The invention discloses a transportation device of a coke oven fire-resistant material. The transportation device comprises a material lifting machine, a lower track, an upper track, a track trolley, a bearing platform and an all-round scaffold. According to the technical scheme, a transportation method of the coke oven fire-resistant material is particularly characterized by comprising the following steps: A, mounting and debugging the material lifting machine; B, erecting the all-round scaffold beside the machine; C, erecting the bearing platform; D, mounting the upper and lower tracks; E, transporting the fire-resistant material vertically and horizontally. By adopting the transportation device and the transportation method of the coke oven fire-resistant material, the coke oven fire-resistant material transportation and construction progress is effectively improved, the construction period of the fire-resistant material construction is shortened, full container load transportation of the fire-resistant material is achieved, the consumption amount of the fire-resistant material is reduced, the self-weight of a coke oven shed is reduced, and the construction cost is reduced.

The invention discloses a quick-transport device for foldable temporary cableways, which consists of an independent-rod temporary cableway bracket, a door-shaped temporary cableway bracket, a bearing cable, traction cables, a return sheave, a guide sheave, a traction driving grinding winch, a bearing cable anchoring pier, transporting running carts, chain blocks and a cargo shelf (15). A quick-transport method for the foldable temporary cableways includes: firstly, selecting temporary cableway transporting lines and erecting temporary cableways; secondly, setting the transporting running carts and the cargo shelf; and thirdly transporting equipment materials. By the quick-transport device and the quick-transport method which are convenient and reliable, difficulty in transporting of equipment and materials on steep mountains is reduced, the number of the temporary cableways is reduced, and transporting efficiency of the temporary cableways is improved.

The invention discloses a method for reducing the thickness of subsealing concrete of a steel cofferdam and preventing seepage, comprising the following steps of: a. assembling the steel cofferdam and welding an upper circle of shearing resistant structure and a lower circle of shearing resistant structure along the inner wall of the steel cofferdam; b. feeding the steel cofferdam in water; c. welding an upper circle of shearing resistant structure and a lower circle of shearing resistant structure on the outer wall of each steel protecting tube and sequentially punching the steel protecting tubes into a foundation in the steel cofferdam; d. constructing all drilling piles; e. cleaning the foundation in the steel cofferdam and flushing the steel cofferdam and the shearing resistant structures underwater on the steel protecting tubes; f. pouring the subsealing concrete to be combined with the steel protecting tubes, the steel cofferdam and the shearing resistant structure into a whole;and g. pumping water from the steel cofferdam and constructing a bearing platform. According to the method, by arranging the shearing resistant structures, after water in the steel cofferdam is pumped, the force transfer mode of the subsealing concrete and the inner wall of the steel cofferdam and the outer walls of the steel protecting tubes is converted into a bonding force and a shearing forcefrom the mutual bonding force, so that the dereference of the concrete bearing capacity accords with the reliable basis and the thickness of the subsealing concrete can be reduced; and the water seepagae in the steel cofferdam can be prevented.

The invention discloses a rainwater recycling system for sponge city overpass and a construction method of the rainwater recycling system. The rainwater recycling system comprises a rainwater collection device, rainwater pretreatment equipment and a water storage well, the rainwater collection device comprises a rainwater pipe and a collector, a water collection pump is mounted on the collector, and the rear end of the rainwater pipe is connected onto the water collection pump while the front end of the same is connected onto a deck of the overpass; the lower end of the collector is connected with a first guide pipe, the other end of the first guide pipe is connected with the rainwater pretreatment equipment, a diverter is mounted at the lower end of the rainwater pretreatment equipment, a second guide pipe is connected on the diverter and connected to the water storage well, a submerged pump is mounted in the water storage well, and a recycling pipe is connected on the submerged pump. An existing overpass draining pipeline is introduced into the collector, and rainwater is purified with the help of the rainwater pretreatment equipment, guided into the water storage well and then recycled through the recycling pipe, so that reasonable utilization of rainwater resources is realized, city water consumption pressure is relieved, the draining problem of the overpass is solved effectively, and city traffic is guaranteed.
