With the further development and utilization of wind resources in China, wind generating sets gradually develop to high power and high altitude, and the traditional wind power flexible all-steel tower technology is difficult to meet the requirements of wind generating set towers with large rigidity and large diameter. In recent years, with the popularization of the assembly type concrete technology in China, the application of the piece-by-piece prefabricated assembly type concrete tower barrel in the field of wind power generation becomes common day by day, and the defects of low rigidity and small diameter of the flexible steel tower are effectively overcome. However, the speed and precision of the assembling process of the assembled concrete tower tube piece greatly affect the construction period and the investment cost, and how to ensure the assembling precision and the construction speed of the assembled concrete tower tube piece becomes a new challenge and a new problem to be faced by the assembled concrete tower tube technology in the wind power industry in future.
In the prior art, after the mixed tower member is transported to a wind field site, the mixed tower member is pre-assembled on a pre-assembly platform (a first section of the mixed tower is on a fan foundation) to form a whole section, and then the whole section is hoisted. The principle of 'fillet first and flat plate later' is followed when pre-assembled. After the four fillet members are assembled in place, the four fillet members are mutually independent due to the large height of the members and poor in stability, and are easy to incline under the influence of wind power. If the foundation at the bottom of the pre-assembled platform is not treated in place, uneven settlement can occur under the action of the self weight of the member, so that the member can be inclined.

Preferably, the middle pipe is provided with a plurality of positioning holes along the length direction, positioning pins are movably inserted into the positioning holes, and the end parts of the positioning pins are used for abutting against the outer sides of the end pipes.
Preferably, the end pipe is provided with a positioning member at one end thereof away from the intermediate pipe, and the outer distance between the two positioning members is equal to the inner clear distance between the two fillet members at the diagonal positions.
Preferably, the positioning piece is T-shaped, one end of the positioning piece is inserted into the inner cavity of the end pipe, the other end of the positioning piece is connected with the inner side of the fillet member, and the lower side wall of the positioning piece is connected with the port of the end pipe.
Preferably, the end pipe is provided with a scale area.
Compared with the prior art, the method has the following beneficial effects:
1. the fixing tool at the top of the mixing tower is a sectional type rod piece, can freely stretch and retract within a certain range, and can fix the length of the tool to be the corresponding length by inserting a positioning pin into the corresponding position of a positioning hole; like this, it is applicable in the pre-assembly of four segmental mixed towers of 140m fan, has increased its commonality, and single part length reduces, and it is more convenient to transport and carry.
2. The utility model provides a mix fixed frock in tower top and increased a pair of setting element, remedied for construction convenience and set frock and component connecting hole to the waist type and the poor problem of work precision that leads to.
3. The calibration area is arranged at the corresponding position, the tool position can be measured and rechecked, the deviation of the component is quantified, and whether adjustment is needed or not is judged through comparison and check calculation.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
Example (b): as shown in fig. 1-3, the adjustable top fixing tool for the hybrid tower of the wind generating set steel-concrete tower comprises two sections of end pipes 1 and a section of middle pipe 2, wherein one ends of the two sections of end pipes 1 are movably inserted into two ends of the middle pipe 2 respectively, and the other ends of the two sections of end pipes 1 are connected with the tops of two fillet members 3 located at opposite angles respectively. Specifically, the middle pipe 2 is provided with a plurality of positioning holes 21 along the length direction thereof, positioning pins are movably inserted into the positioning holes 21, and the end parts of the positioning pins are used for abutting against the outer sides of the end pipes 1.
In the implementation process, the end pipes 1 and the middle pipe 2 are all made of steel pipes with the wall thickness of 5mm, wherein the outer diameters of the two end pipes 1 are 60mm, and the outer diameter of the middle pipe 2 is 68mm, so that the end pipes 1 can stretch in the middle pipe 2.
During implementation, the positioning holes 21 are set at regular intervals, the diameter of each positioning hole 21 is 16mm, the middle pipe 2 and the end pipe 1 can be fixed in a mode of inserting the positioning pins, different lengths of the tool are determined, and the tool can be universal when four sections of tower drums are pre-assembled.
