[0002] During the construction of cement-stabilized gravel base, the maintenance problem of cement-stabilized gravel base in high temperature weather has a serious impact on the quality of cement-stabilized gravel base. In the past, the methods of covering with geotextiles and then sprinkling water mechanically, artificial water pipe sprinkling maintenance, etc. were used, which caused mechanical damage to the base, inadequate maintenance, uneven sprinkling, poor water retention, and was labor-intensive and time-consuming. How to efficiently, economically and high-quality reduce or eliminate the quality risks of cement-stabilized gravel base caused by mechanical damage and lack of water for maintenance during the construction and maintenance of municipal road cement-stabilized gravel base under high temperature conditions is a difficult problem.

[0003] The present invention belongs to the field of technical research and application research on construction quality and stability of flexible pavement structures under high-humidity and high-heat coupling conditions, and specifically relates to a high-efficiency maintenance method for cement-stabilized gravel base layers, which utilizes a construction and maintenance device for cement-stabilized gravel base layers of municipal roads in high-temperature weather. During the base layer maintenance process, the high temperature weather causes water shortage in the cement-stabilized gravel base layer, and the back-and-forth rolling of the maintenance sprinkler machinery causes the structure to become loose, which has a great influence on the initial strength formation of the cement-stabilized gravel base layer. The method is simple to operate, safe and feasible, and has guaranteed quality. It can greatly save the expenditure costs caused by water shortage and rolling of the maintenance machinery during high-temperature maintenance of the cement-stabilized gravel base layer, and improve the quality of the cement-stabilized gravel base layer.

The device is divided into four parts: a geotextile water-retention layer, a polyethylene water pipe, a reserved connection port for the water pipe, and a polyethylene water-sealing layer, which are bonded to form a covering of moderate thickness. The fifth part is a water-supply hole provided on the water pipe of the device, which replenishes water into the geotextile water-retention layer during the maintenance of the cement-stabilized gravel base layer.

[0008] The water retention of the covering device is ensured by the geotextile water-retention layer, so that the covering material can be better kept moist during the curing process; the toughness and water transport capacity of the polyethylene water distribution pipe can better protect the cement-stabilized gravel base from the effects of water shortage during curing; the reserved connection port of the water distribution pipe is used to connect the water supply pipe and multiple covering device units, so as to ensure that the cement-stabilized gravel base in the covered area has sufficient water for curing. At the same time, the easy disassembly and assembly performance makes it suitable for curing areas of any size and recycling of the device during curing of cement-stabilized gravel; the water-sealing performance of the polyethylene water-sealing layer and the water supply holes provided on the water distribution pipe ensure that only a very small amount of water in the cement-stabilized gravel base evaporates, reducing the adverse effects of rapid water evaporation and back-and-forth rolling of sprinkler trucks during ordinary watering and curing of cement-stabilized gravel base under high temperature conditions; the water-locking structure formed by the five parts of this device can realize the functions of preventing the cement-stabilized gravel base from being rolled by sprinkler machinery during construction and curing in high temperature weather, preventing water shortage, facilitating connection and assembly, and recycling, thereby reducing the impact of factors such as high temperature weather and damage from sprinkler machinery on the structure and quality of the cement-stabilized gravel base;

[0009] After the cement-stabilized gravel base is constructed in hot weather, the device is placed over the concrete surface. The geotextile water-retention layer ensures the water retention of the covering device, allowing the covering to remain moist during curing. The toughness and water-transfer capacity of the polyethylene water pipe effectively protect the cement-stabilized gravel base from water shortages during curing. The reserved connection port of the water pipe is used to connect the water supply pipe and multiple covering device units, ensuring that the cement-stabilized gravel base within the covered area has sufficient water for curing. The device's ease of disassembly and assembly makes it suitable for curing areas of any size and for recycling. The water-sealing properties of the polyethylene water-sealing layer and the water-replenishing holes provided on the water pipe ensure minimal evaporation of water from the cement-stabilized gravel base, reducing the adverse effects of rapid evaporation and mechanical compaction during conventional watering and curing of the cement-stabilized gravel base under high temperature conditions.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 The present invention provides a technical solution: a high-efficiency maintenance method for cement-stabilized crushed stone base.

[0020] It is composed of five parts in total. The device is divided into four parts: geotextile water-retention layer, polyethylene water pipe, reserved connection port for water pipe, and polyethylene water-sealing layer. The four parts are glued together to form a covering of moderate thickness. The fifth part is the water supply hole set on the water pipe of this device, which replenishes water into the geotextile water-retention layer during the maintenance of the cement-stabilized gravel base. The geotextile water-retention layer has strong water retention, the polyethylene water pipe has the function of timely replenishing water, the reserved connection port for water pipe has the function of connecting the water supply pipe and multiple covering device units, the polyethylene water-sealing layer has a strong water-sealing effect, and the water supply hole has the function of timely replenishing water in the geotextile water-retention layer. The five parts form a water-locking structure, which realizes the functions of preventing damage caused by the back-and-forth rolling of the sprinkler machinery during the maintenance of the cement-stabilized gravel base, preventing water shortage maintenance, facilitating connection, and recycling, so as to achieve efficient maintenance of the base and improve the quality of the base.

[0021] The water retention of the covering device is ensured by the geotextile water-retaining layer, so that the covering material can be better kept moist during the curing process; the toughness and water transport capacity of the polyethylene water distribution pipe can better protect the cement-stabilized gravel base from the effects of water shortage during curing; the reserved connection port of the water distribution pipe is used to connect the water supply pipe and multiple covering device units, so as to ensure that the cement-stabilized gravel base in the covered area has sufficient water for curing. At the same time, the easy disassembly and assembly performance makes it suitable for curing areas of any size and recycling of the device during curing of cement-stabilized gravel; the water-sealing performance of the polyethylene water-sealing layer and the water supply holes provided on the water distribution pipe ensure that only a very small amount of water in the cement-stabilized gravel base evaporates, reducing the adverse effects of rapid water evaporation and back-and-forth rolling of sprinkler trucks during ordinary watering and curing of cement-stabilized gravel base under high temperature conditions; the water-locking structure formed by the five parts of this device can realize the functions of preventing the cement-stabilized gravel base from being rolled by sprinkler machinery during construction and curing in high temperature weather, preventing water shortage, facilitating connection and assembly, and recycling, thereby reducing the impact of factors such as high temperature weather and damage from sprinkler machinery on the structure and quality of the cement-stabilized gravel base;

[0022] After the cement-stabilized gravel base is constructed in hot weather, the device is placed over the concrete surface. The geotextile water-retention layer ensures the water retention of the covering device, allowing the covering to remain moist during curing. The toughness and water-transfer capacity of the polyethylene water pipe effectively protect the cement-stabilized gravel base from water shortages during curing. The reserved connection port of the water pipe is used to connect the water supply pipe and multiple covering device units, ensuring that the cement-stabilized gravel base within the covered area has sufficient water for curing. The device's ease of disassembly and assembly makes it suitable for curing areas of any size and for recycling. The water-sealing properties of the polyethylene water-sealing layer and the water-replenishing holes provided on the water pipe ensure minimal evaporation of water from the cement-stabilized gravel base, reducing the adverse effects of rapid evaporation and mechanical compaction during conventional watering and curing of the cement-stabilized gravel base under high temperature conditions. The five-part water-locking structure of the device achieves the goals of preventing mechanical compaction, preventing water shortages, facilitating connection and assembly, and enabling recycling during the construction and curing of the cement-stabilized gravel base in hot weather.

[0023] like Figure 1As shown, after the construction of the cement-stabilized gravel base is completed under high temperature weather, this device is covered on the concrete surface layer. This device ensures the water retention of the covering device through the geotextile water-retaining layer ①, so that the covering material can be better kept moist during the maintenance process; the toughness and water transport capacity of the polyethylene water pipe ② make the cement-stabilized gravel base better protected from the influence of water shortage during maintenance; the reserved connection port ③ of the water pipe has the function of connecting the water supply pipe and connecting multiple covering device units, so as to ensure that the cement-stabilized gravel base in the covered area has sufficient water for maintenance as much as possible, and at the same time it is easy to disassemble and assemble. The device provides a function suitable for curing areas of any size during cement-stabilized gravel curing and for recycling the device. The water-sealing performance of the polyethylene water-sealing layer ④ and the water-supply holes ⑤ provided on the water distribution pipe promote the evaporation of only a very small amount of water in the cement-stabilized gravel base layer, thereby reducing the adverse effects of rapid evaporation of water and back-and-forth rolling of the sprinkler machine during ordinary watering curing of the cement-stabilized gravel base layer under high temperature conditions. The water-locking structure formed by the five parts contained in this device achieves the purpose of preventing the cement-stabilized gravel base layer from being rolled by the sprinkler machine during construction and curing under high temperature weather, preventing water shortage curing, facilitating connection and assembly, and recycling.

[0024] The structure and design of the present invention are reasonable, and the method of using the geotextile to cover and then sprinkle water mechanically, artificial water pipe sprinkling maintenance and other methods in the past to avoid mechanical damage to the base layer, inadequate maintenance, uneven sprinkling, poor water retention performance, and labor-consuming and time-consuming relief, thereby saving manpower and time, and achieving the purpose cleanly and efficiently; ensuring the stability of the base layer of the municipal road cement stabilized gravel base under high temperature conditions, and thus ensuring that the cracks and looseness quality problems of the cement stabilized gravel base layer caused by mechanical sprinkling maintenance and insufficient moisture in high temperature weather are controllable, thereby improving work efficiency and ensuring the quality of subsequent cement stabilized gravel base layer construction, and having great construction advantages in terms of cost saving, convenient construction, reducing the cracking of the cement stabilized gravel base layer caused by high temperature maintenance machinery, controlling the moisture content of the cement stabilized gravel base layer during high temperature maintenance, and recovering the covering material after the maintenance is completed.

[0025] In summary, the high-efficiency curing method for cement-stabilized gravel base layer ensures the water retention of the covering device through the geotextile water-retaining layer, so that the covering material can be better kept moist during the curing process; the toughness and water transport capacity of the polyethylene water pipe can better protect the cement-stabilized gravel base layer from the influence of water shortage during curing; the reserved connection port of the water pipe has the function of connecting the water supply pipe and multiple covering device units, so as to ensure that the cement-stabilized gravel base layer in the covered area has sufficient water for curing as much as possible, and the performance of easy disassembly and assembly provides the cement-stabilized gravel curing with the function of being suitable for curing areas of any size and recycling the device. The water-sealing performance of the polyethylene water-sealing layer and the water-replenishing holes provided on the water distribution pipes cause only a very small amount of water in the cement-stabilized gravel base to evaporate, reducing the adverse effects of rapid water evaporation and the back-and-forth rolling of sprinkler trucks during ordinary watering and maintenance of the cement-stabilized gravel base under high temperature conditions; the water-locking structure formed by the five parts contained in this device realizes the functions of preventing the construction and maintenance of the cement-stabilized gravel base from being rolled by sprinkler machinery, preventing water shortage maintenance, facilitating connection and assembly, and recycling in high temperature weather, reducing the quality problems of loose and cracked cement-stabilized gravel base caused by damage to sprinkler machinery due to high temperature weather factors, lack of water maintenance, and other inadequate maintenance.

[0026] Compared with the existing production methods, the advantages of the present invention are: (1) the geotextile water-retaining layer ensures the water retention of the covering device, so that the covering can be better kept moist during the curing process; (2) the toughness and water transport capacity of the polyethylene water pipe can better protect the cement-stabilized gravel base from the influence of water shortage during the curing; (3) the reserved connection port of the water pipe has the function of connecting the water supply pipe and the multiple covering device units, so as to ensure that the cement-stabilized gravel base in the covered area has sufficient water for curing, and the performance of easy disassembly and assembly provides the function of being suitable for curing areas of any size and recycling the device during the curing of cement-stabilized gravel; (4) the water-sealing performance of the polyethylene water-sealing layer and the water-supply holes provided on the water pipe promote the evaporation of only a very small amount of water in the cement-stabilized gravel base, reducing the adverse effects of rapid evaporation of water and rolling back and forth of sprinkler trucks during the ordinary covering and watering curing of the cement-stabilized gravel base under high temperature conditions, thereby achieving the purpose of preventing mechanical rolling of sprinklers, preventing water shortage curing, facilitating connection and assembly, and recycling of the cement-stabilized gravel base during construction and curing under high temperature weather.

[0027] This method is convenient to transport, simple to operate, has guaranteed quality, low cost and simple recycling. It can greatly reduce the cost of dealing with quality risks such as damage to the cement-stabilized gravel base caused by high temperature weather, mechanical crushing damage to the cement-stabilized gravel base, inadequate watering maintenance, and looseness and cracking caused by rapid evaporation of water during the construction of municipal road cement-stabilized gravel base.
