Abstract

The invention provides a pile soil pressure monitoring system and a pile side soil pressure monitoring method. The technical problems that in the prior art, test element embedding operation is complex, embedding is difficult and inconvenient, and the embedding effect is poor are solved. A cast-in-situ bored pile comprises a pile body and a reinforcement cage, the pile soil pressure monitoring system comprises a testing element and a delivery part, the delivery part comprises a connecting part and an external connecting part, the testing element is connected to the outer side of the external connecting part, the delivery part is mechanically connected with the reinforcement cage through the connecting part, the delivery part at least has a first form and a second form, when the delivery part is in the first form, the testing element is close to the outer side of the reinforcement cage, when the delivery part is converted from the first form to the second form, the testing element moves towards the outer side direction relative to the connecting part along with the external connecting part, and when the delivery part is in the second form, the outer side of the test element is attached to the pile side soil.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a pile-soil pressure monitoring system and a monitoring method. Background technique [0002] Due to the needs of technical research and engineering design, test elements are often arranged on bored piles to test the earth pressure acting on them and analyze their working conditions. The thickness of commonly used soil test elements is 20mm~50mm, with high rigidity, and it can only sense the earth pressure on one side; for the situation that the personnel cannot go down to the designated position to lay the test elements due to factors such as groundwater or insufficient space, the above soil test elements Poor adaptability. In addition, the currently commonly used methods for embedding soil test components on bored piles are hanging cloth method, telescopic rod method, etc. These methods are complicated to operate and bring many difficulties and inconveniences to the con...
