Description
Technical Field
The utility model relates to a technical field of large-tonnage prefabricated section installation butt joint, more specifically say, relate to a combination hoist of the accurate butt joint installation of the massive prefabricated module of large-tonnage.
Background
Modular design and construction in the engineering field have become a new trend, and both in the marine engineering field and the petrochemical field, or in other fields such as the bridge construction field, etc., gradually tend to be modular design and installation modes. Modular design and construction advantages: firstly, the project construction period is shortened, and the time is the benefit; secondly, the modules can be synchronously built, the construction site is separated from the module design and construction, and the construction efficiency is improved; finally, the modular design and construction technology is an effective construction method for shortening the construction period, improving the construction quality and reducing the construction cost, and the project cost has strong controllability and low construction cost. The modular design and construction correspond to optimization and innovation of a site construction method, the traditional installation and hoisting method is difficult to meet the requirement of project construction, and the continuous adoption of the traditional method can be time-consuming, labor-consuming and financial.
The existing installation butt joint adjustment technical methods in the engineering field have two types:
1. the length of the hoisting rigging is calculated based on a theoretical technology, and the installation of a bridge module is taken as an example. When a common bridge module and a basic module are in butt joint installation, the length of a required rigging is calculated theoretically, then the rigging which meets the calculation result is selected for assembly, and the whole module can be in butt joint under the planned hoisting posture.
However, the length of the common rigging is fixed, and the length of the common rigging in the market is 5m, 10m and the like which are the whole length and the whole meter, and the accuracy of 0.001mm cannot be achieved as theoretically calculated, but the module installation accuracy required by construction cannot be achieved (the installation accuracy of a common bridge is about 2 mm) by performing butt joint installation work according to the method. Even adjusting the final length by tripping does not completely achieve accurate seating. The adjustment result without considering the field change condition, such as the actual field conditions of module deformation, steel expansion and contraction, welding condition, manufacturing and the like, can influence the adjustment of the installation posture finally. If the length of the initially configured hoisting rigging cannot meet the final installation attitude requirement in the hoisting in-place process, the module may be hoisted to the ground again from the air, the rigging length is changed, and the shackle is adjusted, so that time and labor are consumed, the overall construction progress is affected, and the construction cost is increased.
2. The chain blocks (chain blocks) are used, and are added into 4 riggings for connection to serve as final positioning adjustment. The method can meet the requirement of adjusting the construction and installation precision and can basically reach the numerical value required by theoretical calculation. But the largest single chain block on the market has a load-bearing capacity of 50 t. If the large-tonnage chain block is customized, the manufacturing cost of the large-tonnage chain block is exponentially increased, and the conventional tonnage chain block cannot meet the hoisting task of the large-tonnage module at all.
The operation is carried out according to the two traditional hoisting methods, the requirement of the installation and butt joint of the existing large-tonnage precast blocks cannot be met, the problem of the installation and butt joint of the large-tonnage precast blocks needs to be solved from two directions, on one hand, the bearing capacity needs to be met, and on the other hand, the adjustment precision needs to be met.
