Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] see figure 1 , the door-shaped assembled reinforced concrete box-shaped culvert of the preferred embodiment of the present invention comprises a prefabricated door-shaped reinforced concrete culvert 1 and a cast-in-place reinforced concrete floor 2, and the prefabricated door-shaped reinforced concrete culvert 1 is composed of several prefabricated door-shaped reinforced concrete components 3 assembled along the axial direction.

[0029] Please refer to figure 2 , the prefabricated door-shaped reinforced concrete member 3 has slightly different structures according to different positions, and can be divided into prefabricated door-shaped member front section 3.1, prefabricated door-shaped member middle section 3.2 and prefabricated door-shaped member rear section 3.3. The front section 3.1 of the prefabricated portal-shaped ...

Abstract

The invention discloses a door-shaped assembled reinforced concrete box culvert which is formed by pouring a prefabricated door type reinforced concrete culvert body and a cast-in-place reinforced concrete bottom plate, wherein the prefabricated door type reinforced concrete culvert body is formed by splicing a plurality of prefabricated door-shaped reinforced concrete members along the axial direction of the culvert; the prefabricated door-shaped reinforced concrete members are prefabricated into a whole by virtue of a top plate at the upper side, vertical walls at two sides and vertical wall heel slabs extending inwards from the lower edges of the vertical walls; suspension ring steel bars for hoisting are pre-buried on the upper surface of the top plate; reserved bolt holes are formed in the outside surfaces of the vertical walls; steel sleeves are pre-buried at the bolt holes of the vertical walls; and screw rods extruding out of the upper surface are pre-buried in the vertical wall heel slabs. The invention also discloses a construction method of the door-shaped assembled reinforced concrete box culvert. In the invention, the door-shaped reinforced concrete members are intensively prefabricated in factories, the prefabricated door-shaped reinforced concrete members are hoisted and spliced on the site, the construction operation is simple and easy, and the construction speed is high.

Description

technical field [0001] The invention relates to the field of channel structure engineering, in particular to a door-shaped assembled reinforced concrete box-shaped culvert and a construction method thereof. Background technique [0002] At present, most of the existing box-shaped culverts and passages adopt the construction method of pouring on site. Due to scattered construction sites and uneven construction levels, it is difficult to control the quality of the project. In addition, each construction step of pouring-in-place is a serial operation method, resulting in a longer construction period. [0003] Today's highways and urban roads have a huge traffic volume, and the construction of culverts and passages will inevitably affect road traffic. If the construction method of on-site pouring is used, it will take too long, and the existing prefabricated culvert structure has many blocks and poor integrity, and its scope of application is narrow. [0004] Therefore, it is...
