Description

Overflow dam equipment

The application is dividing an application of " composite type siltbeach dam body engineering technology ", and original applying number is 02131470.5, and the applying date is on October 16th, 2002.

Technical field

The present invention relates to irrigation and water conservancy, reclamation, water and soil conservation and agriculture environmental protection system, particularly a kind of overflow dam equipment that matches with composite type siltbeach dam body engineering technology and use.

Background technology

The flood retention overflow dam of ground, original Yu Tan dam engineering is that cement grouts structure, utilizes certain elevation, and flood is poured in the lattice weir by the igniting flood port gate.Its defective is that structure ossifys, can not flexible Application; Cost is huge, is difficult to popularize; The strictness or the absolute limitations of gathering materials on the spot and being subjected to the different landforms condition, construction area can not be expanded; The all fronts that are difficult to adapt to after newly staying the riverbed limit narrow are brushed rule down, and the raising of the logical big vast ability of restriction forces and must raise the elevation of flood dam downstream, enlarges the design width in riverbed; Particularly cause the extensively efficient utilization of irrigation and water conservancy projects and loss water and soil and effective three of irrigation to separate disconnection.

Summary of the invention

The objective of the invention is for overcoming above defective, a kind of overflow dam equipment that is provided, this equipment is made up of lock frame, brake lining and three essential parts of automatic sedimentation protection-apron.

One, the making of equipment

The lock frame utilizes the triangle fixation principle, can adopt the rod strap-on structure.Long 4 meters of balance bar, 8 centimetres of top diameters, long 2 meters of the lock leg that is connected with the balance bar termination, long 1.5 meters of another root, 7 centimetres of top diameters.It is chevron shaped that the lock leg is isosceles, twists with bifilar No. 8 iron wires and be tied to the big first side of balance bar, and lock leg top interior angle is 50 degree.Lock frame rod is answered pitch prill bubble face.

The brake lining utilization principle of holding court from behind a screen adopts the rod and the string of 6 centimetres of top diameters, and concentric reducer is alternately arranged.Each perforating is 1 at the two ends of rod, penetrates in the eyelet with No. 8 iron wires, and of iron wire is stubborn dead with rod, and the other end grows more than 1 meter, and fixing at random with lock frame leg, the brake lining width can increase and decrease as required.Brake lining length is that the size of two lock frame spacings adds 30 centimetres, is generally 2.3 meters.

Protection-apron adopts sheet and string structure, and material has waste and old sole, skin scraper-trough conveyer, rubber tire tire.And the string method is, with mould line and to draw eye some, the cutting perforating around sole.With the sole made with length arrangement, wherein the center line of delegation just in time aim at adjacent two row to and seam, with iron wire knockout and string.The area of every group of protection-apron can be 3 * 2 meters.When adopting skin scraper-trough conveyer and rubber tire tire, utilize original length and width, each line width is not insisted on identity with as far as possible, but should be consistent with the width of delegation.Also can adopt cross to arrange and string.

Two, the assembling of equipment

During on-the-spot the installation, the lock frame is installed in the riverbed in the abutment pier in igniting flood port downstream and the place ahead, shark's fin main body termination, rectangular with igniting flood port.Lock frame spacing is advisable with 1 meter.The microcephaly of balance bar is placed to stream side, trench digging is imbedded in the groundbed, and the gradient of ditch is preferably 1: 0.12 of balance bar length, and promptly lock leg one end covers 5 centimetres of balancing poles, balance bar microcephaly one end covers balance bar more than 53 centimetres, gives covering earlier below its soil layer and presses a nylon sandy soil bag.Lock leg top is fixing rod completely.

The lock frame that sand removing hole is stayed apart from the igniting flood port downstream abutment pier and 2 meters of shark's fin main body is the position at interval, is lower than 40 centimetres on igniting flood port sand setting weir, and length generally accounts for below 3% of overflow dam sluicing section length, and looks its degree of depth of the motor-driven adjusting of coarse sand number and length.The sand removing hole bottom is established rod and is gone here and there the bank sill.

Each group brake lining is fixed on the lock frame leg, the brake lining elevation of sluicing section is that sand setting height of weir journey adds igniting flood port standard water inlet elevation, wherein desilting height of weir journey is 30 centimetres, igniting flood port standard water inlet elevation is the predetermined elevation of 20 years one chance riverbed floods, that is cross weir sluicing section elevation deducts the difference more than 10 centimetres, be generally about in the of 60 centimetres, promptly the design altitude of brake lining remains on about in the of 90 centimetres.Abutment pier need be built in the overflow dam both sides, the alternative abutment pier of the abutment pier of igniting flood port and shark's fin main body wherein, and another abutment pier can be increased the brake lining elevation of two lock frame spacings.

With each the group protection-apron again continued access get up, be fixed on lock frame leg and the brake lining.The protection-apron width is determined with last with 4 times of the maximum sluicing elevation of overflow dam, drop is sluiced change the plane following current in protection-apron, generally reaches more than 3 meters.

The specific embodiment

Realizing by the following method at application flexibly of this overflow dam equipment variation performance:

1, utilizes irrigated farmland, permanent current water source method.Promptly omit sand removing hole, compress the elevation of brake lining, the brake lining face is covered the new nylon cloth of the long width of cloth, the lower edge of nylon cloth and the right and left are pressed nylon sandy soil bag along covering, and prevent not jljl circle seepage and generation erosion.

2, utilize flooding irrigation farmland method.The brake lining of the equipment of being about to is divided into two-layer up and down, the design altitude of compression lower floor brake lining as regulating brake lining, is looked the standard water requirement and the riverbed flood elevation on lattice weir with the anti-top of the trellis that is hung on of upper strata brake lining, put down the part or all of brake lining on upper strata at random, and be connected with the lower floor brake lining.Can implicate the rod of lock top of the trellis during operation.

This flooding irrigation method is applicable to also that wasteland and cultivated land are staggered to be interted district's soil silt newly developed and overflows enforcement in flakes with the thickening of cultivated land soil layer, accomplishes that the soil is newly-increased, reclamation thickening and plantation extra earning three be unified; This method is that farmland water conservancy works that the hills area, mountain area has been implemented composite type siltbeach dam are carried out " the fast filling method of having one's face covered with " basic ancillary facility is provided, and omits pouring head works and subsystem channel.

3, the urgent job practices of retaining sand bar.The wall bank materialization combination cross weir that is about to keep off the totally-enclosed overflow of sand bar replaces with overflow dam equipment, after treating that silt is flat, dismounting equipment, the section that will deposit makes up building stones wall bank abutment pier and sluicing section, can omit the earthwork construction procedures of cross weir substantially, particularly satisfy the needs of urgent construction.
