Description

Technical Field

[0001] The utility model relates to a cement stabilization layer maintenance technology, in particular to a cement stabilization layer covering maintenance device. Background Art

[0002] During highway construction, the pavement structure consists of the subbase, base layer, and surface layer. The base layer is often laid and rolled into shape using a cement stabilizer. After the cement stabilizer is rolled, it typically needs to be maintained. During this maintenance process, woven bags of crushed stone are often used to compact the center and edges of the curing layer. In the summer, with high daytime temperatures, long sunshine hours, high evaporation, and strong winds, the curing layer can be blown away, causing curing failure. To ensure quality, construction workers must constantly cover and inspect the uncovered geotextiles during construction, increasing the number of construction workers and increasing their labor intensity. The woven bags and crushed stone used for compaction become construction waste after construction, causing waste and environmental pollution. Utility Model Content

After the curing is completed, the sealing cover is opened and the covering liquid in the plastic pipe is released through the flushing port, and the cement stabilization layer covering curing device can be recovered and reused.

[0005] The utility model is realized in this way. A cement stabilization layer covering and curing device is characterized in that: the cement stabilization layer covering and curing device is composed of a geotextile covering, a weight covering device, a weight covering and pouring port, and a weight covering and pouring sealing cover;

[0006] The covering device includes a protective film, a connecting plate, and a plastic pipe;

[0007] The re-filling port includes a filling port, a connecting ring A, and a connecting rod A;

[0008] The overfilling cover includes a sealing cover, a sealing ring, a connecting belt, a connecting rod B, a connecting ring B, and a hinge tongue;

[0009] The geotextile covering film and the connecting plate of the weight covering device are connected by mechanical compaction or adhesive.

[0010] Furthermore, the connecting plate and the plastic pipe are processed uniformly and formed in one step; the geotextile covering, the connecting plate and the protective film are connected by mechanical compaction at one time or by adhesive at one time.

[0011] Furthermore, the injection port and the connecting ring are uniformly processed and formed in one step, the injection port and the plastic tube are connected by an adhesive, and the connecting ring A and the connecting belt are mechanically connected by a connecting rod A.

[0022] The following will be combined with the Figure 1-Figure 5 The utility model is described in detail;

[0023] The utility model provides a cement stabilization layer covering maintenance device through improvement. Figure 1-Figure 5As shown: the cement stabilization layer covering and curing device includes a geotextile film for curing the cement stabilization layer, a covering device for preventing the geotextile film from being blown away by the wind, a covering injection port for injecting covering liquid into the covering device, and a covering injection sealing cover for sealing the covering injection port. The device is mainly used to solve the problem of the cement stabilization layer being blown away by strong wind and repeatedly covered during covering and curing.

[0024] The covering device includes a protective film 2, a connecting plate 3, and a plastic tube 4;

[0025] The refilling port includes a filling port 5, a connecting ring A8, and a connecting rod A9;

[0027] This cement stabilization layer covering and curing device is installed from the starting point after the cement stabilization layer is compacted. After a section of covering is completed, the sealing caps at the high and low sides of the cement stabilization layer are opened, and a covering liquid is injected into the plastic pipe through the injection port. Water is sprinkled on the covering geotextile for curing. When the next section of geotextile is laid, the next section of geotextile overlaps the previous section of geotextile by 30 cm. When overlapping, the end containing the plastic pipe is laid on the upper side of the end without the plastic pipe. The covering liquid at the overlapping joint ensures that the overlapping joint is not blown open by strong winds. After the curing time is reached, the sealing caps at the high and low sides of the cement stabilization layer are opened, and the covering liquid in the plastic pipe is released to retract the cement stabilization layer covering and curing device. It can be reused when needed.
