Description

The concrete core-wall casting machine

The utility model relates to the construction machinery that dyke seepage control leaks concrete core-wall and structure foundation body of wall.

Existing rivers, the flood control by reservoir regulation dike has many earth embankment earth dams that still belong to, because of seepage, factors such as piping cause the accident of breaching a dyke easily, optimum reinforcing mode is the concreting core-wall, its construction machinery has multiple, adopt the high-pressure rotary jetting apparatus construction as Japan, Germany adopts the construction of wall formula excavator, China then adopts mostly and takes the mode that mould waters core-wall behind the heavy excavation and construct, owing to adopt above machinery to exist the construction earth volume big, progress is slow, it is discontinuous to construct, the cost height, or construction is complicated, such-and-such shortcomings such as anti-permeability difference, China utility model patent ZL92210082.9 discloses a kind of concrete anti-seepage plate construction equipment, it mainly is made of the groover and the slurry filling machine of band grooving saw, earlier earth embankment is slotted during its construction, injecting cement paste from bottom land again ejects groove mud, cement paste solidifies the back and forms core-wall, the use of this device greatly reduces earth volume and construction cost, speed of application increases, has certain antiseep effect, but still there is following defective: the one, grooving saw is consuming time oversize from tilting to this process of vertical ground before the fluting, add section construction, slip casting is discontinuous, makes integral construction speed still slow excessively; The 2nd, connect by clay between each section core-wall and reduced the whole leakage performance of core-wall; The 3rd, cement paste is poured into a mould not tamping, easily produces the shrinkage crack after solidifying, and influences strength of wall body and barrier performance.

It is little that the purpose of this utility model provides a kind of earth volume, and core-wall can water a jar not segmentation continuously, speed of application is fast, construction costs is low, core-wall leakage performance height, concrete core-wall casting machine simple to operate.

For realizing above purpose, technical solution of the present utility model is that described concrete core-wall casting machine comprises crawler type internal combustion car, support vertically disposed onboard chain type grooving saw, lifting gear and notes concrete device, behind grooving saw, establish " worker " font side wall backplate; The internal combustion car is established the vehicle bridge lead arm, two arms and front beam about it comprises, the grooving saw hydraulic support of supporting grooving saw and side wall backplate and side wall backplate support one in front and one in back be vertically fixed on the vehicle bridge lead arm about on two arms, also be provided with grooving saw and side wall guard plate apparatus on two arms, grooving saw turning cylinder two supports in the hydraulic stem of grooving saw hydraulic support to realize the lifting of grooving saw, be provided with the sprocket wheel that drives the saw chain transmission in the middle of the turning cylinder, turning cylinder links to each other with arm internal combustion engine moving force mechanisms by the two-stage linked transmission.

Above-mentioned grooving saw is that the digging cutter jagsaw band chain with the band saw tooth is connected into saw chain, forms a chain and sprocket driving device with the drive sprocket at the carrying rod two ends of band expansion coupling, carries and is furnished with a plurality of guide wheels between excellent forward direction and saw band.

Above the grooving saw hydraulic support, also be provided with clear earthenware just as the horizontal belt transmission, a perpendicular drive link and grooving saw turning cylinder one are terminal to be constituted the bevel gear transmission and cooperates towards dividing into for its driving wheel center, and flexible clear soil is brushed as strap lug formation in the two-wheeled groove and is similar to the bel-drivenn device.

Above-mentioned notes concrete device is by hopper, charging track, concrete tank, air compressor machine, concrete pouring pipe and be positioned at centrifugal after the side wall backplate and vibrate to hold in both hands and form.

Earlier grooving saw is placed during work and perpendicular to ground by lifting gear and grooving saw hydraulic means; Restart under the dynamical system grooving saw to depth of implements, by grooving saw positioner locking grooving saw; Side wall backplate and locking down after tens of centimeters is open to traffic and waters a jar concrete simultaneously behind the side wall plate washer before the driving, and with vibrator that concrete vibrating is closely knit.

Continuous sharp work when adopting the concrete core-wall casting machine construction of above technical scheme the time to realize grooving and concrete casting, the core-wall of building does not have seam continuously, vibrate through vibrator and to make the fine and close intensity height of core-wall, the core-wall whole impermeable is good, efficiency of construction improves greatly, and cost then greatly reduces; Whole construction course labour intensity is low in addition, and operation control is easy.

Below in conjunction with accompanying drawing the novel specific embodiment of this reality is described in further detail.
