Problems solved by technology

[0003] The current construction of the underpass structure requires various important construction links such as foundation pit support structure, earthwork excavation, and on-site pouring of various components. The construction period is long, the project investment is large, and there are interruptions, Unfavorable factors affecting current traffic

Embodiment Construction

[0021] see figure 1 , the "door" type sunken structure in this implementation is a prefabricated part prefabricated as a whole or in sections along the direction of road traffic; the cross section of the prefabricated part is in the shape of a "gate", forming a through-space section in the direction of road traffic ;A connection beam is set between the two side walls at the lower end of the "gate" structure to ensure the rigidity, strength and stability of the overall structure, and to keep the overall cut soil subsidence of the structural parts.

[0022] see figure 1 , figure 2 and image 3 , in specific implementation, the corresponding structure settings also include:

[0023] The bottom of the two sidewalls 2 is a blade foot 3 on the inner side, so as to facilitate the "door" structure as a whole to automatically realize the subsidence of the cut soil under the action of gravity, and reach the elevation of the designated position;

[0024] The two side walls 2 are pro...

Abstract

The invention discloses a door-shaped sunken structure for road intersection, which is characterized in that the door-shaped sunken structure is a prefabricated part which is prefabricated as a whole or in sections in the passing direction of a road; the cross-section of the prefabricated part is in a door shape and a thorough space section is formed in the passing direction of the road; and connecting beams are arranged between two side walls of the lower end of the door-shaped structure. The construction protection of a foundation pit timbering structure is not needed in the door-shaped sunken structure for the road intersection so that the construction period is shortened, the project investment is reduced, and the traffic does not have to be stopped.

Description

technical field [0001] The invention relates to a space structure form used for the interaction of urban roads, highways, and railways or with other objects, passing through and intercommunicating vehicles underneath. Background technique [0002] Intersection projects in the construction of urban roads, various highways, railways, etc., in the current form of intercommunication, mainly adopt the main form of plane intersection and three-dimensional intersection. The roads and bridges required for plane intersections and three-dimensional intersections occupy a large area of ​​open space. The three-dimensional intersection is a variety of interconnecting bridge structures, such as overpasses, and the project volume is relatively large. In order to save land resources and reduce engineering investment, the underpass structure using the underground space has become an important choice to form the form of intercommunication. [0003] The current construction of the underpass s...
