Description

Technical Field

[0001] The present invention relates to the technical field of municipal pipelines, and provides a fixing device and an installation method for a horizontal drain hole of a shoulder wall under a municipal road Background Art

[0002] In recent years, with the continuous improvement of China's urbanization rate, the urban area has been continuously expanding towards the surrounding areas, making the original expressways on the outskirts of the city gradually embraced by the city. In order to better develop the economy of the cities on both sides of the expressway, the criss-crossing urban roads have to cross the existing expressway to open up the traffic between the areas on both sides of the expressway. The common forms of the intersection of municipal roads and expressways are overpassing and underpassing. Under the same conditions, the underpassing scheme is often favored by the construction unit for its economic advantage that the cost is less than 25% of the overpassing scheme. The underpassing scheme often adopts the road and bridge scheme with low construction difficulty, low construction risk and fast construction speed, that is, the original expressway subgrade is changed into a bridge, the fill in the subgrade section is removed, and the municipal road passes under the bridge to form a separated interchange.

[0003] For the original expressway road-to-bridge transformation, the underpassing municipal road passes through from below. Due to the relatively high original ground elevation on both sides and the relatively low terrain in the underpassing part, a section of cutting is formed. Usually, the municipal road designer will set shoulder walls in the underpassing section to block the soil on both sides, fix vegetation, etc., to ensure the quality and service life of the underpassing municipal road. Below the inner part of the shoulder wall, horizontal drain holes are usually also set to drain the interstitial water on both sides of the cutting. How to effectively control the elevation and slope of the pre-buried horizontal drain holes, ensure that the drain holes are not damaged during concrete pouring, and ensure beauty after forming has become a difficult problem to be solved urgently. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: how to conveniently install the drain pipe in the poured shoulder wall to ensure that the drain pipe will not be damaged due to pouring.

[0005] To solve the above technical problem, the inventor has obtained the technical solution of the present invention through practice and summary.

[0015] A method for installing a fixing device for a transverse drainage hole of a shoulder wall of a municipal road, comprising the following steps:

[0016] Step 1: Before pouring the shoulder wall, install the side wall formwork on one side. After installation and firm fixation, use a handheld laser level to pop up the elevation control line inside the embedded horizontal drain hole according to the elevation design in the construction drawing, and fix the corresponding closure on the inner side of the installed side wall formwork with screws.

[0017] Step 2: After the steel bars to be poured inside are tied up, measure the elevation line outside the embedded drain hole on the other side of the side wall formwork, and fix the other closure on the outer formwork with screws.

[0018] Step 3: Before closing the formwork, install the fixing column on the mounting plate and thread it in the middle of the positioning plate. The fixing column extends outward beyond the side wall formwork; the two groups of side wall formworks are symmetrically installed, and the positions of the drain holes on both sides correspond.

After the two groups of side wall formworks are aligned and closed, alignment installation can be achieved, and the blocking effect can also be achieved.

[0023] In the present invention, one end of the rotating handle is installed to slide in the annular groove. By disassembling and assembling the rotating handle, the rotating handle drives the rotation of the fixing column, and then the disassembly and assembly of the mounting plate on the positioning plate are realized, and the space inside the drain pipe is connected, that is, both ends of the drain pipe are no longer blocked.
