Embodiment Construction

[0019] In order to further describe the present invention, a method for fixing a vibration pickup for blasting vibration testing according to the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] Depend on figure 1 It can be seen from the schematic diagram of the fixing method of the vibration pick-up when the prior art adopts the concrete platform base structure that the method for fixing the base of the vibration pick-up in this way is: only dig a shallow groove on the ground surface, and after cleaning out the loose soil in the groove , Pour the concrete table, place steel plate or iron plate on the table, adjust the steel plate or iron plate to the level, after the concrete solidifies, put the shock picker with magnetic base.

[0021] Depend on figure 2 It can be seen from the schematic diagram of the fixed mode of the vibration pickup when the prior art adopts the gypsum base structure that the method for...

Abstract

The invention discloses a fixing method of an explosion vibration testing geophone. An employed fixing pedestal is a T-shaped conical pedestal formed by combining an iron plate (2) with an iron cone (1). Before a three-dimensional geophone (4) is installed and fixed at a field, first of all, the iron cone (1) of the T-shaped conical pedestal is hammered into the ground deep into a soil layer or a weathering layer by use of a hammer, and the iron plate (2) is adjusted to be flush with the ground; and slurry-form gypsum blended by adding water is poured to the iron plate (2) to form a gypsum layer (3), then the lower-portion pedestal of the three-dimensional geophone (4) is placed on the gypsum layer (3), a horizontal bubble at the top of the three-dimensional geophone (4) is adjusted to be at a center position, the X direction of the three-dimensional geophone (4) is oriented towards the center of an explosion area, and after the gypsum layer (3) is solidified, a special-purpose connecting line is used for connecting a monitor with the three-dimensional geophone (4). According to the invention, the employed iron cone (1) at the lower portion of the T-shaped conical pedestal can be deep into the ground according to the thickness of the weathering layer or the soil layer to be connected integrally with the ground, and explosion vibration detected on the pedestal can reflect real vibration intensity of a building at a certain place.

Description

technical field [0001] The invention relates to a method for fixing a vibration testing instrument, in particular to a method for fixing a vibration pickup in an engineering blasting vibration test, and is particularly suitable for fixing the vibration pickup under engineering geological conditions with thick regolith. Background technique [0002] In the engineering blasting vibration test, more than 4 monitoring points need to be arranged along the line between the blasting area and the protection object, and the propagation law of blasting vibration is determined according to the vibration data detected by the vibration pickup at each monitoring point. The vibration pickup is placed on the base of the monitoring point. Whether the base is closely combined with the ground surface is very important, which is related to whether the detected data can truly reflect the vibration intensity of the particle at this position. There are two kinds of fixing methods for the existing ...
