Filling, digging and observing device of earth-rock for construction

Abstract

The invention discloses a filling, digging and observing device of earth-rock for construction. The filling, digging and observing device comprises baseboards, support plates and an observing ring, rotary plates are installed at the left side and the right side of each baseboard, idler wheels are arranged below the rotary plates, rotary shafts are installed inside the baseboards, and supports arearranged below the rotary shafts; telescopic rods are fixed to the upper portions of the baseboards, fixing bolts are installed in the middles of the telescopic rods, adjusting blocks are arranged inthe middles of the support plates, and the support plates are located above the telescopic rods; rotary covers are installed in the middles of the adjusting blocks, a connecting telescopic rod penetrates into the rotary covers, a fixed plate is installed below the adjusting blocks, fixed covers are arranged below the fixed plate, measuring point fixing covers are installed below the observing ring, and the observing ring is located below fixing rods. The filling, digging and observing device of the earth-rock for construction is convenient to erect, can be stably placed on the earth surface after the earth-rock is filled and dug, and has a wide measuring range.

Description

technical field [0001] The invention relates to the technical field of observation devices for construction of hydropower projects, in particular to an observation device for earthwork filling and digging for construction. Background technique [0002] Topographic surveying refers to the operation of surveying and drawing topographic maps, that is, the work of measuring the projected positions and elevations of the objects and terrain on the earth's surface on the horizontal plane, reducing them in a certain proportion, and drawing them into topographic maps with symbols and notes. Observation basically adopts the method of aerial photogrammetry. Earthwork filling and excavation operations are required in hydropower projects, and landform observations are required after completion to ensure the rationality of project layout. However, the existing geomorphological observation devices are very difficult to place during installation. Since the placement area is outdoors, the gr...

Problems solved by technology

[0003] The object of the present invention is to provide an earthwork filling and digging observation device for construction, to solve the problem that the existing landform observation device proposed in the above background technology is very difficult to place during installation, and the range of the measured area is small, so it is not suitable for large-scale landform observation devices. The problem of geomorphic exploration of the area
