Abstract
The invention relates to a device for fixing an explosion vibration measuring sensor on a soil layer, and the device is mainly used for fixing the explosion vibration measuring sensor on the soft soil layer rapidly. The sensor is structurally composed of a substrate, hollow steel pipes, separable bullets and cast in situ cylindrical rigid piles; the substrate is pasted to the sensor, and provided with a level bubble and a compass which are used for determining the levelness and the direction respectively; the hollow steep pipes are connected with the substrate and used for supporting and fixing the substrate; the separable bullets are mounted in the end portions of the hollow steel pipes respectively, can be separated from the steel pipes, and can be wedged into the soil layer under impact of drill steel to form a cylindrical pile wells till a a ground supporting layer; and after that the cylindrical pile wells are formed, filling materials, i.e., quickly hardened concrete, are injected into the pile wells through the ports of the steel pipes till the substrate, and are hardened to form the rigid piles, the ground bottom supporting layer is connected with the ground surface substrate via the rigid piles, and thus, the substrate and the ground supporting layer are coupled, integrated and thus vibration synchronously.
Description
Technical field
The present invention is used for, in engineering explosion, soil layer being fixed Blast Vibration Monitoring sensor.
Background technology
In blasting engineering, for objects such as the optimization to blasting design scheme, the impact evaluation to environment, scientific researches, and the requirement of " shotfiring safety code " GB6722-2014, need to monitor the ground vibration that engineering explosion produces with vialog, concrete monitoring method utilizes sensor to pick up measuring point vibration signal, is then recorded in vialog storer.To the requirement that sensor is fixing be must and measuring point place ground supporting course be coupled as integrally, when vibration wave passes to measuring point, sensor and measuring point place ground supporting course generation associated movement, so just can monitor real vibration data.In addition, because explosion surrounding environment is all often strange for monitoring personnel, leave before explosion that monitoring personnel reconnoitre, the time of vialog of layouting, lay is very urgent again for, so require that vialog and laying of sensor are fixed and must fast, be ensured to complete all preliminary work in the dozens of minutes before explosion is cleared out a gathering place.When being weak overburden layer for burst region surrounding environment, when utilizing vialog to shake with monitoring explosion, the method for fixation of sensor generally has two kinds, the first is on soft layer (namely having the material of the characteristics such as elasticity, plasticity, elastoplasticity), the pin (solid conical of long about 7cm or cylinder) of staying installed on a sensor is used to insert in ground, the friction force F of surface in pin and ground is relied on to fix sensor, this method rig-site utilization more; Second method uses the device of Chinese patent ZL2015204550087 to utilize the lateral resistance of telescopic post tooth in pipe and friction force F to fix sensor.For first method, can fixation of sensor x, y to position, but, in the process of measuring point vibration, when the Dynamic Inertia power that soil layer is more loose, friction force F is less than sensor, will along z to there is relative sliding in pin and ground, namely sensor and measuring point depart from, and data of shaking are inaccurate with finally causing monitored explosion.For second method, when the length of suspension column is less than the thickness of the layer, suspension column does not reach the position of supporting course (hard rock-soil layer), sensor can only apply on soil layer, in the process of measuring point vibration, can there is elastic-plastic deformation and absorbing vibrational energy in soil layer, cause sensor asynchronous with supporting course particle movement.Visible, above-mentioned two kinds of methods all do not reach the requirement of the fixing vibration-measuring sensor of coupling in the soil layer that the layer that comparatively loosens the soil, on-plane surface, the degree of depth are changeable, thus monitoring is less than real vibration data.
Summary of the invention
In order to overcome the deficiencies in the prior art, meet the requirement of laying fixing vialog before explosion fast, the invention provides a kind of device, fixation of sensor fast in the soil layer of soil layer that can be more loose at the scene, on-plane surface, thickness uncertain (change), makes sensor and measuring point place ground supporting course be coupled as one.
The technical solution adopted for the present invention to solve the technical problems is: structure is made up of four parts, and Part I is substrate, and material is aluminium sheet, for pasting sensor, substrate has air level and compass, for determining direction and levelness; Part II is hollow out steel pipe, steel pipe hollow out, can increase with compaction material in conjunction with firmness, steel pipe is connected with substrate, inserts after soil layer and is combined as a whole with compaction material, for supporting fixing base; Part III is detachable bullet, and shape is circular cone cylindricality, is arranged on hollow out steel tube end part, can be separated with steel pipe, diameter is greater than diameter of steel tube, and effect is that in soil layer, wedging forms cylindrical paxilla well under the impact of drill steel, can be suitable for the soil layer of different depth until ground supporting course; Part IV is cast-in-place rigidity pile body, after detachable bullet arrives supporting course formation stake well, rapidly compaction material is injected in stake well from steel pipe opening, until substrate position, just cylindrical rigidity pile body is become after material hardening to be filled, Main Function connects supporting course and earth's surface substrate bottom ground, making substrate and ground supporting course be coupled as one can synchronous vibration, material of body of a pile selects cement fondu, can reach hardening strength within a short period of time, the requirement of sensor to rapidity is laid at satisfied scene.In principle, the combination of these four parts is equivalent to set up a miniature abutment, Part I solves scene cannot paste sensor on weak soil, and determine the problem of direction and levelness inconvenience, steel pipe is made hollow out by Part II, be conducive to compaction material on the one hand, strengthen on the other hand with compaction material in conjunction with firmness, the fixed sturcture pattern of conventional suspension column " head body one " broken by the detachable bullet of Part III, coordinate the cast-in-place rigidity pile body of Part IV, functionally breach by the fixing restriction of conventional suspension column length, how thick Soft Soil Layer have, how dark bullet just can be squeezed into, how dark pile body just can do, until supporting course, reach the object of fixation of sensor under different soil thickness condition, also overcome a difficult problem for on-plane surface fixation of sensor simultaneously, achieving only just can thickness uncertain (change arbitrarily) at the scene by set of device, on-plane surface, sensor and supporting course are coupled as one by weak soil layer.
The invention has the beneficial effects as follows, can, on-plane surface uncertain at thickness, on weak soil layer (namely there is the material of the characteristics such as elasticity, plasticity, elastoplasticity), sensor and measuring point place ground supporting course are coupled as rapidly one, applicability is good, efficiency is high, structure is simple, easy to operate, with low cost.
