Foundation reinforcement and protection method for telegraph pole near deep foundation pit

Abstract

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.

Description

technical field [0001] The invention relates to the protection of existing buildings during construction, in particular to a reinforcement and protection method for electric pole foundations adjacent to deep foundation pits. Background technique [0002] At present, with the rapid development of urban construction, urban buildings are rising from the ground, and the buildings are constantly developing into the underground space. Almost all newly-built buildings are equipped with various functional basements. When excavating a foundation pit in the construction basement, it is often encountered that the foundation pit is next to the high-voltage line pole. If it is not dealt with, the pole collapse may occur during the excavation of the foundation pit, and even the construction personnel may get an electric shock. Serious accidents, and the previous solution can only be to coordinate the electric power department to relocate the high-voltage line poles, but the relocation eff...

When excavating a foundation pit in the construction basement, it is often encountered that the foundation pit is next to the high-voltage line pole. If it is not dealt with, the pole collapse may occur during the excavation of the foundation pit, and even the construction personnel may get an electric shock. Serious accidents, and the previous solution can only be to coordinate the power department to relocate the high-voltage line poles, but the relocation efficiency is low, it is difficult to keep up with the pace of construction and development, and high relocation costs and cable costs are also required
