The invention discloses a pile-breaking-free mechanical connection method between a reinforced concrete square pile and a bearing platform, and the connection method comprises the following steps: manufacturing a steel reinforcement framework, connecting the steel reinforcement framework with a pile top end plate through a steel sleeve, and then pouring a concrete pile body to form the reinforced concrete square pile; the reinforced concrete square pile is subjected to pile sinking construction; and the pile top end plate is dismantled, and the bearing platform anchoring rib and the reinforced concrete square pile are mechanically connected through the steel sleeve. According to the pile-breaking-free mechanical connection method between the reinforced concrete square pile and the bearing platform, mechanical connection between the reinforced concrete square pile and the bearing platform can be achieved without mechanical breaking of the pile head of the reinforced concrete square pile, field welding work is avoided, construction is convenient and fast, and the method is more economical and reasonable.

The utility model relates to the technical field of municipal water supply and drainage pipeline, especially to a sewage intercepting trench in a culvert. The sewage intercepting trench in the culvert comprises: brick-laid side walls arranged at intervals along the leakage section of the existing retaining wall, river channel side walls arranged opposite to the brick-laid side walls, and prefabricated cover plates arranged on the top of the brick-laid side walls and the river channel side walls, a water outlet is formed between adjacent brick-laid side walls, and the river channel side walls are provided with waterproof structures. The sewage intercepting trench in the culvert provided by the utility model can alleviate the problem that sewage leakage from the retaining wall in the culvert is serious and it is difficult to trace the source and rectify.
