Description

Technical Field

[0001] The utility model relates to a pre-buried casing construction auxiliary tool, in particular to a segment pre-buried casing auxiliary installation device. Background Art

[0002] The traditional installation of embedded casing for pipe segments generally includes the following steps: Preparation: Determine the location and number of casings and arrange them according to design requirements. Clean the surrounding environment of the embedded casing location, ensure that the construction area is clean, and remove obstacles that may affect the installation of the casing. Casing installation: Before pouring concrete, reserve holes for embedded casings on the template corresponding to the embedded casing positions, then insert the casing into the holes, and adjust and position them according to design requirements to ensure that the position and angle of the casing and the pipe segment meet the requirements. Fixing the casing: After the casing is installed, it is usually necessary to use a support frame or other fixing equipment to fix the casing in the predetermined position. This ensures that the casing will not shift or tilt during the concrete pouring process. Concrete pouring: After the casing is installed and fixed, pour the concrete around the pipe segment. During the pouring process, ensure that the concrete fully fills the space around the casing, and use tools such as vibrators to compact it to ensure the uniformity and density of the concrete. During the traditional casing installation operation, workers directly screw the embedded casing onto the screw rod by hand; this installation method has the following defects: direct manual screwing is difficult to operate and the construction efficiency is low.
