Abstract
The invention discloses a non-inclined dry-operation open caisson capable of preventing water burst and land subsidence and a construction method thereof. The non-inclined dry-operation open caisson capable of preventing the water burst and the land subsidence comprises a wall and a blade edge both made from reinforced concrete, wherein a water stop curtain and an uplift pile are arranged at the four sides of the open caisson; a bracket is arranged at the upper end of the outer wall of the open caisson; and the bracket is connected with the uplift pile by steel supports and lifting devices detached section by section. The construction method comprises the following steps of: firstly performing the construction of the water stop curtain and the uplift pile and then manufacturing the bottommost layer of the open caisson; after the desired strength of concrete is achieved, digging earth from the open caisson; uniformly controlling the lifting devices to sink the open caisson slowly, and then performing the construction of a former layer of open caisson upwards, continuing digging the earth and controlling the open caisson to sink to be at a designed elevation. Compared with the existing working well by using a retaining and protecting method, the non-inclined dry-operation open caisson capable of preventing the water burst and the land subsidence omits a foundation pit support with expensive construction cost, and the construction period is shorted; compared with the conventional open caisson, the non-inclined dry-operation open caisson capable of preventing the water burst and the land subsidence is safer, more environment-friendly, better in construction quality, non-inclined, and capable of performing dry operation without mud pollution; and therefore, the non-inclined dry-operation open caisson capable of preventing the water burst and the land subsidence is suitable for wide urban construction in China.
Description
Technical field
The present invention relates to the building foundation field, relate in particular to the anti-ground of a kind of anti-water burst sink not inclination dry work open caisson and job practices thereof.
Background technology
Along with China's urban construction scale constantly enlarges, the requirement of urban construction improves constantly, and the many pipe networks in city are laid the depths push pipe that goes underground by the earth's surface and laid, and Underground Rail Transit also is widely used.This will be in each access at network of underground, subway continuously excacation well along the line or underground station and station, common all kinds of active well and foundation ditch adopt the churning supporting that adds high pressure of steel concrete diaphragm wall, SMW engineering method, drilled pile more, not only involve great expense, and the duration is very long; The construction of employing drop shaft sinking, though expense is lower, open caisson is different because of underground soil layer property, as easy as rolling off a log inclination is difficult to control its verticality, when underground soil layer contains layer of sand, just can produce quicksand, the outer ground of open caisson is sunk, in the urban construction that network of underground is arranged, just can't use.
Summary of the invention
Technical problem to be solved by this invention is: the anti-ground of a kind of anti-water burst sink not inclination dry work open caisson and job practices thereof are provided, in the city, construct, open caisson does not tilt, can do operation in well fetches earth, without water burst, and prevent that the outer ground of well from sinking, and reduces the urban construction investment, this open caisson construction civilization, mud-less pollution, the duration is short.
The technical solution adopted in the present invention is: the anti-ground of a kind of anti-water burst sink not inclination dry work open caisson and job practices thereof, the same with prior art, the borehole wall that all includes steel concrete, borehole wall lower end is provided with the sword pin, sword pin front end is provided with cuts the mud steel plate, it is characterized in that, the open caisson periphery is provided with water-stop curtain and the uplift pile of controlling well sinking, be provided with bracket in open caisson outer wall upper end, between bracket and uplift pile, support and link to each other a strong point two lifting gears arranged side by side with lifting gear by dismantling section by section steel.
The further technical scheme of the present invention is: described water-stop curtain is cement mixing pile or high-pressure rotary jet grouting pile, and described lifting gear is spiral lift or jack, its specification 50-200 ton, and the described steel of dismantling section by section supports the stroke that every joint highly is equal to lifting gear.
The open caisson load is passed to uplift pile by lifting gear, for saving investment, reduce uplift pile stake number, dismantle section by section steel and support the two lifting gears of employing one post, there is the hole of 50-200mm to be used for passing the rod iron of accepting another lifting gear bearing load at a upper joint support column, namely working as a lifting gear stroke is finished, pierced rod iron at a upper joint steel supported hole, the load of another lifting gear supporting caisson is installed, dismounting is supported without a joint steel above the stroke lifting device, jacking stroke again again sheds the interim lifting gear that supports of being used for, and open caisson again sinks.
The anti-ground of above-mentioned a kind of anti-water burst sink not inclination dry work open caisson construction and job practices thereof comprise following construction sequence successively:
(1), construction open caisson peripheral water stopping curtain;
(2), construction is positioned at the uplift pile of open caisson periphery;
(3), make bottom open caisson, comprise reinforcing bar binding, weldering bracket and sword pin steel plate, formwork, fluid concrete and maintenance;
(4), put the lifting gear of two positioning system of changed liftings at the stake roof panel, connect on the lifting gear and dismantle section by section steel and be supported to bracket;
(5), form removal after the open caisson concrete strength reaches, and cut the earth in the open caisson and outward transport;
(6), along with the continuous taking-up of soil in the well, the unified regulation and control of lifting gear adopt stepper motor or manually-operated control open caisson vertically, not tilt to sink at a slow speed;
(8), continue upwards to make the last layer caisson wall by prior art, comprise reinforcing bar binding, weldering bracket, formwork, fluid concrete and maintenance;
(9), continue to cut the earth downwards with the regulation and control well sinking to design elevation.
The anti-ground of a kind of anti-water burst sink not inclination dry work open caisson and job practices thereof compared with prior art, have obvious superiority: compare with the method for support construction of working shaft, save the pattern foundation pit supporting structure and the support engineering engineering time that involve great expense; Compare with the construction of conventional drop shaft sinking, this open caisson construction is safer, environmental protection, do not tilt, do operation, mud-less pollution, and construction quality is better, and it is applicable to the vast urban construction of China.
The invention will be further described below in conjunction with accompanying drawing and the specific embodiment.
