Description

A kind of deck paving of concrete is quick, microseism restructuring bankrupt

Technical field:

The present invention relates to bridge construction engineering field, particularly relate to a kind of deck paving of concrete fast, microseism restructuring bankrupt.

Background technology:

Along with the increase of existing highway bridge working life, reconstruction overhauled by the many needs of deck paving of concrete, and artificial pneumatic pick is abolished, hydraulic breaking hammer is abolished, splitting machine is abolished three kinds of modes and constructed in main employing at present. Artificial pneumatic pick is abolished to be needed in a large number manually, and efficiency is low; It is big that hydraulic breaking hammer abolishes vibration, easily the beam body of old bridge is caused damage, and some place forbids adopting; Splitting machine is abolished needs specific equipment, and cost height, efficiency is low. And above several method is after concrete is abolished, disintegrating slag dispersion is difficult to cleaning. Therefore imagination provides one method to address this problem.

Summary of the invention:

It is an object of the invention to provide a kind of invention, it is for avoiding the weak point existing for above-mentioned prior art, one is provided to utilize deck paving and beam body gradation to build, there is the feature in natural combination face, concrete cutting machine concrete cutting of mating formation becomes block, cut off reinforced mesh, reduce the cohesive force once removed, hydraulic breaking hammer is utilized to squeeze into bonding surface by the wedge shape tup after improvement, concrete of mating formation is caused to be separated with beam body, reaching the object abolished, the concrete blocks abolished adopts the shipment of fork truck monoblock. Be a kind of construction technology simply, rapidly and efficiently, to the old little constructional method of bridge shock damage.

The technical solution used in the present invention is:

A kind of deck paving of concrete is quick, microseism restructuring bankrupt, it is characterised in that, comprise the following steps:

A, according to the block size size formulated, at point ruling mated formation and release cutting on concrete.

B, artificial traction concrete cutting machine are along dividing a ruling, the vertical cutting whole into sections of concrete of mating formation.

The fragmentation of c, usage mining machine band is hammered into shape along mating formation concrete and beam body junction surface, by the dynamic concrete of mating formation of block sled, and separated concrete blocks moves side and concentrates stacking.

D, fork truck, by the concrete blocks entrucking of concentrated stacking, are transported to appointed place.

The piecemeal of described formulation is rectangular block, and its length of side is 100CM-200CM.

Described artificial traction concrete cutting machine is along dividing a ruling, the vertical cutting whole into sections of concrete of mating formation; Depth of cut to cut off reinforced mesh be advisable, control at about 2cm apart from beam body at the bottom of joint-cutting, prevent from switching to beam body.

Described usage mining machine band fragmentation hammer, along mating formation concrete and beam body junction surface, moves, by block sled, concrete of mating formation; First allowing excavator band fragmentation hammer in place, excavator to layout, retreats operation along abolishing direction along bridge; Secondly adjustment big arm of digger angle, breaking hammer head is made to be directed at mat formation concrete and beam body junction surface, wedge shape tup inclined-plane is parallel with bridge floor, start broken hammer, wedge shape tup is squeezed into bonding surface by level, causing concrete of mating formation to be separated with beam plate, every block concrete selects two point of application to squeeze into, and the concrete that can make to mat formation is separated completely with beam plate; Last excavator band fragmentation hammer stirs concrete blocks, is removed by concrete blocks, carries out next block and abolish, and separated concrete blocks moves side and concentrates stacking.

Compared with prior art, the useful effect of the present invention is:

The present invention adopts mechanized, reduces labor workload, greatly accelerates speed of application; Broken hammer level is hit and is beaten, and point of application is mainly mated formation on concrete in dismounting, and the vibrations of beam body are little, utilizes beam body to protect; The concrete removed is in block, and bridge floor, without disintegrating slag, is convenient to cleaning; Concrete blocks is concentrated and is abolished, and the mixed tiny fragments of stone, coal, etc. can use other engineerings, is conducive to energy-conserving and environment-protective; Utilizing existing mature equipment, be conducive to promoting, cost is low.

Embodiment:

Below in conjunction with accompanying drawing, by embodiment, the present invention is described in further detail:

The first step, according to the block size size formulated, divides ruling what releasing on concrete of mating formation was cut.

First concrete cutting machine concrete 3 of mating formation is adopted to be cut into bulk, size control, at about 150cm �� 150cm, makes the appropriate adjustments according to practical situation, depth of cut to cut off reinforced mesh 2 be advisable, joint-cutting 1 end, controls at about 2cm apart from beam body 4, prevents from switching to beam body 4.

Then excavator band fragmentation hammer is in place, and excavator to layout, retreats operation along abolishing direction along bridge. Adjustment big arm of digger angle, breaking hammer head is made to be directed at mat formation concrete 3 and beam body 4 junction surface, wedge shape tup inclined-plane is parallel with bridge floor, start broken hammer, wedge shape tup is squeezed into bonding surface by level, causing concrete 3 of mating formation to be separated with beam plate 4, every block concrete selects two point of application to squeeze into, and the concrete 3 that can make to mat formation is separated completely with beam plate 4.

Last excavator band fragmentation hammer stirs concrete blocks, is removed by concrete, carries out next block and abolish.

The concrete blocks 5 abolished adopts fork truck entrucking, is transported to appointed place.

In the present embodiment, the operations such as unwrapping wire, cutting, dismounting, shipment linearly arrange, and unwrapping wire is front, and cutting following closely, is then that excavator is abolished, and are finally fork truck shipments, and each procedure does not interfere with each other, and forms streamline operration, and operating efficiency is accelerated greatly.

Above-described embodiment is only the preferably enforcement mode of the present invention, and in addition, the present invention can also have other implementations. It should be noted that, under the prerequisite not departing from present inventive concept, any apparent improvement and modification all should fall within protection scope of the present invention.
