Problems solved by technology

However, the length of the sand pile is relatively long, 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 demand of each sand pile cannot be guaranteed to be consistent. In the case of weak strata with high water content, the sand demand may exceed the design sand demand

Embodiment Construction

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further explained below in conjunction with specific drawings.

[0030] In view of the existing problems of the existing sand pile quality control scheme, this example provides a supervision scheme that can monitor the density of sand piles in real time during the construction of sand piles. This scheme uses the principle of the corresponding relationship between pile body resistance and pile body compactness, and by monitoring the change of the pile body resistance value during the implementation of the sand pile, the real-time situation of the sand pile compactness can be accurately determined.

[0031] Before monitoring, this program can be tested to determine the corresponding relationship between the density and resistance of sand samples with different moisture content and particle gradations, which can be us...

Abstract

The invention discloses a real-time monitoring system and method for sand pile construction quality. The real-time monitoring system and method are realized based on a sand pile resistance measuring component and a resistance collecting analyzer, wherein the sand pile resistance measuring component is matched with sand piles to monitor the resistance of a pile body during sand pile construction inreal time and transmit the resistance to the resistance collecting analyzer; and the resistance collecting analyzer is connected with the sand pile resistance measuring component, and determines real-time compactness of the sand piles during the sand pile construction according to a real-time resistance value of the pile body during the sand pile construction collected by the sand pile resistancemeasuring component. According to the real-time monitoring system and method for the sand pile construction quality, real-time dynamic monitoring of the sand pile quality during the sand pile construction can be realized, and the quality control over the sand piles can be brought forward to a construction stage, so that the construction quality of each sand pile is effectively ensured.

Description

Technical field [0001] The invention relates to a construction plan for sand piles, and in particular to a real-time monitoring and control plan for sand pile construction quality. Background technique [0002] Sand piles, also called compacted sand piles, are an effective foundation reinforcement technology. Sand piles can significantly increase the bearing capacity of the foundation, accelerate the consolidation of the foundation, and reduce the settlement of structures. Compared with traditional foundation reinforcement methods, sand piles have the advantages of short pile formation period and direct reinforcement effect. Sand pile foundation treatment is widely used in the treatment of soft soil foundations of expressways and deep-water port terminals. [0003] At present, the quality control of sand piles is mostly post-test, that is, after the sand pile construction is completed, the sand piles are sampled and tested. Although this type of method can ensure that the quality...
