Background
In recent years, with the large development of urban rail transit in China, the shield method is widely applied to rail construction due to the advantages of safety, high efficiency, wide adaptability and the like. The earth pressure balance shield is becoming the first choice for shield construction under various composite stratum conditions due to wide stratum adaptability and strong rock breaking capacity. However, in the construction of water-rich stratum, the water content in the stratum is large, so that the problems of breakage, loosening and the like are very easy to occur when the shield machine is in the crossing process due to the weathering of the stratum. When the screw conveyor is not well sealed or the underground water pressure is high, the gushing phenomenon is very easy to occur. The generated gushing ensures that a large amount of sediment and water flow are accumulated at the tail of the shield, the segment conveyor is completely submerged, normal tunneling is impossible, manual cleaning is needed at regular time, and the shield construction efficiency is restricted. In addition, in the process of transporting the dregs, the dregs and mud water slide down or splash to the bottom of the belt conveyor, and a large amount of sediment and water flow are accumulated at the tail of the shield.
In the prior art, a screw machine is modified to prevent gushing, for example, a U-shaped airtight screw machine gushing prevention system capable of separating slag from water and a gushing prevention method are disclosed in the patent No. 201910934542.9, and the U-shaped airtight box capable of separating slag from water is additionally arranged below the screw machine, so that the screw conveyor can be matched with a mud water pump to work so as to separate the mud from the water of slag. But when the gushing volume is big, on unavoidable having unseparated muddy water was discharged to the belt feeder through the second screw machine, a part was slipped from the belt feeder bottom, and a part was splashed to the belt feeder below from the belt feeder both sides, can lead to the shield tail to pile up a large amount of silt and rivers in a period, needs the manual clearance of timing, has restricted shield construction efficiency.
Therefore, if the problem that the slag soil and mud water slide down or splash below the belt conveyor in the process of falling and transporting the slag soil onto the belt conveyor is not solved, the shield construction efficiency is severely restricted.
The improvement measure related to the belt conveyor at present is that in the manufacturing method of a device for collecting and removing dregs in the spiral gushing process in shield construction, a dreg receiving groove is provided, the front part and the tail part of the dreg receiving groove are respectively provided with an ear plate, the ear plates at the front part of the dreg receiving groove are connected with a driven wheel frame of the belt conveyor through pin shafts, wherein the structure that the dreg receiving groove can freely rotate by taking the pin shafts as the center limits that the edge of the dreg receiving groove cannot exceed the edge of the lower part of the belt conveyor, and therefore, the collection effect on the bottom end of the belt conveyor is extremely poor. In a spiral machine blowout prevention structure for shield construction, patent number 202021680646.6 proposes to design the tray below the belt feeder, the tray is laid in parallel with the belt feeder slant, along with the increase of dregs collection amount, can lead to the range between accomodating the groove bottom and accomodating the groove export and produce and pile up, lead to subsequent dregs muddy water to flow out along piled dregs and accomodate the groove, simultaneously accomodate the dregs muddy water inflow that the groove export flowed out and set up in the other receiving hopper of belt feeder, receiving hopper has occupied belt feeder lower part section of jurisdiction loop wheel machine hoist and mount section of jurisdiction space, influence subsequent process efficiency of construction, shield construction efficiency has been reduced.
Therefore, the special rapid cleaning equipment and cleaning method for the gushing and slag falling of the shield belt conveyor are required to be designed, and on the basis of not occupying the construction space of the pipe piece lifting machine for lifting the pipe pieces, the slag and muddy water which slides from the bottom end of the belt conveyor and splashes to the lower part of the belt conveyor from the two sides of the belt conveyor are rapidly cleaned, and meanwhile, the normal propulsion of the shield machine is not influenced.
