Description

Technical Field

[0001] This invention belongs to the field of concrete construction, specifically relating to a reverse rapid pouring trolley for arch wall concrete. Background Technology

[0002] In tunnel construction, secondary lining is a crucial process for ensuring the safety and durability of the tunnel structure. Traditional lining trolleys use a "arch first, sidewalls follow" pouring sequence. After the arch concrete is poured, the sidewalls are poured before initial setting. At this time, cold joints are prone to form at the junction of the arch and the walls. The seepage resistance pressure at the cold joints is lower than that of the integrally poured parts, resulting in water seepage under high water head conditions. The cost of grouting and sealing leaks later is high. For tunnels with large spans, the arch concrete settles due to its own weight, and gaps are prone to appear at the junction with the sidewalls, becoming weak points in the structure.

[0003] Reverse concrete pouring effectively solves the above problems. Reverse concrete pouring refers to pouring in the opposite direction to the tunnel boring machine's (TBM) forward movement: workers start pouring from the very front of the TBM (facing the unexcavated face) and then gradually reverse towards the rear (closer to the completed section). The direction of the pouring operation is opposite to the direction the TBM will move next. In conventional forward pouring, the endpoint (construction joint) of each pour is located at the top or upper side of the tunnel cross-section. This location is a "dead zone" in concrete pouring, prone to air bubble accumulation, bleeding, etc., leading to loose joints, low strength, and even future leaks. In reverse pouring, however, the endpoint (construction joint) of each pour is located at the bottom of the tunnel cross-section. The bottom is the easiest part of the concrete to pour and vibrate to achieve compaction. When new concrete combines with the construction joint at the bottom of the previous cycle, it ensures a very dense and strong joint, greatly reducing the risk of leakage and improving the overall structural quality and durability. Therefore, reverse pouring of concrete is a standard practice commonly used in underground engineering projects with high-quality requirements.

[0004] However, the pouring efficiency, construction quality, and adaptability to working conditions of the arch wall concrete reverse pouring trolley provided in the existing technology need to be improved. Summary of the Invention

[0013] In one specific embodiment, one end of the feeder (306) is rotatably connected to a feed pipe (307), and one end of the feed pipe (307) is equipped with an injection head (308) through a corrugated hose.

One end of the electric telescopic rod (317) is fixedly connected to one end of the injection head (308). The electric telescopic rod (317) is used to push the injection head (308) to complete the insertion with the first connector (310) and the second connector (312).

The pouring mechanism uses a tracked trolley, a rotatable feeding pipe, and infrared positioning to achieve precise docking and branched material supply, realizing reverse pouring and integrated concrete molding. Automated operation reduces manual intervention and improves construction safety and the density of the arch wall concrete. Attached Figure Description

[0033] The first mounting cylinder 204 and the second mounting cylinder 201 are respectively connected to the first pouring port 209 and the second pouring port 208 to provide a guiding channel for concrete pouring, avoid concrete overflow, and facilitate precise matching with the joint of the pouring mechanism 3 to improve the sealing of the pouring.

At this time, the third hydraulic rod 213 drives the first stop block 202 and the second... The two abutment blocks 205 are separated from the first pouring port 209 and the second pouring port 208 respectively. Concrete is fed into the first installation cylinder 204 and the second installation cylinder 201 through the feeding pipe 307, the first connecting pipe 203 and the second connecting pipe 210. It is injected into the template through the first pouring port 209 and the second pouring port 208. The vibration motor 211 vibrates in layers. During pouring, it is poured from bottom to top from the bottom of the side formwork 207. As the concrete height increases, the first pouring port 209 at the corresponding position is driven by the third hydraulic rod 213, causing the first abutment block 202 to reset and block the first pouring port. After the side pouring is completed, the arch part is poured, realizing reverse rapid integrated pouring.
