Abstract
The utility model discloses a rubber dam circulating water de-icing and anti-freezing apparatus, which comprises brake piers, a rubber dam, a submersible pump, a flexible pipe, a sparge pipe, floating rafters, a stay cable and a pump-suspending cable. The submersible pump is fixed by the pump-suspending cable arranged on the brake piers. The submersible pump is connected with the sparge pipe via the flexible pipe and the sparge pipe is fixed by the stay cable. The sparge pipe is equipped with floating rafters and water spray holes. Since the sparge pipe is equipped with the floating rafters, the sparge pipe floats in the water and is not easily invaded by cold air. The submersible depth of the sparge pipe can be adjusted in a windy day or during the power or water failure, so that the sparge pipe is prevented from freezing. The sparge pipe equipped with floating rafters is low in construction cost, convenient in construction and simple and practical in operation. In addition, the problem that a sparge pipe can not be fixed in the prior art is solved. Even when the water level changes, the sparge pipe can be maintained at the optimum position for ice breaking.
Description
Technical field the utility model relates to reservoir, the antifreeze ice breaker of gate dam, is specifically related to a kind of rubber dam recirculated water ice-melt winterized equipment.
The a lot of dash of background technology northern area, retaining gate dam need be prevented freezing destruction winter.At present, northern the greater part is still prolonged and is opened ice antifreezely with the mode of manually making a hole in the ice, and not only wastes time and energy, invests bigger, and do not reach good effect, and manual work danger is very big.Rope swing pipe formula is adopted in the water-soluble ice measure of circulation that reservoir, gate dam adopt, promptly establish wire rope and hang and carry sparge pipe, on long dam, can not use at the gate pier two ends, especially then can't lifting to the lock hole that surpasses 20m, and the lifting sparge pipe can not be adopted at 50～70m in the every hole of rubber dam.
The summary of the invention the purpose of this utility model is to avoid the deficiencies in the prior art part, a kind of rubber dam recirculated water ice-melt winterized equipment is provided, its feature is adopting floating square rafter towing sparge pipe, having solved sparge pipe can't fix, and SEA LEVEL VARIATION still can keep water pipe in the problem of optimum position that opens ice.
The utility model for the technical scheme that the technical solution problem provides is:
A kind of rubber dam recirculated water ice-melt winterized equipment, it comprises gate pier, rubber dam, submersible pump, flexible pipe, sparge pipe, floating square rafter, drag-line, suspending pump rope, submersible pump is fixed by being located at gate pier suspending pump rope, submersible pump connects by the fixing sparge pipe of drag-line by flexible pipe, and sparge pipe is provided with floating square rafter, hole for water spraying.
Through the test of many times pitch-row between 20～45cm, between the 1～4mm of position, hole,
Advantage of the present utility model is: sparge pipe floats over and is difficult for the air inrush of catching a cold in the water because of floating square rafter is installed, and as strong wind, have a power failure, cut off the water and can adjust the sparge pipe diving depth, guarantees that sparge pipe is icing.Install on sparge pipe that floating square rafter construction costs is low, easy construction, operation be simple, especially having solved sparge pipe can't fix, and SEA LEVEL VARIATION still can keep sparge pipe in the problem of optimum position that opens ice.
Description of drawings Fig. 1 is a structural representation of the present utility model.
A kind of rubber dam recirculated water of specific embodiment ice-melt winterized equipment, it comprises gate pier 1, rubber dam 6, submersible pump 5, flexible pipe 7, sparge pipe 8, floating square rafter 3, drag-line 2, suspending pump rope 4.Submersible pump 5 is fixing by suspending pump rope 4, and submersible pump 5 connects the sparge pipe of being fixed by drag-line 28 by flexible pipe 7, and sparge pipe 8 is provided with floating square rafter 3, hole for water spraying.
Adopt rubber dam recirculated water ice-melt winterized equipment, need possess certain depth condition, the general depth of water is not less than 1～1.5m, and the selection of submersible pump 5 and definite injection flow rate are to realize an anti-icing important ring, need calculating and field experiment to determine.Mud or permeation phenomenon must suitably be inhaled otherwise produce in the installation site of submersible pump 5.When operation, submersible pump 5 extracts water, enters sparge pipe 8 by flexible pipe 7, and the hole for water spraying on the water blowing water pipe 8 sprays equably, and the caliber of sparge pipe 8 needs analytical calculation, and the length of sparge pipe 8 and sparge pipe 8 connect and will suit measures to local conditions.The aperture of hole for water spraying and pitch-row and position need analysis of experiments calculate to determine, also are the keys of effect of opening ice.Between 20～45cm, between the 1～4mm of position, hole, these data will be determined according to combined factors analytical calculations such as the molten length of spray, the depth of water, water pumps through the test of many times pitch-row.
Construction and installation are the keys that adopt this technology, and the installation of water pipeline weld length and submersible pump etc. needs analytical calculation.The time of installing is also very important, installs and constructs on rubber dam, and easy damaged dam bag is installed then freezing thickening in evening.Through practice, adopt rational duct length and technological process, under on-the-spot condition, long rubber dam 6 people of 200m construct and just can finish in two days at material.
Through 5 rubber dam winter operation analyses are contrasted, adopt rubber dam recirculated water ice-melt winterized equipment to obtain good benefit, 1, economic benefit: adopt winter operation cycle of this equipment, the length that always opens ice 735m, about 8.6 ten thousand yuan of the electricity charge, 50,000 yuan of management fees, add up to 15.6 ten thousand yuan of running costs by other 20,000 yuan.Every meter winter operation takes 212 yuan/m.Adopt and manually to open ice: 160,000 yuan of labour costs, 20,000 yuan of management fees, other 20,000 yuan, labour protection and insure 40,000 yuan, the estimation running cost adds up to 240,000 yuan, as seen, adopt this technology to save winter operation and takes 35%; 2, returns of investment: install to make processing rubber dam recirculated water ice-melt winterized equipment, invest 120,000 yuan, annual 8.4 ten thousand yuan of the running costs of saving estimate that the 3rd runtime will recoup capital outlay; 3, safety benefit: traditional workman opens ice dangerous big, and condition of work is arduous, and inefficiency, takes the fine safety problem that opens ice that solved of this technology, has ensured operations staff's personal safety.
The utilization of rubber dam recirculated water ice-melt winterized equipment has improved the safety condition of engineering, frost heaving failure is the major casualty of northern aquatic building, adopt this technology, as long as manage with delicacy equipment, predict generable problem, can guarantee to build and be not subjected to freezing destruction, be on active service the phase thereby also prolonged engineering, improved the performance of project benefit, this equipment also is applied to aquatic buildings such as dash, retaining gate dam.
