A detection device for the thickness of foundation engineering construction sediment

Abstract

This application relates to a detection device for the thickness of foundation engineering construction sediment, which includes a detection rod, the outer peripheral surface of the detection rod is surrounded by a plastic film, the lower end of the plastic film is sealed and fixed with the outer peripheral surface of the detection rod, and the upper end of the detection rod is provided with an operation panel. The lower end of the plate is provided with a measuring cylinder around the probe rod, the upper end of the plastic film is connected to the lower end of the measuring cylinder, and forms a cavity for containing water with the outer peripheral surface of the probe rod; A counterweight ring is sleeved, and the lower end surface of the operation panel is provided with a guide rod that runs through the counterweight ring, and the lower end of the guide rod is provided with a limit piece; The lower end of the plastic film abuts, the liquid level in the plastic film is flush with the lower end of the measuring cylinder, and the upper end surface of the limit piece abuts against the lower end surface of the counterweight ring. The application has the effect of facilitating detection personnel to accurately measure the sediment thickness.

Description

technical field [0001] The present application relates to the field of mechanical equipment, in particular to a detection device for the thickness of foundation engineering construction sediment. Background technique [0002] In the construction of foundation engineering, cast-in-situ pile foundation is a commonly used foundation construction method. Generally, cast-in-place pile foundation first drills deep holes on the ground, then lifts it into the steel cage for making pile foundation, and finally pours cement into one body. , thus completing the construction of the pile foundation. However, during the construction process of drilling, due to the excavation and cutting of the underwater soil, sediment will inevitably be generated in the hole, and the existence of sediment at the bottom of the hole will inevitably cause the settlement of the bored pile, thereby reducing its bearing capacity. Therefore, the detection of the sediment thickness in the pile foundation hole i...

Problems solved by technology

[0004] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects: since the length of the measuring probe rod needs to be taken out to measure the entire detection device, if it is necessary to obtain multiple sets of measurement data to improve the measurement accuracy, it is necessary to repeat the detection for many times. It is inconvenient for the testing personnel to pick and place the device, so there is still room for improvement
