Automatic heavy-duty penetrometer with vertical detection

Abstract

The invention relates to an automatic heavy-duty penetrometer capable of vertical detection, which belongs to the technical field of construction survey. Including the base plate, the base plate is provided with a bracket, and a penetrating mechanism is arranged vertically through the base plate, and the top of the penetrating mechanism is connected with a lifting mechanism arranged vertically, and the lifting mechanism is set on the bracket; The bottom is matched with the top of the arc-shaped transition frame; a level is provided on the support, and the level is used to measure the verticality of the support. The invention utilizes the free fall of the piercing hammer to vertically accelerate the falling to detect the ground, and measures the verticality through the horizontal ruler, the positioning is accurate, the bracket ensures the verticality, avoids irregular manual operation, does not need manual force, saves time and effort, and the detection process is more standardized. High detection efficiency and high detection accuracy.

Description

technical field [0001] The invention relates to an automatic heavy-duty penetrometer capable of vertical detection, which belongs to the technical field of construction survey. Background technique [0002] Before the construction of housing construction, road engineering, municipal engineering and water conservancy projects, ground survey is required, one of which is to conduct penetration test detection, which is divided into static penetration test detection and dynamic penetration test detection. The static penetrating test detection is to use the pressure device to press the penetrating rod into the test soil layer at a constant speed. The dynamic penetrating test detection is to use the piercer to fall freely, accelerate the vertical fall, and hammer the ground to form the penetration depth. [0003] The split power penetrometer usually takes the weight area of ​​the piercer as the heavy power penetrometer or the light power penetrometer. For the heavy-duty dynamic p...

AI Technical Summary

Problems solved by technology

[0004] 1. The weight of the piercing hammer is relatively large. Manual force is used to lift it up and then fall freely. It requires the joint efforts of multiple people to operate, and the test process cannot absolutely guarantee compliance with the standard operation, and there are many human factors.

[0005] 2. Manual visual inspection of verticality is required, with large errors and low detection accuracy
