Simple slope brushing system for earth and rockfill dam

Abstract

The utility model relates to a simple slope brushing system for an earth and rockfill dam. The simple slope brushing system for the earth and rockfill dam comprises a slope brushing tool; the two steel wire ropes are connected to the two ends of the slope brushing tool respectively; the two pulleys are movably arranged on the travel path of the steel wire rope through a following mechanism, and pulley grooves of the pulleys are in contact with the steel wire rope; the two traction mechanisms are connected to the ends, away from the slope brushing tool, of the steel wire ropes and located on the slope top and the slope bottom of the earth and rockfill dam correspondingly. Due to the fact that the length of the steel wire rope can be flexibly adjusted according to the dam height, when a large-height earth and rockfill dam is met, slope brushing operation can be achieved only by adopting the long steel wire rope to be matched with the slope brushing tool, the pulley, the following mechanism and the traction mechanism, and therefore it is guaranteed that the construction progress is not affected. By means of the simple slope brushing system, dam body slope brushing construction can be conducted after dam body filling is completed, so that the situation that the construction efficiency is reduced due to the fact that dam body filling and dam body slope synchronous construction interfere with each other is avoided.

Description

Technical Field

[0001] This application relates to the field of earth-rock dam construction technology, and in particular to a simple slope trimming system for earth-rock dams. Background Technology

[0002] In the construction of earth-rock dams, slope trimming is an important step. Slope trimming refers to the process of adjusting and treating the slope of earth-rock dams and other dam bodies to achieve the required slope and surface smoothness.

[0003] By smoothing the slope to ensure it meets design standards, the dam's slope angle can be prevented from becoming unstable due to excessively steep slopes, thus ensuring the dam remains stable under the influence of water pressure, its own weight, and other external forces. Slope smoothing also makes the slope surface flat and smooth, facilitating the smooth drainage of rainwater and reducing rainwater accumulation on the dam surface. This reduces water erosion and extends the dam's service life. Furthermore, a flat dam surface with the required slope provides a good foundation for subsequent dam protection works, such as laying slope protection materials and installing drainage facilities, and also facilitates daily inspections and maintenance by staff.

[0004] In traditional techniques, excavators are often used in conjunction with manual labor to smooth slopes. However, due to the limited effective working radius of the excavator's robotic arm, construction is usually impossible when encountering large earth-rock dams, which affects the construction progress. Utility Model Content

[0005] To address or partially address the problems existing in related technologies, this application provides a simple slope trimming system for earth-rock dams.

[0006] To achieve the above objectives, this application employs the following technical solution:

[0007] A simplified slope trimming system for earth-rock dams, comprising:

[0008] Slope trimming tools;

[0009] Two steel wire ropes are connected to both ends of the slope brushing tool;

[0010] Two pulleys are arranged along the path of the wire rope by following the movement of the mechanism, and the grooves of the pulleys come into contact with the wire rope.

[0011] The traction mechanism is connected to the end of the steel wire rope away from the slope brushing tool. There are two traction mechanisms, which are located at the top and bottom of the earth-rock dam, respectively.

[0012] Optionally, the two pulleys are located directly above and directly below the slope brushing tool, respectively.

[0013] Optionally, the following mechanism is an excavator, and the pulley is mounted on the bucket of the excavator.

[0014] Optionally, the traction mechanism is a loader.

[0015] Optionally, the end of the wire rope furthest from the slope-scraping tool is fastened to the tail end of the loader.

[0016] Optionally, the slope-brushing tool is a flat-bottomed, weighted concrete block.

[0017] The beneficial effects of this application are as follows: Because the length of the steel wire rope in this application can be flexibly adjusted according to the dam height, when encountering a large earth-rock dam, only a longer steel wire rope needs to be used in conjunction with slope-brushing tools, pulleys, following mechanisms, and traction mechanisms to achieve slope-brushing operations, thereby ensuring that the construction progress is not affected. Using the simplified slope-brushing system of this application, dam slope-brushing construction can be carried out after the dam body filling is completed, avoiding mutual interference between the synchronous construction of dam body filling and dam slope, and reducing construction efficiency.

[0030] Example 1:

[0031] See Figure 1 A simplified slope trimming system for earth-rock dams, the simplified slope trimming system for earth-rock dams comprising:

[0032] Slope brushing tool 1;

[0033] Two steel wire ropes 2 are respectively connected to both ends of the slope brushing tool 1;

[0034] Two pulleys 3 are arranged on the path of the wire rope 2 by the following mechanism 4, and the grooves of the pulleys 3 are in contact with the wire rope 2.

[0035] The traction mechanism 5 is connected to the end of the steel wire rope 2 away from the slope brushing tool 1. There are two traction mechanisms 5, which are located at the top and bottom of the earth-rock dam respectively.

[0036] Specifically, one end of one steel wire rope 2 is attached to the upper end of the slope-scraping tool 1, and the other end is attached to the tail end of a traction mechanism 5. One end of the other steel wire rope 2 is attached to the lower end of the slope-scraping tool 1, and the other end is attached to the tail end of another traction mechanism 5. Both steel wire ropes 2 are in contact with the grooves of pulleys 3. In this way, by moving the traction mechanism 5 back and forth and guiding the pulleys 3, the lengths of the steel wire ropes 2 at both ends of the slope-scraping tool 1 can be adjusted, thereby driving the slope-scraping tool 1 to move and complete the slope-scraping operation. Two following mechanisms 4 are provided, located at the top and bottom of the earth-rock dam respectively. Two pulleys 3 are fixed to the following mechanisms 4. The pulleys 3 support and guide the steel wire ropes 2 to keep the slope-scraping tool 1 balanced.

[0037] Furthermore, during the slope trimming construction, one traction mechanism 5 moves forward while another traction mechanism 5 moves backward, tightening the steel wire rope 2. Excess soil on the dam slope is removed using the slope trimming tool 1. After completing the slope trimming construction of one cross section, the traction mechanism 5 moves forward and the following mechanism 4 moves synchronously with the pulley 3. The above steps are repeated until the slope trimming construction is completed.

[0038] Since the length of the steel wire rope 2 in this application can be flexibly adjusted according to the dam height, when encountering a high earth-rock dam, only a longer steel wire rope 2 is needed in conjunction with the slope-scraping tool 1, pulley 3, following mechanism 4, and traction mechanism 5 to achieve slope-scraping operations, thereby ensuring that the construction progress is not affected. Using the simplified slope-scraping system of this application, dam slope-scraping construction can be carried out after the dam body filling is completed, so as to avoid the interference between the synchronous construction of dam body filling and dam slope and reduce construction efficiency.

[0039] Example 2:

[0040] See Figure 1 Based on Embodiment 1, optionally, the two pulleys 3 are located directly above and directly below the slope brushing tool 1, respectively.

[0041] Specifically, the two pulleys 3 are located directly above and below the slope brushing tool 1, respectively, to ensure that the slope brushing tool 1 does not tilt when it is pulled, so that it moves in a straight line up and down, thereby improving the aesthetics of the slope.

[0042] Optionally, the following mechanism 4 is an excavator, and the pulley 3 is mounted on the bucket of the excavator.

[0043] Specifically, by adjusting the excavator's boom and bucket, the pulley 3 can be adjusted in real time to guide the wire rope 2, thereby ensuring that the slope of the slope-scraping tool 1 meets the design requirements.

[0044] It should be noted that the number of pulleys 3 depends on the actual situation. In this embodiment, two pulleys 3 are sufficient to meet the requirements.

[0045] Optionally, the traction mechanism 5 is a loader.

[0046] Specifically, loaders are widely used in construction sites, are readily available, and provide sufficient traction. In addition to loaders, the towing mechanism 5 can also be an electric winch or a construction vehicle.

[0047] Optionally, the end of the wire rope 2 away from the slope-scraping tool 1 is fastened to the tail end of the loader.

[0048] Specifically, the loader is equipped with a high-strength tow hook or mooring point at the rear, and the wire rope 2 is fastened to the rear, making it less prone to slippage or breakage. The wire rope 2 is led out from the rear to avoid spatial interference with the front bucket and cab of the loader. The driver does not need to worry about the risk of the wire rope 2 getting tangled when operating, and can still clearly observe the connection status at the rear through the rearview mirror when working at night.

[0049] Optionally, the slope brushing tool 1 is a concrete block with a flat bottom and weight.

[0050] Specifically, using concrete blocks is simple and easy to manufacture, saving costs; the weight of the concrete blocks provides a certain anti-overturning moment, making them less likely to tip over on steep slopes due to fluctuations in the tension of the steel wire rope 2 or changes in soil resistance; the flat bottom of the concrete blocks ensures uniform cutting of the slope surface during the slope trimming process, avoiding local over-excavation or under-excavation, thus improving accuracy compared to traditional irregular slope trimming tools; the concrete blocks have good durability, resisting weathering and erosion in the earth-rock dam slope environment, resulting in a long service life. Additionally, it should be noted that there are no specific requirements for the shape of the slope trimming tool 1.

[0051] It should be noted that the structures and / or installation methods not detailed in this application are those that can be known by those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of this application, and will not be elaborated further here.

[0052] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
