Abstract
The utility model belongs to the technical field of slurry shield equipment in tunnel engineering, and particularly relates to a portal sealing device of a slurry shield. The portal sealing device of the slurry shield solves the problem that a traditional portal sealing device of the slurry shield is poor in sealing effect. The portal sealing device of the slurry shield comprises a portal steel ring and a cord fabric rubber plate, wherein the portal steel ring is arranged on a lining wall, the cord fabric rubber plate is arranged between the portal steel ring and a shield segment, a shield tail brush is further arranged between the portal steel ring and the shield segment, and the shield tail brush is fixedly connected with the portal steel ring. According to the portal sealing device of the slurry shield, the shield tail brush is additionally arranged and is filled with hand grease, and therefore the problems of slurry leakage of a sealed portal and soil loss are effectively solved.
Description
Technical field
The utility model belongs to slurry shield equipment technical field in construction of tunnel, specifically a kind of portal sealing device of slurry shield.
Background technology
Slurry shield starts and has great risk when sondage is entered, especially on Fu Shui stratum.Once portal sealing device can not well seal, just have a large amount of earth, underground water and run off from the gap location of cylindrical shell and portal, and shield tail is by the loss of backing grouting serous fluid after portal, causes surface collapse; And muddy water circulation pressure is difficult to set up, and slurry shield also cannot tunnel, cause spoil disposal slurry pipeline blockage.During current shield launching, generally need to install the portal temporary sealing device being formed by cord rubber tile, shape turnover panel, Circular Plate, packing ring and bolt etc.Yet for Polluted Soil region or close on the region of escape canal, construction avoids soil erosion even more important as far as possible, and conventional seals device cannot meet the demands.
Summary of the invention
The utility model, in order to solve the not good problem of portal sealing device sealing effectiveness of traditional slurry shield, provides a kind of portal sealing device of slurry shield especially.
The utility model is taked following technical scheme: a kind of portal sealing device of slurry shield, comprise the portal steel loop being arranged on inwall and be arranged on the cord rubber tile between portal steel loop and shield duct piece, between portal steel loop and shield duct piece, be also provided with shield ventral brush, shield ventral brush is fixedly connected with portal steel loop.
Described shield ventral brush is made by stainless steel wire, is filled with hand and touches grease on shield ventral brush.
Compared with prior art, the utility model has been set up shield ventral brush, and on shield ventral brush, has filled hand and touched grease, has effectively solved the problem of portal sealing spillage and soil erosion.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Fig. 2 is shield ventral brush drawing;
1-inwall in figure, 2-portal steel loop, 3-shield ventral brush, 4-shield duct piece.
The specific embodiment
As shown in Figure 1, a kind of portal sealing device of slurry shield, comprise the portal steel loop 2 being arranged on inwall 1 and be arranged on portal steel loop 2 and shield duct piece 4 between cord rubber tile, between portal steel loop 2 and shield duct piece 4, be also provided with shield ventral brush 3, shield ventral brush 3 is fixedly connected with portal steel loop 2.
Described shield ventral brush 3 is made by stainless steel wire, is filled with hand and touches grease on shield ventral brush 3.
It is example that No. 7 lines of Beijing Metro 08 of take are marked interval, station～chemical industry station, the ancient philosophers gulf, this area belongs to former chemical industry two factory's Polluted Soil regions, close on escape canal (1.5 meters of depth of water) simultaneously, in order better to seal portal, the sealing of this engineering portal adopts steel loop outside to adopt the sealing of cord rubber tile, the inner high-strength shield ventral brush together that increases, and fill with the hand fat of putting the oil.Actual slurry shield start sondage enter during effect fine, there is not portal sealing spillage problem, effectivelyly avoided soil erosion, the very fast mud hydraulic pressure balance of setting up, is worth engineering recommendation application afterwards.
