Track flat-opening inspection well mold

Abstract

The invention relates to a track flat-opening inspection well mold, and belongs to the technical field of building material production equipment. The inspection well mold comprises a base plate, a cylindrical outer shell and a core body, wherein the diameter of the core body is smaller than that of the outer shell, the core body is coaxially located in the outer shell, the core body and the outer shell are arranged on the base plate, and the core body comprises a center column; a front butt joint plate and a rear butt joint plate are symmetrically arranged at the front side and the rear side of the center column, a left butt joint plate and a right butt joint plate are symmetrically arranged at the left side and the right side of the center column, the front butt joint plate, the rear butt joint plate, the left butt joint plate and the right butt joint plate are all arc-shaped plate surfaces and are in butt joint to form a cylindrical core body shell, and the four butt joint plates are connected with the center column through corresponding connecting rods; and a lifting device is arranged at the bottom of the center column. The core body shell of a core body of the track flat-opening inspection well mold can be driven by the center column to retract inwards, so that the core body shell is separated from the inner wall of a solidified inspection well pipeline, the friction force is reduced, and the inspection well pipeline can be conveniently taken out of the mold.

Description

technical field [0001] The invention relates to the technical field of building material production equipment, in particular to a rail flat opening inspection well mold. Background technique [0002] The production of existing inspection wells and other cylindrical concrete pipelines is basically cast by using molds. Most of the existing pipeline casting molds are composed of two coaxial cylindrical shells. A circular columnar space is formed. For the convenience of operation, the outer casing is mostly assembled with arc-shaped plates. After the poured concrete is solidified, the outer casing is opened, and the inner casing is pulled out from the pipe to complete the production of the concrete pipe. However, since the concrete is directly poured on the inner casing during the pipeline manufacturing process, the pipeline is in close contact with the inner casing after solidification, and the friction force is huge, so it is difficult to separate the two, and the concrete pip...

Problems solved by technology

However, since the concrete is directly poured on the inner casing during the pipeline manufacturing process, the pipeline will be in close contact with the inner casing after solidification, and the friction force is huge, so it is difficult to separate the two, and the concrete pipeline is often damaged during the separation process.
