Problems solved by technology
However, the length of the sand pile is relatively large, up to more than ten meters to more than 20 meters, and the empirical method cannot guarantee that the entire sand pile is evenly compacted from top to bottom.
On-site supervisors cannot accurately record and supervise the construction quality of the pile body
In addition, affected by geological conditions, the geological environment of each sand pile is different, and the sand requirement of each sand pile cannot be guaranteed to be consistent. In the case of weak strata with high water content, the sand requirement may exceed the design requirement

Embodiment Construction
[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0030] This example aims at the problems existing in the existing sand pile quality control scheme, and provides a supervision scheme that can monitor the compactness of sand piles in real time during the sand pile construction process. This scheme utilizes the principle that there is a corresponding relationship between pile body resistance and pile body compactness, and by monitoring the change of pile body resistance value during the implementation of sand piles, it can accurately determine the real-time situation of sand pile compactness.
[0031] Before the monitoring of this scheme, the test can be carried out to determine the corresponding relationship between the density of sand samples and the resistance under different water content and...

The invention discloses a real-time monitoring system and method for the construction quality of sand piles. The scheme is realized based on a sand pile resistance measurement component and a resistance acquisition analyzer, wherein the sand pile resistance measurement component is set in cooperation with the sand pile to monitor the construction of the sand pile in real time The resistance of the pile body during the process is transmitted to the resistance acquisition analyzer; the resistance acquisition analyzer is connected to the sand pile resistance measurement component, and the sand pile is determined according to the real-time resistance value of the sand pile body during the sand pile construction process collected by the sand pile resistance measurement component. Real-time compactness of sand piles during construction. The solution provided by the invention can realize the real-time dynamic monitoring of the quality of the sand piles during the construction process of the sand piles, can raise the quality control of the sand piles to the construction stage, and effectively guarantee the construction quality of each sand pile.
Description
technical field [0001] The invention relates to a construction scheme of sand piles, in particular to a real-time monitoring and control scheme of sand pile construction quality. Background technique [0002] Sand piles, also known as compacted sand piles, are an effective foundation reinforcement technology. Sand piles can significantly increase foundation bearing capacity, accelerate foundation consolidation, and reduce structure settlement. Compared with traditional foundation reinforcement methods, sand piles have the advantages of short pile-forming period and direct reinforcement effect. Sand pile foundation treatment is widely used in the soft soil foundation of highways and the foundation treatment of deep-water ports and wharves. [0003] At present, the quality control of sand piles is mostly post-event inspection, that is, after the construction of sand piles is completed, sand piles are sampled for inspection. Although this method can ensure that the quality of...
