Abstract
The utility model relates to a composite shield construction machine which comprises a shield construction shell, a broadsword plate, a section ring, a supporting ring, a shield end, a shield structure tunneling system, a duct piece assembling machine and a screw transporter. The broadsword plate body is provided with a detachable joist, the plate panel is crossing provided with a disc-shaped rolling knife and a leading knife, the two sides of the side plate are provided with a foldable scraper, the external edge of the broadsword plate is provided with a side knife, the external edge of the front edge of the broadsword plate body is provided with a copying knife, and the soil discharging position of the screw transporter is provided with two strobes. When one of the strobes of the screw transporter is faulted, the other strobe can efficiently shut off the outlet of the screw transporter in order to prevent the overflowing of the mud. The utility model can be used for complex stratum shield construction such as strength weathered rock, N=22-45 clay, sandy soil and cobble.
Description
Technical field
The utility model relates to a kind of engineering heading equipment, particularly a kind of driving shield machine that is used for the soil layer construction.
Technical background
Development along with urban construction, the continuous increase of subway, underground comb engineering, underground heading equipment is also had higher requirement, especially particularly important to the design that contains compound foundation soils such as clay, sandy soil, sand-pebble, rock, heading equipment simultaneously, the underground driving that existing shield machine only is suitable for single soil layer can not satisfy the geology construction that contains different soil simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of energy to carry out the equipment of shield-tunneling construction in not decomposed rock, cobble, pan soil stratum effectively.
To achieve these goals, the technical scheme that the utility model adopted is: a kind of compound shield comprises shield structure housing, big cutterhead, otch ring, Supporting ring, shield tail, shield driving system, duct piece assembling machine, conveying worm.Be equipped with dismountable joist on the cutterhead disk body, intersection is provided with hobboing cutter and the cutter of going ahead of the rest on the card panel, is respectively equipped with dismantled and assembled scraper in the former both sides, is provided with the limit cutter on the cutterhead outer rim, is provided with imitation-shaped knife on the radially position of cutterhead disk body forward position outer rim.
Conveying worm casting place is provided with two road gates; Hobboing cutter is formed 17 inches back loading type hobboing cutter by 22; Scraper is formed dismantled and assembled scraper by 24; The limit cutter is made up of the wear-resistant cutter of cutterhead outer rim tungsten carbide button.
The utility model is owing to adopted technique scheme, therefore the beneficial effect that has is: two road gates are equipped with in conveying worm casting place, when one gate of conveying worm breaks down, another road gate can be closed the screw machine outlet effectively, prevent that muddy water is excessive, the utility model shield machine can be suitable for strong and weak decomposed rock, N=22-45 clay, sand, cobble bad ground shield-tunneling construction.
Description of drawings
Fig. 1 is a big cutterhead structural representation of the present utility model;
Fig. 2 is a conveying worm structural representation of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The utility model compound shield is made of shield structure housing, big cutterhead, otch ring, Supporting ring, shield tail, shield driving system, duct piece assembling machine, conveying worm etc.Wherein big cutterhead, as shown in Figure 1, form by cutterhead disk body 1, hobboing cutter 2, scraper 3, the parts such as cutter 4, limit cutter 5, imitation-shaped knife 6, pressure injection pipeline, mixing arm of going ahead of the rest, dismountable joist is housed on cutterhead disk body 1, on the card panel, intersect and be equipped with 22 the 17 inches back loading type hobboing cutters 2 and the cutter 4 of going ahead of the rest, install 24 unevenly removable scraper 3 two former both sides, on the cutterhead outer rim, inlay the limit cutter of forming by the wear-resistant cutter of carbide alloy 5, on the radially position of cutterhead disk body forward position outer rim, imitation-shaped knife 6 is housed.Imitation-shaped knife can slide separately on the guide peg in sheath, stroke 100mm, and the shape of backbreaking is come profiling control by hydraulic jack.Swivel coupling is equipped with at the center of cutterhead, one road water pipe wherein, and one road mud pipe, the center is used for water filling or annotates mud, and water pipe, the mud pipe is to the water filling of cutterhead panel or annotate mud, and with lubricated cutterhead card, mud injection pipe diameter phi 50mm, maximum pressure are 4Mpa.
Shown in Figure 2, conveying worm is that foreign material such as the soil that will excavate in the shield structure sealed compartment or rock slag are discharged.Conveying worm inlet is positioned at shield structure sealed compartment, and it is 1.3 pitch that its screw machine blade stretches out the shifting board overhang.To guarantee having enough soil bodys to enter in the screw machine cylindrical shell.Conveying worm also has a very important function in the earth pressure balance tunneling process, control casting amount is kept the correct soil pressure of work plane.Spiral machine tube inner wall head advances the Tu Chu interior build-up wear-resistant carbide alloy of 1000mm scope longitudinally.Sleeve is an ingredient of otch ring structure, in shield structure housing, sleeve is equipped with flange, can link to each other with the screw machine interlude, interlude is the drive sleeve tube, two end flanges and twice are housed check spiral or unearthed aperture of door and detect the diaphragm pressure gage that the soil pressure situation changes, the sensor of accepting soil pressure is housed at its Tu Kou edge that advances.And two of screw machine two pressure injection water pipes are housed in case water filling in time and slip casting in order to lubricated and sealing.Two road gates 7 are equipped with in casting place, when conveying worm breaks down, can close the screw machine outlet effectively, prevent that muddy water is excessive.
