These methods are difficult to apply inside culverts
If the subgrade and pavement are excavated and the waterproof structure is repaired, it will have a great impact on traffic operations
Due to the narrow interior space of reinforced concrete circular pipe culverts (most culverts have a diameter of 1.5m or less), the repair method of deformation joints of slab culverts and box culverts is very difficult to construct
The grouting repair method requires the use of hole-forming equipment, plugging and grouting and other processes are cumbersome and costly

Embodiment Construction
[0033] Such as figure 1 , figure 2 with image 3 The shown one is used for the repair of reinforced concrete circular pipe culverts, including the internal support connecting structure for connecting the first pipe section 1-1 and the second pipe section 1-2 on the circular pipe culvert 1 to be repaired. Ring-shaped steel belt 2, the two ends of the inner-supported annular steel belt 2 overlap each other, and the inner-supported annular steel belt 2 includes a first straight section 2-1 that is in contact with the first pipe section 1-1 , the second straight section 2-2 for contacting with the second pipe section 1-2 and the corrugated section 2-2 for connecting the first straight section 2-1 and the second straight section 2-2 3. The inner supporting ring-shaped steel belt 2 is installed with a device for expanding it so as to make the first straight section 2-1 and the first pipe section 1-1 closely fit and the second straight section 2-2 and The second pipe section 1-2 ...

The invention discloses an internally braced connecting structure for repairing a reinforced concrete circular pipe culvert, which includes an internally supported annular steel belt used to connect the first pipe joint and the second pipe joint on the circular pipe culvert to be repaired. The two ends of the inner braced annular steel belt are overlapped with each other, and the inner braced annular steel belt includes a first straight section that contacts and fits with the first pipe section, and a second straight section that is used for contacting and fitting with the second pipe section. section and a corrugated section used to connect the first straight section and the second straight section, and the inner supporting ring-shaped steel belt is installed with a corrugated section for expanding it so that the first straight section and the first pipe section Tight fitting and tight fitting of the second straight section and the second pipe section. The internal support connection structure can effectively connect the pipe joints on the circular pipe culvert to be repaired, and has a certain deformation ability, can effectively adapt to the deformation of the circular pipe culvert to be repaired, and can repair the leakage disease of the reinforced concrete circular pipe culvert pipe joint .
Description
technical field [0001] The invention belongs to the technical field of repairing reinforced concrete circular pipe culverts, and in particular relates to an inner support connection structure used for repairing reinforced concrete circular pipe culverts. Background technique [0002] Reinforced concrete circular pipe culvert is a culvert type commonly used in highway, railway and municipal engineering. With the increase of the service life of culverts, under the influence of factors such as load action and uneven deformation of the foundation, the pipe joints of some reinforced concrete circular pipe culverts have problems such as disengagement of pipe joints and misaligned teeth. After investigation, in some unfavorable geological regions, the maximum disengagement distance at the pipe joint joint has exceeded 200mm. If the diseases such as disengagement of pipe joints and wrong teeth are not repaired in time, it will lead to leakage and erosion damage of the culvert, whic...
