Abstract
The utility model belongs to the technical field of tunnel excavation. A novel karst area V level country rock section tunnel excavation equipment, is including the leading excavation section, the advance support who sets up at leading excavation section rear portion that are step form and set up at the anterior mud jacking securing device of leading excavation section, mud jacking securing device including set up a series of slopes of leading excavation section top align to grid make progress the mud jacking pipe, be grout hole, pulping machine and the both ends of circumference evenly distributed on the mud jacking pipe respectively through the mudjack of defeated thick liquid pipeline intercommunication pulping machine with the mud jacking pipe, be located leading excavation section foremost still be provided with the negative pressure pipe of managing to find time, the negative pressure manage to find time to be the circumference equipartition on the pipe and has seted up the negative pressure hole, the negative pressure manage to find time pipe intercommunication and have the negative pressure vacuum pump. The utility model discloses overall structure reasonable in design adopts the grout of mudjack malleation, negative pressure vacuum pump to carry out the negative pressure evacuation to the tunnel country rock that form that the density is strong, whole stable in structure, mud jacking thickness can be guaranteed effectively, it can effectual improvement efficiency of construction and construction quality.
Description
Technical field
The utility model belongs to tunnel excavation technical field, is specifically related to a kind of novel karst area V level country rock section tunnel digging equipment.
Background technology
For in tunnel excavation process, run into its whole geologic structure of karst area comparatively complicated, easily occur seeping water, the problem of landslide, the many employings of existing construction means are backbreak and are carried out deep-layer reinforcing, but along with the change of long Karst Geological Landscape, effect is not ideal enough, and reinforcing finite thickness, also have adopt grouting but grouting effect not ideal enough, the object of deep-layer reinforcing cannot be accomplished, be only local grouting, be easy to occur grouting dead angle.
Utility model content
The purpose of this utility model is for above-mentioned Problems existing and deficiency, a kind of reasonable in design is provided, the grouting of overall employing mudjack malleation, negative-pressure vacuum pump are carried out negative pressure and are vacuumized, thus forms the strong novel karst area V level country rock section tunnel digging equipment of density.
For achieving the above object, the technical scheme taked is:
A kind of novel karst area V level country rock section tunnel digging equipment, comprise in step-like advanced excavation section, be arranged on the advance support at advanced excavation section rear portion and be arranged on the mud jacking securing device of advanced excavation section front portion, described mud jacking securing device comprises and is arranged on evenly distributed a series of in advanced excavation section top and tilts upward slurry pressuring tube, be circularly and evenly distributed the grout hole on slurry pressuring tube, pulper and two ends are communicated with the mudjack of pulper and slurry pressuring tube respectively by stock line, the described advanced excavation section negative pressure that is also provided with foremost that is positioned at is found time conduit, described negative pressure finds time circumferentially uniformly on conduit to offer negative pressure hole, described negative pressure conduit of finding time is communicated with negative-pressure vacuum pump.
Described stock line is provided with pressure sensor.
Adopt technique scheme, acquired beneficial effect is:
The utility model overall construction design is reasonable, the grouting of employing mudjack malleation, negative-pressure vacuum pump are carried out negative pressure and are vacuumized, thus formed density strong, total stablizes, mud jacking thickness can obtain the tunnel surrounding that effectively ensures, it can effectively improve efficiency of construction and construction quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that slurry pressuring tube or negative pressure are found time the structural representation of conduit.
Sequence number in figure: 1 for advanced excavation section, 2 for advance support, 3 for slurry pressuring tube, 4 for grout hole, 5 for pulper, 6 for stock line, 7 for mudjack, 8 for negative pressure find time conduit, 9 for negative pressure hole, 10 for negative-pressure vacuum pump, 11 be pressure sensor.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
See Fig. 1, Fig. 2, a kind of novel karst area V level country rock section tunnel digging equipment, comprise in step-like advanced excavation section 1, be arranged on the advance support 2 at advanced excavation section 1 rear portion and be arranged on the mud jacking securing device of advanced excavation section front portion, described mud jacking securing device comprises and is arranged on evenly distributed a series of in advanced excavation section top and tilts upward slurry pressuring tube 3, be circularly and evenly distributed the grout hole 4 on slurry pressuring tube 3, pulper 5 and two ends are communicated with the mudjack 7 of pulper 5 and slurry pressuring tube 3 respectively by stock line 6, described advanced excavation section 1 negative pressure that is also provided with foremost that is positioned at is found time conduit 8, described negative pressure finds time circumferentially uniformly on conduit 8 to offer negative pressure hole 9, described negative pressure conduit 8 of finding time is communicated with negative-pressure vacuum pump 10, described stock line is provided with pressure sensor 11.
The utility model overall construction design is reasonable, the grouting of employing mudjack malleation, negative-pressure vacuum pump are carried out negative pressure and are vacuumized, thus formed density strong, total stablizes, mud jacking thickness can obtain the tunnel surrounding that effectively ensures, it can effectively improve efficiency of construction and construction quality.
