Abstract

The invention discloses a pipe jacking mold facilitating demolding of inner mold. The pipe jacking mold comprises a base, and an outer mold and the inner mold are arranged on the base. The inner mold is composed of four concentric arc-shaped plates, every two arc-shaped plates are in circle center symmetry, and the two symmetrical sets of the arc-shaped plates are sequentially shrunk for demolding front and back. Connecting rods are fixed to the middles of the inner sides of the arc-shaped plates. The pipe jacking mold is characterized in that a rotary inner mold collecting device connected with the connecting rods is arranged in the center of the inner mold, and locking devices are arranged at the joints of the arc-shaped plates. The pipe jacking mold can be qualified for production of pipe jacking and is beneficial to demolding of the inner mold.

Description

technical field [0001] The invention relates to a pipe jacking mold which is convenient for demoulding of an inner mold, and belongs to the field of pipe jacking production tools. Background technique [0002] Pipe jacking construction is a non-excavation construction method, and it is a pipeline burying construction technology that does not excavate or excavates less. In the working pit, with the help of the jacking force generated by the jacking equipment, the friction between the pipeline and the surrounding soil is overcome, the pipeline is pushed into the soil according to the designed slope, and the earth is transported away. With the development of infrastructure, more and more existing jacking pipes are used. [0003] During the production process of the pipe jacking, the inner mold and the outer mold are used for prefabrication. During the production process, it was found that the demoulding of the inner mold is extremely difficult and cumbersome in the existing pr...
