Abstract

The present invention relates to the technical field of tunnel construction equipment, in particular to a total station shock absorber for tunnel shield construction, comprising a square frame, a support plate is rotatably installed in the middle of the square frame, and two opposite sides of the support plate are A rotating shaft is fixedly installed on each side, and the rotating shafts are respectively connected to the square frame in rotation. A total station is installed at the center of the top of the support plate, and a tapered weight is fixedly connected to the center of the bottom of the support plate; two columns are symmetrically installed on the upper side of the square frame. , the upper ends of the two columns are fixedly connected with a crossbeam, and a fastening device is provided on the crossbeam; under the action of gravity, the conical weight keeps the supporting plate in balance, thereby filtering the vibration during the construction of the shield tunnel and improving the The measurement accuracy of the total station. In the present invention, by rotating the screw rod, the distance between the two support plates is enlarged, so that they are supported in the hole, and the teeth on the support plates are used to embed in the rock layer or the soil layer, thereby improving the gripping force.

Description

Technical field [0001] The present invention relates to the technical field of tunnel construction equipment, and in particular, a whole station instrument damping device for tunnel shield construction. Background technique [0002] The shield method is a full mechanical construction method in the construction of the mushroom, which is to advance the shield mechanical in the plane, and support the four-week surrounding rock to prevent the collapse of the tunnel through the shield housing and tube sheets. Digging, the cutting device is used for soil excavation. Outside the hole through unearthed mechanical, it is pressurized by jack in the back, and assembles the prefabricated concrete pipe film to form a mechanized construction method of tunnel structure. [0003] When the shield machine is taken, the staff requires a total station to measure the tunnel offset, and when the whole station is installed on the shield structure, the shock generated by the shield machine is measured o...
