DETAILED DESCRIPTION

[0027] The following will be described in detail below in combination with the accompanying Figures 1-4 The present application will be further described in detail.

[0028] Please refer to Figures 1-3 A precise grouting plugging device for the connection between a manhole and a pipe well, comprising a steel body 1 and two pipeline mechanisms 2 mounted on the steel body 1, the steel body 1 is formed by a plurality of annular steels and a plurality of steel combinations, a tubular structure is formed by the plurality of steel combinations, and then the pipe well is formed by pouring concrete outside the steel body 1, the arrangement of the steel body 1 facilitates pouring of the pipe well, and at the same time, the arrangement of the steel body 1 facilitates installation of the pipeline mechanism 2, and the positions of the two pipeline mechanisms 2 after the pipe well is formed can be connected with other pipelines.

[0029] Refer to Figures 1-2The pipeline mechanism 2 for connecting auxiliary tube wells and other pipelines comprises a mounting pipe 3 clamped on the steel reinforcement body 1, and the inner wall of the mounting pipe 3 is clamped with a mounting column 4. The mounting pipe 3 is arranged to facilitate the connection of the pipeline of the tube well and the pipeline in the later period. The mounting column 4 blocks the mounting pipe 3 to prevent the mud from blocking the mounting pipe 3 during grouting. After pouring, the mounting column 4 can be directly removed. The arrangement of the mounting column 4 facilitates the effective avoidance of damage to the mounting pipe 3 caused by disassembly in the later period. The outer wall of the mounting pipe 3 is provided with two symmetrically arranged fixing assemblies 5. The fixing assemblies 5 directly fix the mounting pipe 3 on the steel reinforcement body 1, effectively ensuring the stability of the mounting pipe 3 on the steel reinforcement body 1. The outer wall of the mounting pipe 3 is provided with a grouting assembly 6. The arrangement of the grouting assembly 6 facilitates the accurate injection of mud. The arrangement of multiple grouting assemblies 6 facilitates the uniform injection of mud. An inspection well is installed for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage, communication, cable television, gas pipe, street lamp line and the like. Therefore, the inspection well needs to reserve the installation position of the pipeline during pouring, thereby facilitating the pipeline laying in the later period. The arrangement of the mounting pipe 3 facilitates the connection with the pipeline in the later period. However, the mounting pipe 3 is prone to moving during pouring of the tube well. Therefore, the fixing assembly 5 is arranged to fix the mounting pipe 3 on the steel reinforcement body 1, and the grouting assembly 6 is arranged to assist the grouting of the tube well.

[0030] In use, the steel reinforcement body 1 is arranged to facilitate the installation of the pipeline mechanism 2. The mounting pipe 3 in the pipeline mechanism 2 facilitates the installation of the pipeline in the later period. The mounting column 4 is arranged to support the mounting pipe 3 while effectively preventing mud from entering the inside of the mounting pipe 3 during grouting. The fixing assembly 5 is arranged to facilitate the fixation of the mounting pipe 3 on the steel reinforcement body 1. The grouting assembly 6 is arranged to facilitate the accurate grouting of the tube well.

[0031] Reference Figures 2-3The grouting assembly 6 comprises a mounting seat 7 fixedly connected to the mounting pipe 3, and a support column 8 fixedly connected to the outer wall of the top of the mounting seat 7.

A circular groove is formed in the outer wall of the top of the support column 8. A support frame 10 is fixedly connected to the inner wall of the circular groove. The support frame 10 supports the inner wall of the circular groove, so that the support column 8 is prevented from deforming. A plurality of arc-shaped openings 11 are formed in the inner wall of the circular groove at equal intervals. The arc-shaped openings 11 facilitate the discharge of the slurry in the circular groove. A plurality of wedge-shaped blocks 9 are fixedly connected to the outer wall of the support column 8 at equal intervals. A grouting pipe 12 is inserted into the outer wall of the support column 8. The wedge-shaped blocks 9 cooperate with the support column 8 to prevent the grouting pipe 12 from sliding downward and blocking the arc-shaped openings 11. Therefore, the slurry can be accurately injected into the convenient pipe well. The plurality of arc-shaped openings 11 formed in the inner wall of the circular groove facilitate the discharge of the slurry into the circular groove. The grouting pipe 12 facilitates the auxiliary conveying of the slurry. The plurality of wedge-shaped blocks 9 provided on the outer wall of the support column 8 facilitate the limitation of the downward movement of the grouting pipe 12. Therefore, the accurate grouting of the slurry is facilitated. The support frame 10 on the inner wall of the circular groove of the support column 8 facilitates the support of the support column 8. The mounting seat 7 facilitates the installation and fixation of the support column 8.

The outer wall of one side of the mounting ear one 13 is fixedly connected with a connecting bolt 14. The outer wall of one side of the mounting ear two 15 is provided with a circular opening. The mounting pipe 3 is installed on the steel body 1 through the two fixing assemblies 5. One end of the connecting bolt 14 penetrates through the circular opening, and the outer wall of the connecting bolt 14 is screwed with a locking nut 16. The mounting pipe 3 is fixed on the steel body 1 through the cooperation between the locking nut 16 and the connecting bolt 14, so that the movement of the mounting pipe 3 during grouting can be effectively avoided. The mounting pipe 3 is fixed on the steel body 1 through the cooperation between the locking nut 16 and the connecting bolt 14, so that the movement of the mounting pipe 3 during grouting is avoided.
