Novel small-diameter slurry shield tube-changing device

Abstract

The invention provides a novel small-diameter slurry shield tube-changing device, and the problem that a tube-changing device is not suitable for a small-diameter slurry shield in the prior art is solved. The novel small-diameter slurry shield tube-changing device comprises a slurry-feeding extension tube and a slurry-discharging extension tube. The slurry-feeding extension tube is connected with a slurry-feeding tube, the slurry-discharging extension tube is connected with a slurry-discharging tube, and the slurry-feeding extension tube and the slurry-discharging extension tube are arranged on a first trolley; the slurry-discharging tube and the slurry-feeding tube are arranged on a second trolley, a hydraulic winch is arranged on the first trolley, and a hauling pulley is arranged on the second trolley; and a rope of the hydraulic winch is connected with the hauling pulley, a slurry-discharging ball valve and an expansion joint are arranged on the slurry-discharging tube, and a slurry-feeding ball valve and an expansion joint are arranged on the slurry-feeding tube. According to the novel small-diameter slurry shield tube-changing device, a muddy-water pipe is driven to move while shield excavation is achieved by adopting a trolley and an extension tube which move relatively, and the structural arrangement is simple; a constructor conducts the tunneling-tube adding-tunneling step repeatedly, synchronous lengthening of the muddy-water pipe can be achieved, and the operation is convenient; and a complete set of device is low in price, the cost is saved, the occupied space is small, and the novel small-diameter slurry shield tube-changing device is suitable for small-diameter shield tunneling machines.

Description

technical field [0001] The invention relates to the technical field of excavation and construction of a tunnel shield machine, in particular to a novel small-diameter mud-water shield pipe changing device. Background technique [0002] With the development of the economy and the acceleration of urbanization, the construction of small-diameter tunnels for common pipes in cities, including water pipes, sewage pipes, gas pipes, heat pipes, power cables, and communication cables, has grown rapidly. These tunnels all require small-diameter shield tunnels for excavation, and shield tunnels are gradually popularized due to their many advantages such as safety and speed. Small-diameter slurry shields have good market prospects. [0003] Most of the muddy water pipe changing devices commonly used at present reserve a long enough hose on the top of the trolley to meet the needs of the forward movement of the slurry inlet and discharge pipelines. The positions of the two trolleys rema...
