Problems solved by technology
[0004] At present, the horizontal displacement monitoring of the top of deep foundation pit usually adopts small angle method, direction line offset method, polar coordinate method and other measurement methods. High-quality observation piers. At the same time, in order to achieve ideal observation conditions, the interference of large-scale machinery and equipment on the construction site should be avoided during the on-site monitoring process. In addition, the above monitoring methods need to be equipped with high-precision total stations, which greatly improves Instrument input costs and labor costs

Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0033] Such as figure 1 As shown, it is a horizontal displacement monitoring device at the top of a deep foundation pit support structure disclosed by the present invention. Several groups of reflectors 1 are installed on one side wall of the support plate, and a base 2 is placed on the ground. 2 The lower surface is fixedly connected with four sets of legs 3, and a mounting rod 4 is installed on the upper surface of the base 2, and a laser rangefinder 5 is installed on the mounting rod 4, and the base 2 is provided with a device for driving the mounting rod 4 to rotate. The driving mechanism 6 is installed on the rod 4 and the laser range finder 5 (such as figure 2 ) is provided with an adjustment mechanism 7 for leveling the laser rangefinder 5, and an adjustment member 8 for adjusting the verticality of the reflection board 1 is provided between the supp...

The present invention involves a horizontal displacement monitoring device on the top of the deep -founded pit support structure. A reflective board is installed on the side wall of the side guard board. The base is placed on the ground.On the surface, there is a installation rod, a laser rangefinder installed on the installation rod, a driver mechanism for driving the driver's rotor rotation, and the installation rod and laser rangefinder are used to facilitate adjustment of the level of laser rangefinder level.The regulating mechanism, between the support plate and the reflective board, there is a regulatory part that is convenient for adjusting the reflective board to be set vertically. The laser rangefinder is installed on the installation rod, and the angle between the reflector and the support class.Under the action of the regulatory parts, the reflector is in a vertical state. Through the drive mechanism, the drive mechanism drives the installation pole to rotate, the installation rod drives the laser rangefinder motion, and the laser rangefinder is vertical with each reflector, which is convenient for convenience, which is convenient for convenience.The operator monitors the horizontal displacement of the support plates in real time.
Description
technical field [0001] The construction monitoring involved in the present invention, in particular, relates to a horizontal displacement monitoring device at the top of a deep foundation pit supporting structure and a use method thereof. Background technique [0002] As the scale and depth of foundation pits continue to increase, the forms of supporting structures continue to appear, and the monitoring items of foundation pits also increase. Monitoring Technical Specifications (GB 50911-2013) requires that the horizontal displacement monitoring of the top of the support pile (wall) is crucial to the safety control of the entire foundation pit, and is one of the routine indicators for the safety monitoring of foundation pits of all levels. [0003] The horizontal displacement of the top of the supporting pile (wall) is mainly caused by the excavation of the foundation pit, the displacement of the slope body into the pit, and the deformation of the supporting members. The la...
