Foundation reinforcement and protection method for telegraph pole near deep foundation pit
The invention relates to a foundation reinforcement and protection method for a telegraph pole near a deep foundation pit. The foundation reinforcement and protection method comprises the following steps that S1 high-pressure jet grouting piles are driven into the side, near the foundation pit, of the telegraph pole in the direction of an underground wall; S2 a plurality of steel channels are inserted into the high-pressure jet grouting piles; S3 a plurality of steel channels are driven into the two sides of the telegraph pole perpendicular to the direction of the underground wall, and the steel channels on the three sides surround the three sides of the telegraph pole; S4 steel purlins are arranged on the outer sides of the steel channels, and the steel purlins and the steel channels are welded into a whole. The method that the high-pressure jet grouting piles and the steel channels are used for reinforcing the foundation of the telegraph pole is adopted, so that the safety of the telegraph pole and constructors in the excavation process of the foundation pit is guaranteed without the lengthy procedures of removing the telegraph pole of an electric power department; construction progress is accelerated; cost is reduced; in addition, the method is flexible and suitable for various different construction conditions.
