Description

Technical Field

[0001] The utility model relates to the technical field of highway engineering, in particular to a light-weight high-strength self-compacting material filling slope control device. Background Art

[0002] In recent years, with the rapid development of the world's economic construction, the number of cars owned by residents has increased year by year, and the requirements for road capacity and comfort have been continuously improved. In order to meet the traffic needs, the total mileage of roads and the number of bridges and culverts have been continuously increased. At the same time, many expressways were built early and are mostly two-way four-lane, which have shown outstanding problems such as tight capacity, a sharp decline in service levels, and the mismatch between their scale and capacity and the tasks and roles they undertake. At this stage, they can no longer meet the needs of sustainable development of the economy, society, and urban and rural construction. Many expressways are facing the problem of reconstruction and expansion. Diseases such as "bridge jumping" and "uneven roadbed settlement" are difficult problems to be faced in the process of road construction, reconstruction and expansion, which seriously affect driving safety and driving comfort. These diseases are all caused by differential roadbed settlement. Therefore, how to slow down and eliminate differential roadbed settlement is particularly important.

[0003] Bubble light soil is a new type of lightweight cement-based environmentally friendly material that is formed by mixing and solidifying cement, admixtures, water, bubble groups and other materials in a certain proportion. It has good fluidity, hydraulic hardness, light weight and low deformation. These characteristics make bubble light soil less destructive to the old roadbed and greatly reduce the load of fill. Compared with traditional road construction materials, bubble light soil has considerable advantages in construction performance, cost, and applicability. It has been successfully used in highway roadbed widening, bridge abutment backfill, soft foundation embankment filling, landslide section embankment filling, steep and sharp turn section filling, tunnel cavity backfill and other engineering projects.

[0004] The road design process faces the problems of elevation fluctuations and road drainage. Therefore, roads usually need to be designed with certain transverse and longitudinal slopes. New materials such as bubble lightweight soil have the characteristics of self-leveling. The fillers at high places will flow to low places after pouring, making it difficult to form the designed slope. Therefore, how to control the slope of the roadbed fillers with self-leveling properties after filling is of great significance to the actual roadbed filling project. Summary of the invention

[0115] The track is set as a serial extension track. It can be serially extended according to the construction object.

[0116] The functions of the main components in this utility model are as follows:

[0117] Scraper: used to scrape the roadbed filler to make the filled roadbed present the required slope;

[0118] Track: used for fixing and moving the scraper;

[0119] Bracket: It is set as a lifting and adjusting bracket, which is connected to the track, bears the force transmitted by the scraper and the track, and can adjust the rise and fall of the track;

[0120] Connection frame: responsible for connecting various brackets and playing a role of fixed connection;

[0124] The rails, brackets and connecting rods are all provided with telescopic interfaces, which are telescopic and extendable structures.

[0125] The roadbed filler of bubble light soil has the characteristics of good fluidity, hydraulic hardness, light weight, and small deformation, and has been successfully applied to various highway, bridge and other engineering projects. However, new materials such as bubble light soil have the characteristics of self-leveling. The filler at high places will flow to the lower places after pouring, making it difficult to form the designed slope. Therefore, how to control the slope of the roadbed filler with self-leveling characteristics after filling is of great significance for the actual roadbed filling project.

[0126] In the utility model of a light-weight high-strength self-compacting material filling slope control device, the scraper is in direct contact with the roadbed filler, and is used to scrape the roadbed filler so that the roadbed filler forms the designed slope. The scraper is a wooden board, and its length (the span of two parallel tracks in the vertical direction) is 3~5m (can be changed according to actual working conditions), and the thickness is 0.01m. In order to ensure that the filler scraped off when the scraper is leveling the roadbed surface does not go over the scraper and climb over the roadbed filler area that has been leveled, the scraper should be set to a certain height. In this device, the scraper height is set to 0.2m, and the scraper is arranged at an angle of 60° with the horizontal direction of advance. When in use, the scraper is adjusted by the track through the scraper angle holder, and the scraper is used to scrape the roadbed before the filler is initially solidified to form the designed slope.

[0127] The utility model discloses a lightweight and high-strength self-compacting material filling slope control device in which the track is a retractable device. To adapt to highways of all grades, the retractable range is 10 to 25 meters (half-width paving is generally used during road construction. If the track length is not enough, it can be customized and adjusted according to the actual project). The track is a hollow steel pipe on which a track retractable interface is provided. The track length can be adjusted according to actual project conditions. A scraper placement groove is provided on the inner side of the track for fixing the scraper. At the same time, a crank is provided on the outer side of the track. The user controls the movement of the scraper by turning the crank and transmitting the gear, thereby achieving control of the roadbed slope.

[0128] The bracket in the light-weight high-strength self-compacting material filling slope control device of the utility model is a retractable bracket, which is made of steel and is provided with a bracket telescopic interface and a control knob, and the bracket height can be adjusted to adapt to different terrain conditions. The bracket height range is set to 1-3m. A track fixing piece is provided inside the bracket to fix the track. At the same time, the user can adjust the track placement height. By setting different track placement heights (four brackets), the angle of the scraper scraping surface is changed, thereby realizing the control of the slope of the self-leveling roadbed filler. The configuration of the bracket is arranged without affecting the rotation of the crank handle.

[0129] The supporting structure in the light-weight high-strength self-compacting material filling slope control device of the utility model is a steel support, which is arranged at the bottom of the support. Each group of supporting structures is composed of 3 supporting rods, and each supporting rod is arranged at an interval of 120 degrees. After the support position is determined, the supporting structure can be propped up to fix the support and maintain the stability of the support. The supporting rod can be folded after use.

[0130] The connecting frame in the light-weight high-strength self-compacting material filling slope control device of the utility model is a connecting rod made of steel structure, arranged on the top of the bracket, connecting four brackets, and the connecting rod is consistent with the track, which is a retractable device. The connecting frame is placed separately and can be connected to the bracket when in use. Its retracting method is consistent with the track, which can ensure the stability of the bracket.

[0131] The gears in the light-weight and high-strength self-compacting material filling slope control device of the utility model are arranged on the transmission system between the track and the synchronous transmission shaft. The operator rotates the crank to realize the movement of the scraper along the track through the transmission of the two sets of gears. On the other hand, through the synchronous transmission of the synchronous transmission shaft, the synchronous translation of the entire plate is ensured when the scraper moves, thereby realizing the movement of the scraper and leveling the road surface.

[0132] The utility model discloses a lightweight high-strength self-compacting material filling slope control device in which a roller is arranged at the bottom of a bracket. After the roadbed surface is scraped flat, the support rod is retracted, and the arrangement of the roller facilitates the movement of the entire device.

[0133] The utility model may encounter rainy weather during use, and roadbed fillers such as bubble lightweight soil will have a splash reaction, and the fillers are mostly alkaline fillers, and the instrument will inevitably come into contact with them. In order to prevent the steel used in the device from oxygen absorption corrosion, the steel used in the device must be treated with anti-corrosion, such as spraying anti-corrosion coatings.

[0134] The specific use process of the utility model is as follows: determine the support points on both sides of the filled roadbed, erect the supports, and fix the supports by connecting the frame and the supporting structure. After the erection is completed, set up the track on the support, and calculate the layout height of the tracks on the four supports according to the designed slope of the roadbed (realized by the height of the track placement groove). After the track is arranged, place and fix the scraper on the track, and drive the movement of the scraper placed on the track by rotating the crank on the outside of the track, so as to control the slope of the roadbed.
