Abstract
The utility model provides a water-burst-proof ground-subsidence-proof non-inclination dry work sinking well, comprising a reinforced concrete well wall and an edge foot, the sinking well is characterized in that the circumference of the sinking well is provided with a waterstop curtain and an anti-pulling pile, a bracket is disposed at the upper end of the outer wall of the sinking well, a segment-by-segment dismounting steel support is connected with a lifting device between the bracket and the anti-pulling pile. The construction steps of the sinking well are characterized in that: the waterstop curtain and the anti-pulling pile are firstly constructed, then the bottom layer of the sinking well is manufactured, after the strength of concrete is reached, earth is dug out from the sinking well, the lifting device is regulated in unification, and is sunk at a low speed, and an upper layer of the sinking well is constructed upward, earth digging is continued and the sinking well is regulated to sink to a design elevation. Compared with a current support method work well, the sinking well saves expensive ground pit supports and shortens construction period; compared with a conventional sinking well, the sinking well is advantaged by higher safety, environmental friendliness, no inclination, dry work, no slurry pollution, better construction quality, and suitability for construction in many cities in our country.
Description
Technical field
The utility model relates to a kind of building foundation field, relates in particular to the anti-ground of a kind of anti-water burst and sinks to not tilting to do the operation open caisson.
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 face of land and laid, and the underground rail traffic also is widely used.This will be in each access at network of underground, subway excacation well continuously 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 worker's 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 caved in, in the urban construction that network of underground is arranged, just can't use.
Summary of the invention
The utility model technical problem to be solved is: provide the anti-ground of a kind of anti-water burst to sink to not tilting to do the operation open caisson, in the city, construct, open caisson does not tilt; Can in well, do operation fetches earth; No 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 scheme that the utility model adopted is: the anti-ground of a kind of anti-water burst sinks to not tilting to do the operation open caisson, and is the same with prior art, all includes the borehole wall of steel concrete; Borehole wall lower end is provided with the sword pin, and 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, link to each other a strong point two lifting gears arranged side by side with lifting gear by supporting by joint dismounting steel.
The further technical scheme of the utility model is: said water-stop curtain is high-pressure slip-casting or cement mixing pile or high-pressure rotary jet grouting pile; Said lifting gear is spiral lift or jack; Its specification 50-200 ton, the said joint dismounting steel that pursues supports the stroke that every joint highly is equal to lifting gear.
The open caisson load is passed to uplift pile through lifting gear, for practicing thrift investment, reduces uplift pile stake number; Dismantle steel by joint and support the two lifting gears of employing one post, on a last joint support column, have the hole of 50-200mm to be used to pass the rod iron of accepting another lifting gear bearing load, promptly work as a lifting gear stroke and use up; Pierced rod iron at a last joint steel supported hole; The load of another lifting gear supporting caisson is installed, is dismantled above the no stroke lifting device joint steel and support, again jacking stroke again; Shed and be used to the lifting gear that supports temporarily, open caisson once more sinks.
The anti-ground of above-mentioned a kind of anti-water burst sinks to not tilting to do the operation open caisson construction, comprises 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), on the stake roof panel, put the lifting gear that two chaptrels change up-down, connect on the lifting gear by joint dismounting steel and be supported to bracket;
(5), reach the back form removal, and cut the earth in the open caisson and outward transport at the open caisson concrete strength;
(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, comprise reinforcing bar binding, weldering bracket, formwork, fluid concrete and maintenance by prior art;
(9), continue to cut the earth downwards and regulate and control well sinking to design elevation.
The anti-ground of a kind of anti-water burst sinks to not tilting to do the operation open caisson, compared with prior art, has obvious superiority: compare with the construction of method of support active well, 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.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings
Fig. 1 is the utility model embodiment sketch map.
Drawing explanation: 1. the assorted soil layer in the face of land, 2. the sword pin cut the mud steel plate, 3. sword pin, 4. the open caisson outer wall 5. supports by joint dismounting steel; 6. bracket, open caisson 7. yet to be built, 8. lifting gear, 9. uplift pile; 10. mud, 11. water-stop curtains, 12. layers of sand, 13. silt clay layers.
The specific embodiment
Embodiment as shown in Figure 1; The enforcement that the anti-ground of a kind of anti-water burst sinks to not tilting to do the operation open caisson is: construction open caisson peripheral water stopping curtain (11) and uplift pile (9) earlier, make the concrete of cutting mud steel plate (2), formwork, cast sword pin (3) and open caisson outer wall (4) of reinforcing bar binding, weldering bracket (6) and the sword pin of one deck of the end of open caisson again; The demoulding after the concrete strength of sword pin (3) and open caisson outer wall (4) reaches; Two lifting gears (8) on uplift pile (9) stake top are gone up to install by joint dismounting steel and are supported (5) to bracket (6); In open caisson outer wall (4), cut the earth and outward transport; Along with the continuous taking-up of soil in the well, lifting gear (8) adopts stepper motor or manually-operated, unified control open caisson vertically, do not tilt, sink at a slow speed.Last layer open caisson yet to be built (7) continues upwards construction by prior art, continues downward shoveling sedimentation open caisson, makes well sinking to design elevation.
