Heavy-duty carrying equipment and construction method thereof

Abstract

The invention provides heavy-duty carrying equipment and a construction method. A framework attachment structure comprises a lower force-bearing pile frame structure and a top support structure; the top support structure is detachably and circumferentially connected onto the lower force-bearing pile frame structure; an overall downward-moving device is arranged between the top support structure and a heavy-duty soil lifting device; the heavy-duty soil lifting device comprises a peripheral framework structure, a car system, a main body lifting system and an electric control system; the peripheral framework structure comprises a bottom supporting beam frame and standard knots detachably connected onto the bottom supporting beam frame; the standard knots are stacked and connected according tothe depth of a support project; support force-bearing structures on the outer sides of the standard knots are matched with downward-moving mechanisms; and through rising and falling of a lifting device and carrying of a bearing shaft and the support force-bearing structures, overall downward movement of the heavy-duty soil lifting device is realized. According to the heavy-duty carrying equipmentand the construction method, the equipment can be used repeatedly in different foundation pit projects in a circulating manner, so that the economic efficiency and the environment-friendliness of soil lifting equipment are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of deep foundation pits, and in particular relates to heavy-duty carrying equipment and a construction method thereof. Background technique [0002] With the increasing speed of urban construction, high-rise and super high-rise buildings have become the main architectural forms of many central cities, and a large number of subway station buildings, high-rise and super high-rise structures have also appeared. As it gets deeper and deeper, considering the safety factor, the application of inner braces in deep foundation pits is becoming more and more common. When ensuring the safety of foundation pits, the excavation efficiency of deep foundation pits will be affected by the narrowness of the inner and surrounding environment. The problem of earthwork transportation in foundation pits It has seriously affected the progress of foundation pit construction. [0003] At present, earthwork transportation is mainly...

AI Technical Summary

Problems solved by technology

The lifting equipment is equipped with a lifting platform. The earth truck transports the earthwork in the foundation pit to the ground through the lifting platform. Its installation is all spliced ​​and aligned on site and then welded into a whole. For deep excavation, the overall downward movement mainly depends on the lifting method to separate and move them down, and then assemble and weld them. The cumbersome installation takes up the earthwork construction period, which is very time-consuming and labor-intensive. At the same time, the on-site welding is not environmentally friendly, which indirectly affects the efficiency of earthwork excavation. ; At the same time, the equipment is a customized one-time product, which is only suitable for this project, without the function of reusable turnover, and the economy is poor
