[0003] The communication tower project is an important part of the digital mobile communication system. In the traditional communication tower foundation construction, the longitudinal and transverse positions are usually positioned manually by using a tape measure or a steel tape measure, and the theodolite measurement is assisted to adjust and measure the foundation units one by one, so as to ensure that the horizontal and root opening distance error of each foundation unit is not greater than ±5mm.

The foundation construction method of the new unit combined angle steel tower is different from that of the traditional four-column steel pipe tower or the single-pipe iron tower. The process and precision requirements for foundation construction are extremely high. The foundation engineering of the new unit combined angle steel tower has the characteristics of scattered sites, small single area, large number of unit foundations, and high coupling degree between data. The horizontality of the tower after assembly cannot be adjusted later, and the root opening and horizontal construction need to be done well during the foundation construction, and it needs to be qualified at one time. When the traditional construction method is applied to the foundation construction of the new unit combined angle steel tower, the operation complexity increases dramatically, and the construction efficiency and construction precision are difficult to guarantee. It has been unable to adapt to the foundation construction work of the new unit combined angle steel tower. UTILITY MODEL CONTENTS

[0042] During the construction of the traditional iron tower foundation, 60 minutes are required to adjust and install a single foundation column. Taking a 40-meter-high unit combined angle steel tower as an example, a total of 12 foundation columns are required, and it takes about 12 hours to complete the installation and adjustment of the root opening and the levelness of the foundation columns of an iron tower foundation. Finally, the overall levelness of the foundation columns needs to be adjusted, and a total of nearly 2 working days of construction time is required. The qualified rate of the poured foundation is low.
