Problems solved by technology
Through the observation method of the level instrument and the total station instrument, it takes a long time to measure repeatedly by the measurer
In recent years, the sensor method has also been used to digitally observe the deformation value. This method is more convenient to control, but the sensor is not economical. In most tunnel constructions, economic benefits are generally not used, or the frequency of use is not high, and safety and security cannot be achieved. Quality Management Requirements
When the sudden displacement of the tunnel vault is large, the unexpected situation cannot be predicted by using the traditional measurement method. When the construction personnel are working on the site, they face great safety problems, which makes it difficult to predict. It has always been the technical personnel and Difficulties explored by safety and quality managers

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings.
[0022] In the figure, a tunnel vault sinking ball observation device of the present invention is mainly composed of a connecting piece 1, a head guard 2, a pipe 3, an assembled rod 4, a base 5, a slot 6, an assembled rod a7, a spring Card 7-1, rod with ferrule 8, ferrule 9, hanging ring 10, mounting head part 11, triangular insertion head 12, plumb line and plumb ball 13, scale 14, support rod 15, tunnel vault 16 composition.
[0023] The present invention is an observation device for the sinking ball of a tunnel vault. The device for observing the sinking ball includes a detection frame, a vertical line and a vertical ball 13, a support rod 14, and a tunnel vault 15. The detection frame consists of a connecting piece 1 , head guard 2, pipe 3, assembling rod 4, base 5, slot 6, assembling rod a7; described base 5 is vertically equipped with assembling rod 4, and the up...

The invention discloses a tunnel arch top settlement plumb observation device. The tunnel arch top settlement plumb observation device comprises a detection frame, an energy-saving lamp bulb, a supporting rod and a tunnel arch top. The detection frame is composed of a connecting piece, a protective head, a through tube, an assembling rod piece, a base, a clamping groove and an assembling rod piece a. The assembling rod piece is perpendicularly installed on the base. A connecting piece is installed at the upper end of the assembling rod piece. The through tube is arranged in the left-right direction of the connecting piece in a sleeving mode. The assembling rod piece a is installed at the upper portion of the detection frame. The clamping groove is formed in the middle of the assembling rod piece a. The clamping groove is sleeved with the rod piece with a ferrule. The ferrule is arranged on the rod piece with the rod piece with the ferrule.
Description
technical field [0001] The invention relates to a building construction detection device and a use method, more specifically, to a tunnel vault sinking ball observation device and a use method. Background technique [0002] Deformation observation and monitoring measurement during tunnel construction are the focus of quality and safety control in the construction process. During tunnel construction, surrounding displacement, vault sinking, surface settlement, and deformation and displacement of surrounding buildings and pipelines are monitoring and measuring The traditional observation method of the vault sinking is to hang the tape measure hanging ring on the vault sinking measuring hook, and use the level to measure the elevation to obtain the vault elevation value. In this method, the step of hanging the tape measure hanging ring on the monitoring hook takes too long, and the 24 monitoring points take nearly 4 hours, and the efficiency is low. The role of the vault sinki...
