Description

TECHNICAL FIELD

[0001] The utility model relates to bridge survey technical field especially relates to a soil sampler for bridge survey design of various soil quality. BACKGROUND

[0002] Bridge survey design is a comprehensive engineering process, involving multiple key links and professional techniques. The main purpose of bridge survey is to identify the topography, geomorphology, stratum lithology, geological structure, hydrogeological conditions, etc. of the bridge site area through comprehensive use of geological investigation, drilling, in-situ testing, laboratory testing and other means, to evaluate the stability, uniformity and suitability of the site and foundation, and to provide accurate geological, hydrological and other basic data for bridge design. At the same time, it is also necessary to identify adverse geological phenomena within the bridge site range, such as hidden streams, quicksand, tombs, boulders, shallow gas, etc., to evaluate their possible adverse effects and potential threats on engineering construction. The content of bridge survey is extensive, including but not limited to geological survey, hydrological survey, meteorological survey, seismic effect survey and environmental impact assessment, etc. The specific survey method is determined according to the survey content and actual situation on site, and the commonly used methods include remote sensing, drilling, geophysical prospecting, in-situ testing, laboratory testing, etc. For example, through remote sensing technology, the topographic and geomorphic information of the bridge site area can be quickly obtained; drilling can provide in-depth understanding of stratum lithology and geological structure; in-situ testing can evaluate the physical and mechanical properties of rock-soil mass, etc. Bridge survey usually follows a certain process, including preliminary survey, detailed survey and supplementary survey stages. The preliminary survey stage mainly conducts a general geological investigation and hydrological measurement of the bridge site area, and evaluates the construction possibility; the detailed survey stage conducts in-depth geological exploration and hydrogeological testing on the basis of preliminary survey, and provides detailed geological data for bridge design; the supplementary survey is carried out according to the actual needs during the design or construction process. After the survey is completed, a detailed survey report needs to be prepared according to the survey data. The survey report should include the general situation of bridge engineering, the purpose and task of survey, the method and workload of survey, the result and analysis of survey, the scheme suggestion of foundation, the construction suggestion, etc. The report should be clear, accurate and persuasive, and can provide decision-making reference for relevant departments and units. In the process of bridge survey, quality control is the key to ensure the accuracy and reliability of survey data. This includes calibration and maintenance of survey equipment, training and management of survey personnel, supervision and recording of survey process, etc. Through strict quality control measures, the accuracy and integrity of survey data can be ensured, and reliable basic data can be provided for bridge design and construction.

[0003] The soil sampler for bridge survey and design is a tool specially used for collecting soil samples of bridge foundation, which plays a crucial role in the process of bridge survey and design. The soil sampler is usually made of hard material and has basic components such as a drill bit and a handle. For bridge survey and design, the commonly used types of soil samplers include soil drills, auger soil drills, and electric drills. These tools can be selected according to different soil types and depth requirements to ensure the accuracy and representativeness of sampling. In the process of bridge survey and design, the soil sampler is used to obtain soil samples in the foundation area of the bridge. Through sampling analysis, the physical properties, chemical properties, and mechanical properties of the soil can be understood, providing key data support for bridge foundation design. The working principle of the soil sampler usually involves rotating the drill bit into the soil and guiding the soil sample into the soil sampling cylinder through the handle or mechanical device. For mechanical samplers such as electric drills, they use gasoline or diesel as power, have the advantages of high work efficiency, small vibration, and low oil consumption, and can greatly reduce the labor of soil sampling personnel. In the selection and use of soil samplers for bridge survey and design, multiple factors need to be considered, including sampling depth, soil type, sampling accuracy, portability, etc. For example, in slightly soft soil areas, manual drilling can be used to sample with auger soil drills or soil drills; while in hard soil areas, mechanical samplers such as electric drills may be needed to improve sampling efficiency.
