The complexity of pipeline layout has been continuously improved, resulting in a significant increase in the number of reserved holes. These reserved holes are mainly used for installing various pipelines, such as water supply and drainage pipes, ventilation pipes, etc. Especially in the reserved pipeline holes on the floor, a series of challenges are faced in the later plugging work. In the existing technology, the plugging of reserved holes on the floor is not only troublesome to operate, but also has a poor plugging effect. Content of the Utility Model

[0003] The purpose of this application is to provide a self-healing plugging structure for reserved holes on the floor to solve the problems of troublesome operation and poor plugging effect in plugging reserved holes in the existing technology.

[0004] To achieve this purpose, this application adopts the following technical solutions:

[0005] This application provides a self-healing plugging structure for reserved holes on the floor, which includes a through pipe penetrating through the reserved hole on the floor. A reinforcement layer is arranged between the reserved hole on the floor and the through pipe. The cross-section of the reinforcement layer is an inverted cone, and the reinforcement layer is configured to enhance the structural stability around the reserved hole;

[0006] A support ring is arranged below the reinforcement layer of the through pipe. The support ring is tightly connected to the through pipe. The support ring includes two arc rings, and the two arc rings are symmetrically arranged about the through pipe. The two arc rings are tightly connected by bolts. A semi-conical support platform is extended at the upper end of the arc ring, and the support platform is configured to cooperate with the through pipe to bear the weight of the reinforcement layer and avoid deformation of the overall structure.

[0007] Optionally, the reinforcement layer includes a first concrete layer, a waterproof layer, and a second concrete layer arranged in sequence from bottom to top.

[0008] Optionally, the waterproof layer includes a sodium bentonite layer and a polyester non-woven fabric isolation layer arranged in sequence from bottom to top; the thickness of the first concrete layer is 1 / 2 - 2 / 3 of the height of the reserved hole.

[0009] Optionally, connecting plates protrude outward from both end walls of the arc ring, and bolt holes are arranged in a position corresponding manner between the adjacent connecting plates on the two arc rings. The bolts pass through the bolt holes to fixedly connect the two arc rings.

[0010] Optionally, an anti-slip plastic layer is further connected to the inner side wall of the arc ring. The anti-slip plastic layer is configured to increase the friction between the arc ring and the through pipe, and the arc ring is made of PVC material.

[0011] Compared with the prior art, the present application has the following advantages:

[0012] The semi-conical support platform is connected and cooperated with the pipe body to bear the weight of the reinforcement layer, reduce the overall deformation. At the same time, such a structure can reliably transfer the weight of the concrete on the formwork to the pipe, and the anti-slip plastic layer makes the connection between the hole-casting formwork and the pipe more firm, realizing the firmness of the formwork;

[0013] In the present application, the arc ring is made of PVC material. Utilizing the characteristic that the adhesion of concrete to the plastic plate is poor, the convenience of demolition can be realized. At the same time, the surface of PVC is easy to be made into a mirror-like shape, which is convenient to set the support platform, thus ensuring good visual quality of the concrete after formwork removal;

[0014] In the present application, bentonite can form a paste-like liquid after swelling when the upper water seeps in, which can automatically fill the concrete cracks to achieve the self-healing property of waterproofing. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Please refer to Figures 1 to 4 As shown, a self-healing plugging structure for floor reserved holes provided by an embodiment of the present application includes a through pipe 2 penetrating through a floor reserved hole 4. A reinforcement layer 3 is provided between the floor reserved hole 4 and the through pipe 2. The cross-section of the reinforcement layer 3 is an inverted cone. The reinforcement layer 3 is configured to enhance the structural stability around the reserved hole 4.

[0022] The through pipe 2 is provided with a support ring below the reinforcement layer 3. The support ring is tightly connected to the through pipe 2. The support ring includes two arc rings 5. The two arc rings 5 are symmetrically arranged with respect to the through pipe 2. The two arc rings 5 are fixedly connected by bolts. The upper end of the arc ring 5 extends with a semi-conical support platform 6. The support platform 6 is configured to cooperate with the through pipe 2 to bear the weight of the reinforcement layer 3 and avoid deformation of the overall structure.

[0023] In one embodiment, the reinforcement layer 3 includes a first concrete layer 8, a waterproof layer 9, and a second concrete layer 10 arranged in sequence from bottom to top.

[0024] In one embodiment, the waterproof layer 9 includes a sodium bentonite layer 11 and a polyester non-woven fabric isolation layer 12 arranged in sequence from bottom to top. The thickness of the first concrete layer 8 is 1 / 2 to 2 / 3 of the height of the reserved hole 4.

[0025] In one embodiment, both end walls of the arc ring 5 protrude outwards with connecting plates 13. Bolt holes 7 are provided at corresponding positions between the adjacent connecting plates 13 on the two arc rings 5. Bolts pass through the bolt holes 7 to fixedly connect the two arc rings 5.

[0026] In one embodiment, an anti-slip plastic layer 14 is further connected to the inner side wall of the arc ring 5. The anti-slip plastic layer 14 is configured to increase the friction between the arc ring 5 and the through pipe 2. The arc ring 5 is made of PVC material.

[0027] When the present utility model is specifically implemented:

[0028] Clean the reserved hole 4, remove sundries such as wood chips, templates, and sleeves attached to the concrete at the hole, chisel off the loose concrete at the hole, and then roughen the side concrete of the hole. Use a chisel to make the smooth side surface into an uneven rough surface. When roughening, make the reserved hole 4 into an inverted cone shape, wider at the top and narrower at the bottom. The upper diameter is 4 - 6 cm larger than the pipe, and the lower diameter is 2 - 3 cm larger than the pipe.

[0029] The arc ring 5 consists of two semi-circular templates. During installation, use bolts to tightly hold the pipe, so that the two semi-circular templates form an integral body with the pipe. The rubber makes the connection between the template and the pipe more firm, realizing the firmness of the template. By adjusting the tightness of the bolts, the installation and removal of the template can be achieved. The support platform 6 cooperates with the arc ring 5 to increase the strength of the arc ring 5 and reduce the overall deformation.

[0030] The support platform 6 abuts against the bottom wall of the floor slab 1. Before the plugging and pouring, fully water the reserved hole 4 to moisten it. Use micro-expansion concrete (the expansion agent addition ratio is expansion agent: cement = 1:10) to construct the first concrete layer 8, and the laying height is 1 / 2 - 2 / 3 of the thickness of the floor slab 1. After the first concrete layer 8 coagulates, successively lay a 5 - mm - thick sodium - bentonite waterproof layer 9, and then cover it with a 100 - g / ㎡ polyester non - woven fabric isolation layer 12.

[0031] Continue to lay the second concrete layer 10 until it is flush with the floor slab 1, and appropriately slope outward from the pipe edge along the perimeter of the pipe. Finally, smooth the surface.

[0032] After the concrete coagulates and reaches the strength, the support ring can be removed.
