Description
Technical Field
The invention relates to tunnel construction, in particular to a prefabricated culvert structure.
Background
The culvert is a drainage channel which is arranged below a roadbed and built below a road surface in order to ensure that a road smoothly passes through a water channel and does not obstruct traffic in the construction of road engineering. The culvert is built through cast-in-place, but the control difficulty of cast-in-place manufacturing is high, so that the construction stability is low, the construction quality fluctuation is large, the construction period is long, and the construction cost is high.
Disclosure of Invention
The present invention is directed to provide a structure for constructing a culvert through prefabricated members, so as to improve the efficiency, quality and stability of culvert construction and reduce the difficulty and cost of construction.
The culvert structure comprises a top plate, side walls and a bottom plate, wherein the top plate and the side walls are prefabricated, and the bottom plate is cast in situ; the side walls are vertically arranged on two sides of the culvert respectively, the top plate is transversely arranged on the top of the culvert, two ends of the top plate respectively abut against the tops of the side walls, and the bottom plate is arranged between the bottoms of the two side walls.
In the culvert structure, two ends of the top plate extend downwards to form extension plates, and the bottoms of the extension plates are abutted against the tops of the side walls; the bottom of the side wall is provided with supporting legs extending towards two sides, and the bottom plate is arranged between the supporting legs at the two sides.
The culvert structure is characterized in that two prefabricated side wall components are arranged on two sides of a culvert; secondly, mounting the prefabricated top plate component to the top of the culvert, and enabling the extension plates at the two ends of the top plate to be abutted against the tops of the side walls; after the top plate and the side wall are positioned, casting in situ to manufacture a bottom plate; and then, connecting the gap between the bottom of the extension plate and the top of the side wall so as to fixedly connect the top plate and the side wall.
According to the culvert structure, the top plate and the side walls are manufactured into prefabricated components in a prefabricated mode in a factory, when the culvert is constructed, the prefabricated components are transported to a construction site, then the side walls are erected to be used as supports, the top plate is hoisted to the tops of the side walls, then after the top plate and the side walls are positioned, the bottom plate is manufactured in a cast-in-place mode, after the bottom plate is manufactured, gaps such as hinge joints, seams, settlement joints and the like between the top plate and the side walls are constructed, and finally, construction of auxiliary projects such as holes, splayed walls and the like is carried out according to a general culvert construction method, so that the construction of the culvert is completed. By prefabricating the structural member, the quality of the structural member can be more accurately controlled, the manufacturing stability of the structural member is improved, the cost is reduced, the influence on the construction site of the culvert is avoided, and the construction efficiency is also improved; especially for the culvert with large length and large number of channels, the quality and the construction stability of the culvert can be greatly improved through the manufacture of the prefabricated member, and the construction period is effectively shortened.

Detailed Description
A culvert structure comprises a top plate 1 and side walls 2 which are prefabricated, and a bottom plate 3 which is cast in situ; the side walls are vertically arranged on two sides of the culvert respectively, the top plate is transversely arranged on the top of the culvert, two ends of the top plate respectively abut against the tops of the side walls, and the bottom plate is arranged between the bottoms of the two side walls.
In the culvert structure, two ends of the top plate 1 extend downwards to form extension plates 4, the bottoms of the extension plates are abutted against the tops of the side walls 2, and the structural strength of the top plate is improved through the extension plates; meanwhile, the top plate 1 is in chamfer transition connection with the extension plate 4, the extension plate is short in length, or the end part of the top plate can be chamfered and bent, so that the overall structural strength of the top plate is further improved. In addition, the bottom of the extension plate 4 and the top of the side wall 2 are respectively provided with an outward convex boss and an inward concave boss which are matched with each other, so that the positioning during installation construction is assisted, and the connection strength between the bosses and the concave bosses can also be improved.
The culvert structure, the bottom of side wall 2 is the supporting legs 5 that extend to both sides, and bottom plate 3 sets up between the supporting legs of both sides, both can improve the structural strength of side wall component, also can improve its stability of placing and supporting, can also improve the preparation convenience of bottom plate, and improve the connection stability that bottom plate and side wall bottom are connected. In addition, the top plate 1 and the side walls 2 are both provided with hanging rings (not shown) so as to be convenient for matching transportation and installation construction.
A culvert construction process comprises the following steps:
1) mounting two prefabricated side wall components on two sides of the culvert;
2) mounting the prefabricated top plate component to the top of the culvert, and enabling the extension plates at the two ends of the top plate to abut against the tops of the side walls;
3) after the top plate and the side wall are positioned, casting in situ to manufacture a bottom plate;
4) and connecting and constructing a gap between the bottom of the extension plate and the top of the side wall so as to fixedly connect the top plate and the side wall.
According to the culvert construction process, before the side walls are installed, foundation pits required for side wall installation and bottom plate pouring are firstly excavated in the culvert, so that the ground is better processed, the accuracy of side wall installation is improved, and the required bottom plate is poured more conveniently and accurately.
In the culvert construction process, before the top plate and the side wall are installed, measurement lofting is firstly carried out, namely measurement is carried out on a foundation, and hoisting positions required by the top plate and the side wall are marked; when the side wall is hoisted, the side wall moves in place along the horizontal direction, then is hoisted vertically, the slope, the flatness and the expansion joint of the flowing water surface of the side wall are adjusted after the side wall is hoisted in place, then the side wall is fixed, after the side wall is fixed, the hoisting rings on the side wall are cut off, and then the top plate is hoisted to the side wall, so that the hoisting rings are prevented from influencing the installation of the top plate.
