A kind of shield excavation machine, comprise shield structure support, be located at the cutterhead of this shield structure support front end, be located at the section of jurisdiction in shield structure support rear portion, be located at the rear end of this shield structure support and the front end shield ventral brush successively arranged along the tunneling direction of shield excavation machine respectively and rear end shield ventral brush, this front end shield ventral brush and rear end shield ventral brush abut against with section of jurisdiction respectively, and with space therebetween in be filled with filler, this shield excavation machine also comprises to be located on this shield structure support and to be positioned at the glue brush in the front of front end shield ventral brush, this glue brush and section of jurisdiction lean, a space is formed between described glue brush and front end shield ventral brush and section of jurisdiction, fill out in this space and be provided with lubricating fluid.
Preferred version is, described lubricating fluid is oil or lubrication oil.
Preferred version is, the top in described space is connected with an ascending pipe.
Preferred version is, described ascending pipe passes shield structure support by the top in space and leads to its external world.
Preferred version is, this shield excavation machine also comprises the jack for providing thrust to the entirety of propelling development machine be located in shield structure support.
Preferred version is, this shield excavation machine also comprises to be located in shield structure support, and for discharging the conveying worm of sandy soil.
Preferred version is, described front end shield ventral brush and rear end shield ventral brush are wire brush.
The beneficial effects of the utility model are:
Shield excavation machine in the utility model, owing to being interval with glue brush in the front of front end shield ventral brush, and in being provided with lubricating fluid therebetween, thus to lubricate front end shield ventral brush, prevent front end shield ventral brush with abutting for a long time between section of jurisdiction and wear and tear, extending its application life.And the spatial joins between this glue brush and front end shield ventral brush has the ascending pipe that can inject lubricating fluid, even if also can ensure when constructing at a distance to lubricate front end shield ventral brush.
