Abstract
A thin-walled steel box comprises a box wall. The box wall is formed by connecting and welding a plurality of side forms end to end. A ring beam is welded on the inner side of the box wall. Inner supports are welded inside the ring beam. Each side form is composed of two face plates and a steel channel which is located between the two face plates and is connected with the face plates by electric welding. The steel-channeled end of each side form serves a form head, and the non-steel-channeled end of each side form serves a form tail. 15mm of the steel channel on each form head is embedded into the corresponding form tail. The two face plates at each form tail are connected with the steel channel on the corresponding form head by electric welding. The ring beam is formed by welding and connecting a plurality of ring beam modules end to end. The ring beam and the side forms are subjected to intermittent welding by 10cm per 30cm. The thin-walled steel box has the great advantages that construction cost is reduced, construction difficulty is reduced, construction efficiency is improved and the like.
Description
Technical field
The utility model relates to a kind of Steel Thin-Wall casing, belongs to the stop water field of the medium-and-large-sized deep water foundation of inland river bridge engineering.
Background technology
At present, for the bridge deep water foundation, conventional construction method is to adopt double-walled steel bushing case, and general thickness is at 800mm～1500mm.Like Qian Jiangsi bridge master pier cushion cap 45.2m x13.6m, double-walled steel cofferdam wall thickness is 1.2m, and overall height is 13.0m; Qian Jiangwu bridge master pier cushion cap buried depth 12m, casing thickness is 80cm.Qian Jiangliu bridge cushion cap planar dimension is 25.6m * 13.4m, the thick 5.5m of cushion cap, and cofferdam casing overall height is 22.0m, wall thickness reaches 1.5m.On mounting method, generally be employed in factory process, after transportation by driving puts in place, sink through ballast.These class methods are generally used in great rivers, need heavy mechanical equipment (towboat, crane barge) auxiliary construction, and construction investment is generally bigger.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned existence, and a kind of effective simplification is provided construction technology has reduced difficulty of construction, has accelerated speed of application, has improved the Steel Thin-Wall casing of economic benefit.
The purpose of the utility model is accomplished through following technical scheme, and it comprises a cover tank wall, and described cover tank wall is weldingly connected from beginning to end by a plurality of side forms and forms, and this cover tank wall inboard is welded with collar tie beam, is welded with interior support in this collar tie beam.
As preferably, described side form is made up of two panels and a channel-section steel, and this channel-section steel is sandwiched between two panels, and adopts electric welding to connect.
As preferably, described side form is that mould is first with an end of trough of belt steel, and an end of no channel-section steel is the mould tail, and the channel-section steel on the mould head is embedded in the mould tail 15mm of another side form, and two panels of mould tail are connected with the channel-section steel employing electric welding on the mould head.
As preferably, described collar tie beam is weldingly connected from beginning to end by a plurality of collar tie beam modules and forms, and adopts intermittent weld between collar tie beam and side form, and is every at a distance from 30CM, welding 10CM.
As preferably, supporting what adopt in described is Two bors d's oeuveres shaped steel, and in both sides additional iron plate.
The beneficial effect of the utility model is: 1, on the construction costs, and the one, the casing field machining is made, and compares factory process, greatly reduces cost of manufacture, also can save corresponding freight; The 2nd, casing monolithic weight is lighter, during assembly unit gantry crane lifting can be set inside, has significantly reduced value of machinery; The 3rd, casing can cut off, and can recycle basically as the steel plate and the shaped steel of main material; 2, on the difficulty of construction, casing is made and is adopted all welded construction, and manufacture difficulty is lower, and the electric welding quality reaches half requirement of three grades of weld seams, guarantees water-tight; The cofferdam sinks to adopting not dewatering excavation, utilizes the casing deadweight to add the jack back-pressure, operates comparatively simple; 3, speed of application is mainly reflected in assembly unit and sinks two aspects.Casing monolithic weight is lighter, is convenient to lifting, and only need increase input some small-sized crane gear and operating personnel just can significantly improve assembly unit efficient.Cover caisson sinking process, elder generation's utilization are conducted oneself with dignity and are inner except that native drag reduction sinking, and in the time of can not drowning oneself, it is heavy that the startup back-pressure helps.

Label in the accompanying drawing is respectively: 1, cover tank wall, 2, collar tie beam, 3, interior support, 11, side form, 21, the collar tie beam module, 111, panel, 112, channel-section steel.
The specific embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: like Fig. 1, shown in 2, the utility model comprises a cover tank wall 1, and described cover tank wall 1 is weldingly connected by a plurality of side form 11 head and the tail and forms, i.e. the cofferdam; This cover tank wall 1 inboard is welded with collar tie beam 2, supports 3 in these collar tie beam 2 inboards are welded with, and is integral rigidity and the opposing water and soil pressure that guarantees the cofferdam, in the cofferdam, establish three layers of collar tie beam 2 and in support 3, every layer of collar tie beam 2 and the weldering of cover tank wall 1 inside panel are even.What support 3 employings in described is Two bors d's oeuveres shaped steel, and adds iron plate in both sides.
Shown in accompanying drawing 3, described side form 11 is made up of two panels 111 and a channel-section steel 112, and this channel-section steel 112 is sandwiched in 111 of two panels, and adopts electric welding to connect.Described side form 11 is that mould is first with an end of trough of belt steel, and an end of no channel-section steel is the mould tail, and the channel-section steel 112 on the mould head is embedded in the mould tail 15mm of another side form 11, and two panels 111 of mould tail are connected with the channel-section steel 112 employing electric welding on the mould head.
Described collar tie beam 2 is weldingly connected by a plurality of collar tie beam module 21 head and the tail and forms, and 11 of collar tie beam 2 and side forms adopt intermittent weld, and be every at a distance from 30CM, welding 10CM.
The use of the utility model is hung on down the cofferdam on the suspension centre with hanging beam, slowly the riverbed face is put in the cofferdam then, arrives the riverbed face until the bottom surface, cofferdam, and the cofferdam will keep level during the below, and the bottom surface, cofferdam is inserted more than the riverbed 1M.The startup back-pressure helps and sinks to designated depth, carries out concrete back cover under water at last.
Except that the foregoing description, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
