Detailed Description
Example 1
As shown in fig. 1~5, the movable measurement operation platform for the deep foundation pit structure comprises a supporting member 1, wherein one side of the top of the supporting member 1 is provided with a supporting block 5, the other side of the top of the supporting member 1 is provided with a standing platform 4, the supporting block 5 is provided with a sliding forced centering observation pier 8, and the periphery of the outer part of the supporting member 1 is fixedly provided with a protective guard 3. From this structure, operation platform installs through supporting member 1, connects convenient simple and conveniently, but whole recycle, and gliding compulsory thoughtlessly returns heart observation mound 8 can guarantee measurement control's stability, still very big increase measuring range's flexibility.
In the preferred scheme, supporting member 1 is the triangle-shaped frame, and supporting member 1 one side sets firmly a plurality of connection otic placodes 2, connects otic placode 2 through the bolt and fixes it. The supporting member 1 is mainly made of steel materials of the grooves 10, and the supporting member 1 is formed by welding on the basis of the stability of a triangle. And 4 rows of bolts and connecting lug plates 2 are arranged at the consolidation position in the vertical direction, so that the stability of the whole supporting system is ensured fundamentally. The bolted connection is easily dismantled, but operation platform whole cyclic utilization, easy to maintain, maintenance.
In the preferred scheme, the supporting block 5 is a channel steel, and the supporting block 5 and the standing platform 4 are separately arranged. With this structure, the supporting block 5 is the base of the slide rail 6 and is connected with the supporting member 1 in the vertical direction. And the dynamic load of the measuring personnel is directly transmitted to the sliding rail mechanism to influence the stability of the observation pier when the dynamic load is disconnected from the standing platform 4.
In the preferred scheme, a slide rail 6 and a slide block 7 are arranged between the forced centering observation pier 8 and the supporting block 5, the slide rail 6 is fixed on the supporting block 5, the slide block 7 is fixed at the bottom of the forced centering observation pier 8, and the slide block 7 is abutted against the slide rail 6 to slide.
