Problems solved by technology

[0008] Due to this construction method, the rigidity and self-weight of the full frame frame are used to ensure the stability and safety of the pump tube. Therefore, the two-way aspect ratio of the full frame frame must reach 1:1; that is, the height of the frame body is equal to The width of the bottom makes the whole frame very large and the installation period is long
[0009] 2. The performance of resisting dynamic load is poor, and the frame is easily deformed and unstable under the action...

Abstract

The utility model discloses an overhead attached type vertical steel pipe truss for assisting in mounting a pump pipe. The truss comprises truss steel pipe stand columns, truss cross rods, truss attachment rods and truss foundations. The number of the truss steel pipe stand columns is two. The two truss steel pipe stand columns are installed on the truss foundation at a certain interval, and the two sides of the opposite faces of the two truss steel pipe stand columns are connected by welding a plurality of truss transverse rods. A full-length truss internal space is formed between the multiple truss cross rods and the two truss steel pipe stand columns, and the truss internal space is used for pump pipe stand pipe installation and maintenance operation. The truss attachment rods are arranged on the upper portions of the truss steel pipe stand columns, located in the middles of the left width and the right width of the main bridge on the top of the truss and fixedly connected with thebridge structure body through embedded iron pieces. The truss is of an assembled structure and has the advantages of being small in size and good in bearing capacity, and therefore the stability of the pump pipe is improved.

Description

technical field [0001] The invention relates to the field of pump pipe fixing structures for concrete pumping and pouring on bridges, in particular to a volley-attached vertical steel pipe truss for auxiliary installation of pump pipes and a construction method thereof. Background technique [0002] When the concrete delivery pump is used to deliver concrete to the bridge deck of a high bridge (distance from the natural ground ≥ 20 meters), the pump pipe needs to be installed vertically from the ground to the concrete pouring work surface. During the construction process, it is necessary to meet the requirements of the stability, rigidity, maintainable working layer, reliability performance of high-altitude installation operations, and resistance to pump working loads. [0003] Existing technology is: adopt the construction technology of setting up floor-standing steel pipe fastener type full hall operating platform to assist in the installation of pump pipes. This technolo...
