Description

Technical Field

[0001] This utility model relates to the field of protective barrier technology, specifically to a novel reinforced concrete protective barrier. Background Technology

[0002] For factories that produce or store industrial explosives, protective earthen dikes are typically erected around the premises to reduce the destructive effects of air shock waves and flying debris on surrounding buildings and personnel during an explosion. Earthen dikes occupy a large area and require a significant amount of soil, and higher dikes can complicate construction. Given my country's large population and limited land resources, and the increasing scarcity of land, reinforced concrete barriers are often used instead of earthen dikes when conditions permit, in order to conserve land.

[0003] Traditional single-layer protective barriers consist of a raft foundation and a wall standing on the raft foundation. Typically, the bottom portion of both the raft foundation and the wall is buried in the soil. The area of ​​the raft foundation for a single-layer protective barrier is determined by the self-weight of the wall and wind loads, neglecting the overturning effect of the bending moment generated by the blast load on the raft foundation. This results in a weak overturning resistance of the protective barrier. Furthermore, single-layer protective barriers have low out-of-plane stiffness, making them less resistant to out-of-plane shock wave loads. Utility Model Content

[0004] (I) The problem to be solved by this utility model is that traditional single-layer protective barriers have weak overturning resistance, low out-of-plane stiffness, and weak resistance to out-of-plane shock wave loads.

[0006] A novel reinforced concrete protective barrier includes a raft foundation, walls, cast-in-place piles, and buttresses;

[0007] The wall is vertically installed on the surface of the raft foundation and is cast integrally with the raft foundation. At least two cast-in-place piles are provided. The cast-in-place piles are installed below the raft foundation along a first direction and are connected to the raft foundation.

[0008] The buttress is located above the raft foundation and on one side of the back surface of the wall. The buttress has a horizontal bottom surface and a vertical side surface.

[0009] According to one embodiment of the present invention, the novel reinforced concrete protective barrier includes a top beam and a cross beam, the top beam and the cross beam being arranged sequentially along a first direction, the first direction being the arrangement direction of the wall and the cast-in-place piles, the top beam and the cross beam being located on the back surface of the wall, and the top beam being higher than the cross beam, the top beam and the cross beam being respectively connected to the buttress.

[0010] According to one embodiment of the present invention, multiple buttresses are provided, and the multiple buttresses are evenly arranged along a second direction, which is perpendicular to the first direction.

[0011] According to one embodiment of the present invention, the buttress is in the shape of a right-angled triangular plate, the buttress has an inclined surface, and the inclined surface is connected to the horizontal bottom surface and the vertical side surface respectively.

[0012] According to one embodiment of the present invention, a plurality of cast-in-place piles are provided, and the plurality of cast-in-place piles are evenly arranged along a second direction.

[0013] According to one embodiment of the present invention, the cast-in-place piles correspond one-to-one with the buttresses, the cast-in-place piles are located directly below the wall, and the projection of the vertical side of the buttress toward the raft foundation falls onto the corresponding cast-in-place pile.

[0015] According to one embodiment of the present invention, along the first direction, the cast-in-place pile becomes narrower, and the diameter of the cast-in-place pile at one end near the raft foundation is smaller than the diameter of its other end.

[0016] According to one embodiment of the present invention, the cast-in-place pile includes exposed reinforcing bars, which extend into the interior of the raft foundation and are cast integrally with the raft foundation.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a novel reinforced concrete protective barrier, comprising a raft foundation, a wall, cast-in-place piles, and a buttress; the wall is vertically installed on the upper surface of the raft foundation and is cast integrally with the raft foundation; at least two cast-in-place piles are provided, which are installed below the raft foundation along a first direction and connected to the raft foundation; the buttress is installed above the raft foundation and located on one side of the back surface of the wall; the buttress has a horizontal bottom surface and a vertical side surface, the horizontal bottom surface of which is connected to the upper surface of the raft foundation, and the vertical side surface of which is connected to the back surface of the wall.

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figures 1-5As shown, one embodiment of this utility model provides a novel reinforced concrete protective barrier, including a raft foundation 1, a wall 3, cast-in-place piles 2, and a buttress 6; the wall 3 is vertically installed on the upper surface of the raft foundation 1 and is cast integrally with the raft foundation 1; at least two cast-in-place piles 2 are provided, and the cast-in-place piles 2 are arranged along a first direction below the raft foundation 1 and connected to the raft foundation 1.

[0029] The buttress 6 is located above the raft foundation 1 and on one side of the back surface 302 of the wall 3. The buttress 6 has a horizontal bottom surface and a vertical side surface. Its horizontal bottom surface is connected to the upper surface of the raft foundation 1, and its vertical side surface is connected to the back surface 302 of the wall 3. The first direction is the vertical direction.

[0030] In this embodiment, cast-in-place piles 2 and buttresses 6 are added to the traditional reinforced concrete protective barrier. Specifically, cast-in-place piles 2 are driven into the ground, and the reinforcing bars of the raft foundation 1 are tied to the cast-in-place piles 2. The reinforcing bars of the wall 3 and buttresses 6 are then tied, and finally the casting formwork is erected and concrete is poured.

[0031] Because the cast-in-place piles 2 are cast as a single unit with the raft foundation 1, and because the piles 2 are deeply embedded in the ground, the overturning resistance of the raft foundation 1 is significantly improved, which in turn enhances the anti-slip and anti-overturning properties of the reinforced concrete protective barrier under explosive loads. Furthermore, the buttresses 6 support the wall 3 and are connected to both the raft foundation 1 and the wall 3, thereby strengthening the connection between them and increasing the overall strength of the reinforced concrete protective barrier. This results in improved out-of-plane stiffness and enhanced resistance to out-of-plane shock wave loads.

[0032] Figure 2 This is a front view of a reinforced concrete protective barrier. Figure 3 This is a side view of a reinforced concrete protective barrier, such as... Figure 2 and Figure 3 As shown, the wall 3 has a parallel blast-facing surface 301 and a blast-avoiding surface 302. A buttress 6 is located on one side of the blast-avoiding surface 302, and its bottom surface is connected to the upper surface of the raft foundation 1. Its vertical side facing the wall 3 is also connected to the wall 3. The buttress 6 supports the wall 3 from the blast-avoiding surface 302 and is also connected to the raft foundation 1, thereby strengthening the connection between the wall 3 and the raft foundation 1 and improving the overall strength of the reinforced concrete protective barrier. When the blast shock wave acts on the wall 3, because the buttress 6 supports the wall 3 from the blast-avoiding surface 302, the buttress 6 strengthens the overall strength, thereby improving the out-of-plane stiffness of the reinforced concrete protective barrier and enhancing its resistance to shock wave loads.

[0033] As a preferred embodiment, such as Figure 2As shown, the raft foundation 1 has parallel left and right sides, and the left and right sides of the raft foundation 1 are parallel to the back surface 302 of the wall 3. The ratio of the distance between the wall 3 and the left side of the raft foundation 1 to the distance between the wall 3 and the right side of the raft foundation 1 is 1 / 5 to 2 / 5, preferably 2 / 5. That is, the wall 3 is closer to the left side of the raft foundation 1, so that the center of gravity of the wall 3 and the raft foundation 1 as a whole is closer to the left side of the raft foundation 1. Further, as... Figure 3 As shown, the distance between the axis of the cast-in-place pile 2 and the left side of the raft foundation 1 is b, and the distance between the axis of the cast-in-place pile 2 and the right side of the raft foundation 1 is a. The ratio of b to a ranges from 1 / 5 to 2 / 5, preferably 2 / 5. It is important to emphasize that under the action of a shock wave, the reinforced concrete protective barrier will experience horizontal displacement and overturning. Since the horizontal shear force and displacement of the raft foundation 1 at the bottom of the barrier are relatively large, to prevent the barrier from sliding and overturning, the cast-in-place pile 2 is moved closer to the left side of the raft foundation 1, making the anti-overturning moment greater than the overturning moment, i.e., making a greater than b. This improves the anti-slip and anti-overturning properties of the reinforced concrete protective barrier under explosive loads.

[0034] To further improve the out-of-plane stiffness and resistance to out-of-plane shock wave loads of reinforced concrete protective barriers, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a top beam 4 and a cross beam 5 are installed on the back surface 302 of the wall 3. The top beam 4 is higher than the cross beam 5 and parallel to the cross beam 5. The buttress 6 is connected to both the top beam 4 and the cross beam 5. It should be noted that the buttress 6 is in the shape of a right-angled triangle. The buttress 6 has a horizontal bottom surface, a vertical side surface, and an inclined surface. The internal steel bars of the top beam 4 are tied to the steel bars of the wall 3 to form a whole. The internal steel bars of the cross beam 5 are tied to the steel bars of the wall 3 to form a whole. The vertical steel bars of the buttress 6 are tied to the steel structure of the raft foundation 1. The horizontal steel bars of the buttress 6 are tied to the steel structure of the wall 3 and the steel bars of the cross beam 5. The buttress 6 also has inclined steel bars. One end of the inclined steel bar is tied to the steel bars of the top beam 4, and its bottom end is tied to the steel structure of the raft foundation 1.

[0035] In this way, the raft foundation 1, top beam 4, cross beam 5 and buttress 6 are integrated, and the overall strength is improved. The buttress 6 is also connected to the wall 3, top beam 4, cross beam 5 and raft foundation 1. The buttress 6 can better support the wall 3, thereby improving the overall strength of the reinforced concrete protective barrier, and improving the out-of-plane stiffness and resistance to out-of-plane shock wave loads of the reinforced concrete protective barrier.

[0036] It should be noted that the triangular buttress 6 has good stability, which can more stably support the wall 3 and better strengthen the connection between the wall 3 and the raft foundation 1, thereby improving the ability of the reinforced concrete protective barrier to resist out-of-plane shock wave loads.

[0037] In this embodiment, specifically, such as Figure 1 and Figure 2 As shown, multiple buttresses 6 and multiple cast-in-place piles 2 are provided. The number of buttresses 6 and cast-in-place piles 2 is the same and corresponds one-to-one. The buttresses 6 are evenly distributed along the second direction, which is the length direction of the raft foundation 1. Multiple cast-in-place piles 2 are arranged in a row along the length direction of the raft foundation 1, with a corresponding cast-in-place pile 2 provided below each buttress 6. It should be noted that, combined with Figure 4 and Figure 5 As can be seen, the downward projection of the vertical side of the buttress 6 falls onto the top surface of the cast-in-place pile 2. It should be noted that there is no specific limit to the number of buttresses 6 and cast-in-place piles 2.

[0038] As an optional embodiment, in order to improve the pull-out resistance of the cast-in-place pile 2, the bottom of the cast-in-place pile 2 is thickened, that is, the diameter of the bottom of the cast-in-place pile 2 is greater than the diameter of its top. This cast-in-place pile 2 is more stable after being driven into the ground, thereby improving the overturning resistance of the reinforced concrete protective barrier.
