The water blocking devices and the water pumping devices are connected at intervals to form the cofferdam. The bridge and bridge pier cofferdam integral equipment is advantaged by small equipment size, number reduction, easy installation and transportation, quick assembling, cofferdam formation, and quick recovery, and also possessing high automation degree; construction period can be greatly shortened; water areas can be divided and blocked with high efficiency; and apparatus recovery can be facilitated.
Description
Technical field
The invention belongs to technical field of bridge engineering, be specifically related to a kind of bridge cofferdam equipment integrating and construction method thereof.
Background technology
Cofferdam refers in hydraulic engineering construction, for building permanent water conservancy projects, the provisional building enclosure built.Its
Effect is to prevent what water and soil from entering building to build position, in order at cofferdam internal drainage, and excavation pit builds building.One
As be mainly used in waterwork, in addition to the part as formal building, cofferdam typically after being finished remove.Cofferdam height
Higher than the peak level being likely to occur in the construction time.
Steel sheet-pile cofferdam is the most frequently used a kind of sheet-pile cofferdam.Steel sheet pile is a kind of shaped steel with fore shaft, and its cross section has
Straight plate shape, flute profile and Z-shaped etc., have full range of sizes and interlocking form.Common are Ademilson formula of drawing, clarke Wan Nashi etc..Its
Advantage is: intensity is high, easily squeezes into hard soil layer；Can be at deep subaqueous work, water resistance is good；Various profile can be formed on demand
Cofferdam, and can repeatedly use, therefore, it of many uses.The cofferdam on open caisson top, tubing string it is usually used in bridge construction
Basis, pile foundation and the cofferdam etc. of open cut foundation.Have in these closed cofferdam of many employings single wall, cofferdam and vertically and horizontally support, necessary
Time add bearing diagonal and become an inclosure.Such as the tube caisson foudations of Nanjing of China the Changjiang river bridge, once used steel sheet pile circular cofferdam, its diameter
21.9 meters, steel sheet pile length 36 meters, after underwater concrete back cover reaches requirement of strength, draw water and build cushion cap and pier shaft, design of drawing water
The degree of depth reaches 20 meters.In waterwork, general construction area is very big, then conventional to make structure body cofferdam.It is mutual by many
The monomer connected is constituted, and each monomer is made up of many steel sheet piles again, tamps with soil in the middle of monomer.The scope that cofferdam is gone along with sb. to guard him
The biggest, it is impossible to supporting weir wall with supporting, the most each monomer can resist alone the drawing crack toppled, slide and prevent at interlocking.
Conventional has the form such as circle and next door shape.
Steel sheet-pile cofferdam is applied more in China constructs, but its construction is extensive, and cost haggles over height, between steel sheet pile composition
Also tamping with soil, such duration is longer, needs water pump ceaselessly to draw water inside cofferdam, and such operation is very trouble.
Secondly, such as Patent No. ZL201220322013.7, the applying date 2012. 07 .05, notification number
The Chinese utility model patent of CN202706045U discloses a kind of circular cofferdam, including the one group of steel being enclosed in cushion cap periphery
Sheet pile and cofferdam substrate, it is characterised in that: described steel sheet pile is arranged to tubular cofferdam wall, described steel sheet pile along cushion cap circumferential annular
Root extend to below cofferdam substrate, the top of steel sheet pile be higher than cushion cap；The medial wall being close to this group steel sheet pile is provided with and encloses
Weir, described in enclose purlin and be spaced the most successively along wall border, cofferdam and be circular layout；Described first cofferdam and the 3rd cofferdam, road are divided
Being additionally provided with in the disk at other place and fix the inner support being connected with cofferdam inwall, described inner support is the square that steel pipe encloses
Shape framework and its be arranged in parallel with cofferdam substrate.
And for example Patent No. ZL201120427362.0, the applying date 2011. 11 .02, notification number CN202359565U
Chinese utility model patent in disclose a kind of steel sheet pile cofferdam structure, be made up of steel sheet pile and weir, cofferdam body, its feature exists
In: described steel sheet pile is single, is arranged at body side near water, weir, cofferdam；Weir, described cofferdam body is filled by rock structure and forms.
Both cofferdam structures above-mentioned are commonly used in construction at present, and its construction is extensive, and the time is long, have in operation waters
Insert and bury a large amount of bamboo pole；And substantial amounts of cloth is hung up above, cloth fixing point on bamboo pole with resistance effect is many, and operation is delayed
Slowly；After operation completes, the recovery for bamboo pole and cloth excessively bothers, especially in the case of cofferdam workload is big.
Summary of the invention
The present invention is directed to disadvantage mentioned above, based on solving existing highway bridge bridge pier, the bridge pier that particularly some canal water levels are low
Cofferdam structure construction is extensive, and operation is slow, the slow-footed problem of rear material recovery of having constructed.Propose a kind of bridge cofferdam one
Body equipment and construction method thereof.This equipment and construction method thereof make installation and the dismounting in bridge pier cofferdam by the design of rational structure
Time is greatly shortened, and improves efficiency of construction.
For realizing the purpose of the present invention, the technical solution used in the present invention is:
