Concrete tower mounting levelling method

Abstract

The invention discloses a concrete tower mounting levelling method. The method comprises the steps that step 1, concrete rings are subjected to levelling in advance, wherein step 1.1, the upper surfaces of the concrete rings are divided into N equal portions, and marks are made at wall thickness midpoints of the concrete rings; step 1.2, the wall thickness midpoints of the concrete rings are subjected to measurement of levelness error; step 1.3, according to the value of the levelness error, glass fabric laminated layers of different thickness are selected, and the glass fabric is glued and connected to designated portions by epoxy resin; step 1.4, the steps 1.1-1.3 are repeated until the upper surfaces of the concrete rings reach horizontal accuracy, and the leveled concrete rings are obtained; step 2, the leveled concrete rings are mounted on a foundation layer according to the sequence of the diameter from large to small. The method is economic, simple and feasible, no grouting or large-scale manufacturing device is needed, the operation is easy, and rapid installation can be achieved; meanwhile, accuracy and perpendicularity requirements of tower mounting are guaranteed, the mounting time is shortened, and the tower use and mounting cost is reduced.

Description

technical field [0001] The invention relates to wind power generator technology, in particular to a method for installing and leveling a concrete tower of a wind power generator set. Background technique [0002] There are various types of towers for wind power generating units. Due to the large-scale wind power market and the needs of low wind speed areas, concrete towers have many advantages and are developing rapidly. [0003] The height of the tower is getting higher and higher, generally 80 to 160 meters at present. For the prefabricated short ring concrete tower, it consists of multiple short rings (concrete rings or ring pieces) stacked together, concrete prefabricated parts (prefabricated The short circular concrete tower) the cumulative error has a great influence on the verticality of the overall tower. Because the concrete ring or ring piece cast by the mold has a certain error, the mold with good precision can be controlled within 1~3 mm, or even the error is la...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem of high difficulty and high cost in tower leveling. Using glass fiber cloth and epoxy resin glue as raw materials, a more convenient, fast and low-cost method is used to pre-level the concrete ring , during installation, the same new method as above is used to level the contact surface between the base layer and the concrete ring and the contact surface of the uppermost concrete ring after superimposing several concrete rings, so as to ensure the installation accuracy of the concrete tower
