Description

The preparation method of concrete anti-skid surface and machine coordination thereof

The preparation method of a kind of concrete anti-skid surface and machine coordination thereof can provide safety traffic for the vehicle on the road, the generation of minimizing accident.For gaining in strength and frictional force on the concrete road surface.Simultaneously,, provide even tooled joint and cutting technique, belonged to the road construction work field the road surface breakage that unordered fracture caused on concrete road surface.

At present, the most of asphalt pavement that adopts of China, seriously polluted, great amount of manpower and material resources have been wasted in annual maintenance thickening.When building the concrete road surface, adopt the segmentation shrinkage joint, brooming method, rope stitch all can not reach effectively anti-skidding, are difficult to more prevent that the unordered fracture on concrete road surface is damaged.Therefore, in use existing problem always is difficult to be overcome.

The objective of the invention is to improve the intensity on road surface, the supporting machinery construction technology of being taked at anti-skidding, the anticracking on various concretes road surface.By scientific method, press physical property and chemical reaction in the concrete construction, preferred maximum anti-skid factor prevents unordered fracture breakage, calculates the joint-cutting degree of depth.Behind tooled joint or joint-cutting, reach the intensity and the damaged purpose of anti-skidding, anti-unordered fracture that strengthen the concrete road surface.

In order to realize the purpose of invention like this, the inventor takes with walking beam Cast-in-place concrete jolt ramming to be wipeed off in concrete pavement construction process, with carrying slurry rollers roll smooth-riding surface, use the vacuum dehydration method, the water absorber of air bubble film and vacuum dehydration pump, quickens construction progress at the time that quickening is solidified.And then carry out seam troweling, tooled joint machine tooled joint and cutting machine that institute cuts and adopt artificial steel stone blade, use the core-drilling machine inspection by sampling, cleaning machine cleans the seam of being cut, again with filling machine material inject stitch in.The power choring matching operation has changed manual operations in the past, has alleviated labour intensity, has improved four-five times of work efficiency simultaneously.For guaranteeing workmanship, design and produce outfitting tool voluntarily, lower engineering cost.

The standardized construction of the science operation for the building that makes the concrete road surface reaches rationally, the inventor chemically examines through for many years repetition test, demonstration, tracking sampling.Its anti-skidding tooled joint degree of depth and the joint-cutting degree of depth can adhere to specification in the design year of using, and had stood the test of time.

Characteristics of the present invention are as follows: (1) figure one be while being open to traffic construction (2) improve early stage concrete strength (3) quicken template turnover (4) shorten inter process convergence time (5) speed of application fast (6) reduce labor intensity (7) reduce quiet stop and curing time (8) saves that cement (9) usage range is big, facility are cheap (10), and facility are little, be convenient to construction and shift

The present invention is applicable to various concretes road surface, and building technology and job practices are easy to be accepted by unit in charge of construction like this, can learn this technology faster, grasps the construction main points, is convenient to promote the use of.

Construction sequence of the present invention is as follows: one, figure two be walking beam 1. 430 kilograms of vibration forces 2. vibration frequency 2850 times/minute 3. 1.1 kilowatts of powers of motor 4. 100 kilograms of weight 5. vibrate the degree of depth 200 millimeter 6. carry out 1 meter/minute of speed 7. length freely select the 8. material a aluminium alloys b channel-section steel c steel pipe d lumps of wood of beam

Improve 4 times of work efficiency with real strickling the off of walking beam than manually-operated.Two, figure three carries the slurry cylinder

After the walking beam jolt ramming, come and go rolling, make cement paste be covered in concrete surface, and play smooth effect (, be difficult for layering, peel off) than adding one deck mortar after the concreting again for good with carrying the slurry cylinder.Adopt steel pipe manufacturing 89～105 length can freely select (have stitch or seamless steel pipe all can), it is better that two ends add bearing.Three, figure four is V ₈₂The type vacuum mat is material 1.: high strength modified poly ethylene air bubble film (wear-resisting, sour, alkali, aging), paste blanket all around.3. can directly observe the suction situation by transparent membrane.Four, figure five be the suction pad figure six that rolls be vacuum pump once inhale a figure seven be vacuum pump once inhale two 1. 180 kilograms of host variables 2. vacuum 98% figure eight be vacuum pump A type 3. 50 square metres of powers of motor 4. rotating speed 1440 * 650 * 800MM figure nine are vacuum pump Type Bs

Vacuum dehydration half an hour, can inhale the moisture that the elder brother coagulates soil the inside 12-15%.Figure ten be vacuum dehydration die trial five, figure 11 be electronic or motor-driven finisher 1. smear dish diameter 800MM 2. rotating speed 45-60 rev/min 3. power of motor 4. heavily manage 70 kilograms of 5. 4 horsepowers of gasoline engine power (165F-3 type gasoline engine) for 1.1 kilowatts

Improve the closely knit quality and the performance such as wear-resistant, impervious of concrete surface.Six, figure 12 is 1. embossing machines of embossing machine (two parts): 2. combination pinch roller 15-20 sheet wide 500MM takes turns sheet diameter 200MM, and 3. machine is heavy: 180 kilograms of 4. powers of motor: 2.2 kilowatts of 5. 6. 7. length of embossing track (200 channel-section steel) of long handle (operating time): select freely that 8. gaining machine is effective, the cost costliness.Figure 13 is that gaining machine (two parts) seven, figure 14 have water tank joint cutter (little joint cutter) figure 15 that 2. 3. 4. adapted power electric of blade diameter 300-400MM of width of slit 3-8MM of the 1. maximum joint-cutting degree of depth 60NN of water tank joint cutter (big joint cutter) is arranged: 4 kilowatts; Motor-driven: 175F6.6 horsepower, gasoline engine eight, figure 16 be electronic no water tank joint cutter figure 17 be the 1. maximum joint-cutting degree of depth of motor-driven no water tank joint cutter 240MM 2. width of slit 3-8MM 3. blade diameter 700MM 4. 11 kilowatts of powers of motor 5. 500 kilograms of figure 18 of weight be that motor-driven no water tank joint cutter (side view) nine, figure 19 are waterwheel (two parts)

Waterwheel adopts little pump sump.

Improve to insert sealing that wood or steel plate cause and Uneven road and the drawback of the big bump that causes driving a vehicle, and can prevent the concrete shrinkage and the irregular cracks that produces, making it is that diamond blade figure 21 is diamond cutter φ 300-1 φ 400-1 φ 700 at joint-cutting place breaking joint (seam contracts) ten, figure 20

Figure 22 is that diamond blade φ 300-2 φ 400-2 11, figure 23 bore 1. powered maneuver of tube and sample: 5 horsepowers; Electronic: 1.5 horsepowers 2. bore diameter 110-φ 210MM 3. get the core diameter 100-φ 200MM range 600MM that 4. works

To the rigid pavement core boring sampling, the every index of its intensity is measured, and can be checked road surface actual (real) thickness etc.
