Abstract

The invention discloses an ultra-high performance concrete prefabricated assembly comprehensive pipe rack. The comprehensive pipe rack comprises a comprehensive pipe rack segment and a horizontal bearing and inserting structure, the comprehensive pipe rack segment is subjected to head and tail sequential connection in the longitudinal direction of the pipe rack in the horizontal direction, the comprehensive pipe rack segments are assembled and connected through the horizontal bearing and inserting structure, the horizontal bearing and inserting structure comprises a bearing opening formed in apipe opening in the front end of the comprehensive pipe rack segment and an inserting opening formed in a pipe opening in the rear end of the comprehensive pipe rack segment, the bearing opening is arranged as an annular groove corresponding to the pipe opening along the pipe opening in the front end of the comprehensive pipe rack segment, and the inserting opening is arranged as an annular bosscorresponding to the pipe opening along the pipe opening in the rear end of the comprehensive pipe rack segment. The inserting opening is inserted into the bearing opening to enable the two adjacent comprehensive pipe rack segments to be assembled and connected. The comprehensive pipe rack is convenient to assemble and transport, high in assembly precision, and good in assembly seam waterproof effect.

Description

technical field

[0001] The invention belongs to the technical field of urban underground comprehensive pipe gallery, in particular to an ultra-high performance concrete prefabricated and assembled comprehensive pipe gallery. Background technique

[0002] There are two types of existing integrated pipe gallery structures: cast-in-place ordinary reinforced concrete and overall prefabricated ordinary reinforced concrete. The aggregate of ordinary concrete is relatively large, the material performance and durability are average, and the material performance is relatively low, which requires a large structure volume and heavy structure weight. The cast-in-place ordinary reinforced concrete pipe gallery has difficulties in construction, heavy workload, long period, great influence on site conditions, poor concrete self-waterproof ability and needs outsourcing waterproofing, etc. It is difficult to control the quality and accuracy of the construction process; the overall prefabrica...
