Abstract
The utility model discloses an improved quadrilateral hexahedron for revetment, which comprises support rods and bundling points and belongs to the field of river regulation works construction. Each of the support rods is divided into three equidistant parts by the bundling points and extends outwards by one third at four corner points of a traditional quadrilateral hexahedron. The improved quadrilateral hexahedron has the advantages that the extended support rods form a claw-shaped structure, thereby being beneficial to the automatic fixing of the quadrilateral hexahedron at the river bottom without easily moving.
Description
Technical field
A kind of improved shore protection of the utility model belongs to the river regulation field in the hydraulic engineering with four limit hexahedrons, especially a kind of four limit hexahedrons of special shape.
Background technology
Common river regulation method mainly comprises: jackstone, four sides hexahedron frame group, concrete hinge row and mattress etc.These engineering methods are widely used in the improvement of various bank sections, but because the pattern that adopts is different, each method all has its scope of application, in engineering practice, should correctly distinguish river course pattern and Field Characteristics, draws suitable resolution in conjunction with the economic condition analysis.When complicated condition, also can consider the method that the various engineering means mutually combine simultaneously.Riprap protection in use; To the piece stone in the certain grain size scope evenly be thrown into certain thickness block stone layer to the collapse on the bank location from the thalweg to the seashore through calculating, cover the bank, river course that is prone to avalanche comprehensively, increase its impact resistance; The poised river gesture plays bank protection effect [2].Generally speaking, jackstone thickness should be not less than 2 times of jackstone particle diameter, and The water is deep and the current fast locates to be preferably 3～4 times.In the current top-lashed action section, there are local scour hole and thalweg in the riverbed apart from the section of bank nearer (in 60～100m), should throw to thalweg; The non-stream top of meeting dashes section, and low water is steeper with descending slope, should throw to 1: 3 to 1: 4 place of the bank slope gradient, or certain deep trouth elevation place; Low water level must shore protection the time, should be looked its current, fringe conditions and collapse on the bank intensity with descending slope slow (being delayed in 1: 3), throws to certain deep trouth elevation place.
The four sides hexahedron in use; Generally be to be thrown in the offshore water with organizing the framework of tying up bunchiness more; Be built into various forms of accumulation bodies; Fluidised form changes after making current through the framework accumulation body, fluid is become washing away of bank slope dash or alluvial, thereby reach the protection embankment, stablize toe, reduce the scour hole degree of depth, become silted up to face and make the beach, control purposes such as leading the river gesture.
Concrete mattress is a kind of collect anti-impact, anti-filter in the novel bank protection structure of unitary whole formula.According to engineering experience, hinge mattress sinking shore protection is applicable to that water front is more smooth-going, bank slope is slow and more smooth section, and to row's body end to end portion need wrap up in head and handle, the forward position need add throwing piece stone town pin.Change greatly at water front, bank slope is steep and landform changes section greatly, and the bank section of guarding at existing a large amount of jackstones should not adopt, if need to adopt in these bank sections, elder generation is in addition smooth comprehensively with bank slope before the Ying Zaichen rafting body.
Mattress is to form with withy or assorted branch lace, and area is thousands of square metre a laminated structure thing.It is high to riverbed planeness and bank slope slope requirement, under row's body rock windrow should not be arranged, and requires to have enough work waters, land-based area, and row should not anchor a vessel in the district, and row's body main material is sufficient.
Relatively distinct issues are because four limit hexahedron housings can not be rushed at downstream through regular meeting by current attached to the river bed when using the four sides hexahedron, cause waste.The improvement of the utility model is just to this problem.
Summary of the invention
The utility model provides a kind of improved shore protection can avoid being rushed at downstream by current with four limit hexahedrons.Particularly comprise: pole, tie up a little, it is characterized in that: 1/3rd positions pole are tied up a little at described pole two ends.Tying up of pole o'clock just makes position, tetrahedral four angles steel pipe stretch out the top in 1/3rd positions, always have the steel pipe of several angles end to insert in the silt impulse force of opposing current after being convenient to like this in dropping into water.
Said strut lengths is 1.5m, and diameter is 0.05m.Through test of many times, pole is adopted the steel pipe of long 1.5m diameter 0.1, and two ends and centre respectively are divided into 0.5m, is convenient to throw in, and in water, can keeps stable.
Described pole two ends are welding.
Described pole is gone up welding short steel rod.Increased tetrahedral anchor holding power.
The utlity model has following advantage:
The utility model avoids making four limit hexahedrons under the effect of rushing to summit of current, to move downstream, has increased the hexahedral stability under water in four limits.

The specific embodiment
The utility model comprises: pole 1, tie up a little 2, and it is characterized in that: 1/3rd positions pole are tied up a little at described pole two ends.Tying up of pole o'clock just makes position, tetrahedral four angles steel pipe stretch out the top in 1/3rd positions, always have the steel pipe of several angles end to insert in the silt impulse force of opposing current after being convenient to like this in dropping into water.
Said strut lengths is 1.5m, and diameter is 0.05m.Through test of many times, pole is adopted the steel pipe of long 1.5m diameter 0.1, and two ends and centre respectively are divided into 0.5m, is convenient to throw in, and in water, can keeps stable.
Described pole two ends are welding.
Described pole is gone up welding short steel rod.Welding short steel rod 3 on the pole, increased tetrahedral anchor holding power.
