Abstract
Description
Technical Field
[0001] This utility model belongs to the field of slope protection technology, specifically a precast block structure for slope protection. Background Technology
[0002] The current situation is characterized by high water content on slopes in mountainous areas of southern China and the Qinling Mountains, as well as slopes near rivers and the sea, where annual rainfall is abundant. This is mainly reflected in the lithology of the slopes, which consists primarily of gravelly soil, completely weathered, and strongly weathered rock. Current engineering projects often employ methods such as strong support, drainage blind ditches, slope drainage holes, and large-area grid framework construction for slope management. The overall management approach is "drainage" and slope and toe protection. However, we often focus only on drainage while neglecting the inadequate protection and management of the slope. On the other hand, the use of strong support can prevent water from draining from the slope in a timely manner. Past engineering management often used on-site construction of retaining walls, anti-slide piles, drainage blind ditches, and grid frameworks, which are complex, time-consuming, costly, and difficult to control in terms of construction quality.
[0003] Meanwhile, a slope protection structure for ecological slope management, with announcement number CN209722871U, is disclosed. It includes a first base and a second base, with a slope between the first base and the second base. A soil collection pit is provided at the upper end of the second base. A water storage tank is buried in the slope. The water storage tank and the slope are connected by multiple water inlet pipes. A water pump is fixedly connected to the bottom of the water storage tank. A water outlet pipe is fixedly installed at the outlet end of the water pump. The upper end of the water outlet pipe passes through the first base and is connected to the slope. A separation mechanism is fixedly connected to the side wall of the water storage tank.
[0004] The aforementioned slope protection structure for ecological slope management can only be improved by adding a water storage tank for easier use, but it cannot reduce the complexity of construction, the long construction period, the high cost, or the difficulty in controlling the construction quality during use.

[0038] The working principle and process of a precast block structure for slope protection:
[0039] The design principle of this precast slope protection block structure is based on the cooperation of multiple precast units, aiming to achieve multiple functions such as slope stabilization, vegetation planting, and drainage, thereby effectively managing the slope. Longitudinal connection: the longitudinally protruding buckle 23 at the front edge of the slope masonry cap cooperates with the longitudinally recessed groove 26 at the rear edge of the slope masonry cap. This longitudinal buckle and groove design allows adjacent individual precast masonry units 2 to be tightly connected in the longitudinal direction, enhancing the structural stability in the vertical direction and preventing longitudinal displacement of the precast units under the gravity of the slope. The transversely protruding buckle 22 at the front edge of the slope masonry cap cooperates with the recessed groove 16 at the rear edge of the step masonry cap. The protruding buckle 12 at the front edge of the step masonry cap cooperates with the recessed groove 16 at the rear edge of the slope masonry cap. The horizontal recessed grooves 25 of the foot ensure a stable horizontal connection between the individual precast masonry unit 2 and the individual precast masonry unit 1 of the slope sloping steps, preventing the structure from sliding horizontally. The step masonry planting partition 13 provides an independent planting space for the slope sloping steps planting 3, separating the planting area from other structural parts, avoiding adverse effects of vegetation growth on structural stability, and also facilitating vegetation growth and maintenance. The step drainage channel 15 opened in the middle of the upper end face of the step masonry foot 14 can collect rainwater and other water flow from the slope and guide it to a suitable location for discharge, preventing water accumulation from eroding the slope and protecting the slope. To ensure the stability of the slope structure, place the precast individual masonry unit 1 for the slope sloping steps. Position the precast individual masonry unit 1 on the slope according to the design location, paying attention to the position and direction of the rear edge capping foot 14 of the step masonry to ensure it matches the slope's topography and design requirements. Install the precast individual masonry unit 2, placing it on the upper and lower end faces and left and right sides of the precast individual masonry unit 1. Specifically, first fix the front edge capping foot 21 of the slope masonry to the upper end face of the precast individual masonry unit 1. Then, align the longitudinal protruding buckle 23 of the front edge capping foot with the longitudinal recessed groove 26 of the rear edge capping foot and engage it. Simultaneously, align the transverse protruding buckle 23 of the front edge capping foot with the longitudinal protruding groove 26 of the rear edge capping foot. 2. Insert the recessed groove 16 of the rear edge capping foot of the step masonry, and insert the protruding buckle 12 of the front edge capping of the step masonry into the transverse recessed groove 25 of the rear edge capping foot of the slope masonry to complete the transverse and longitudinal connection. Lay geotextile 4 on the rear end face of the front edge capping 21 of the slope masonry, and then lay sand and gravel 5 on the left end face of the geotextile 4 and fix the sand and gravel 5 on the lower side of the rear edge capping foot 24 of the slope masonry. The laying of geotextile 4 and sand and gravel 5 can play the role of filtration and drainage, further enhancing the stability of the slope protection structure. On the inner side of the vegetation planting partition 13 of the step masonry, carry out the slope step vegetation planting 3. Select vegetation suitable for the local climate and slope environment for planting. During the planting process, pay attention to the spacing and maintenance of the vegetation so that it can grow well and play the role of vegetation slope protection.
