Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building construction gantry device. Background Art

[0002] With the development of the times, my country's highways and railways are developing in the direction of high speed and heavy load, which leads to the continuous increase of foundation bearing capacity. Therefore, large pile group foundations are widely used in bridge projects in soft soil areas, and super-long and large-diameter pile groups are the most common ones. However, in actual projects, the spacing of pile foundations is limited by the structural form, resulting in a narrow construction surface. The site needs to be placed with mechanical equipment such as rotary drilling rigs, rotary drilling rigs, truck cranes, crawler cranes, mud filter boxes, excavators, etc., which makes the construction surface problem of pile foundations more prominent.

[0003] In the field of bridge construction, the construction process of bored piles mainly includes burying casing, drilling, cleaning holes, hoisting steel cages, pouring concrete, etc.

[0004] In the existing construction plan, the mechanical equipment involved in the construction process, such as truck cranes, crawler cranes, etc., will be occupied for a long time, and it is difficult to be used for the scheduling of other pile foundations. For example, crawler cranes are used to lower / pull out the conduits, and truck cranes are used to transfer the conduits, and the conduits require additional cleaning processes, which makes it difficult to improve construction efficiency and slows down the construction progress. Therefore, it is necessary to replace large-scale mechanical equipment to lift tubular parts such as conduits, and clean the parts while lifting and pulling them out, so as to save processes and improve overall construction efficiency.
