Description

Technical Field

[0001] The present invention relates to the technical field of subway tunnel segment or lining repair, and more particularly to the technical field of a flexible composite cavity installation machine and a use method. Background Art

[0002] The subway tunnel segments are complete rings of subway tunnel concrete linings assembled from prefabricated segments at the back of the shield machine as it digs forward. These segments are the innermost barrier of the subway tunnel, responsible for resisting soil pressure, groundwater pressure and some special loads.

[0003] After being put into use for a period of time, subway tunnel segments may develop cracks, falling off, and other damage. It is necessary to repair the damaged parts or local subway tunnel segments in a timely manner to ensure the normal operation of the subway transportation system.

[0004] When using the flexible composite cavity repair method to repair subway tunnel segments, how to quickly and accurately deploy the flexible composite cavity at the location to be repaired and quickly carry out the repair work is particularly important for the repair work of the subway tunnel segments. Summary of the Invention

[0005] The purpose of the present invention is to solve the above technical problems and provide a flexible composite cavity installation machine and a method of use.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A flexible composite cavity installation machine includes a power lifting assembly, a detachable spanner, a base and a support and deployment rod. The base provides support and fixation for the power lifting assembly, the detachable spanner and the support and deployment rod. The power lifting assembly and the support and deployment rod are respectively arranged on the top of the base, and the detachable spanner is arranged at the top of the lifting assembly.

[0008] Furthermore, the lifting assembly consists of a flexible chain, a connecting rod and two rotating wheels. The connecting rod is arranged between the two rotating wheels and is rotationally connected to the two rotating wheels respectively. The flexible chain is meshed and connected to the two rotating wheels.

[0009] Furthermore, the flexible chain is movably connected to the flexible composite cavity to prevent the flexible chain and the flexible composite cavity from sliding against each other during the lifting process. The connection between the flexible chain and the flexible composite cavity is not less than 1 / 2 of the total length of the flexible composite cavity, which facilitates the expansion of the flexible composite cavity on the opposite side of the obstacle.

[0010] Furthermore, the movable connection is in the form of Velcro or zipper.

[0011] Furthermore, one of the two rotating wheels is connected to a driving assembly or a rotating part for manual driving.

[0012] Furthermore, the driving component is a motor.

[0013] Furthermore, the disengagement spanner is composed of a limit guide part, a disengagement part, a spanning part and a support part. The bottom end of the support part is connected to the connecting rod, and a limit guide part is provided at the top of the support part. The disengagement part is provided on one side below the limit guide part and the spanning part is provided on the other side. The limit guide part can prevent the flexible composite cavity from tilting sideways during the outward expansion process, and ensure that the flexible composite cavity is formed in the plane; the disengagement part can disengage the flexible chain from the flexible composite cavity; the spanning part can guide the flexible composite cavity after being disengaged from the flexible chain to cross obstacles, such as cables, etc., and has a "U"-shaped structure to prevent the flexible composite cavity from radially rotating or moving during the sliding process. The support part provides reliable and stable support for connecting the disengagement part, the spanning part and the flexible composite cavity.

[0014] Furthermore, at least two supporting and unfolding rods are provided, which guide the flexible composite cavity to pass through the obstacles on both sides after the flexible composite cavity crosses the obstacle. After the position of the flexible composite cavity is determined, the flexible composite cavity is supported and initially formed.

[0015] Furthermore, a socket is provided on the top of the base, and the bottom end of the support and expansion rod is plugged into the socket to fix the support and expansion rod to prevent the flexible composite cavity from tilting or sliding when it is expanded.

[0016] Another inventive object of the present invention is to provide a method for using the above-mentioned flexible composite cavity installation machine, including the following steps: first, moving the flexible composite cavity installation machine to the location where the subway tunnel segment is to be repaired, then connecting one end of the flexible composite cavity to the flexible chain of the power lifting assembly, starting the driving assembly or manually rotating the rotating part to lift the flexible composite cavity to the top of the lifting assembly, and then using the disconnector to separate the flexible composite cavity from the flexible chain, and guiding the flexible composite cavity to cross the cable on the top of the subway tunnel segment, and then as the flexible composite cavity falls, the flexible composite cavity is guided through the cables on both sides by the support expansion rod, and then the top end of the support expansion rod is used to support the flexible composite cavity, and the bottom end of the support expansion rod is inserted into the socket at the top of the base to complete the initial forming of the flexible membrane.

[0017] The beneficial effects of the present invention are as follows:

[0018] The present invention provides a flexible composite cavity installation machine and a method of use, which can quickly pass the flexible composite cavity through obstacles such as cables in subway pipe segments, ensure that the flexible composite cavity completes spatial positioning according to design requirements, and forms the initial shaping of the flexible membrane. It has the advantages of high construction efficiency, light equipment weight, and convenience for construction in narrow spaces. BRIEF DESCRIPTION OF THE DRAWINGS
