This invention relates to the field of grounding angle steel construction technology and provides a construction device for grounding angle steel of roadbed contact network foundation. The device includes a telescopic base frame, with main trusses fixedly connected to the four corners of the upper surface of the telescopic base frame. Folding ground anchors are symmetrically hinged to both sides of the telescopic base frame. A telescopic top frame is fixedly connected to the top of the main truss. A horizontal positioning device is fixedly installed on all four sides of the telescopic top frame. Folding handles are symmetrically hinged to both sides of the telescopic top frame. A protective net is installed at the bottom of the telescopic top frame. Guide components are installed inside both the telescopic base frame and the telescopic top frame. This construction device for grounding angle steel of roadbed contact network foundation can automatically drive the grounding angle steel by striking it with a hammer and buffer pad as the hollow tube moves downwards. This reduces the problem of unsatisfactory angle and depth when manually driving the grounding angle steel, improves the construction efficiency, and ensures the quality after construction.

The utility model provides a movable hoisting platform for a shield working well, the movable hoisting platform comprises a movable platform and two walking tracks, the two walking tracks are symmetrically laid on a ring beam of the shield working well, and each walking track horizontally extends from the ring beam to a middle plate adjacent to the ring beam; the moving platform is a square platform, electric walking wheels are arranged on the front side of the moving platform, two sets of driven rolling wheels are arranged at the tail end of the moving platform, the two sets of driven rolling wheels of the moving platform are correspondingly arranged on the two rails and horizontally move on the rails, and the electric walking wheels move on the middle plate; the other three edges of the movable platform except one edge adjacent to the middle plate are all provided with protective fences, and a lifting frame is arranged in the middle of the movable platform. The safety risk of hoisting and transferring materials is reduced, the construction efficiency is improved, the problem of space limitation of hoisting a wellhead is solved, the space utilization rate and the hoisting efficiency of hoisting the wellhead are improved, and the number of auxiliary hoisting personnel is reduced.

The utility model discloses a novel combined steel formwork for a fan foundation, and relates to the field of fan foundation construction. Comprising a first template and a second template, butt joint supporting feet are fixedly installed at the two ends of the first template and the two ends of the second template, installation screw holes are formed in the butt joint supporting feet, butt joint holes are formed in the first template, a connecting mechanism is arranged on the second template, and a positioning base is fixedly installed on the second template. A positioning through hole is formed in the edge of the positioning base, a positioning column is fixedly installed in the middle of the positioning base, a limiting pressing piece is arranged on the positioning column, a limiting nut is installed on the positioning column, and supporting mechanisms are arranged on the side wall of the first template and the side wall of the second template. According to the formwork, original single-block splicing is changed into bottom quarter circle splicing, the splicing number and workload are reduced, the construction efficiency is improved, meanwhile, the adjusting supporting columns can be inserted into the ground after stretching out, and therefore the periphery of the formwork body can be rapidly supported.
