Description
Technical Field
The utility model relates to the technical field of rock and soil parameter measurement, in particular to a dynamic compaction settlement observation measuring ruler.
Background
The dynamic compaction method is a foundation treatment method for quickly solidifying foundation soil by utilizing a heavy hammer to fall down a rammer from a certain height so as to improve the bearing capacity of a soft foundation, and in the dynamic compaction construction, two very important parameter standards are included in the construction scheme of the dynamic compaction, namely the hammer collecting standard of the dynamic compaction and the compaction settlement of a compaction pit, and the determination of the compaction settlement of each impact is very important in the dynamic compaction construction. When one point is tamped, the total settlement of the tamping points can be obtained through the tamping settlement table, the tamping pits are leveled on site after the point is tamped, the total tamping settlement after dynamic tamping can be calculated according to the number of the tamping points arranged per hundred square meters, and the data are used for comparing the design elevation of the bottom layer of the building, so that whether the excess earthwork is transported into or is tidied.
A common tamper settlement measurement method is to use a level gauge and a scale. After the ram is aligned to the tamper point, the scale is placed straight on the ram each time, and measurements are made. And when the uniform value of the tamping settlement of the secondary tamping accords with the uniform value in the dynamic tamping hammer standard, the secondary tamping is qualified. The existing measuring method has the following problems: (1) In the whole process, a staff is needed to stand manually, one staff is needed to stand the staff each time, and the other staff is needed to measure, so that the workload of the staff is increased, the staff is required to be stopped for tamping in the measuring time, and the working efficiency is low; (2) Each time the staff is manually erected, the repeated transformation of the measuring points exists, the perpendicularity error of the erected staff is larger, and the measurement error objectively exists due to soil accumulation on the top surface of the hammer and is difficult to eliminate.
