Description

Technical Field

[0001] This invention relates to the field of integrated protection technology, specifically to a prefabricated integrated protection system for the top of a foundation pit slope and its construction process. Background Technology

[0002] Edge fencing is widely used on construction sites to separate vehicles, provide on-site safety protection, and achieve its separation function. It is used for safety protection of construction elevator shafts, passenger and freight elevator shafts, and foundation pit slopes, among other construction site edge protection measures, to achieve a barrier function. Its colors are typically yellow and black, red and white, or custom-made to match specific colors; its aesthetically pleasing design attracts attention and has a high visibility advantage, thus serving a warning function. Edge fencing is easy to install and remove, can be reused, and also significantly enhances the image of civilized construction in the city.

[0003] Currently, traditional construction methods are commonly used for foundation pit slope protection. This involves laying steel mesh on the slope of the foundation pit and using a pumped concrete spraying process to protect the slope. The same process is also used to connect the top surface layer with the slope surface layer to form a whole. This method is limited by the construction site, large machinery moves slowly, and on-site pumping and pouring of concrete followed by membrane curing is required, resulting in high labor and material costs and difficulty in controlling the forming quality. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated integrated protection system for the top of a foundation pit slope and its construction process, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated integrated protection system for foundation pit slope tops, comprising:

[0006] The base has a pit capping device fixed at its end;

[0007] A top support plate has a crossbar fixed to its end. The crossbar has a movable strip on its surface and a notch. An extension tube is provided at the top of the base, and a second insertion hole is provided at the top of the extension tube. A fixing rod is inserted into the second insertion hole.

[0008] The connecting rod is located at the top of the base.

[0009] Preferably, the base is provided in multiple sets, and the two sides of the base are provided with plug-in blocks and fixing holes. The shape of the plug-in blocks is consistent with the shape of the fixing holes. The plug-in blocks can be inserted into the fixing holes. There are two sets of connecting rods, and the connecting rods at the top of each set of bases can be connected together.

[0010] Preferably, a first insertion hole is provided at the top of the foundation pit capping, a C-shaped plate is inserted into the first insertion hole, one end of the C-shaped plate is inserted into the first insertion hole, a protective plate is fixed on the top of the C-shaped plate, the protective plate stands upright on the top of the foundation pit capping, and the other end of the C-shaped plate is stuck on the surface of the foundation pit capping.

[0011] Preferably, a top holding block is fixed to the surface of the fixing rod, and two sets of top holding blocks are provided, which are symmetrically distributed on the surface of the fixing rod. A screwing ring is sleeved on the surface of the fixing rod, which can move on the surface of the fixing rod. A limiting ring is provided at the bottom of the fixing rod, and the screwing ring is located at the top of the limiting ring.

[0012] Preferably, the inner diameter of the screw ring is the same as the outer diameter of the extension tube, the screw ring can be screwed onto the surface of the extension tube, the diameter of the fixing rod is the same as the diameter of the second insertion hole, and the fixing rod can be inserted into the second insertion hole.

[0013] Preferably, a telescopic rod is inserted into the surface of the base. The telescopic rod can move on the surface of the base, and the top of the telescopic rod is connected to a top holding plate and a crossbar. The two ends of the top holding plate are connected to the crossbar. The crossbar moves with the top holding plate, and the telescopic rod moves with the top holding plate and the crossbar.

[0014] Preferably, the top holding plate is located at the top of the C-shaped plate, and after the top holding plate is lowered, it holds the top of the C-shaped plate. The surface of the foundation pit capping is provided with stabilizing holes. The movable bar can move at the top of the crossbar. Both ends of the movable bar are arc-shaped, and one end of the movable bar is located in the notch.

[0015] Preferably, the position of the notch corresponds to the position of the top holding block, and the top holding block is held in the notch after it descends, and the top holding block is held at the end of the moving strip.

[0016] Preferably, the position of the stabilizing hole corresponds to the position of the moving bar. After the crossbar is lowered, the moving bar can move and be inserted into the stabilizing hole.

[0017] A construction process for a prefabricated integrated protection system for foundation pit slope tops includes the following steps:

[0018] Step 1: Assemble the base. Place the base at the location requiring protection. The base surface is equipped with connecting rods. The connecting rods between each group of bases can be connected together, allowing the bases to be linked. The plug-in blocks on the base surface can be inserted into the fixing holes, making the two groups of bases fit together tightly. Insert one end of the C-shaped plate at the bottom of the protective plate into the first plug-in hole. The other end of the C-shaped plate is clamped onto the surface of the pit capping to prevent the protective plate from tipping over. Insert the fixing rod into the second plug-in hole and screw the screw ring onto the surface of the extension tube, fixing the fixing rod to the surface of the two groups of bases, thus achieving the function of connection and fixation.

[0019] Step 2: Stabilization. During the descent of the fixed rod, the top support block holds the rod in the notch, causing the crossbar to descend. The top support plate holds the surface of the C-shaped plate, stabilizing the C-shaped plate. During the descent of the crossbar, the end of the top support block holds the end of the moving strip, causing the moving strip to move at the top of the crossbar. After the moving strip moves, the other end of the moving strip is inserted into the stabilizing hole, stabilizing the position of the crossbar and further stabilizing the protective plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The base proposed in this invention is placed at the location requiring protection. The surface of the base is equipped with connecting rods, allowing each group of bases to be connected. Insertion blocks on the base surface can be inserted into fixing holes, ensuring a tight fit between two groups of bases. One end of the C-shaped plate at the bottom of the protective plate is inserted into the first insertion hole, while the other end is secured to the surface of the pit capping to prevent the protective plate from tipping over. A fixing rod is inserted into the second insertion hole, and a screw ring is tightened to screw onto the surface of the extension tube, fixing the fixing rod to the surfaces of the two groups of bases for connection and fixation. During the descent of the fixing rod, a support block presses against the notch, causing the crossbar to descend. The support plate presses against the surface of the C-shaped plate, stabilizing it. During the descent of the crossbar, the end of the support block presses against the end of the moving strip, causing the moving strip to move at the top of the crossbar. After the moving strip moves, its other end is inserted into a stabilizing hole, stabilizing the position of the crossbar and further stabilizing the protective plate. Attached Figure Description
