The stability of measuring points is the basis for the authenticity and continuity of monitoring and measurement data. Therefore, measuring point protection is particularly important for monitoring and measurement work.

[0003] During the construction process, the benchmark is the standard origin for monitoring and measurement throughout the entire construction phase, and is used for engineering surveying and setting out, control network measurement, etc.; building (structure) settlement monitoring, slope displacement and other monitoring are routine monitoring items during construction. Traditional protection measures or protective covers are generally only used to protect settlement monitoring points with small inclination angles such as the ground, and cannot be installed on monitoring points with large inclination angles such as benchmarks, building (structure) settlement monitoring points, and slope vertical displacement / horizontal displacement monitoring points. In actual processes, these measurement points are often damaged by construction and human activities due to the lack of protection measures.

[0004] Therefore, how to strengthen the protection of benchmark points, slopes and other measuring points with large inclination angles is an urgent problem to be solved in this field. Utility Model Content

[0013] Preferably, a protective cover is provided on the upper measuring point protection tube, and a groove for installing a protective nameplate is provided on the protective cover.

[0014] Preferably, the hose is a steel wire hose, and the stretching rotation angle of the steel wire hose is 0-90°.

[0015] Beneficial effects of the utility model:

[0016] 1. The utility model protects the internal settlement nails by the mutual cooperation between the protection cylinder and the hose. When measuring, the upper measuring point protection cylinder is pulled to rotate 90 degrees, so as to measure the internal settlement nails.

DETAILED DESCRIPTION

[0022] The following is a further description of the method of use of the present invention in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-3 As shown, a combined telescopic hose type measuring point protection device is arranged outside the sinking nail 1, comprising:

[0024] The two protection cylinders 2 are a lower measuring point protection cylinder 21 and an upper measuring point protection cylinder 22, wherein one end of the lower measuring point protection cylinder 21 is fixedly connected to the wall on which the sinking nail 1 is installed, and the lower measuring point protection cylinder 21 and the upper measuring point protection cylinder 22 are connected end to end through a hose 3. After the connection,

[0025] When the hose 3 is retracted to the shortest state, the lower measuring point protection tube 21, the hose 3 and the upper measuring point protection tube 22 are all coaxially arranged with the sinking nail 1;

[0026] When the hose 3 is stretched to its longest state, the axis of the lower measuring point protection tube 21 and the axis of the upper measuring point protection tube 22 are perpendicular to each other.

[0027] One end of the hose 3 is connected to the lower measuring point protection tube 21 through a fastening ring 4, and the other end is connected to the upper measuring point protection tube 22 through a snap ring 5. The fastening ring 4 and the snap ring 5 are circular metal parts. A locking groove 41 is provided on the fastening ring 4, and a locking rod 51 is provided on the snap ring 5. When the hose 3 is contracted to the shortest state, the lower measuring point protection tube 21 and the upper measuring point protection tube 22 are fixed and locked by the locking rod 51 and the locking groove 41.

[0028] The upper measuring point protection tube 22 and the lower measuring point protection tube 21 are hollow cylindrical structures with specifications of φ140*50mm and a wall thickness of 5mm.

[0029] One end of the lower measuring point protection tube 21 is mounted on the wall by means of a fixing screw 6 , which wraps and protects the sinker nail 1 . When the hose 3 is retracted to the shortest state, the outermost end of the sinker nail 1 is located inside the protection tube 2 .

[0030] The upper measuring point protection cylinder 22 is provided with a protection cover 7, and the protection cover 7 is provided with a groove 71 for installing a protection nameplate. This is to engrave the measuring point related information on the nameplate, which plays the role of information transmission and warning protection.

[0031] The hose 3 is a steel wire hose, and the stretching rotation angle of the steel wire hose is 0-90°; the length of the steel wire hose is 100mm, and the stretching rotation angle of the steel wire hose is 0-90°. This is to ensure that the upper measuring point protection tube 22 can rotate and protect the interior. At the same time, the steel wire hose has a certain pressure resistance and can form secondary protection.

[0032] Working process:

[0033] Device combination: The steel wire hose is built into the upper measuring point protection tube 22 and the lower measuring point protection tube 21, and is fixed by the fastening ring 4 and the snap ring 5, while locking the steel wire hose

[0034] Position fixing: There is a fixing screw 6 fixing point at the bottom edge of the lower measuring point protection tube 21, and the fixing screw 6 is used to fix the lower measuring point protection tube 21 to the measuring point layout surface.

[0035] When the measurement work is carried out, the connection between the snap ring 5 and the fastening ring 4 is first opened, and the operator rotates the upper measuring point protection cylinder 22 so that the measuring instrument can be placed horizontally on the measuring point; after the measurement work is completed, the operator restores the protection state.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
