The invention discloses a road bridge prefabricated small box girder type invisible cap beam temporary support system and a construction method thereof. The support system comprises a main beam, a main pier supporting system and a side pier supporting system, wherein the main beam is arranged along the transverse side of a road bridge pier; the main pier supporting system is arranged on the transverse side of a main pier area and located below the main beam, the lower end of the main pier supporting system is fixed with a main pier bearing platform, and the upper end of the main pier supporting system is fixed with the main beam; and the side pier supporting system is arranged on the transverse side of a side pier area and located below the main beam, and the lower end of the side pier supporting system is fixed with a side pier bearing platform, and the upper end of the side pier supporting system is fixed with the main beam. Therefore, the support system only has a large cross-diameter support beam (main beam) between the transverse main pier area and the side pier area, and other support systems arranged in the vertical direction are not present, so that a vehicle operation space is provided, and disassembly and assembly of the prefabricated small box girder type invisible cap beam support system are convenient. In addition, the support system has the characteristics of highbearing capacity so as to meet the supporting requirements of the prefabricated small box girder type invisible cap beam.

The invention relates to the field of ship construction and particularly relates to a detachable anti-falling device which comprises bases and a cover body, wherein the cover body is rotationally arranged on the bases through rotating shafts, each base is provided with a clamping device, and each clamping device comprises a body as well as a clamping part, a fixing part and a clamping hole which are arranged on the body, wherein the clamping part and the fixing part are arranged oppositely, an axial line of the clamping hole points to the fixing part, and the clamping part is movably penetrated in the clamping hole. The detachable anti-falling device provided by the invention is detachably connected to a lightening hole through the clamping devices arranged on the bases, and the cover bodyis rotationally arranged on the bases; and the detachable anti-falling device can be quickly mounted on the lightening hole through the clamping devices, the safety of construction workers can be guaranteed, and the construction workers can pass through the lightening hole conveniently.

The invention provides a cable guide mechanism which has the advantages that the structure is simple, adjustment is convenient and work reliability is improved. The cable guide mechanism comprises a rack; the guide mechanism comprises an upper base, a lower base, an upper guide wheel group and a lower guide wheel group; the upper base and the lower base are arranged on the rack respectively; the upper base is located above the lower base; the upper guide wheel group is movably arranged on the upper base; the lower guide wheel group is movably arranged on the lower base; the upper guide wheel group comprises a plurality of first guide wheels uniformly arranged side by side; the lower guide wheel group comprises a plurality of second guide wheels uniformly arranged side by side; and the first guide wheels and the second guide wheels are arranged in a staggered mode. The operation is convenient, and reliability is high.

The invention discloses a discrete type column type rail bridge system for the intra-garage overhaul of a maglev train. The rail bridge system comprises multiple rail bridge units of the same structure. The rail bridge units are arranged at intervals in the running direction of the maglev train and the interval distance s is larger than or equal to 0.5 m and smaller than or equal to 1.4 m. Each single rail bridge unit comprises a steel rail sleeper, two F-type steel rails and two supporting columns. The steel rail sleepers are horizontally arranged and are perpendicular to the running direction of the maglev train. Every two F-type steel rails are arranged at the two ends of the top of the corresponding steel rail sleeper. Every two supporting columns are arranged at the two ends of the bottom of the corresponding steel rail sleeper and provided with rail bearing tables connected with the bottom of the corresponding steel rail sleeper through fastener units. The height H of each supporting column is larger than or equal to 1.1 m and smaller than or equal to 1.3 m and the interval between every two adjacent supporting columns is larger than or equal to 0.5 m and smaller than or equal to 1.4 m. By the adoption of the discrete type column type rail bridge system, an overhaul person can penetrate the rail bridge system conveniently, and the problem that an existing rail is not suitable for the intra-garage overhaul of the maglev train is solved.

The patent of the invention discloses an urban road separating pedestrians from vehicles. All the components of the cross section of the urban road are not arranged on one horizontal plane, and are designed into concave or convex trapezoidal cross sections; green belts are designed into inclined planes meeting the head room of sidewalks to separating vehicles from pedestrians, so that motor vehicles driven on the bottom surfaces or (the top surfaces) and pedestrians walking on the top surfaces or (the bottom surfaces) have different ways and are not mutually interfered; pedestrian posterns or pedestrian footbridges are arranged at intersections, and pedestrian zebra crossings and pedestrian traffic lights are needless. The urban road separating pedestrians from vehicles avoids the phenomenon that the pedestrians and the vehicles are crowded in the same road, avoids traffic accidents of the pedestrians and the vehicles, provides convenience for the old, children, the disabled and other people in crossing the road, reduces damage to human beings caused by traffic pollution such as exhaust gas, noises, vibration and dust, and facilitates laying, repairing and maintaining various urban pipelines.
