The invention relates to a mechanical self-leveling express delivery transporting trolley. The mechanical self-leveling express delivery transporting trolley comprises goods, an anti-skid pad, a sensor, a pressure bearing foam plate, an upper side buffering external spring, an upper side buffering internal spring, a lower side buffering external spring, a lower side buffering internal spring, an article carrying plate, a supporting plate, an upper conical hole, a lower conical hole, a conical rubber pad, a heavy hammer, a fastening bolt, an adjusting nut, a supporting frame, a supporting baffle and a transporting vehicle; the upper conical hole and the lower conical hole are formed in the upper and lower ends of the middle part of the supporting plate; the conical rubber pad is arranged inthe upper conical hole; the heavy hammer is arranged in the conical hole; the bottom end of the heavy hammer is welded to the article carrying plate; a fence is arranged at the upper end of the article carrying plate; the article carrying plate supports the fence in which the goods are placed; the sensor is arranged at the lower end of the article carrying plate; and the sensor can measure the weight of the goods and can judge whether the goods are at the center of the article carrying plate. The mechanical self-leveling express delivery transporting trolley has the advantages that mechanicalautomatic leveling of the transporting trolley is realized by using gravity direction effect of the heavy hammer, and therefore, the mechanical self-leveling express delivery transporting trolley issimple and efficient.

The invention relates to a deep water silt layer geological large-span multi-line reinforcing system and a jacking culvert construction method, and aims at providing a reinforcing system and a construction method for a high-water-level, long-jacking-stroke, large-span and high-tonnage jacking culvert to penetrate through multiple existing lines. The reinforcing system comprises a high-pressure jet grouting secant pile, a fender pile, an anti-traversing pile and a supporting pile. The jacking culvert construction method comprises the steps of starry well-point dewatering, foundation pit excavation and sliding plate fabrication, frame bridge prefabrication, line reinforcement, jacking equipment installation and process control. By adopting starry well-point dewatering, the problems of underground water burst and foundation instability during jacking are solved; since a frame bridge is integrally jacked after being prefabricated, the rigidity is high, the seismic performance is good and the influence by climate is smaller; compared with the traditional construction method, the reinforcement and the installation are convenient and easy to operate, the jacking speed is quick and the construction period is shortened; I-shaped steel, steel rails and sleepers used for engineering can be recycled; the overall economic benefits are remarkable, the practical value is greater and the application prospect is wide.
