Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water barrier confirmation tester used for confirming the water barrier after construction in the water barrier construction of dam slopes and other structures that require water barrier.

[0002]

[Prior art]

 It is well known that when constructing dam slopes and other structures that require impermeable properties, paving an impermeable layer of asphalt on the surface of the structure. By the way, in the construction of this impermeable layer, of course, it is an essential construction management item to confirm the water impermeability after construction. In particular, confirmation of the water impermeability of construction seams is an important management item.

Therefore, conventionally, confirmation has been made using a vacuum test apparatus as shown in FIG. That is, the generator A, the cord reel B of the cap tire cord, the vacuum pump (compressor) C, and the vacuum tester D are brought to the site, and these are connected as shown in the drawing to perform the vacuum test. Configure the device.

Then, the vacuum pump C is driven by using the generator A in the vacuum test apparatus as a power source, the vacuum tester D is set at a desired test point, and the degree of vacuum at the test point is measured. Therefore, the water barrier was confirmed.

[0005]

[Problems to be solved by the device]

 The conventional water impermeability confirmation test has the following problems because it is carried out by the method described above. (1) The device configuration as means is extremely large. Therefore, in a verification test on a large slope like a slope of a dam and on an inclined surface, an auxiliary worker is required to move the vacuum tester D, which is the main part of it, and the cap tire cords connected to it. To do. (2) The greater the number of test points, the more time and effort it takes to move and install the devices and equipment. In particular, the work was performed on an inclined surface, that is, the work was carried with a safety rope, which had an effect on work efficiency and work safety. The present invention was devised with the object of providing a handy type water blocking confirmation tester that solves these problems.

[0006]

[Means for Solving the Problems]

 As means for achieving the above-mentioned object, the present invention comprises a tester body having a flange portion on the lower surface of the outer periphery, a vacuum gauge, and a manual vacuum pump in the following manner to form a water-impervious confirmation tester. is there.

First, the tester body has a concave portion for forming a vacuum chamber on the bottom surface, and a sealing material filling groove is formed on the lower surface of the flange portion.

Next, the vacuum gauge was attached to the tester body as a means for detecting the degree of vacuum in the concave portion of the tester body.

Further, the manual vacuum pump is connected to the concave portion of the tester body through a suction hose. That is, by operating this manual vacuum pump, the connection was made so that the concave portion of the tester body could be formed in the vacuum chamber. In addition, the tester body and the manual vacuum pump are configured so that they can be carried around by incorporating a portable bag or suspension.

[0010]

[Action]

 Since the present invention is configured as described above, first, in the seal material stuffing groove formed on the lower surface of the flange portion of the tester body, the sealing material, commonly called the putty, is an airtight material. To fill. Then, set the tester body so that it can be pressed onto the test site, that is, on the surface of the impermeable layer. Then, in the set state, operate the manual vacuum pump. Then, the concave portion formed on the bottom surface of the tester body functions as a so-called vacuum chamber. If there is a problem with the airtightness of the test site where the tester body is set, that is, if there is a defect in the impermeable layer construction, this will be displayed on the vacuum gauge. If the points are checked according to the above procedure, it is possible for one worker to efficiently and safely perform a test for confirming the water impermeability.

[0011]

【Example】

 Further, the configuration of the present invention will be specifically described based on an embodiment shown in the drawings. FIG. 1 is a perspective view showing the whole of the water blocking confirmation tester. As described above, the water impermeable confirmation tester is composed of the tester main body 1, the vacuum gauge 2, and the manual vacuum pump 3 as main components. In the examples, as the vacuum gauge 2 and the manual vacuum pump 3, commercially available ones were used, and they were built in and connected to the tester body 1 as shown in the figure. Reference numeral 4 is a suction hose that connects the manual vacuum pump 3 and the tester body 1.

FIG. 2 is a vertical sectional front view of the tester body 1, in which a bottom is provided with a recessed portion 1a that forms a vacuum chamber, and a lower surface of the flange portion 1b is provided with a groove 1c for packing a sealing material 5. Is provided. Then, as shown in FIGS. 1 and 2, the vacuum gauge 2 was attached to the central portion of the recessed portion 1a of the tester body 1 via a flexible joint 2a. That is, the orientation of the display surface of the vacuum gauge 2 was adjusted so that it could be easily seen from the eyes of the tester. In addition, 1d is a connection nozzle of the suction hose 4 for connecting the manual vacuum pump 3 shown in FIG. 1 to the recessed portion 1a of the tester body 1. Furthermore, 1e and 1e are grasping metal fittings when the tester body 1 is set on the surface of the impermeable layer at the test point. In addition, when setting the tester main body 1 at the test point, as described above, the seal material 5 is preliminarily provided in the groove 1c on the lower surface of the flange portion 1b, specifically, as shown in FIG. As for 5, put putty and set.

3 (a) and 3 (b) exemplify a case where the above-mentioned water barrier confirmation tester is configured to be portable. By the way, (a) shows the case where it is stored in the knapsack 6 and can be carried freely, and (b) shows the case where it is configured as a bag storage system.

[0014]

[Effect of device]

 The water barrier confirmation tester according to the present invention is configured as described above with reference to the embodiments, so that it can be used as a large-scale vacuum tester using a conventional generator and a long cap tire cord. By comparison, the following effects can be brought about. (1) The device configuration as a water-impervious confirmation tester is a very simple combination configuration of a tester main body having a vacuum gauge and a manual vacuum pump. That is, it is a compact and so-called handy type. Moreover, the total weight is about 2 kg. As a result, it is easy to carry on an inclined surface such as the slope of a dam, and it is easy to set the tester body to the test point, and it is easy to move from the test point to the test point. That is, an efficient and safe confirmation test can be performed. (2) When setting the main part of the tester body to the test point, stuff a sealing material with a viscosity called putty into the packing groove of the sealing material provided on the lower surface of the flange part of the tester body. Since it is configured to be set with, it is possible to ensure airtightness reliably and easily, and more accurate confirmation of water impermeability can be performed. In particular, in the past, since the bottom surface was flat, it was often the case that the putty applied to the bottom surface had to be sucked into the tester and retested when the degree of vacuum was increased. Since a groove is provided on the bottom surface, the putty does not come off due to this groove, and even an unskilled person can easily perform the test in a short time. As shown in the examples, if a vacuum gauge for reading test results is attached to the main body of the tester with its display surface orientation adjustable, it can be used at a high place such as a dam and even on an inclined surface. Confirmation tests can be safely captured and the test results can be captured without error. (3) The test work itself can be performed by one person, and no special assistant worker is required. As a result, compared to the conventional test, it contributed greatly to labor saving of the measurement work. Moreover, if the storage of the sky test device and the set of manual pumps is configured to be portable, both hands will be free, and it will be possible to move to the next measurement point safely and quickly.
