As a large amount of concrete materials are used in tunnel construction, in areas with abundant underground water, water seeps into the concrete materials to carry calcium ions out of the concrete materials, reacts with CO2 in the air or CO 32-and HCO 3-in seepage underground water to generate insoluble matters such as calcium carbonate and the like, and enters a tunnel drainage system along with water flow. Because the longitudinal slope in the tunnel is small, the on-way resistance of long-distance drainage is large, the flow velocity of water in the drainage pipe is small, and insoluble matters such as calcium carbonate and the like have good adhesion with the pipe wall of a tunnel drainage system, the insoluble matters can be gradually accumulated in the drainage system, and finally local blockage is generated, so that disasters such as paralysis of the drainage system, incapability of draining underground water, reduction and cracking of lining strength, shutdown of the tunnel and the like are caused. In addition, as the tunnel lining belongs to hidden engineering, the repair is inconvenient after the tunnel lining is damaged, and the accumulation speed of insoluble matters is increased along with the increase of the deposition amount. Therefore, how to rapidly and effectively remove the insoluble matters in time and dredge the drain pipe so that the tunnel is in a normal operation state is a problem which is urgently needed to be solved at present.
At present, three common methods for dredging the crystals of the tunnel drain pipe are provided: (1) a physical method, which adopts a physical crushing mode to clean crystals or adopts an electromagnetic technology to prevent the drain pipe from crystallizing; (2) a chemical method, which adopts an acid dissolution mode to clean crystals or adopts a mode of adding a scale inhibitor, changing flow rate, temperature and the like to prevent the generation of the crystals; (3) biological method, which accelerates the dissolution of the crystal or prevents the generation of the crystal by adding biological flora and the like. Wherein, because the latter two methods have lower efficiency, the cleaning is usually carried out by using a physical crushing mode in practice at present.
Because tunnel drain pipe section size is less, longitudinal length is longer, and the mode that present most drain pipe crystalline substance breaker adopted small motor to equip with full section cutter is cleared up the breakage forward, and the cutter generally carries out the rotary cutting with the face contact form that is on a parallel with the cross section, but this mode has the following problem:
(1) under the condition of certain motor power, the contact area between a surface contact type cutter head and a crystal is large, so that the cutting efficiency is too low, and particularly, the crystal with high hardness and large volume can rotate;
(2) the existing crystal crushing device is generally small and not easy to keep balance, and when a cutter head rotates parallel to a section, an equivalent reverse torque is generated on the device, so that the self balance of a vehicle body and the stability of an internal structure are damaged;
(3) the device lacks a relatively complete shell protection structure, and the debris generated in the cutting process of the device can damage the internal structure.
