Shield Digging Safety and Fast Combination Light Pillow

Abstract

The invention relates to the field of construction of shield tunneling sleepers, in particular to a safe and rapid combined shield tunneling light sleeper. The safe and rapid combined shield tunneling light sleeper solves the problems that according to an existing light sleeper, installation needs great effort, rail disengagement occurs during operation, maintenance needs a long time, and disassembly needs a large amount of labor after construction. The safe and rapid combined shield tunneling light sleeper comprises transport cart box iron sleeper bodies and shield tunneling sleeper bodies, wherein the shield tunneling sleeper bodies are assembled together with the two ends of the transport cart box iron sleeper bodies. The two ends of each transport cart box iron sleeper body is each provided with a U-shaped groove, and transport cart rails are arranged in the U-shaped grooves in the two sides of each transport cart box iron sleeper body. Each shield tunneling sleeper body comprises arc steel plates and arc step sleeper bodies, wherein the arc steel plates are attached to a tunnel bottom segment and are identical in radian, and the arc step sleeper bodies are fixed to the high ends of the arc steel plates. The lower end of each arc steel plate is provided with a protruding portion which is inserted into the corresponding transport cart box iron sleeper body. Each arc step sleeper body is provided with a clamping groove formed by two opposite rail clamping locating plates. Shield tunneling rails are arranged in the rail clamping grooves. By the adoption of the safe and rapid combined shield tunneling light sleeper, the frequency of rail disengagement during operation is reduced, construction safety is guaranteed, and the situation that personnel are specially assigned to conduct maintenance is avoided; the safe and rapid combined shield tunneling light sleeper has the advantages that the technology is simple and advanced, and the practicability is high.

Description

technical field [0001] The invention relates to the field of shield tunneling construction, in particular to a safe and fast combined light sleeper for shield tunneling. Background technique [0002] my country's shield tunnels have begun to develop towards long distances and small curves. During shield tunneling, both the shield machine and the construction transport vehicles need sleepers. Traditional sleepers use pressure plates to fix the rails on the I-beam, and tie rods are used between the two rails. connection to ensure the track spacing, due to the long excavation distance, small curve, serious misalignment of the I-beam, frequent loosening of the pressure plate and the tie rod, resulting in frequent displacement of the rails, and eventually the supporting rollers and wheel-rail locomotives behind the shield machine will fall off the rails. Repair and maintenance by special personnel not only has great potential safety hazards in shield tunneling, high construction co...
