Description

Dynamic sounding instrument

Technical Field

The utility model relates to the technical field of foundation detection equipment, in particular to a dynamic sounding instrument.

Background

Foundation detection refers to detection of foundation soil by using detection technologies such as earthquake, gravity and magnetic force so as to evaluate the quality and bearing capacity of the foundation soil, so that construction technicians can effectively control foundation pressure of a building foundation. The rapid development of economy enables the construction quantity of civil construction engineering in each region to be obviously increased in the future in urban construction, so that the stability of the civil construction foundation construction is ensured for ensuring the quality of the civil construction, and construction enterprises need to pay attention to the application of foundation detection technology, which belongs to the foundation technology of the civil construction, and the concrete application quality directly influences the investigation of foundation construction problems. The foundation detection is the beginning of civil construction, and the high accuracy foundation detection can provide basic guarantee for the construction safety of later stage building, still is related to the safety in utilization and the life of building simultaneously. Therefore, foundation detection has important significance in the aspects of evaluating the bearing capacity of the foundation, improving the earthquake resistance of the building and the like.

With the increasing attention of foundation engineering, research and development and innovation of foundation bearing capacity detection technology have become the focus in the field of foundation detection technology. The existing foundation detection equipment mainly comprises a static sounding instrument and a dynamic sounding instrument. The static penetration tester is used for measuring the foundation penetration resistance by pressing the penetration rod of the touch probe into the test soil layer by using the pressure device so as to determine the bearing capacity. The dynamic sounding detection equipment utilizes the force of the penetrating hammer to control the hammer body to move vertically downwards so that the hammer body impacts the hammer pad, and further applies pressure to the probe rod connected with the hammer pad, so that the probe rod is driven to penetrate into the foundation, the repeated operation is carried out for a plurality of times, and the bearing capacity level of the foundation to be detected is detected according to the number of hammering required by the quantitative depth of the penetrating soil. However, for a foundation with harder soil, a dynamic sounding device is generally used for detecting the bearing capacity of the building because the static sounding device is difficult to penetrate the soil. The standard penetration requirement is formulated, a hammer body with the mass of 63.5kg and the drop distance of 76cm is selected, the touch probe rod is hit through the hammer body, the touch probe rod penetrates into the soil, and the foundation bearing capacity is detected according to the required hammering number when the touch probe rod penetrates into the soil for 30cm, and the foundation bearing capacity is called the standard penetration number N _63.5.

The penetration depth of the penetration rod into the soil and the striking number of the hammer body are taken as main parameters for detecting the bearing capacity of the foundation, the accuracy of the standard penetration number measurement is accurately recorded, and the accurate standard penetration number is the main basis for calculating the bearing capacity of the foundation. The common mode adopted for recording penetration of the feeler lever into the soil is to mark the 15cm and 45cm positions of the feeler lever with fine scale marks respectively, firstly, the feeler lever is penetrated into the foundation, the scale marks at the 15cm position are observed to be at the same level with the ground, the number of hits of the hammer body is recorded, the scale marks at the 45cm position are observed to be at the same level with the ground, and the number of hits of the hammer body corresponding to the 30cm penetration of the feeler lever into the foundation is calculated. However, in the detection process, workers need to record the striking number of the hammer body and the penetration depth of the sounding rod hammer into the soil, and as the workers need to operate the hammer body to repeatedly strike the hammer pad and control the fall distance of the hammer body to be 76cm, the penetration depth of the sounding rod into the soil and the striking number of the hammer body are recorded, so that the operation work of the workers is very complicated, and the measurement work efficiency is affected. In actual operation, fine scale marks on the touch probe rod are easily shielded by silt, dust or clay, so that workers are not clearly identified, the penetration depth of the touch probe rod into soil is not accurately judged by the workers, and meanwhile, counting errors cannot be avoided in complicated operation work of the workers, and the detection accuracy is affected. In addition, when the dynamic feeler gauge is used for detection, the striking of the hammer body can drive the feeler lever to shake, so that the penetration direction of the feeler lever is influenced, and the penetration direction of the feeler lever is inclined, so that the detection accuracy is influenced, and the penetration direction is required to be aligned, so that the detection is very troublesome. Therefore, aiming at the detection work of the vertical performance and the strain performance of the dynamic feeler, there is still room for technological perfection, and an improvement scheme is provided.
