Digital drilling equipment for engineering field in-situ measurement and measurement method

Abstract

The invention provides digital drilling equipment for in-situ measurement on an engineering site, and particularly relates to modular design of a digital drilling device, a servo control propelling platform and an adjusting rack, and the adjusting rack can realize position adjustment of the whole digital drilling equipment on a construction site (including the height of the whole digital drilling equipment, the height of the whole digital drilling equipment, the height of the whole digital drilling equipment and the height of the whole digital drilling equipment). The servo control propelling platform can effectively control the drilling distance of the drill bit at the to-be-measured mark point, the digital drilling device can control parameters such as the rotating speed and the torque in the drilling process of the drill bit, while-drilling informatization data of the drill bit can be synchronously obtained and converted into energy characteristics of the mechanical effect in the drilling process, and the drilling accuracy is improved. And the strength of concrete or rock is efficiently obtained. The invention further provides an engineering field in-situ measurement method, operation is convenient, and efficient measurement and high-precision measurement can be achieved.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction and detection, in particular to a digital drilling device and a measurement method for in-situ measurement of engineering sites. Background technique [0002] In the fields of underground engineering and slope engineering such as mines, transportation, tunnels, water conservancy and hydropower, foundation pits, municipal administration, national defense, etc., shotcrete is the most conventional measure for tunnel and slope engineering support, whether it is natural slopes or artificial excavation slopes. The use of shotcrete support can effectively protect the rock mass from being washed by rainwater, prevent weathering and rock mass falling off, and occupy an important position in civil engineering. [0003] The action of shotcrete has the following functions: ① supporting the surrounding rock; ② unloading; ③ filling and reinforcing the rock; ④ protecting the surface ...

Problems solved by technology

[0005] Non-destructive testing method: This method includes rebound method, ultrasonic testing method, ground radar testing method, etc. Although the non-destructive testing method will not cause damage to concrete components, the detected data is only indirect data, which needs to be converted to be able to The concrete strength is obtained, and the error is large

[0006] Destructive testing method: This method includes core drilling sampling method, pull-out method, etc., which will cause damage to concrete structural parts. Among them, the core drilling sampling method is to send the sampling laboratory for inspection. Compared with the non-destructive testing method, The destructive testing method can intuitively obtain the strength value of the concrete, and the testing results will be relatively more accurate, but this testing method has defects such as low efficiency, large manpower consumption, high chance, complicated operation, etc.
