Description

Technical Field

[0001] The invention relates to the technical field of diversion gap filling, and in particular to a road gap filling and repairing process. Background Art

[0002] Various cracks in cement pavement affect the appearance of the road and reduce the service life of the road. There are many reasons for pavement cracks, such as too much fine material in concrete, inadequate maintenance after pouring, uncompacted foundation, and problems with cement quality, which cause pavement cracks, and then cause water on the road to enter the base layer through the gaps. It is possible that the water will carry away the soil layer of the roadbed, or it may form mud with the soil layer and be squeezed out when vehicles roll over the pavement gaps, which will cause pavement damage and shorten the service life of the pavement. In today's increasingly noisy traffic, it may further deteriorate, and long-term road repair projects will cause traffic congestion, and dust during construction will pollute the environment. Repeated repairs cannot be maintained for a long time, which will increase road maintenance costs. Therefore, a road gap filling and repair process is needed to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a road gap filling and repairing process to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solutions: a road gap filling and repairing process, comprising the following steps: S1 repair preparation, S2 cutting and grooving, S3 grouting and cleaning, and S4 filling operation;

[0005] Step S1 patch preparation includes the following steps:

[0006] S11: Prepare filling and repairing tools and fillers according to the size of the road gap;

[0007] S12: Design and customize standard operation drawings according to road gaps, including cutting width and length;

[0008] S13: Draw cutting lines near the road gaps according to the drawings and carry out construction;

[0009] Step S2 cutting and grooving includes the following steps:

[0010] S21: Cut and groove the damaged gaps in the road surface according to standard operations;

[0011] S22: After cutting and grooving, dry stones are laid on the lower part of the groove, and glue is poured on the upper part;

[0012] Step S3 of caulking and cleaning comprises the following steps:

[0013] S31: Use a hot spray gun with high pressure hot air to clean the grouting groove;

[0014] S32: injecting the potting glue into the potting groove by a potting machine;

[0015] Step S4: The filling operation includes the following steps:

[0016] S41: By setting a lower sealing layer on the upper end of the glue filling layer and laying a base layer and a crushed stone layer on the upper end, the bottom support strength of the concrete layer is effectively enhanced;

[0017] S42: Laying a concrete layer on the gravel layer effectively enhances the overall strength of the road;

[0018] S43: The waterproof layer on the top of the concrete layer forms an independent waterproof partition, which can effectively block the downward flow of water accumulated on the asphalt surface layer, so that the water on the road surface cannot penetrate, achieving a good waterproof effect;

[0019] S44: An asphalt layer is placed on top of the drainage layer to ensure that it is aligned with the rest of the road surface;

[0020] S45: After the grouting operation is completed, spread dry sand, lime powder, etc. on the surface of the filling material for vibrating, compacting and smoothing during maintenance.

[0021] Preferably, the method further includes step S5 of filling and cleaning to clean the caulking after step S44.

[0022] Preferably, the specific operation of filling and cleaning in step S5 is:

[0023] Clean the surface of the filled and repaired road gaps, remove excess gravel, asphalt and other residual materials, and grind the road surface to make it smooth.

[0024] Preferably, in step S22, the grooves are cut with a width of 1.3 to 3 cm and a depth of less than 3 cm. When the groove width is 3 to 6 cm, the groove depth is 3 to 5 cm.

[0025] Preferably, the ratio of main components of the caulking glue, petroleum asphalt: petroleum resin: alkyd resin, is 2:1:0.3.

[0026] Preferably, the petroleum asphalt is composed of 50-65wt% of aggregate, 17-35wt% of aggregate, 11-19wt% of modified asphalt, 1-5wt% of stabilizer and 1-5wt% of anti-rutting agent.

[0027] Preferably, the cutting and grooving in step S22 uses a dust-free cutting machine, which operates in a negative pressure dust accumulation mode, the negative pressure condition is -0.02Mpa, and a 400-mesh filter combined with electrostatic adsorption filtration is used inside the dust accumulation device.

[0028] Preferably, in step S31, a hot spray gun with high-pressure hot air is used to clean the caulking groove, the temperature of the hot spray gun is set to 1500° C., the air source pressure is 0.2-0.5 MPa, and the caulking cleaning speed is 10 m / min.

[0029] Preferably, in step S31, a hot spray gun with high-pressure hot air is used to clean the caulking groove, the temperature of the hot spray gun is set to 2000° C., the air source pressure is 0.5-0.8 MPa, and the caulking cleaning speed is 5 m / min.

[0030] Compared with the prior art, this solution designs a road gap filling and repair process with the following features:

[0031] Beneficial effects:

[0032] (1) In this process, the grooving depth is small, which can ensure that there is enough material to ensure stretching during winter stretching. After high-temperature cleaning, the moisture in the grouting groove can be completely removed to ensure that the grouting glue is fully combined. The entire grouting process maintains high temperature operation to ensure effective bonding between the filler and the surrounding materials of the grouting groove.

[0033] (2) This process can effectively avoid cracking of the pavement structure by setting an upper sealing layer to protect the asphalt surface layer from direct sunlight, thereby effectively extending the service life of the pavement structure and achieving a long service life.
