Description

Technical Field

[0001] The utility model relates to the technical field of discharging obstacle materials encountered in mud-water balance rectangular pipe jacking construction, in particular to an emergency system of a novel rectangular machine rapid slag discharging device. Background Art

[0002] At present, the working principle of mud-water balance rectangular pipe jacking construction is to use the pipe jacking machine cutter to cut the coating and crush the stone. The soil cut by the cutter is mixed into the slurry to form a denser and more concentrated mud in the mud tank. This mud is pumped to the ground vibrating screen through the slurry discharge pipe. The vibrating screen separates the dense and highly concentrated mud from the water during vibration, realizing recycling and green environmental protection construction. During the pipe jacking process, a mud balance device is used to maintain the water and soil balance, so that the jacking pipe is always between the active and passive earth pressures, which can eliminate the settlement and uplift of the ground.

[0003] Since the current rectangular pipe jacking machines do not have the crushing function, if the mud-water balance rectangular pipe jacking machine encounters an obstacle material blocking the slurry discharge port during the jacking process, the mud transportation cannot operate normally, which seriously affects the jacking construction of the pipe jacking machine, and even the jacking construction cannot be carried out. It is necessary to stop the machine for troubleshooting. If necessary, it is also necessary to judge according to the geological and groundwater conditions whether it is possible to open the warehouse to clear the obstacle material (for example, in poor strata such as quicksand layers, high groundwater level strata, silt layers, etc., there is no window for troubleshooting). In addition, if the size of the rectangular pipe jacking machine is small, the internal space of the pipe jacking machine is limited. The existing mud transportation system has a long suction range, high energy consumption, low transportation efficiency, and poor flexibility. It is necessary to further improve the mud transportation of the rectangular pipe jacking machine so that the obstacle material blocking the slurry discharge port can be cleared efficiently, safely and quickly under various geological conditions inside the pipe jacking machine.

[0007] Furthermore: it also includes a high-pressure pipe, which is located above the mud-water transition chamber, and a nozzle is provided on the high-pressure pipe, and the nozzle is opposite to the slurry discharge port.

[0008] Furthermore: the first valve body is a hydraulic gate valve.

[0009] Furthermore: the second valve body is a ball valve.

[0010] Furthermore: the first valve body is connected to the mud-water transition chamber through a fixed flange plate, and the first valve body is connected to the elbow through a connecting flange plate.

[0011] Furthermore: the second valve body is connected to the elbow through a mounting flange plate, and the second valve body is connected to the hose through a docking flange plate.
