[0002] In recent years, many cities have carried out large-scale river dredging and management projects. In the comprehensive river management survey, the main purpose of the river dredging and obstacle removal survey is to find out the thickness and degree of pollution of the silt and contaminated soil at the bottom of the river. For some areas with appropriate river width and water depth, water operations can be used for survey.

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for describing the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.
[0017] like Figure 1 and Figure 3 As shown, the utility model is a drilling tool for river channel survey, and its structure is as follows: an impact pad 1 of a truncated cone structure used in conjunction with a drilling rig, the lower end of the impact pad 1 is threadedly connected to the upper end of a manual rotator 2, the manual rotator 2 is a cylindrical metal structure, a manual rotating rod 3 is fixedly installed at a symmetrical position in the middle of the cylindrical metal structure, the lower end of the manual rotator 2 is threadedly connected to a semi-closed pipe 4, the lower end of the semi-closed pipe 4 is threadedly connected to the upper end of an outer sleeve 5, a steel pipe 6 is threadedly connected to the lower end of the outer sleeve 5, an impact blade pipe 7 is threadedly connected to the lower end of the steel pipe 6, a core observation hole 8 is opened in the middle of the impact blade pipe 7, and the lower end of the impact blade pipe 7 is an inclined impact blade 9. Figure 2As shown, the half-tube 4 is formed by fastening a left half-tube 10 and a right half-tube 11 through an outer sleeve 5.
[0018] The impact pad 1, the manual rotator 2, the manual rotating rod 3, the semi-closed pipe 4, the outer sleeve 5, the steel pipe 6, and the impact blade pipe 7 are made of steel. The outer diameter of the cylindrical metal structure of the manual rotator 2 is 22-27 cm, and the diameter of the semi-closed pipe 4 is 4-6 cm. The drilling tool can drill 3-5 meters. After the semi-closed pipe 4 is taken out of the drilling tool, it can be opened for observation, measurement and disturbance sampling. The first section of the impact blade pipe 7 adopts a blade angle design for easy drilling. A core observation hole 8 is opened in the middle of the impact blade pipe 7 to facilitate observation of the stratum when the drill is lifted. The drilling tool of the utility model can adopt impact drilling or rotary drilling. When the impact pad is connected to the threaded connection of the drilling tool, hammer impact drilling can be used. Impact drilling is mainly suitable for fill, silt, and sandy soil layers; when the threaded connection is connected to a power device, rotary drilling can be performed. Rotary drilling is suitable for fill, silt, sandy soil, and gravel soil layers.
[0019] The utility model drilling tool can drill holes and take disturbance samples. At present, impact drilling is mainly used. When exploring in waterless areas in the river channel, the drilling footage can be returned. After drilling 1m, the drill can be lifted to take samples and measure the stratum, and then the drilling can be continued through the threaded connection drill. When sampling and exploring in water, if it is not possible to drill in place at one time, the previous drill hole cannot be accurately found underwater after the drill is lifted. At the same time, the underwater silt has poor properties, and the drill hole is likely to collapse after the drill is lifted. Therefore, it is necessary to drill into the original non-polluted stratum at one time, and then extract the drill tool to take samples and measure the stratum at one time.
[0020] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
