Description
Technical field
The utility model relates to water Bridge construction field, is specifically related to a kind of bottomless steel jacket box, for the construction of bridge phytal zone substructure binder, column.
Background technology
In expressway construction, often run into bridge and pass through the shallow water works area such as lake, river, and ground mulching layer is the comparatively soft geological such as mud, clay, due to the restriction of geological conditions and construction cost, be not suitable for large area and build island, to bridge substructure binder, column construction, usually adopt steel sheet pile cofferdam construction.Steel sheet-pile cofferdam is that plurality of steel plates stake is connected at bridge substructure binder, column periphery inserted to play steel sheet pile, and seam crossing adopts certain way sealing, encloses out the space that is closed water; Water in cofferdam is extracted out, bottom desilting, builds bottom concrete, form the environment of anhydrous drying, be convenient to carry out binder, column construction.Therefore the key of steel sheet pile cofferdam construction be cofferdam close water effect, another problem is construction cost.A kind of cofferdam structure conventional is at present Larsen steel sheet-pile cofferdam.Steel sheet pile that typical Larsen steel sheet-pile cofferdam adopts connects and sealing means, is that the both sides of each block plate stake are respectively equipped with U-shaped or Z-type limit, and two pieces of adjacent steel sheet piles are by U-shaped or Z-type socket, and seam crossing is smeared enough butter and carried out hermetic seal.But in practice of construction process, the stagnant water effect of Larsen steel sheet-pile cofferdam is unsatisfactory, often drainage is there is in pump process after forming cofferdam, usually need to adopt coarse sand, saw foam powder, cement to be in harmonious proportion, leak stopping conduit is set above outside the steel sheet pile that leaks, by leak stopping conduit leak stopping temper transferred to and need leak stopping place, the steel sheet pile that the inspirations such as coarse sand, saw foam powder, cement are leaked is connected in gap, strengthens stagnant water effect.In addition, adopt Larsen steel sheet pile costly, expend man-hour during construction more, add construction cost.
Summary of the invention
The purpose of this utility model is to provide the bottomless steel jacket box that a kind of construction cost is low, installation rate is fast, stagnant water effect is good.
For achieving the above object, the utility model is by the following technical solutions:
A kind of simple and easy bottomless steel jacket box closing water, described steel jacket box comprises multiple steel jacket box block section, it is characterized in that: described steel jacket box block section main body is rectangle steel template, the side welding snap close of steel form, opposite side welding tapered end, described snap close is the steel pipe that a length equals described steel form height, steel pipe walls is axially arranged with the opening passing through steel pipe walls along steel pipe; Described tapered end is the T-steel that a length equals described steel form height, and the thickness of T-steel web is less than the width of snap close upper shed, and flange width is less than the internal diameter of snap close; The tapered end of a steel jacket box block section vertically inserts in the snap close of another steel jacket box block section, and multiple steel jacket box block section connects into the steel jacket box that a cross section is rectangle; Be provided with complete for the space between tapered end and snap close inwall hermetic waterstop in described snap close, described waterstop is a flexible hose inside perfusion expansion cement slurry.
The utility model adopts bulk steel form to make steel jacket box block section, compared with common Larsen steel sheet-pile cofferdam, has easy for installation, speed of application is fast, close water method simple and easy, the advantages such as stagnant water effect is good, and greatly reduce the cost of bridge substructure subaqueous construction.Be example with the bottomless steel jacket box of construct long by 3 × wide 10m, girth 26m, adopt the utility model than adopting Larsen steel sheet pile and can save 0.5 day man-hour, cost saving more than 20,000 yuan.In reality, a bridge needs the cofferdam set to have a lot of, and calculate like this, man-hour and the expense of saving are considerable.If the utility model is applied in this area, by the huge economic benefit of generation and social benefit.
