A Setting Method of Deformation Joint Obliquely Intersecting with Underground Box Culvert

Abstract

The invention discloses a setting method for a deformation joint obliquely crossed with an underground box culvert. The deformation joint is obliquely crossed with the central axis of the underground box culvert. The setting method is characterized by comprising the following step: arranging a convex reinforced concrete adjusting block at the position of the deformation joint of the underground box culvert so as to enable an externally bonded or buried water stop to be continuously, smoothly and annularly arranged around the underground box culvert. The setting method disclosed by the invention has the advantages that under a certain special environment condition, the underground box culvert requires to be provided with the deformation joint obliquely crossed with the underground box culvert, and especially under the small-included angle oblique crossing condition, by adopting the setting method, the externally bonded water stop and the buried water stop which are arranged so as to meet the water-proof need of the underground box culvert can continuously surround the box culvert, and do not need to be reconnected after being cut off, and therefore the problem that tooth sockets in the externally bonded water stop and the buried water stop at the corners of the box culvert are discontinuous is overcome; meanwhile, the processes of cutting off and reconnecting the water stops are also omitted, and meanwhile, the box culvert has a better water-proof effect.

Description

technical field [0001] The invention belongs to the technical field of underground box culverts, and in particular relates to a method for setting deformation joints obliquely intersecting with underground box culverts. Background technique [0002] The buildings on both sides of the road in a plot in Shanghai Hongqiao are equipped with underground garages. The underground garages on both sides of the road are required to be connected by underground passages, and the connection ports reserved for the garages on both sides can only be in the form of connecting passages arranged obliquely. When the structures are connected, deformation joints should be set and the deformation joints must be set in the range of the underground passage near the underground garage. Under this condition, if the method of setting deformation joints perpendicular to the underground garage is adopted, the structure on the side adjacent to the underground garage and the connecting passage will protrud...

AI Technical Summary

Problems solved by technology

Under this condition, if the method of setting deformation joints perpendicular to the underground garage is adopted, the structure on the side adjacent to the underground garage and the connecting passage will protrude longer, and the structure on the other side will protrude shorter, and the ground road vehicles will inevitably span For the oblique connecting channel buried under the road and with shallow covering soil, it is not ideal to set such a joint under the condition of vehicle live load, especially the intersection between the garages on both sides and the connecting channel at a small angle is more unfavorable

It is reasonable to consider the setting of deformation joints parallel to the garages on both sides and oblique to the connecting passage. The corners of the side walls of the culvert and the top and bottom plates cannot be turned continuously, and the waterstops must be cut and then manually connected. Since the deformation joints are obliquely intersected with the box culvert, they must be installed after the top and bottom waterstops and the side wall waterstops are cut. The incision lengths are different, so that after the waterstop is manually connected, the waterstop is attached to the inner side of the waterstop, and the alveolar grooves on both sides of the buried waterstop are still disconnected and discontinuous, resulting in poor waterstop effect at the corner of the box culvert
