Description
Technical field
The present invention relates to a kind of temporary water retaining cofferdam in river course, water areas project construction, especially with pre-stress stretching device, post, bar combination knot
Structure and inflation waterproof composite fabric make water-retaining cofferdam the prestressed light environmental protection cofferdam of band grout pipe antiseepage.
Background technology
At present, in relating to river course, water areas project construction, the traditional material structure such as the commonly used timber of temporary water retaining cofferdam, mound, geotextiles
Build, cofferdam construction by ambient conditions affected big, long in time limit, safety standard is low, major project completion after, to Temporary Cofferdam remove cleaning not in place,
Discarded object affects river course, water environment.
Summary of the invention:
In order to overcome tradition timber, mound construct temporary water retaining cofferdam by external world's execution conditions affected big, long in time limit, safety standard is low, Temporary Cofferdam
Building, tear trouble open, the discarded object that cofferdam is left over affects the shortcoming of water environment, and the present invention provides a kind of prestressed light environmental protection cofferdam, this cofferdam install and
Removing convenient and swift, cofferdam can be according to river course, status of the water area by band annulus column, prestress rope, tensioner, scalable arch bar, installation
Bar, straight-bar, dash curtain, grout pipe free splicing combine, by execution conditions affected little, the duration is short, safe and reliable, can be widely used in needs
In the various Water-related Project construction of Temporary Cofferdam dash, each parts in this prestressed light environmental protection cofferdam can be reused with independent assortment, and cofferdam is torn open
Discarded object is not produced, very environmental protection and economical and practical after removing.
The present invention solves technical problem and be the technical scheme is that two rows put on the band annulus column lower end of prestress rope and squeeze into the soil in riverbed
In, band annulus column upstream face side connects composition arch structure by scalable arch bar, and the scalable scalable anchor ear of arch bar band, mounting ring, by can
Flexible anchor ear, scalable arch bar is connected fixing with band annulus column, and the mounting ring of scalable arch bar may be inserted into mounting rod, is used for installing fixing dash
Curtain, the band annulus column side that meets water is opened groove, be may be inserted into the mounting rod connected with dash curtain, wear prestressing force in the annulus of band annulus column
Steel wire rope, the two ends of prestress rope are connected with the tensioner being fixed on the bank, provide pulling force for whole cofferdam, prevent cofferdam after tensioner tension
Sliding and topple, two rows carry annulus column straight-bar reinforcement by connection, above after bed board as make-shift bridge, on-the-spot needs can be met.Band annulus stands
Post and bar combination can repeat to extend, and two ends, cofferdam are fixed with riverbank, and the two ends of prestress rope are connected with the tensioner being fixed on the bank, dash
When curtain is installed, a part erects dash, and another part is laid in antiseepage at the bottom of riverbed, is laid in below the part dash curtain at the bottom of riverbed and can install additional
Grout pipe, the one of dash curtain setting dash part wears installation set, and another wears gas tube, and gas tube is by expansion after the valve cock inflation on top
Can support the standing portion of dash curtain, the standing portion of inflation rear water curtain becomes one can be with the elastomer of stress dash, and dash curtain leads to
Crossing installation set to be connected with mounting rod, mounting rod is fixed on band annulus column and scalable arch bar, dash curtain and mounting rod, scalable arch bar, band
Annulus column, prestress rope, tensioner, straight-bar composition overall structure, is delivered to water pressure at the fixing end on riverbed and riverbank.Deeper
Waters, band annulus column, mounting rod can be socketed increase height, fall part and guarantee that dash curtain is laid on riverbed part and can sink to river bed, then pass through
Stay cord is laid on riverbed part dash curtain and pulls open tiling antiseepage in river bed, and in the case of riverbed is grit isotonic water riverbed, dash curtain is laid
In the middle of riverbed part, install a grout pipe additional, before drawing water, first pass through grout pipe and carry out the part riverbed of the dash curtain that tiles locally being in the milk
Consolidation antiseepage.
The invention has the beneficial effects as follows: the prestressed light environmental protection cofferdam force-bearing situation using prestressing force arch structure is good, component is light, band annulus column,
Prestress rope, tensioner, scalable arch bar, straight-bar, mounting rod, dash curtain, grout pipe can be manufactured according to specification standardization, arrive
Behind scene, combination meets construction requirement, cofferdam installation, dismounting, convenient transportation as required, will not produce discarded object, and all components are reusable,
Very environmental protection and economical and practical.
