Abstract
The utility model discloses a slush shield slurry conveying system enhanced slush cabin and air cushion cabin circulation flow device, comprising an original slurry feeding loop, an air cushion cabin and a slush cabin connected to the slurry feeding loop, and an original slurry returning loop which is fixed on the air cushion cabin separating plate and is connected to the air cushion cabin. The utility model is characterized in that an assisting circulation system, a new slush loop is extra disposed in the shield host; the new slurry loop comprises a slurry absorbing pipe, a slurry pump set connected to the slurry absorbing pipe, and a slurry return pipe connected to the outlet of the slurry pump set. The utility model has advantages of enhancing the flow velocity of slurry channel in the shield host slurry slush cabin and the air cushion cabin bottom; improving the ability of carrying large-sized pebbles; preventing the problem of dreg accumulation in the slush cabin and the air cushion cabin bottom when the large-sized pebble layer is being excavated; greatly increasing the use range of slush shields; reducing the accumulation of sandy soil in the inhalation pipe of the slurry pump in large-sized grit layer; reducing the fault rate of a device.
Description
Technical field
The utility model belongs to gas cushion type mud water shield slurry transporting system circulation flow techniques field, tunnel, main a kind of new muddy water storehouse and the air cushion storehouse circulation flux enhancement system of proposing is specially the device that the slurry shield slurry transporting system strengthens muddy water storehouse and air cushion storehouse circulation flow.
Background technique
The excavation quarrel soil that is used for the modern slurry shield of tunnel piercing adopts the slurry transportation system to send outside the tunnel, the flow of mud mainly determines according to the quarrel soil amount that excavation progress needs carry, again according to flow and carry the diameter that the required flow velocity of quarrel soil is determined pipeline in the system.Because the flow velocity of mud in pipeline is enough, so carrying of quarrel soil do not have problems in pipeline.But because the muddy water storehouse (cutterhead place bin) and the air cushion storehouse cross dimension relative duct size diameter of shield structure are much bigger, mud reduces a lot at the flow velocity of these two bins, when big particle diameter cobble or broken sillar were contained in the stratum of tunnel excavation, the mud that flow velocity is very low was difficult to carry these big particle diameter pieces and flows through these two bins bottoms excessively to suction inlets of pipeline from cutterhead.The method that present slurry shield technology adopts is, prevent that by stir big particle diameter piece with the stirring rod of cutterhead rotation it is carried to bottom, air cushion storehouse in the accumulation of bottom, muddy water storehouse and with slurry flows, be provided with in bottom, air cushion storehouse simultaneously and wash away spout, clean slurry outside the tunnel after the process mud-water separation is when returning the shield structure, a part is used to wash away, and the big particle diameter piece of air cushion storehouse bottom is suspended and is carried to the suction inlet of pipeline with slurry flows.This technology is used for gravel stratum when excavation, because the gravel particle diameter is less, still be effectively, but when being used for pebble layer and excavating, effect is relatively poor.Big particle diameter piece often is deposited in this two bin bottoms, can not be carried by mud, often needs manually to enter bin and clears up.Because need band to press (air pressure caves in so that prevent the excavation face) warehouse entry operation, labor strength is big, easily suffers from hyperbarism, operating efficiency is low, and the processing time is long, has a strong impact on construction speed, the risk that exists the excavation face to cave in simultaneously.
How can provide a kind of is the science supporting facility of economic security again, strengthen shield structure main frame muddy water storehouse and air cushion storehouse bottom slurry channel flow velocity, improve the ability that mud carries big particle diameter cobble, avoiding muddy water storehouse and the long-pending problem of bottom, air cushion storehouse quarrel mound when big particle diameter pebble layer tunnels, has been a urgent problem.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of mud auxiliary circulation system that strengthens shield structure main frame muddy water storehouse and air cushion storehouse foot passage mud speed rate, can strengthen shield structure main frame muddy water storehouse and air cushion storehouse bottom slurry channel flow velocity, improve the ability that mud carries big particle diameter cobble, avoid when big particle diameter pebble layer driving muddy water storehouse and bottom, the air cushion storehouse long-pending slurry shield slurry transporting system of quarrel mound to strengthen the device of muddy water storehouse and air cushion storehouse circulation flow.
The purpose of this utility model is achieved in that
The slurry shield slurry transporting system strengthens the device of muddy water storehouse and air cushion storehouse circulation flow, comprise original loop 1 of advancing to starch, with the air cushion storehouse 3 and the muddy water storehouse 4 that have slurry loop 1 into to be connected, and be fixed on the original overfall loop 2 that is connected with air cushion storehouse 3 on 3 dividing plates of air cushion storehouse, in shield structure main frame, set up an auxiliary circulation system, promptly newly add muddy water loop 5, newly add muddy water loop 5 and comprise pulp-absorbing pipe 5.1, and the slurry pump group 5.3 that is connected with pulp-absorbing pipe 5.1, the return pipe 5.4 that is connected with slurry pump group 5.3 delivery outlets;
Described pulp-absorbing pipe 5.1 is provided with pulp-absorbing pipe gate valve 5.2, and return pipe 5.4 is provided with return pipe gate valve 5.5; Pulp-absorbing pipe 5.1 connects and is extended down to behind pulp-absorbing pipe gate valves 5.2 backs behind the main frame rear portion on the supporting stand, is connected with the suction port of slurry pump group 5.3 on being installed in stand;
Being fixed on the dividing plate of air cushion storehouse of described pulp-absorbing pipe 5.1 is positioned at the top of the mud circulation plasma discharge suction inlet in original overfall loop 2 simultaneously;
Positive beneficial effect of the present utility model is: a kind of mud auxiliary circulation system that strengthens shield structure main frame muddy water storehouse and air cushion storehouse foot passage mud speed rate, strengthen shield structure main frame muddy water storehouse and air cushion storehouse bottom slurry channel flow velocity, improve the ability that mud carries big particle diameter cobble, avoid muddy water storehouse and the long-pending problem of bottom, air cushion storehouse quarrel mound when big particle diameter pebble layer tunnels.The increase of this covering device has improved the using scope of slurry shield greatly, reduces the accumulation at bigger grit layer slurry pump suction pipe place sand, the reduction breakdown rate.
