Abstract

The invention discloses a heavy-load equipment hoisting device and hoisting method based on a close deep foundation pit construction environment, the problem of large safety risk caused by poor foundation bearing capacity and high requirement on crane weight in the prior art is solved, and the advantages of meeting the large foundation bearing capacity required by heavy-load hoisting, small hoisting safety risk, convenient construction and low cost are achieved, and the scheme is as follows: the heavy-load equipment hoisting device based on the proximity deep foundation pit construction environment comprises at least one first construction platform arranged on the slope of a foundation pit, wherein the first construction platform is provided with a first reinforcing layer to support a first crane; a second construction platform, wherein the second construction platform is arranged on the top of the structure at the lowest layer and is provided with a turnover platform, and a second reinforcing layer to support a second crane; the second crane hoists the heavy-load equipment to the turnover platform, and then the first crane hoists the heavy-load equipment from the turnover platformto the ground.

Description

technical field [0001] The invention relates to the field of hoisting and hoisting, in particular to a hoisting device and a hoisting method for heavy-duty equipment based on the construction environment close to a deep foundation pit. Background technique [0002] The hoisting of large-scale heavy-duty equipment requires large-scale hoisting equipment, and large-scale crawler cranes are mostly used. The hoisting site should meet the assembly requirements of large-scale crawler cranes. At the same time, the site should also meet the transportation, loading and unloading requirements of heavy equipment. The weight of the equipment determines The foundation bearing capacity of the hoisting site should meet the transportation requirements of large equipment, and the foundation bearing capacity of the hoisting station area of ​​large cranes should meet the safety requirements of hoisting. [0003] The above conditions determine that the hoisting of large heavy-duty equipment has...
