Description

Technical Field

[0001] This utility model relates to the field of tunnel pouring construction technology, specifically to a periscope-type pouring device. Background Technology

[0002] The construction of the tunnel arch is a crucial step in tunnel engineering, involving a series of processes such as concrete preparation, transportation, pouring, vibration, and curing. During the pouring process, it is essential to ensure that the concrete evenly covers the entire arch area.

[0003] Currently, the main methods in China are as follows:

[0004] (1) The current method employs direct-pump and inclined-pump casting techniques, where a lining trolley equipped with a placing unit pumps concrete from a pump truck into a grouted arch through four grouting holes. The concrete is then poured from the completed lining end towards the end until the lining is fully filled. However, pouring from the bottom up creates an air-stopping wall effect, preventing air from escaping and forming cavities (voids), which in turn leads to low concrete strength and eventual spalling. Current methods use additional grouting to address this issue, wasting significant manpower and resources.

[0005] (2) The arch pouring port with its own telescopic rotation is used for pouring. This structure often uses a self-contained hydraulic cylinder to telescopically extend and retract the pouring port. However, using a hydraulic cylinder has drawbacks. If the installation distance is too large, the torque on the pouring port during rotation will be too high, which may cause problems such as hydraulic cylinder leakage or damage. In addition, if the installation distance is too large, the installation space may be insufficient, which will result in higher requirements for the size of the secondary lining section and a limited range of applications. The telescopic movement of the pouring port with the self-contained hydraulic cylinder and the telescopic movement of the concrete placing system are two separate systems. When used in combination, it is difficult to ensure the synchronization of the telescopic hydraulic cylinder of the pouring port and the telescopic hydraulic cylinder of the concrete placing system, which makes the operation complicated.

[0006] In summary, there is an urgent need for a casting device with a simplified structure, small installation space, and compatibility with existing concrete placement systems to solve the problems existing in the prior art. Utility Model Content
