Description

Technical Field

[0001] The utility model relates to the field of construction engineering, and particularly relates to a construction device for reducing the water content of filled soil. Background Art

[0002] In the process of filling in construction engineering, cohesive soil is a common type of soil, and its water content directly affects the filling quality.

[0003] For over-wet soil with a high water content, generally the sun-drying method is adopted. The main process of sun-drying is as follows: After the over-wet soil is dug out from the soil pit, it is piled beside the pit for preliminary sun-drying, and then transported to the construction operation section for paving; or after being dug out from the soil pit, it is first transported to one side of the operation section, and after preliminary sun-drying, it is pushed to the operation section by a bulldozer. However, since the sun-drying process after piling generally only targets the soil moisture on the outer layer of the soil pile, the internal moisture evaporates slowly. Therefore, after paving to the construction operation section, it still needs to go through a period of secondary sun-drying, and the overall time-consuming is long, which cannot meet the requirements of large-scale and continuous operation.

[0004] Therefore, a construction device for reducing the water content of filled soil is proposed to accelerate the evaporation of the internal moisture of over-wet soil and shorten the sun-drying time. Content of the Utility Model

[0005] The utility model provides a construction device for reducing the water content of filled soil, which solves the problem that the existing sun-drying process of over-wet soil takes a long time and cannot meet the requirements of large-scale and continuous operation.

[0012] Particularly, a number of air plates are also provided inside the hot air box. The hot air box is divided by the air plates into a number of vertical air ducts with equal cross-sectional areas, and the vertical air ducts correspond to the electric auxiliary heating tubes one by one.

[0013] Particularly, a retaining plate inclined towards the ground outside the soil turning box is also provided at the lower end of the side wall at the tail of the soil turning box.

[0014] Particularly, a wavy soil leveling groove is provided at the bottom of the retaining plate.

Detailed Embodiments

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems solved, the technical features constituting the technical solutions, and the technical effects brought.

[0022] As Figure 1 , Figure 2 and Figure 3 shown, a construction device for reducing the water content of filling soil includes:

[0023] A vehicle body 1 with a mounting frame 2 provided at the tail;

[0024] A soil turning box 3 hinged to the lower end of the tail of the mounting frame 2, with a rotary tiller blade group 4 rotatably provided on the inner wall of the lower part and extending out of the bottom of the soil turning box 3, and a horizontal drive motor 5 provided on the outer wall of the lower part, and the drive motor 5 drives the rotary tiller blade group 4 to rotate;

[0025] The hot air box 6 is fixed to the top of the soil-turning box 3, communicates with the soil-turning box 3 at the bottom, has an opening at the top, a horizontal fan 7 is fixed in the opening, and a number of horizontal electric auxiliary heating pipes 8 are also provided on the side wall of the hot air box 6 below the fan 7;

[0026] The hydraulic cylinder 9 is hinged at one end to the upper end of the tail of the mounting frame 2 and at the other end to the upper surface of the hot air box 6.

[0027] In the present utility model, the main working process is as follows: Move the device of the present utility model to the soil material yard where the water content needs to be reduced. Adjust the angle of the hot air box 6 through the hydraulic cylinder 9, and then drive the vertical position of the rotary tiller blade group 4 at the bottom of the soil-turning box 3 to be adjusted, so that it is embedded in the soil at an appropriate depth. Start the vehicle body 1, so that the vehicle body 1 moves at the required position, thereby driving the rear soil-turning box 3 to move, and turning and loosening the filling material through the rotary tiller blade group 4. At the same time, blow air into the soil-turning box 3 through the fan 7 in the hot air box 6, and use the electric auxiliary heating pipe 8 to heat the air flow, so as to ensure that the hot air can evenly blow on the soil turned up by the rotary tiller blade group 4, raise the temperature of the over-wet soil, and cooperate with the hot air to accelerate the air flow rate, thereby effectively accelerating the evaporation of the internal moisture. During the whole process, the mechanical soil-turning process of the rotary tiller blade group 4 can also help to break the soil compaction, effectively increase the air permeability and surface area of the soil, and is beneficial to the rapid evaporation of subsequent moisture.

[0028] As a preferred embodiment, the rotary tiller blade group 4 includes a rotating shaft horizontally arranged on the inner wall of the lower part of the soil-turning box 3, and a number of rotary tiller blades are provided on the rotating shaft; the output shaft of the driving motor 5 penetrates the side wall of the soil-turning box 3 and then is connected to the rotating shaft.

[0029] In this embodiment, a specific structure of the rotary tiller blade group 4 is provided. Among them, the rotating shaft is the main component of the whole structure, transmits the rotation output by the driving motor 5 to the rotary tiller blades, so as to drive the rotary tiller blades to rotate and perform soil-turning operations on the soil below. And multiple rotary tiller blades can ensure the uniform soil-turning of the soil below, guarantee the soil-turning effect, and are also beneficial to the process of breaking the soil compaction.

[0030] As a preferred embodiment, a number of air plates 10 are also provided in the hot air box 6, and the hot air box 6 is divided into a number of vertical air ducts with equal cross-sectional areas by the air plates 10, and the vertical air ducts correspond to the electric auxiliary heating pipes 8 one by one.

[0031] In this embodiment, by arranging wind plates 10 inside the hot air box 6, the hot air box 6 is divided into multiple vertical air ducts, and the electric auxiliary heating tubes 8 are arranged in each vertical air duct. On the one hand, it can make the air volume in each area below the soil-turning box 3 consistent, and the overall water evaporation volume consistent. On the other hand, it can also ensure that the hot air temperature in each vertical air duct is roughly the same, avoiding the problem of uneven soil properties caused by inconsistent water content in each part of the filled soil.

[0032] As a preferred embodiment, a retaining plate 11 inclined towards the ground outside the soil-turning box 3 is further provided at the lower end of the side wall at the tail of the soil-turning box 3.

[0033] In this embodiment, a retaining plate 11 is arranged at the tail of the soil-turning box 3. By arranging the retaining plate 11, the soil turned out by the rotary tiller group 4 will not splash, ensuring the uniformity of the paved soil layer.

[0034] As a preferred embodiment, as Figure 4 shown, a wavy soil-levelling groove 12 is provided at the bottom of the retaining plate 11.

[0035] In this embodiment, by arranging a wavy soil-levelling groove 12 at the bottom of the retaining plate 11, the shape of the surface layer of the filled soil after passing through the soil-levelling groove 12 is generally wavy as a whole, thereby increasing the surface area of the filled soil surface layer and accelerating water evaporation.
