Improvement method for preventing clogging of hard loading pipes of shield machine

Abstract

Discloses is an improvement method for preventing clogging of hard loading pipes of a shield machine. A mortar tank car is connected with a first manual plate valve through a feeding hose, the first manual plate valve is connected with a second manual loading plate valve through a hard loading pipe, the second manual loading plate valve is connected with a mortar storage tank through a hard loading pipe, the hard loading pipe between the first manual plate valve and the second manual loading plate valve is connected with an intake pipe in series and connected to one end of a manual intake ballvalve, and the other end of the manual intake ball valve is connected with a one-way intake valve through the intake pipe. The improvement method has the advantages that through addition of the second manual loading plate valve, the manual intake ball valve and the one-way intake valve, the tunneling requirements of the shield machine are met, so that influences on construction of the shield machine by the clogging of the hard loading pipes are prevented effectively, and safety and reliability in construction of the shield machine are improved.

Description

technical field [0001] The invention belongs to the technical field of shield machine feeding systems, in particular to an improved method for preventing blockage of a shield machine feeding pipe. Background technique [0002] combine figure 1 , the feeding system of the existing conventional shield machine is: the mortar is finally input into the high-level slurry storage tank 5 through the mortar tanker 1, the feeding hose 2, the first manual feeding plate valve 3 and the feeding hard pipe 4, wherein the mortar The tanker 1 is equipped with a mortar pump, which is the power source for conveying mortar. The feeding hose 2 is a high-strength hose to facilitate the docking of the mortar tanker 1 with the feeding hard pipe 4. The first manual feeding plate valve 3 is connected to the feeding hose 2 and Between the feeding hard pipes 4, the slurry storage tank 5 is a temporary slurry storage container of the shield machine. [0003] Need to close the first manual feeding plat...
