the construction cost is reduced, in addition, the casting lining is convenient, and the maintenance cost is low; in addition, the construction of interval connection passages can be safely and efficiently ensured.

Description

technical field [0001] The invention relates to the connection structure of the section communication channel of the underground tunnel, in particular to a lining connection structure suitable for implementing the communication channel for pipe jacking. Background technique [0002] The construction methods of inter-section communication passages mainly include: open-cut method, underground excavation method, and open-excavation-first-underground-excavation method. Due to the narrow construction site in urban areas, traffic obstruction and environmental impact are not allowed, and freezing method is often used in soft soil areas. The freezing method has high soil strength and safe construction, but the construction cost is high and the construction period is long. Special freezing equipment and professional technical teams are required, and it will pollute the environment. Therefore, under the condition of tight construction schedule and increasing environmental protection r...
