Description
Affiliated technical field
The utility model belongs to the bridge construction field of mechanical technique.
Background technology
In the pile foundation construction of highway bridge construction engineering, pile foundation generally adopts bored pile, runs into the situation of broken pile in the castinplace pile process unavoidably.Castinplace pile is the basis of bridge, and it directly has influence on the quality of bridge.Be not allow broken pile to exist in the pile foundation construction quality specifications, just must handle in case broken pile takes place.General processing broken pile is exactly reinforcing cage to be hung out the concrete that will pour into again come outbreak out.Handle broken pile like this and often will drop into very big man power and material, and incur loss through delay the duration.Such as the broken pile that took place in certain unit, 1.5 meters in stake footpath, dark 19.5 meters of stake, the processing broken pile was with 5 day time and lose more than 10,000 yuan; Also have two broken piles in addition, 1.8 meters in stake footpath, stake is dark all to be 44 meters, handle these two broken piles and used more than 40 day time, direct losses more than 250,000 yuan.
Summary of the invention
At existing bridging engineering broken pile processing method take a lot of work, time-consuming, need the problem of bigger investment, the utility model that a kind of bridging engineering broken pile treating apparatus that the concrete that reinforcing cage hangs out, will pour into is come outbreak out of need not is provided.The utility model is to adopt the secondary downcomer to handle the special equipment of broken pile method in the drilled pile concrete casting process.Broken pile so is difficult to continue, be because the secondary downcomer will be by the mud and the boring mud beds of precipitation, boring mud can all that has been achieved is spoiled if enter mud and precipitation in the conduit in the downcomer process, loses time, because conduit has advanced mud, the boring mud sediment still can produce broken pile.So secondary downcomer successfully, the sealing that must at first solve conduit can not brought mud and precipitation boring mud into the concrete layer when allowing it by mud layer, and remove this problem of sealing after end of conduit is entered concrete layer certain depth.
The utility model constitutes (electromagnetic shaker is adhered in order to installing in four holes of the last strip of stretcher) by conduit, conduit boots seat, conduit boots body, extension detacher, stretcher.
Conduit boots seat is welded on the conduit lower end, between conduit boots body and the conduit boots seat sealing ring is arranged, and sealing ring sticks with glue in the seal groove of conduit boots seat; Hang detacher and be made of clamping body, clamping pin, unhook spring, spring housing, jump ring, retaining pin, retaining guide, retaining pin spring, anti-sticking top board, anti-sticking spring, eyenut, bolt, stop collar, unhook tongue, unhook tongue pad circle, suspension ring spring etc., the unhook tongue is welded on the unhook tongue pad circle; Stretcher is made of wire rope, reel, support, spool shaft, handle, click.Hanging detacher is connected with buckle with the wire rope of stretcher.The connected mode of stretcher and conduit: be that flange is connected or is threaded between each section of conduit, also connect between stretcher reel base plate and the conduit in identical with it mode.
The eyenut of hanging detacher is contained on the wire rope of stretcher, and bolt passes clamping body centre bore and is connected with eyenut, and the suspension ring spring is housed on bolt successively, stop collar and unhook tongue pad circle, and the unhook tongue is welded on the unhook tongue pad circle.Clamping pin, unhook spring, spring housing and jump ring are equipped with in the bottom of clamping body, be welded with retaining guide, retaining pin, anti-sticking top board and plate washer on the spring housing, have the retaining spring on the retaining pin, and be provided with cottor pin, anti-sticking spring and packing ring are housed, the tensioning suspension ring are stuck in the cannelure of clamper.Tensioning suspension ring lower end is welded in the bottom of conduit boots, in the middle of conduit boots body and the conduit boots seat sealing ring is housed, and strains by stretcher.
The utility model is installed, conduit is kept flat on the ground, stretcher is installed in the conduit upper end, decontrol the wire rope on the reel and hang detacher, through the conduit lower end, the suspension ring of conduit boots are inserted hang the unhook body in the conduit, promote clamping pin, simultaneously the anti-sticking top board is removed to spring housing end compression anti-sticking spring, retaining pin enters unhook spring housing retaining hole, blocks the clamping pin end; With the seal groove on the straight mouthful of platform aligning conduit boots seat of conduit boots upper end, shake stretcher reel handle tensioning wire rope, sealing ring is compacted, the suspension ring spring is subjected to being compressed behind certain pressure simultaneously, conduit boots suspension ring also snap in the groove on the clamping pin, the unhook tongue is stirred retaining pin in rising, the work of anti-sticking top board is blocked ratchet with ratchet behind the stretcher tensioning wire rope.
Use the utility model to handle broken pile, the conduit top of slinging is with in the conduit boots one end fill-in well, and conduit boots surface is a smooth curved surface, during by mud and precipitation boring mud layer, impurity can not brought into the concrete layer, enter concrete layer 2-3 rice after, the conduit upper end is fixed on the reinforcing cage, prevents the conduit come-up.The stretcher ratchet opened unclamp wire rope, clamping pin is return under the effect of unhook spring, hangs detacher and breaks away from suspension ring, wire rope is regained just can be continued pour concrete.The conduit boots lose pulling force and only are subjected to buoyancy, and the concrete in the conduit constantly accumulates rising, when catheter interior pressure surpasses external pressure, separate with conduit boots seat under the pressure of conduit boots concrete in conduit, and the inside and outside concrete of conduit has just combined together.
If the broken pile position is very dark, the conduit of sealing can be subjected to bigger buoyancy, can tie up to conduit upper end with the downward tractive of manpower with coir rope, when manpower is difficult to control, can adopt machinery such as Chain block that the conduit upper end is applied pulling force, and can use simultaneously and adhere to electromagnetic shaker, make conduit reach appointed part smoothly, be fixed on the reinforcing cage and get final product.Resistance maximum when conduit enters the concrete layer can be used electromagnetic shaker when inserting conduit.
Conduit boots seat, conduit boots can be foundry goods, steel construction piece.And the conduit boots can also be made hollow body with materials such as plastics, rubber, nylon and replace steel part to reduce cost, even can form with log turning.The conduit boots that certain nonmetals are made will be regained, and can not stay in the concrete.
The utility model has changed the method for the processing of bridging in the past broken pile, it is the device that the secondary downcomer is handled the broken pile indispensability in the drilled pile concrete casting process, it is very convenient to use the utility model to handle broken pile, can save plenty of time and fund, and the utlity model has simple in structure, advantage of low manufacturing cost.
