Description

Technical Field

[0001] The utility model relates to the technical field of fan foundation construction, in particular to a positioning tool for fan foundation construction. Background Technique

[0002] During the construction of a wind power generation foundation, according to the coordinate control points on the construction site, including the baseline and the horizontal reference point, the foundation axis is determined, and then the foundation pit excavation line is determined according to the axis. White lime is used for setting out the lines. After the ash lines and axes are checked and verified to be correct, the earth excavation construction is carried out. The earth excavation mainly adopts the method of mechanical construction excavation supplemented by manual cooperation. After the excavation is completed, the foundation pit should be cleaned manually, and after being cleaned, the foundation trench acceptance should be carried out. Then, according to the number of designed cables and optical cables, the required number of cable pipes is calculated and pre-buried for construction, and then the cushion concrete is poured. Debris, soil and loose rocks on the rock foundation should be removed, and it should be washed clean and drained of accumulated water. The cleaned foundation rock surface should be kept clean and moist before the concrete is poured. Before pouring the first layer of concrete on the rock foundation surface, a layer of cement mortar with a thickness of 2 - 3 cm must be laid first. The water-cement ratio of the mortar should be adapted to the pouring strength of the concrete, and the laying construction should ensure good bonding between the concrete and the rock foundation. Then, the foundation ring construction is carried out, and the foundation ring support steel plate is pre-buried. Three steel plate parts with a size of 300×300×20 mm are pre-buried in the concrete cushion. The foundation ring anchor bolt support is installed. The lower end of the foundation ring support frame is connected to the pre-buried foundation plate, and the foundation ring and the support frame are connected by adjusting bolts. The foundation ring is installed. Then, the binding of steel bars, formwork support pouring, formwork removal and earth backfilling, etc. are carried out.

[0003] During the construction of steel bars in the fan foundation construction, cushion blocks are usually set at the bottom steel bars to lift the steel bars by a certain height. The cushion blocks are usually evenly placed by workers. Although the workers evenly place the cushion blocks, because it is placed manually based on experience and alignment is required during placement, the construction is slow. And during the construction, it is found that the positions of some cushion blocks deviate and need to be adjusted. Therefore, a positioning tool for fan foundation construction is proposed to position the placement of the cushion blocks to improve work efficiency. Content of the Utility Model
