[0002] Grouting filling is a common technology in bridge maintenance, which is used for repairing defects and gaps in the internal structure of the bridge, and enhancing the stability and durability of the structure.

[0003] In a low temperature environment, this defect can cause the grouting material to easily condense, and when the grouting material condenses, its fluidity will be greatly reduced, which seriously affects the smooth progress of grouting. On the one hand, it may not be able to uniformly fill the grouting into the gap or cavity of the bridge, reducing the filling effect and affecting the repair quality of the bridge structure. On the other hand, the condensed material may also block the grouting pipeline, causing equipment failure, increasing maintenance cost and time cost of maintenance work. In order to ensure that the bridge maintenance grouting work can be completed efficiently and with high quality under various environmental conditions, it has become a top priority to develop a grouting storage container with good heat preservation performance and improve the existing bridge maintenance grouting filling equipment.

[0024] Please refer to Figures 1-4 In the embodiment, the inside of the tank body 101 is provided with the heat pipe 102; the front end of the tank body 101 is provided with the combustion furnace air blower 103, and the rear of the combustion furnace air blower 103 is provided with the gas combustion furnace 105, and the gas inlet end of the gas combustion furnace 105 is connected with the air supply end pipeline of the combustion furnace air blower 103; the combustion chamber pipeline of the gas combustion furnace 105 is located inside the heat pipe 102; the upper end of the tank body 101 is provided with the feeding sealing cover 107; the front of the feeding sealing cover 107 is provided with the smoke exhaust pipeline 104, and the smoke exhaust pipeline 104 is connected with the heat pipe 102 in the pipeline, and the smoke exhaust pipeline 104 and the combustion chamber pipeline built-in the gas combustion furnace 105 inside the heat pipe 102 are in communication; the rear end of the tank body 101 is provided with the grouting discharge valve 106, and the grouting discharge valve 106 is in communication with the inside of the tank body 101; the heat preservation support assembly 2 includes the water injection heat preservation box support 201 and the base 202; the lower end of the tank body 101 is provided with the water injection heat preservation box support 201 on both sides, and the inside of the water injection heat preservation box support 201 is injected with heat preservation water; the lower end of the water injection heat preservation box support 201 is provided with the base 202, and the base 202 is fixedly connected with the water injection heat preservation box support 201.

[0025] During operation, the gas combustion furnace 105 burns gas to heat the heat pipe 102. The combustion furnace blower 103 continuously blows oxygen into the gas combustion furnace 105 to aid combustion. At the same time, the airflow carries the hot gas along the heat pipe 102 to the exhaust pipe 104. The exhaust gas is discharged to the outside through the exhaust pipe 104. The heat pipe 102 improves the heat preservation function of the grouting material inside the tank 101, effectively reducing the problem of material condensation and clumping. This solves the problem of existing bridge maintenance devices, where the grouting storage container has low heat preservation performance, causing the grouting material to easily condense in a low-temperature environment.

[0026] Next, water is injected into the interior of the water-filled insulation box support 201. The high specific heat capacity of water is used to store the heat dissipated by the tank 101, thereby further improving the insulation performance of the tank 101 and reducing energy consumption.

[0027] Through the above steps, the gas combustion furnace 105 burns gas to heat the heat pipe 102. The combustion furnace blower 103 continuously blows oxygen into the gas combustion furnace 105 to assist combustion. At the same time, the airflow uses the hot gas to circulate along the heat pipe 102 to the exhaust pipe 104. The exhaust gas is discharged to the outside from the exhaust pipe 104. The heat pipe 102 improves the heat preservation function of the grouting material inside the tank 101, effectively reducing the problem of material condensation and clumping. This avoids the problem of existing bridge maintenance devices, where the grouting storage container has low heat preservation performance, causing the grouting material to easily condense in a low-temperature environment.
