Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] see figure 1 , The prefabricated reinforced concrete splayed wall type culvert opening of the preferred embodiment of the present invention includes wing walls (splayed walls) arranged on both sides of the culvert entrance and exit.

[0031] Please refer to figure 2 and image 3 , the wing walls on each side include multiple prefabricated buttress-type reinforced concrete retaining walls 1 on the inside and prefabricated cantilever-type reinforced concrete retaining walls 2 on the outside, multiple prefabricated buttress-type reinforced concrete retaining walls 1 and prefabricated cantilever walls Reinforced concrete retaining wall 2 is combined and assembled sequentially from the opening outward to both sides to form wing walls. The number of prefabricated buttress-type reinforced concrete retaining walls 1 is jointly dete...

Abstract

The invention discloses an assembly-type reinforced concrete splay wall-type inlet and outlet of a culvert. The assembly-type reinforced concrete splay wall-type inlet and outlet of the culvert comprises wing walls arranged on both sides of the inlet and outlet of the culvert. Each side of the wing wall comprises a precast counterfort reinforced concrete retaining wall and a precast cantilever reinforced concrete retaining wall, and a plurality of precast counterfort reinforced concrete retaining walls and precast cantilever reinforced concrete retaining walls are combined and assembled one by one from the inlet and outlet outward to both sides. The precast counterfort reinforced concrete retaining wall is precast of vertical walls, vertical wall heel slabs, vertical wall toe boards and a counterfort. The precast cantilever reinforced concrete retaining wall is precast of the vertical walls, the vertical wall heel slabs and the vertical wall toe boards. The back of the vertical walls, near the side edge, are provided with pre-embedded bolts. The two vertical walls are connected and assembled by inter-segment connection steel plates, and each inter-segment connection steel plate is fixed through the pre-embedded bolts. The invention also discloses a construction method for assembly-type reinforced concrete splay wall-type inlet and outlet of the culvert. The assembly-type reinforced concrete splay wall-type inlet and outlet of the culvert adopts prefabricated components to realize assembly connection, thereby improving the project quality, shortening the construction period and reducing the project cost.

Description

technical field [0001] The invention relates to the field of culvert and channel structure engineering, in particular to a prefabricated reinforced concrete splayed wall-shaped culvert opening and a construction method. Background technique [0002] The opening types of highway culverts and passages in my country mainly include straight wall type and wing wall type. The straight wall type is mainly used in passages for passing vehicles, tunnels and artificial narrow channels and culverts. Wing wall types include splayed wall type, straight wall type, tapered slope type, etc. Among them, splayed wall type wing wall is the most widely used, suitable for access culverts under various water conservancy conditions, and is the most common form of highway culvert openings. [0003] At present, the existing conventional splayed walls are all gravity-type structures cast on site. Due to the point distribution of the channel structure, the cast-in-site method has disadvantages such a...
