Abstract

The invention belongs to the technical field of shield grouting materials, and provides a shield grouting material, a preparation method thereof and a shield grouting material preparation device in order to solve the problems that in the preparation process of an existing shield grouting material, the raw material consumption error is large, and manpower and time are consumed doubly. The bottom ofa batching box is fixedly connected with a conveying cavity; a conveying pipe penetrates through the bottom surface of the batching box; the top end of the conveying pipe is connected with a receiving hopper; a hollow inner cavity is formed in the batching box body, an electric rotating device is installed at the bottom in the hollow inner cavity, a plurality of through holes are formed in the bottom surface of the electric rotating device at intervals, and batching areas are movably connected to the through holes; the overall performance of the filler is fully released by utilizing premixingtime, after the filler is added into the main body material, the filler is matched with an additive to form a stable permeation state, the filler can be rapidly diffused into the main body material,and the overall performance of the grouting material is improved; the discharging stability of the device is improved while the human resource input is reduced, and the overall use experience and theworking efficiency of the device are ensured.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling grouting materials, and in particular relates to a shield tunneling grouting material, a preparation method thereof, and a shield tunneling grouting material preparation device. Background technique [0002] Subway shield tunneling is an important construction technology in urban subway construction. It is a construction method for digging underground tunnels under the ground. While the surface is stable, tunnel excavation and lining operations can be carried out safely inside the machine. During the construction process, a shaft or foundation pit must be excavated at one end of a certain section of the tunnel, and the subway shield machine should be hoisted into the installation. The subway shield machine Excavation starts at the opening in the wall of a shaft or excavation and advances along the line of the hole until it reaches the end of another shaft or tunnel in the line of the hole...
