Embodiment Construction

[0017] The features of the present invention and other related features will be further described in detail below in conjunction with the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the art:

[0018] Such as Figure 1-2 As shown, the labels 1-10 respectively represent: foundation pit 1, shield section 2, ordinary underground wall 3, ultra-short underground wall 4, short underground wall 5, steel cement-soil mixing pile 6, reinforced body 7, steel support 8. Reinforced concrete support 9. Reinforced concrete purlin 10.

[0019] Such as Figure 1-2 As shown, the foundation pit 1 is excavated along the surface road construction plan, and the shield interval section 2 passes through it. According to the length and width of the foundation pit 1, there are several underground walls distributed on both sides of the foundation pit 1. Due to the other Parts (such as two ends) have no influence on the description of the embodime...

Abstract

The invention relates to a civil engineering traffic construction industry foundation pit project, in particular to an enclosure structure of the foundation pit which is used under the foundation pit and carries out the shield structure zone tunnel crossing construction; the enclosure structure with the ultrashort underground wall comprises underground walls, steel supports, reinforced concrete supports and reinforced concrete enclosing purlins which are arranged among the underground walls, and is characterized in that the underground wall of the foundation pit in the crossing section range of the shield structure is the ultrashort underground wall, the wall toe of which is arranged under the top of the shield structure by no less than 0.5m; the short wall support of the underground wall embedded under the bottom of the foundation pit is transversely arranged between every pair of ultrashort underground walls at both sides of the foundation pit; the wall toe of the short wall support of the underground wall is flush with the wall toe of the ultrashort underground wall; the enclosure structure has the advantages that the enclosure structure can ensure the smooth crossing of the later stage shield structure, and compared with the traditional shield structure which passes through the glass fiber reinforced plastic underground wall, the enclosure structure reduces the risk and construction cost of the project.

Description

technical field [0001] The invention relates to a foundation pit project in the civil engineering, transportation and construction industry, in particular to an enclosure structure for a foundation pit under which a shield interval tunnel is crossed: an enclosure structure with an ultra-short underground wall. Background technique [0002] In urban transportation construction, it often happens that after the foundation pit structure is excavated on the ground, the shield section tunnel crossing construction is carried out below it. The construction of the foundation pit generally involves the surrounding enclosure structure: the reinforced concrete underground diaphragm wall cast on site, and usually in order to ensure the overall stability of the foundation pit during excavation, the insertion ratio of the underground wall is generally greater than 0.7. In other words, the tunnel boring machine will need to drill through the underground wall while the tunnel is being traver...
