Technical Field
[0001] The utility model relates to a speculum device for detecting the fullness of casing grouting. Background Art
[0002] Prefabricated integral concrete structure is a prefabricated concrete structure that is connected by a reliable connection method and forms an integral part with the on-site cast-in-place concrete and cement-based grouting materials. The "reliable connection method" connects the prefabricated components into a whole to meet the design requirements of "equivalent to cast-in-place". The representative key connection parts mainly include: sleeve grouting connection, grout anchor lap connection, vertical prefabricated component bottom joint, cast-in-place concrete joint surface, etc. The sleeve grouting fullness test is a very important test item.
[0003] At present, there are four main methods for detecting the fullness of sleeve grouting: endoscope method, X-ray method, embedded steel wire pulling method, and embedded sensor method.
[0004] The existing sleeve grouting fullness detection has the following problems:
[0005] 1) Both the pre-embedded wire drawing method and the pre-embedded sensor method require pre-embedded parts to be embedded in advance. In actual applications, embedded parts are frequently damaged on site.
[0006] 2) Both the pre-embedded steel wire pulling method and the pre-embedded sensor method can only perform qualitative testing but not quantitative testing.
[0007] 3) X-ray method can easily cause harm to the human body.
[0008] 4) Endoscopic and X-ray equipment are relatively expensive and not very efficient in practical applications.
[0009] 5) When the endoscope method uses a downward-looking probe for detection in actual engineering, it is easily limited by the space inside the sleeve. Utility Model Content
[0010] The technical problem to be solved by the utility model is to provide a peephole device for detecting the fullness of casing grouting, aiming to use a camera device to detect different grouting states, reduce the equipment improvement cost under the premise of unchanged cost, and improve the scope of equipment use.
[0011] In order to solve the above technical problems, the technical solution of the utility model is: a peephole device for detecting the fullness of casing grouting, comprising a handle, a guide rod, a camera, an adjusting knob and a spirit level; the handle is used to carry the entire peephole device, the guide rod is located on one side of the handle and is fixedly connected to the handle; the camera is located at one end of the guide rod and is connected to the guide rod through the adjusting knob; the adjusting knob connects the camera and the guide rod, and changes the angle of the camera by rotation; the spirit level is located on the handle and is used to detect the horizontality of the handle.
[0012] Furthermore, a connection line is provided on the camera, one end of the connection line is connected to the camera, and the other end is externally connected to the display screen through the handle.
[0013] Furthermore, the camera has two working states, horizontal and vertical, for detecting the grouting state in the casing.
[0014] Furthermore, during the detection process, a grout hole is opened on the top of the casing, and the camera enters the casing for detection in a horizontal state. If it is detected that the grouting on the top and both sides of the casing is full, the fullness is 100%.
[0015] Furthermore, when the grouting at the top and both sides of the casing is not full, the camera is adjusted to a vertical state and enters the sleeve for detection, and the grouting saturation is calculated by the distance between the camera and the grouting surface.
[0016] Furthermore, the level is an adjustable bubble type level, and the movement of the bubble is used to confirm whether the handle is horizontal.
[0017] Furthermore, the guide rod is made of stainless steel.
[0018] Compared with the prior art, the utility model provides a endoscope device for detecting the fullness of casing grouting, which uses an adjustment knob directly between the camera and the guide rod to change the pointing angle of the camera, thereby realizing grouting saturation detection in different states, and then uses the distance between the camera and the grouting surface to calculate the saturation, thereby realizing saturation detection in various occasions, and improving the application scenarios and usage scope of the endoscope.
