The junction block has bayonet joint in the end for connection with other junction blocks, inside floating tank cavity and mortar pipe, and movable valve in the bottom. The junction block in the said structure may be assembled and disassembled easily, and has good stress condition, high sealing performance and diameter of 1000-1200 mm. The present invention has maximum drawing force of 450 ton and maximum operating depth of 100 m.
Description
Technical field
The present invention relates to the drawbench that a kind of impervious wall engineering is used, particularly a kind of large full hydraulic pipe drawing machine.
Background technology
Carry out in the impervious wall construction process at basis, seepage prevention of cofferdam dam, impervious wall nipple orifice construction technology is the key factor that wall section quality of connection guarantees, along with the hydroelectric development great development, the degree of depth of impervious wall engineering has surpassed 70m, more than 100m, challenge, the thickness of body of wall is also all at 0.8～1.2m, in order to satisfy dam foundation deformation and requirement of strength, materials for wall is main direction with the high strength, low elasticity new material, and existing drawbench can't satisfy construction requirement aspect the straight warp of junction block, the hole depth.
Summary of the invention
The objective of the invention is to provide a kind of large full hydraulic pipe drawing machine, and it can overcome existing drawbench and work that the ability of pulling out is little, the junction block diameter is little, and the deficiency of depth as shallow meets and the degree of depth surpassed more than the 50m construction requirement of the impervious wall of thickness 1.0m～1.2m.
The object of the present invention is achieved like this: a kind of large full hydraulic pipe drawing machine, comprise junction block 2, mainframe 1 and hydraulic control system, be provided with the jacking oil pump in the hydraulic system, hold oil pump tightly, clamp oil pump and fine motion oil pump, one end side surface of junction block 2 is provided with arc clip key 6, one end correspondence of another coupled junction block 2 is provided with tongue and groove 4,5, connecting between the junction block 2 is arc clip key 6 and corresponding tongue and groove 4,5 connection, the link of arc clip key 6 one ends is fixing, the other end is installed back nut at junction block 2 and is fixed, be provided with buoyancy tank cavity 7 and logical slurry pipe 8 in the junction block 2, Movable valve 10 is arranged at the junction block bottom, and the diameter of junction block 2 is 1000mm～1200mm.
Connection is that the arc clip key that is evenly distributed on pipe week is stuck in the groove of corresponding joints between junction block owing to adopting in the present invention, joint is special steel casting, so it is simple in structure, be convenient to dismounting, stress condition is good, and closure is good, prevents that joint breaking and concrete from entering in the pipe, the big I of junction block is according to the thickness needs of impervious wall, and diameter can be in the 1000---1200mm scope; Again because buoyancy tank cavity and logical slurry pipe are set in the junction block, through mechanical calculation, reach and can utilize factor balances such as overcoming buoyancy, resistance lifting under mud, the coxopodite pipe is provided with valve and builds at concrete and can avoid concrete to enter in the pipe in the process, and junction block connects easy, easy row, stable.The specified maximum pulling force 450t of the present invention, construction depth capacity 100m.
Description of drawings
The invention will be further described with implementing side below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 1 double as Figure of abstract.
Among the figure: 1, mainframe, 2, junction block, 3, joint, 4, groove, 5, tongue, 6, the arc keyway, 7, the buoyancy tank cavity, 8, logical slurry pipe, 9, dividing plate, 10, pipe end valve.
The specific embodiment
As shown in Figure 1, a kind of large full hydraulic pipe drawing machine, comprise junction block 2, mainframe 1 and hydraulic control system, be provided with the jacking oil pump in the hydraulic system, hold oil pump tightly, clamp oil pump and fine motion oil pump, one end side surface of junction block 2 is provided with arc clip key 6, one end correspondence of another coupled junction block 2 is provided with tongue and groove 4,5, connecting between the junction block 2 is arc clip key 6 and corresponding tongue and groove 4,5 connection, the link of arc clip key 6 one ends is fixing, the other end is installed back nut at junction block 2 and is fixed, be provided with buoyancy tank cavity 7 and logical slurry pipe 8 in the junction block 2, Movable valve 10 is arranged at the junction block bottom, and the diameter of junction block 2 is 1000mm～1200mm.
Operating principle of the present invention is: realized modes such as jacking is held tightly, clamps, unclamped, fine motion by hydraulic way control oil cylinder, make junction block divide into and rise and pull out, finally form nipple orifice.
The junction block 2 usefulness steel plates of drawbench are made, interior welded closure steel plate forms buoyancy tank cavity 7, the logical slurry of middle welding steel pipe 8, and joint is special steel-casting, one end is cast tongue and groove 4 and 5, one ends and is cast the round of 3 arc clip keys 6 can be installed and snap in the groove by 3 arc clip keys and connect.Around the junction block 2 mainframe 1 is arranged, 4 tops is set on the mainframe stretches oil cylinder, hold oil cylinder and 1 clamping cylinder tightly for 2, by the jacking of hydraulic control system control oil cylinder, hold tightly, work such as clamping, fine motion, the lifting sub pipe.The tube drawing initial stage, adopt the fine motion hoisting way, fine motion promotes in the concrete coagulation process, avoids the generation of concrete cast tube phenomenon; In the bottom of coxopodite junction block 2 a fan pipe end valve 10 is arranged, pipe end valve 10 is outwards half-open, and before junction block was fallen the end, mud entered in the pipe thus, and when junction block 2 was fallen the end, pipe end valve 10 was closed, and entered in the pipe to stop concrete; The design of joint also stops concrete to enter in the pipe, the buoyancy tank cavity 7 of junction block 2 increases the buoyancy of junction block 2 in mud, it is excessive to have avoided big degree of depth junction block to divide in the process deadweight, require the big problem of hoisting power, logical slurry pipe 8 is convenient to mud and is entered in the pipe, and assurance junction block 2 is not floated and easily is lowered to put in place.
The diameter of junction block 2 can be definite according to the impervious wall thickness requirement, can be in the 1000mm--1200mm scope, and the optimum diameter of junction block is 1000mm and 1200mm, the maximum pulling force 4500KN that the present invention is specified, construction depth capacity 100m.
