The box culvert structure is a permanent structure, can be used for water conveying and drainage, and can also be used as an underground passage (space) and the like; if the box culvert structure is temporary building or other material structures like the steel construction, structural style still be suitable for, satisfy the structure atress during structural design can.
The parting structure comprises two parts, wherein one part is positioned between the cantilever bracket type structure and the pile type supporting structure, and the other part is positioned at the connecting interface of the pile type supporting structure and the side wall of the box culvert structure; in order to enable the whole stress deformation of the box culvert structure to be better coordinated, the supporting pile top connecting beams of the cantilever bracket type structure and the pile type supporting structure are directly supported, the box culvert structure and the pile type supporting structure are not directly bonded, and an asphalt layer is coated on a parting surface or a thinner caulking material layer is adopted for physical separation.
The utility model has the advantages that:
1. simple structure, safety and reliability. The cantilever bracket type structures are additionally arranged on the two sides of the box culvert structure, the pile type supporting structure is directly connected with the box culvert structure body in a supporting stress mode, and the structure is simple and clear in stress.
2. The pile type supporting structure is reused, and investment is saved. After the pile type supporting structure finishes the excavation supporting and retaining effect, the pile type supporting structure is combined with the foundation reinforcing mode of the box culvert structure body to jointly bear the vertical resistance of the box culvert structure, the body foundation treatment of the box culvert structure is reduced, and the overall engineering investment is saved.
3. Construction is convenient, saves the time limit for a project. The pile type supporting structure is used as a part of the deep foundation pit and is constructed in advance, so that the foundation reinforcement treatment period of the box culvert structure main body is shortened; the cantilever bracket type structure added can be constructed with the main box culvert structure at one time, and construction is convenient.
