Technical Field
[0001] This utility model relates to the field of concrete block technology, specifically to a snap-fit precast porous concrete block for use in subsidence areas. Background Technology
[0002] Precast concrete refers to concrete products made in a factory or on-site. Precast concrete is poured elsewhere rather than at the final construction site. Precast concrete of different sizes and shapes can be reinforced with fibers to enhance its reliability and toughness after cracking. With its low cost and excellent performance, precast concrete has become a new favorite in the construction industry. Ground subsidence is a common natural disaster that poses a serious threat to buildings, roads and other infrastructure. In order to address this challenge, the engineering community has been exploring effective reinforcement and repair methods to ensure that the infrastructure in these areas can operate stably and safely.
[0003] Existing precast porous concrete blocks lack reinforcing components in actual use and are prone to breakage, resulting in poor strength. Furthermore, the existing precast porous concrete blocks are not tightly joined together, and positioning during the joining process is quite troublesome. Utility Model Content
[0004] This utility model provides a snap-fit precast porous concrete block for use in subsidence areas. The base plate is fixed to the support screw by a limiting nut, and the connecting plate can be fixed to the support screw by rotating the nut. Then, the assembled reinforcement mechanism is placed in the mold, and then the concrete block is poured. After demolding, a porous concrete block is formed, which can reinforce the poured concrete block and increase its strength. Through the cooperation of the butt block and the butt groove, the porous concrete block can be installed according to the actual situation, which facilitates positioning and increases its tightness.

[0006] Furthermore, each set of docking mechanisms includes four docking blocks and four docking slots. The bottom of each docking block is fixedly connected to one side of the outer surface of the cast concrete block, and each docking slot is opened on one side of the outer surface of the cast concrete block. Each docking block and docking slot are matched with each other.
[0007] Furthermore, the support component includes four support screws and four support plates, each of which is fixedly sleeved on the outer surface of the support screw, and each of the support screws and support plates is located inside the cast concrete block.
[0008] Furthermore, the connecting component includes a base plate and four limiting nuts. The base plate is slidably sleeved on the outer surface of the four supporting screws, and each limiting nut is threadedly connected to the four supporting screws respectively.
[0009] Furthermore, each set of limiting components includes a connecting plate and two rotating nuts, each rotating nut being rotatably inserted through the bottom of the connecting plate, and each rotating nut being threaded onto the outer surface of the supporting screw.
