Technical Field

The utility model relates to a full section tunnel tunnelling equipment field has especially related to a sediment water separator and has used device's open-type entry driving machine.

Background

A full-face tunnel boring machine is tunnel excavation equipment which is more and more widely applied. An open-type tunneling machine is one of full-face tunnel tunneling machines. The existing open-type heading machine comprises a shield body, a main drive, a cutter head, a soil bin partition plate and a muck conveying device. The shield body is cylindrical, the soil bin partition plate is annular and is arranged in the shield body, the main drive is arranged on the soil bin partition plate, the cutter head is arranged on the main drive and is positioned in front of the soil bin partition plate, and the cutter head, the shield body and the soil bin partition plate enclose a soil bin together. The muck conveying device specifically adopts a belt conveyor, the front end of the belt conveyor extends into a soil bin through a center hole of a soil bin partition plate, a muck scraper is arranged on the rear side of a cutter head, and the muck scraper and the cutter head form a structure similar to a water truck. During the tunneling process of the tunneling machine, generated muck firstly enters the soil bin through the opening on the cutter head, then is scraped by the slag scraping plate and poured onto the belt conveyor, and is conveyed to the rear by the belt conveyor so as to be conveyed out of the tunnel.

When the open-type tunneling machine tunnels on a water-rich rock layer, the muck conveying device adopts a belt conveyor and only can convey the muck, so that sewage in a tunnel cannot be discharged, after the sewage is accumulated to a certain amount, the muck can be shoveled by the scraper together with the muck, so that the muck on the muck conveying device is washed and falls below the muck conveying device, the fallen muck needs to be manually cleaned regularly, the problems of slow construction and tunneling and tunnel pollution are caused, and adverse effects are brought to construction.

Aiming at the problems, the invention patent application with publication number CN112879028A and publication date 2021, 6 months and 1 days discloses a slag-water separation structure of a soil bin of a full-face tunnel boring machine.

The soil bin slag-water separation structure of the full-face tunnel boring machine solves the problem of sewage treatment when the open boring machine tunnels in the water-rich rock layer to a certain extent. However, in the process of tunnel construction, when the water content in the stratum is large, natural drainage through the drainage pipe obviously cannot meet the drainage requirement, and if water cannot be drained in time, the problems that accumulated water submerges the host, the accumulated water leaks and the like are possibly caused. In the actual production, all need force the drainage through the water pump, however because the diameter of drain pipe is limited, drainage efficiency is lower, and the water pump needs to keep running state all the time, has improved the energy consumption cost to a certain extent. In addition, since a part of fine slag stones cannot be shoveled by the slag scraping plate, the slag stones also block the drain pipe, further reducing the drainage efficiency. After the drain pipe is blocked, the drain pipe is also inconvenient to clean.

In order to avoid the back flow of the muck into the soil bin 16 in the slag removal process, a gate 31 is arranged on one side of the water separating tank 28 close to the soil bin partition plate 19, and the problem can be avoided by closing the gate 31 in the slag removal process. The slag-removing door 30 is provided with a central hole, the soil bin communicating port of the communicating pipe 11 is inserted into the central hole and is fixedly connected with the slag-removing door 30 through the communicating pipe flange plate 20. In the use process, the gate 31 is in a normally open state, water in the soil bin 16 enters the water separating tank 28 after being primarily filtered by the filtering separator 29, entrained impurities are gathered at the lower part of one end of the water separating tank 28, which is connected with the soil bin partition plate 19, and sewage enters the water storage container after being further filtered by the filtering assembly on the communicating pipe 11. When a certain amount of impurities are accumulated in the water separating tank 28, the gate 31 can be closed, and then the slag removing door 30 is opened to remove the impurities such as the slag and the like in the water separating tank 28.
