Description

Technical Field

[0001] The utility model relates to the technical field of highway construction protection, in particular to an edge protection device for pile foundation steel casing construction. Background Art

[0002] In the process of manual bored pile construction, due to the instability of the soil, it is very difficult to construct reinforced concrete retaining walls. Steel retaining walls, i.e. steel casings, are often used to protect the bored piles to prevent the hole from collapsing, thereby avoiding affecting the construction progress and safety.

[0003] Steel casing is a circular barrel with both ends hollowed out by iron hoops according to the size of the pile hole. At present, when constructing the pile foundation on water in highway projects, it is necessary to cut a square opening at the steel trestle panel and drive the steel casing into the water. However, this method has a weaker protective function. When in use, because the steel casing is circular like the pile foundation, but the panel cutout is square, there are holes in the four corners, which may cause people to fall or objects to fall, and the personal safety of construction workers cannot be effectively protected, resulting in certain safety hazards during construction. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pile foundation steel casing construction edge protection device which can improve the safety.

[0005] In order to solve the above problems, the utility model discloses a pile foundation steel casing construction edge protection device, which is characterized in that: the protection device is composed of 4 tightly fitted protection units; each protection unit includes an arc rod and an L-shaped fixing frame connected together by a connecting rod; the top center of the arc rod is fixedly connected to a support rod, and the side top of the support rod is fixedly connected to an extension rod; the ends of the extension rod are fixed to two ends on the fixing frame; the back top of the support rod is fixedly connected to a positioning rod, and the end of the positioning rod is fixed at the vertex of the fixing frame; the top of the connecting rod is fixedly connected to an auxiliary rod, and the end of the auxiliary rod is fixed to the bottom center of the extension rod; a protection net is fixedly connected in the plane formed by the fixing frame, the extension rod and the positioning rod.

[0006] The two ends of the back side of the arc-shaped rod are respectively connected to the two ends of the fixing frame through the connecting rods.

[0007] The inner wall of the arc-shaped rod is embedded with a steel casing.

[0008] The back side of the fixing frame is fixedly connected with a fixing seat, and the top of the fixing seat is threadedly connected with a fixing bolt.

[0009] A fixing rod is fixedly connected to the center of the back side of the arc-shaped rod, and one end of the fixing rod is fixedly connected to the center of the inner wall of the fixing frame.

[0010] The back side of the arc-shaped rod is fixedly connected with reinforcing rods on both sides close to the fixing rod; one end of the reinforcing rod is fixedly connected to the inner wall of the fixing frame and is parallel to the fixing rod.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The utility model is composed of 4 protective monomers that fit closely together. Each protective monomer includes an arc rod connected together by a connecting rod and an L-shaped fixing frame. The inner wall of the arc rod is embedded with a steel casing, so that the steel casing is surrounded by four protective monomers of the same size in the middle, which can effectively prevent construction workers from stepping on the gaps cut around the steel casing.

[0013] 2. In the utility model, a protective net is arranged in the plane formed by the fixing frame, the extension rod and the positioning rod, which can prevent construction workers from accidentally stepping on air and falling in unexpected situations, thereby improving safety during construction.

[0014] 3. In the utility model, by providing a protective unit mainly composed of an arc rod, a connecting rod, a fixing frame, a supporting rod, an extension rod, a positioning rod and an auxiliary rod, the overall firmness and stability of the protective device are ensured.

[0022] like Figures 1 to 4As shown, a device for protecting the edge of a pile foundation steel casing is composed of four tightly fitted protective units; each protective unit includes an arc rod 1 and an L-shaped fixing frame 3 connected together by a connecting rod 2; a support rod 4 is fixedly connected to the top center of the arc rod 1, and an extension rod 5 is fixedly connected to the top of the side of the support rod 4; the ends of the extension rod 5 are fixed to the two ends on the fixing frame 3 to improve the stability of the support rod 4; a positioning rod 6 is fixedly connected to the top of the back of the support rod 4, and the end of the positioning rod 6 is fixed to the top of the fixing frame 3, and the stability of the support rod 4 is improved by the positioning rod 6 and the extension rod 5. An auxiliary rod 7 is fixedly connected to the top of the connecting rod 2, and the end of the auxiliary rod 7 is fixed to the bottom center of the extension rod 5; a protective net 8 is fixedly connected in the plane formed by the fixing frame 3, the extension rod 5, and the positioning rod 6.

[0023] Wherein: the two ends of the back side of the arc rod 1 are connected to the two ends of the fixing frame 3 through the connecting rod 2 respectively.

[0024] A steel casing 9 is embedded in the inner wall of the arc-shaped rod 1 .

[0025] A fixing seat 10 is fixedly connected to the back of the fixing frame 3 , and a fixing bolt 11 is threadedly connected to the top of the fixing seat 10 .

[0026] A fixing rod 12 is fixedly connected to the back center of the arc rod 1, and one end of the fixing rod 12 is fixedly connected to the inner wall center of the fixing frame 3, thereby improving the stability and firmness between the fixing frame 3 and the arc rod 1, and ensuring the overall safety effect and durability of the device.

[0027] The back of the arc rod 1 is fixedly connected to both sides of the fixing rod 12 with a reinforcing rod 13; one end of the reinforcing rod 13 is fixedly connected to the inner wall of the fixing frame 3 and is parallel to the fixing rod 12. When in use, the reinforcing rod 13 can improve the connection between the arc rod 1 and the fixing frame 3 to prevent deformation, improve the stability between the arc rod 1 and the fixing frame 3, ensure the stable use of the device, and prevent the device from being degraded in functionality after long-term use.

[0028] When in use, the staff needs to design a protective unit composed of an arc rod 1, a connecting rod 2, a fixing frame 3, a supporting rod 4, an extension rod 5, a positioning rod 6 and an auxiliary rod 7 according to the size of the steel casing 9, so as to ensure the overall firmness and stability of the protective device. Adding a protective net 8 to the gap between the main rods can prevent the construction workers from accidentally stepping on air and falling in unexpected situations, thereby improving the safety during construction.

[0029] By surrounding the steel casing 9 with four protective units of the same size, construction workers can be effectively prevented from stepping on the gaps cut around the steel casing. At the same time, after determining the position of each protective unit, the fixing bolt 11 is rotated into the fixing seat 10 on the back of the fixing frame 3, so that each protective unit is fixed on the ground, thereby improving the stability of the entire protective device and avoiding displacement during use.
