Description
Technical field
It the utility model is related to a kind of water conservancy projects temporary construction cofferdam, more particularly to a kind of timber cofferdam.
Background technology
Publication No. CN204139185U Chinese patent discloses a kind of river course slope protection cofferdam, it is characterised in that it is wrapped
The pile foundation that two rows of left and right are longitudinally arranged is included, is provided with the connection steel wire that bending is set in pile foundation from front to back, connects steel wire by phase
Adjacent timber and piling bar connection, the top outer of pile foundation are provided with the purlin wood being longitudinally arranged, are provided with the inside of pile foundation vertical
To the splash guard of arrangement, the campshed base of left and right two is equipped with waterproof cloth from the top down, waterproof cloth be close to pile foundation the left and right sides and
Riverbed face between the campshed base of left and right two, is connected with more taut wires between the campshed base of left and right two, between the campshed base of left and right two
Waterproof cloth on be provided with and banket.
The pile foundation in above-mentioned cofferdam is smooth timber, when being impacted and rocked in cofferdam, the portion in timber insertion soil
Partial volume produces gap easily during rocking between the soil of timber and riverbed bottom, timber can gradually deviate from soil due to buoyancy
Earth, during the use of cofferdam, because of situations such as flood tide, cofferdam can be often subject to impact, and cofferdam service life is shorter.
Utility model content
The purpose of this utility model is to provide a kind of timber cofferdam, and it has the long advantage of service life.
Above-mentioned technical purpose of the present utility model technical scheme is that：
Timber and the beam being fixed on timber in a kind of timber cofferdam, including insertion riverbed, the lower end of the timber is set
Taper is set to, the inboard of the timber is provided with dividing plate, and plain soil is filled between the dividing plate, the lower end edge timber of the dividing plate
Inboard insertion river bed, the timber side offer reinforcing breach, and the reinforcing breach includes baseplane and ramp.
By using above-mentioned technical proposal, the timber with reinforcing breach is when inserting soil, the side of ramp and timber
Face contacts friction with soil, and ramp has the active force squeezed to both sides to soil so that the insertion of timber is more smooth.Wood
Behind stake insertion bottom, due to the soil of top or the extruding at noon, have soil and enter in reinforcing breach.Timber is rocked
When, the soil having with surrounding ground one is reinforced on the baseplane of breach, and the rising to timber stops, while timber exists
Rock in uphill process, baseplane contacts with soil, and resistance is more preferable relative to frictional force blocking effect perpendicular to baseplane, carries
The structural stability of high timber cofferdam, improve the service life of timber cofferdam.
Further set：The reinforcing breach is set in a ring.
By using above-mentioned technical proposal, the convenient processing of reinforcing breach that annular is set, and all directions active force phase
Deng when mounted, easier for installation without adjusting installation direction.
Further set：The dividing plate is formed by thin bamboo strips used for weaving and reinforcing bar colligation.
By using above-mentioned technical proposal, thin bamboo strips used for weaving has stronger toughness, and it is stronger to bear the ability of pressure, but structural strength
Relatively low, during water impact, edge is easily damaged, by reinforcing bar colligation in the end of thin bamboo strips used for weaving so that impulse force directly with
Reinforcing bar acts on, and reduces the abrasion of thin bamboo strips used for weaving, improves the intensity and service life of dividing plate.
Further set：The hook being provided with the dividing plate on the beam hung over, the welding hook is in dividing plate
On reinforcing bar.
By using above-mentioned technical proposal, the hook hung on beam is provided with dividing plate, conveniently to position during installation
It is determined that while when dividing plate bears ambient pressure, hook can produce pulling force to dividing plate, avoid dividing plate and timber from departing from, improve every
The stability of the connection of plate.
Further set：One layer of geotextiles are equipped with the dividing plate, mud face is stretched into the lower end of the geotextiles from both sides
At least 1m.
By using above-mentioned technical proposal, geotextiles are protected to the plain soil between dividing plate, avoid plain soil from passing through dividing plate
It is lost in, ensures the Stability Analysis of Structures of timber cofferdam, service life length.Mud face is stretched into the lower end of geotextiles, to plain soil in encirclement shape
Structure, stop that protecting effect is stronger.The intensity of geotextiles is higher, and enough intensity can be kept under dry and wet state；It is corrosion-resistant,
It is antimicrobial, it is less likely to be damaged in use.
Further set：The beam passes through on binding reinforcing bars to timber.
By using above-mentioned technical proposal, beam is installed by way of binding reinforcing bars, is connected firmly, and beam connects
Timber interfixed, avoid single timber run-off the straight or deviate from soil situation.
Further set：Pass through reinforcing bar drawknot between beam described in both sides.
By using above-mentioned technical proposal, two seat side rails pass through reinforcing bar drawknot so that the distance between two seat side rails are kept
It is constant, so as to avoid the situation of the timber run-off the straight of one side failure.
Further set：The top end cover of the dividing plate is provided with packeted soil.
By using above-mentioned technical proposal, the top of dividing plate is arranged at using packed figure so that dividing plate and timber upper end
Gravity is bigger so that what dividing plate and timber can be more stable is inserted in soil, improves structural stability, also avoid geotextiles with
Occur to tilt between dividing plate to depart from.
In summary, the utility model has the advantages that：
1st, the side of timber is provided with the reinforcing breach of annular so that fixation of the timber in soil is more firm, avoids wood
Stake loosens；
2nd, a large amount of reinforcing bars are connected with overall dividing plate and beam, improve overall construction intensity, service life length.
