In order to connect fixedly, be convenient for installation and dismantlement simultaneously, be fixed with a plurality of fixed pipes respectively on the both sides limit of backup pad 5, fixed pipe on one of them backup pad 5 dodges the fixed pipe setting on two adjacent backup pads 5. During actual installation, the supporting plate 5 at the lowest layer is placed firstly, then the two side supporting plates 5 are connected respectively, the fixing sleeves on the two supporting plates 5 are butted, and are connected and fixed through the connecting rod 6, and the supporting plate 5 at the topmost layer is connected finally. After the four support plates 5 are connected, a stable quadrilateral structure is formed. The support plate 5 located at the bottom mainly plays a role of supporting, and the support plates 5 located at the two sides and the top are used for reserving a space for pouring the preset concrete 2, so that the measurement is not needed, and the thickness of the concrete 2 finally cured along the circumferential direction of the culvert 1 can be guaranteed to be consistent. The thickness of final concrete 2 can be determined according to the length of the supporting rod 3 and the thickness of the quick lattice cushion 4, measurement is not needed, construction is convenient, and efficiency is high.
As a specific embodiment of the method for repairing a large-section dark culvert provided by the present invention, please refer to fig. 5, the step of connecting and fixing two side edges of two adjacent rapid lattice mats 4 along the length direction of the dark culvert 1 comprises:
placing an annular gasket 10 between two adjacent quick lattice pads 4, and enabling the peripheral surface of the annular gasket 10 to be attached to the hidden culvert 1; two adjacent sides of the two speed check pads 4 are connected to the inner peripheral surface of the annular gasket 10.
In this application, if make the interior holistic cavity that forms of fast check pad 4, though seem simple and convenient, the resistance that pouring end concrete 2 flows is great when pouring concrete 2, finally leads to concrete 2 to be difficult to flow to the other end by one end, has the production of the incomplete phenomenon of pouring simultaneously. For this reason set up a plurality of fast check pads 4 to need to connect fixedly between two adjacent fast check pads 4, in order to make fast check pad 4 and dark culvert between form solitary casting cavity, be provided with annular packing ring 10 at the inboard of two adjacent sides of two adjacent fast check pads 4. The annular gasket 10 is arranged along the circumference of the culvert 1. Firstly, the outer side surface of the annular gasket 10 is attached to the inner wall of the hidden culvert 1, and the inner side surface of the annular gasket 10 is respectively used for being connected and fixed with the side edges of the two fast grid pads 4, so that plugging is realized.
As a specific embodiment of the method for repairing a large-section dark culvert provided by the present invention, referring to fig. 5, connecting two adjacent side edges of two fast check pads 4 to the inner circumferential surface of an annular gasket 10 includes:
the two adjacent side edges of the two quick lattice cushions 4 are cut and aligned, and the quick lattice cushions 4 and the annular gaskets 10 are connected and fixed through a plurality of expansion bolts 9 fixed on the inner wall of the hidden culvert 1.
In this application, after two adjacent fast check pads 4 fix a position, two adjacent fast check pads 4's both sides limit overlap joint each other to be convenient for subsequent tailor and processing. After aligning both side edges of the two speed check pads 4, a ring-shaped gasket 10 is placed on the inner side. After placing the ring gasket 10, the hole is drilled by a drilling machine and until it is drilled into the culvert 1. An expansion bolt 9 is placed in each bore hole and positioning is accomplished by tightening the bolt. The pressing plate can be connected to the end of the expansion bolt 9, the quick lattice cushion 4 is pressed tightly through the pressing plate, and the tightness of the annular gasket 10 and the hidden culvert 1 is guaranteed.
Referring to fig. 5, as a specific embodiment of the method for repairing a large-section culvert provided by the present invention, the step of connecting and fixing the lattice mat 4 and the annular washer 10 by the plurality of expansion bolts 9 fixed on the inner wall of the culvert 1 includes:
a plurality of fixing holes penetrating into the hidden culvert 1 are drilled at intervals along the length direction of the annular gasket 10, expansion bolts 9 are correspondingly placed in the fixing holes, and nuts at the end parts of the expansion bolts 9 are rotated to enable the quick lattice cushion 4 to be tightly pressed on the annular gasket 10.
In the application, after the annular gaskets 10 are placed in two adjacent quick lattice pads 4, holes need to be drilled from the inner side surfaces of the quick lattice pads 4 into the hidden culvert 1 through a drilling machine, and the drilled fixing holes need to have certain reserved lengths. After the drilling is completed, the expansion bolt 9 is inserted into the fixing hole after the expansion bolt 9 is positioned in the fixing hole. The pressing plate is connected to the top of the expansion bolt 9, the nut above the pressing plate is screwed down, the pressing plate compresses the quick lattice cushion 4, and finally the annular gasket 10 is tightly attached to the inner wall of the culvert 1.
In this application, when dark culvert 1 wall thickness is lower to and dark culvert 1 is interior to be carried the medium corrosivity lower, and the velocity of flow is when slower simultaneously. The outer circumferential surface of the annular gasket 10 can be coated with industrial glue for adhering and fixing the annular gasket 10 on the inner wall of the culvert 1, and the annular gasket 10 is fixed through the industrial glue, so that the whole construction efficiency is improved.
As a specific embodiment of the method for repairing a large-section dark culvert provided by the present invention, please refer to fig. 4, the supporting plate 5 is disassembled; the inner side surface of the quick lattice mat 4 is coated with a corrosion-proof material, and the positioning holes are plugged by the corrosion-proof material, and the method comprises the following steps:
