[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.
[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0026] A device for avoiding secondary damage to embedded pipelines in narrow spaces, including a protective steel pipe 1. A plurality of pouring holes 3 are arranged on the upper part of the outer surface of the protective steel pipe 1, and four pouring holes 3 are arranged in a group at equal intervals longitudinally. Chutes 4 are arranged on both the front and rear sides of the inner surface of the protective steel pipe 1, and embedded pipe supports 2 are detachably installed on both the front and rear sides in the protective steel pipe 1 through the chutes 4.
[0027] In this embodiment, the embedded pipe support 2 includes a U-shaped support base 21. A support frame 22 is integrally formed at the lower end of the U-shaped support base 21, and the lower part of the support frame 22 is slidably connected to the chute 4; the U-shaped support base 21 is of a U-shaped structure, and a rubber pad 211 is fixedly connected to the inner surface of the U-shaped support base 21.
[0028] Through the above scheme: the support frame 22 is used to support the embedded pipe main body 5, which can lift the embedded pipe main body 5. At the same time, the design of the rubber pad 211 can protect the embedded pipe main body 5 and prevent wear caused by contact during construction, improving safety.
[0029] In this embodiment, avoidance grooves 23 are arranged on both the left and right sides of the upper end of the support frame 22, and two fixed screws 24 are inserted through the lower groove walls of the two avoidance grooves 23; the length of the chute 4 is greater than the length of the support frame 22, and four screw holes 41 for cooperating with the fixed screws 24 are arranged on the lower inner walls of the chute 4; the fixed screws 24 penetrate through the support frame 22 and are threadedly connected in the screw holes 41 to fixedly connect the lower part of the support frame 22 in the chute 4.
[0030] Through the above scheme: by passing the fixed screws 24 through the avoidance grooves 23 on the support frame 22 and connecting them to the screw holes 41 on the inner wall of the chute 4, the embedded pipe support 2 and the protective steel pipe 1 are designed to be detachable, which is convenient for later inspection and maintenance, and even replacement of damaged parts, reducing the maintenance cost.
[0031] It should be noted that the present utility model is a device for preventing secondary damage to pre-embedded pipelines in narrow spaces. The protective steel pipe 1 is provided with different pipe diameters, and the protective steel pipe 1 with different pipe diameters can be selected according to the pipe diameter of the pre-embedded pipe main body 5. During use, first, place the protective steel pipe 1 at the preset position to ensure that it is vertically aligned with the area of the pre-embedded pipeline to be protected. Then, slide the pre-embedded pipe support 2 into the protective steel pipe 1 through the chute 4. Utilize the sliding connection between the support frame 22 and the chute 4, and then pass the fixing screw 24 through the avoidance groove 23 on the support frame 22 and connect it to the screw hole 41 on the inner wall of the chute 4 to fix the position of the pre-embedded pipe support 2. Next, pass the pre-embedded pipe main body 5 through the protective steel pipe 1 and fix it in the U-shaped support seats 21 on the front and rear sides inside the protective steel pipe 1. Support the pre-embedded pipe main body 5 through the U-shaped support seats 21. Through the design of the rubber pad 211, the pre-embedded pipe main body 5 can be protected to prevent wear caused by contact during construction. Finally, pour concrete through the pouring holes 3 on the outer surface of the protective steel pipe 1. These pouring holes 3 ensure that the concrete can fully wrap the pre-embedded pipe main body 5. At the same time, the protective steel pipe 1 and the pre-embedded pipe support 2 inside it provide an additional protective layer. When it is necessary to install a bridge or a lamp on the roof, through the positioning of the protective steel pipe 1, the position of the pre-embedded pipe main body 5 can be accurately found, avoiding damage to the pre-embedded pipe main body 5 caused by direct drilling.
