Reinforced concrete support 1；
It is arranged at the splitting hole 2 on described reinforced concrete support。At this, for reducing boring amount during reinforced concrete support Demolition Construction, carry out the burying work beforehand in part splitting hole when concrete support waters and smashes construction, conveniently subsequently through splitting hole, described reinforced concrete support is carried out splitting and remove。It addition, the position cleaving hole and quantity on described reinforced concrete support can be determined through calculating according to the intensity of described reinforced concrete support and quantity of reinforcement。
Preferably, as in figure 2 it is shown, described splitting hole 2 is formed by the tubing 3 being embedded in advance in described reinforced concrete support 1, described tubing one end open, the other end is closed。
Preferably, described tubing is hollow hard paper tube。It is also preferred that the left the external diameter of described hollow hard paper tube is 4cm。
Preferably, as in figure 2 it is shown, the blind end of described tubing is taper, facilitates tapering point insertion just to water and smash in complete reinforced concrete support。
Preferably, as in figure 2 it is shown, the 75% of the thickness that the length of described tubing is described reinforced concrete support。Concrete, as in figure 2 it is shown, utilize the commerical ready-mixed concrete used by reinforced concrete support to have this feature of very strong mobility, after concreting, by technical parameters such as the splitting pitch-row of hole designing requirement, array pitch, angle, the degree of depth, insert just to have watered by tubing and smash in complete concrete and fix。The hollow hard paper tube that pre-buried tubing can adopt external diameter to be 4cm。The length L of tubing matter determines according to reinforced concrete support thickness, is generally the 75% of reinforced concrete support height H。
The present embodiment passes through reinforced concrete support；It is arranged at the splitting hole on described reinforced concrete support, boring amount during reinforced concrete support Demolition Construction can be reduced, carry out the burying work beforehand in part splitting hole when concrete support waters and smashes construction, conveniently subsequently through splitting hole, described reinforced concrete support is carried out splitting and remove。
Embodiment two
The present invention also provides for the method for dismounting of another kind of reinforced concrete support, and described reinforced concrete support adopts the reinforced concrete support structure described in embodiment one, and described method includes:
Step S1, as shown in Figures 3 and 4, carries out segmentation division to reinforced concrete support 1；Before removing reinforced concrete support, first carry out the segmentation to reinforced concrete support to divide, restriction due to on-the-spot place and traffic, reinforced concrete support adopts the method for piecemeal cutting handling, preferably, after segmentation, the Weight control of every section of reinforced concrete support is within 8 tons, as shown in Figures 3 and 4, is the one section of reinforced concrete support 1 divided between each two segmentation markers 4；Preferably, before step S1, also include: adopt the mode of on-the-spot Drilling to increase splitting hole on reinforced concrete support, specifically can by technical parameters such as the splitting pitch-row of hole designing requirement, array pitch, angle, the degree of depth, Drilling is carried out in reinforced concrete support relevant position, increase splitting hole when realization needs, facilitate the purpose of follow-up dismounting；
Step S2, removes the foreign material in splitting hole；
Step S3, the super high pressure oil that hydraulic splitting machine is exported by pumping plant is adopted to drive oil cylinder, produce huge motive force the splitting hole acting on one section of reinforced concrete support after mechan-amplifier, reinforced concrete brace is made to split by predetermined direction, thus creating condition easily for the construction of rear hydraulic pincer；
Step S4, assemble hydraulic pincer on board a dredger, described hydraulic pincer is adopted to be caught broken by the concrete of this section of reinforced concrete support, make reinforcing steel bars exposed, concrete, concrete is after splitting, internal structure is loosened, hydraulic pincer is adopted to be caught broken by concrete, reinforcing steel bars exposed, it is beneficial to subsequent construction, when disintegrating forceps crushes, special messenger is sent to command, oppose when preventing mechanical execution from advancing stanchion, wall steel bar damages, preferably, before step S4, also include with fork truck hold this section of reinforced concrete support or the bottom of this section of reinforced concrete support adopt set up framed bent；
