Abstract

A ground damage monitoring element includes a brittle tube, which is a long hollowed tube body made of brittle material, defined therein with an aright space. A sensor is arranged in the space for sensing the pressure change inside the brittle tube. When in use, the ground damage monitoring element of the present invention is buried in a ground to be monitored. Because the brittle tube is made of brittle material, the brittle tube is likely to be damaged if the structure of the ground is changed, resulting in change of the pressure inside the brittle tube. As a result, the sensor can be aware of the ground being damaged and thus send out a signal to notify a remote receiver.

Description

Site damage monitoring component

The present invention relates to a monitoring component, and more particularly to a site destruction monitoring component for monitoring the structural failure of a site.

Taiwan is located at the junction of the plate and belongs to the active orogenic belt. The geological structure is complex. Due to the high frequency of earthquakes, the site is frequently changed. In addition, the summer climate in Taiwan is rainy, and the rainy days tend to make the site soft, if it exceeds the soil and water load. Then it will pour down. Therefore, news of disasters such as earth and stone flow and "walking mountains" are often heard, which often causes great harm. It can be seen that Taiwan's innate geographical conditions are highly challenging, and the destruction of the site is a potential threat that cannot be neglected. However, due to the frequent occurrence of natural disasters, it is necessary to actively face the test. It is true that in the face of natural disasters, the manpower is extremely small. However, if you can prepare for the monitoring of the site changes at any time, you can predict that the disaster will come soon. Evacuate personnel or reinforce work to avoid unnecessary casualties and property damage.

For the above reasons, monitoring site changes is a very important part of maintaining homeland security. There are also many monitoring methods available today, such as long-time aerial photography through satellites to track landscapes. This method covers a large range but cannot perceive subtleties. The change, and too dependent on visual information, may be misjudged (false alarm) or missed (should be detected but not detected). In addition, there is also a method of embedding a detecting instrument under the ground. Usually, this method sets a plurality of instruments in a matrix manner, and each instrument is related to each other, and the ground angle is changed or the relative position is moved by the respective instruments to determine whether the ground is A change has occurred. Although this method can effectively detect more subtle The site changes, but such instruments often need to be equipped with a microcomputer computing system for preliminary data calculation, so the cost is naturally higher, the design is more complicated, and the probability of failure is also added; the light is the detection of the state of the instrument itself, and the maintenance of the fault The instrument needs to be further costly, and it is more likely that the monitoring will be misaligned due to the failure.

In view of this, the main object of the present invention is to provide a ground damage monitoring component which is simple in structure, low in cost, high in sensitivity, and capable of effectively detecting whether the ground disk has changed.

In order to achieve the above object, the site damage monitoring component provided by the present invention comprises a brittle tube, a sensor and a hard rod. The brittle tube is a long hollow tube made of a brittle material, and has a space in an airtight state inside the sensor; the sensor is located in an inner space of the brittle tube for sensing the internal space of the brittle tube a pressure change; the hard rod is an elongated rod made of a hard material, and is coaxially coupled to the brittle tube in a detachable manner; the brittle tube and the hard rod are inserted into a vertical hole provided in the site to be monitored After the hard rod is pulled away, when the site to be monitored changes, the brittle tube will be broken, the pressure in the internal space of the brittle tube will change, and the sensor detects the pressure change to emit The signal of the site to be monitored for damage.

Thereby, the ground damage monitoring component of the present invention is embedded in the ground to be monitored, and if the structure of the ground plate changes, the brittle tube is easily crushed and ruptured, causing a change in the environment inside the fragile pipe, and the sensor is It can be known that the site has been damaged.

Exploded map.

In order that the present invention may be more clearly described, the preferred embodiments are illustrated in the accompanying drawings.

Referring to FIGS. 1 and 2, the site destruction monitoring component 100 of the first preferred embodiment of the present invention includes a frangible tube 10, a sensor 20, a plurality of blade rings 30, a drill bit 40, and a hard rod 50. The brittle tube 10 is an elongated hollow tube made of a brittle material, and has an airtight space inside. The tube body is easily subjected to rupture due to pressure, and the air pressure in the internal space is changed; the sensor 20 is located inside the brittle tube 10, and the pressure change inside the brittle tube 10 can be sensed; each of the blade rings 30 has a The annular connecting portion 32 and the plurality of cymbals 34, each of the blade rings 30 can be sleeved on the brittle tube 10 by the connecting portion 32. Each of the vanes 34 is a sheet-like body that is radially disposed on the periphery of the connecting portion 32. The drill bit 40 is also made of a hard material and has a conical shape, and is disposed at one end of the brittle tube 10, and its tip end extends outward along the axial direction of the brittle tube 10.

The hard rod 50 is used for the convenience of mounting and transporting the fragile tube 10. The hard rod 50 is an elongated rod made of a hard material and is coaxially coupled to the brittle tube 10 in a detachable manner; in the preferred embodiment, the outer diameter of the hard rod 50 is exactly equal to the brittle tube. The inner diameter of 10, and the hard rod 50 is placed in the inner space of the brittle tube 10. Since the hard rod 50 is substantially rigid, when the hard rod 50 is combined with the brittle tube 10, the brittle tube 10 can be protected from the intention. Externally ruptured; conversely, when the hard rod 50 is separated from the frangible tube 10, the frangible tube 10 recovers its susceptibility to damage.

Referring to FIGS. 3-6, the method of installing the site destruction monitoring component 100 of the first preferred embodiment of the present invention includes the following steps:

(1) A vertical hole D (Fig. 3) is drilled vertically on the site to be monitored using a drilling tool.

In order to avoid accidentally destroying the fragile tube 10 which is inherently weak during the installation process, a conventional drilling tool is used in this step, and a vertical hole D for receiving is vertically drilled in the ground. The radius of the longitudinal hole D is greater than the distance between the outer end of the blade ring 30 and the blade 34 of the center of the brittle tube 10.

(2) The brittle tube 10, the blade rings 30, and the hard rod 50 are combined as described above, and inserted into the vertical holes D together (Fig. 4). The drill bit 40 on the brittle tube 10 is inserted first, so that the brittle tube 10 can smoothly enter the vertical hole D.

(3) Backfilling the sand or other suitable filling material between the vertical hole D and the brittle tube 10 (Fig. 5).

(4) The hard rod 50 (Fig. 6) is withdrawn, and the sensor 20 is installed in the internal space of the brittle tube 10, and finally the internal space of the brittle tube 10 is sealed to make the internal space airtight.

In order to facilitate the removal of the hard rod 50, in the preferred embodiment, the hard rod 50 has a plurality of grooves 52, and the grooves 52 are disposed along the axial direction of the hard rod 50. In this way, air can be injected between the brittle tube 10 and the hard rod 50 through the grooves 52 to make the hard The rod 50 can be easily taken out.

If the site changes in the future, the brittle tube 10 will be crushed and ruptured. At this time, the sensor 20 will detect the pressure change in the internal space of the fragile tube 10, and further send a signal to notify a distant reception. (not shown). The function of the blade rings 30 is to increase the sensitivity of the brittle tube 10, and even if the varying ground plates do not directly act on the brittle tube 10, there is a chance to involve the blades 34 of the blade rings 30, thereby causing the brittleness. The tube 10 is broken.

In the aforementioned installation method, there are two points to be specifically stated:

1). When the site to be monitored belongs to the soft soil layer or the shallow layer monitoring, it is not necessary to drill a vertical hole first; instead, the drill bit 40 is directly inserted into the soil, and the hard rod 50 is directly extracted; No need to backfill the job. It is important to note that since the mounting method described herein is inserted directly into a soft ground, the blade rings 30 must be removed first.

2). The step of backfilling the vertical holes can be performed before the hard rod 50 is withdrawn or after being withdrawn.

Figure 7 shows a site destruction monitoring component 200 of a second preferred embodiment of the present invention comprising a frangible tube 10, a sensor 20, a plurality of blade rings 30, a drill bit 40 and a hard rod 60. The site destruction monitoring component 200 of the second preferred embodiment is substantially identical to the first embodiment, with the difference that the hard stem 60 is a tubular body and the frangible tube 10 is inserted into the hard stem 60. The inner diameter of the hard rod 60 is slightly larger than the distance between the outer end of the blade ring 30 and the blade 34 of the center of the brittle tube 10. Here, the action of the vanes 34 of the blade ring 30 is the same as that of the grooves 52 on the hard rod 50 in the first embodiment, and air can be introduced between the hard rod 60 and the brittle tube 10 to allow the hard rod 60 and the brittle tube 10 can be smoothly separated.

Installation and detection of the ground damage monitoring component 200 of the second preferred embodiment The method is the same as the foregoing, and will not be described here.

The sensor 20 used in the above preferred embodiments is merely an example. In principle, any sensor capable of sensing changes in the internal environment of the fragile tube 10 is not limited to the one shown herein. In addition, the blade rings 30 used in the first and second preferred embodiments of the present invention are used to enhance the sensitivity of the brittle tube 10. In practice, the number of the blade rings 30 can be increased or decreased, or not used at all. Depending on the requirements; the drill bit 40 is also not absolutely necessary, and the drill bit 40 can be omitted in other embodiments if the method of directly inserting the ground plate is not employed.

Therefore, the ground damage monitoring component of the present invention has a simple structure, low cost, high sensitivity, and can effectively detect whether the ground disk changes.

The above is only a preferred embodiment of the present invention, and equivalent structural changes to the scope of the present invention and the scope of the claims are intended to be included in the scope of the present invention.
