Description

  TECHNICAL FIELD The present invention relates to a water stop test apparatus, which can confirm the water stoppage of a butt portion of a flexible water stop member that stops a joint portion of a concrete structure such as a reservoir or a water channel. The test can be performed under the same load conditions as the installation state of the water-resistant water-stopping member.

  In large-scale concrete structures that make up reservoirs and water purification ponds that store domestic and industrial water, etc. It is generally performed.

  Various proposals have been made regarding the joint structure of a concrete structure, but in general, a flexible water-stop member in which a slack is formed in the width direction of the joint part is provided in the structure in order to prevent water leakage. .

  For example, as shown in FIG. 8A, the conventional joint structure and countermeasures against water leakage are groove-shaped at the center of a flexible water-stop member 3 made of rubber or the like with respect to the joint part 2 of the concrete structure 1. An anchor bolt 4a and a nut 4b serving as a fixing tool in which a joint portion 2b in which two rows of parallel projections joined to a flat plate or a housing on both sides are closed are closed by the stretchable portion 3a. It is fixed to a concrete structure 1 which is a frame.

  Then, by tightening the nut 4b, the adhesive portions 3b such as the projections of the flexible water-stopping member 3 are crushed and pressed against the surface of the concrete structure 1 which is a casing to prevent water leakage from the joint portion 2. doing.

  In such a joint structure, when the tightening force of the nut 4b is not uniform or when the fitting portion 3b such as the protrusion is crushed, the water stop performance is not sufficiently exhibited. There may be a test to check the water stoppage after construction.

  For such a water-stopping confirmation test, for example, a test apparatus disclosed in Patent Document 1 is used.

  As shown in FIG. 8 (b), the test apparatus 10 includes an outer tube 11 and an intermediate tube 12, and the outer tube 11 has a cylindrical shape with a closed upper end. A hole 13a is formed, and a screw 13b is formed on the outer peripheral portion to form a connecting portion 13 for connecting a connection pipe 14 for supplying a sample from the leakage confirmation sample supplying portion, and a packing (O-ring) 15 is provided at the lower end. A flange 11b having a groove 11a is formed.

  The middle tube 12 has a shape similar to that of the outer tube 11 and is disposed inside the outer tube 11 and supported by the coupling members 16 from four directions, and the test device 10 is attached to the anchor bolt 4a on the inner periphery thereof. A female screw 12a is formed.

  In such a test apparatus 10, the middle tube 12 disposed inside the outer tube 11 is attached by being screwed to the anchor bolt 4 a via the presser plate 17, and is attached to the flange 11 b at the lower end of the outer tube 11. When the supply of water or the like is received in the outer pipe 11 by the packing 15 such as an O-ring, the leakage from the outer pipe 11 is prevented.

  And the water etc. which are a leakage confirmation sample are supplied to the coupling | bond part 13 of the outer tube | pipe 11 from the pipe 14 connected to the sample supply part which is not shown in figure.

  Thereby, the test space A between both protrusion rows of the flexible water-stopping member 3 is connected to the inside of the outer tube 11 of the test apparatus 10 via the bolt hole of the flexible water-stopping member 3 and the bolt hole of the holding plate 17. If there is a problem with the water-stopping property of the flexible water-stopping member 3 due to the communication, the supplied water leaks from the edge of the flexible water-stopping member 3, and the water-stopping defect portion is simple. Can be confirmed.

However, when the test device 10 is attached, the tightening force applied to the flexible water-stopping member 3 through the presser plate 17 increases or decreases, and the water-stopping state is different from the original tightening force by the anchor bolt 4a and the nut 4b. There is a problem that it becomes an examination.

  In addition, since the flow path for supplying test water or the like supplied into the outer tube 11 to the test space A by the flexible water-stopping member 3 is performed using the gap between the screws of the anchor bolt 4a and the nut 4b, There is also a problem that the test water supplied in the test space A after the test remains without being removed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the water stop structure using the flexible water stop member 3 fixed by a boltless type (clamp method) in which the water stop test apparatus 20 is installed and the water stop test is performed is as a casing. A flexible water-stopping member 3 is disposed across the joint portion 2 between the concrete structures 1 and 1, and the flexible water-stopping member 3 is folded in a substantially Ω-shape at the middle portion in the width direction of the long band. In addition to the expansion / contraction part 3a constituted by the folding part, flat plate-like attachment parts 3b are provided at both ends in the width direction, and are constituted by an elastic member such as rubber or synthetic resin.
Then, the pressing member 18 is applied to the attachment portion 3b of the flexible water-stopping member 3, and the fixed arm member 19 in which the base end portion 19a is placed on the concrete structure 1 and the intermediate portion 19b is supported and fixed to the anchor bolt 4a. By pressing the holding member 18 with the distal end portion 19c, the holding member 18 at a predetermined position can be easily handled even if the anchor bolt 4a is displaced to prevent interference with a reinforcing bar or the like. The flexible water stop member 3 is attached by pressing.
According to the boltless type (clamp system) mounting structure in which such a flexible water-stopping member 3 is supported and fixed by using a fixed arm member 19 without being directly fixed to the concrete structures 1 and 1 by the anchor bolt 4a. For example, the flexible water stop member 3, the presser member 18, and the fixed arm member 19 can be manufactured even before the attachment position of the anchor bolt 4a is determined.

  The water stop test device 20 applied to such a boltless type (clamp type) flexible water stop member 3 is installed in place of the presser member 18 that presses the attachment portion 3b and is provided at the water stop test position X with a guide hole 21a. Is formed, and the guide hole 21a enables a test hole 22 communicating with a test space (water-proof test space) A between the flexible water-stopping member 3 and the concrete structure 1 as a casing to be drilled. The length of the member 21 (see FIG. 3A) may be different from that of the presser member 18 that is installed in place of the test guide member 21, but the cross-sectional shape is the same shape and attached in the same state. A test presser member 23 (see FIG. 3B) that can be held in the same water-stopped state as the surface of the test hole 22, and is attached to the test presser member 23 in a watertight state and can communicate with the test hole 22 And pressurization Constructed and a body feed means 24 and the water cut determination means 25 and the connectable pressurized fluid supply member 26 (see FIG. 2).

  That is, in this water stop test apparatus 20, as shown in FIG. 2, a test hole 22 is formed at a water stop test position X arbitrarily defined in the butt portion 3b of the flexible water stop member 3, and this test is performed. The pressurizing fluid supply member 26 attached to the test presser member 23 in a watertight state is set by holding the test hole 22 with the test presser member 23 to keep the flexible waterstop member 3 in the water stop state under the same load conditions as usual. The pressurized fluid is supplied from the pressurized fluid supply means 24 to determine that the pressurized state is maintained by a water stoppage determination means 25 such as a pressure gauge.

The test guide member 21 of the water stop test device 20 is attached in place of the presser member 18 applied to the attachment portion 3b of the flexible water stop member 3, and the length may be different. The cross-sectional shape is the same as that of the pressing member 18, and a guide hole 21 a is formed in the bottom surface 21 b in contact with the attachment portion 3 b. The guide hole 21a is formed to be larger than the test hole 22 and is sized so as not to interfere with the drilling member when the test hole 22 is drilled.
The test guide member 21 is fixed by the fixed arm member 19 in the same manner as the presser member 18 after the presser member 18 fixing the flexible water blocking member 3 is removed.
Then, the test hole 22 is formed by penetrating from the guide hole 21a of the test guide member 21 to the attachment portion 3b. Normally, when the flexible water stop member 3 is attached to the concrete structure 1, butyl rubber or the like is laid on the surface of the concrete structure 1 so as to eliminate unevenness. It is confirmed that the test hole 22 is formed.

For example, a drilling member 30 as shown in FIG. 4 is used for drilling the test hole 22. The test piece 22 is cut into a cylindrical shape along the outer diameter of the test hole 22, and the cylindrical attachment member piece 31 is cut out. Is used as a punching member 30 that can be taken out from a takeout hole 30 a on the side surface of the punching member 30.
In this way, the adhesive member piece 31 cut out in a cylindrical shape from the test hole 22 is used for backfilling the test hole 22 after the water stop test.
Further, the drilling can be performed using a normal drill. In this case, it is only necessary to use a rubber plug of substantially the same shape separately prepared for backfilling the processed hole as the attachment member piece 31, and even if it is cut out, it is backfilled with a separately prepared one. You can also

The test holding member 23 of the water stop test device 20 is attached after the test guide member 21 is removed after the test hole 22 has been drilled, and the flexible water stop member 3 is fixed. The holding member 18 has the same cross-sectional shape, is fixed through the fixed arm member 19 in the same state, and can reproduce the water-stopped state, and communicates with the test hole 22 on the bottom surface 23a in contact with the attachment portion 3b. A test pipe 26a to be a pressurized fluid supply member 26 is attached to the bottom surface 23a in a watertight state.
As shown in FIG. 3 (b), the test pipe 26a constituting the pressurized fluid supply member 26 penetrates through the bottom surface 23a of the test presser member 23 and projects an end downward, Is welded to form a watertight state, and a connecting screw 26b is formed at the upper end. Then, as shown in FIG. 2, a branch pipe 26c is connected to the connecting screw 26b, and the pressurized fluid from the pressurized fluid supply means 24 is supplied from one side through the branch pipe 26c, and the other side is supplied. Is configured to determine whether or not the pressurized state is maintained by connecting a water stoppage determining means 25 such as a pressure gauge. An air vent cock 26d is provided through the branch pipe 26c so that air in the pipe can be vented when the pressurized fluid is supplied.

  In this test pipe 26 a, the protruding portion at the lower end is located in the hole of the test hole 22, but it is not in a watertight state but in a state where a gap is formed, and the bottom surface 23 a of the test holding member 23 is formed. The flat contact with the back side surface (lower surface) is maintained, and the same water-stopping state as that of the normal pressing member 18 is thereby maintained.

  When the test pipe 26 a is welded and sealed on the back side (lower surface side) of the bottom surface, the size of the test pipe 26 a and the test hole 22 are set so that the weld bead does not interfere with the test hole 22. Is defined (see FIG. 5A).

  Further, the size of the test hole 22 is reduced, the diameter of the test pipe 26a is increased, and it is prevented from protruding from the bottom surface 23a of the test presser member 23. The same water stop state may be maintained (see FIG. 5B).

  In any case, the water-stopping state between the test pipe 26a and the test hole 22 is ensured only by the bottom surface 23a of the test pressing member 23 coming into contact with the surface of the test hole 22, and the O-ring. The same load condition as that in the normal state is ensured by setting the sealing state without interposing a gasket or packing.

In this way, the test pressing member 23 is arranged instead of the normal pressing member 18 so that the test pipe 26a communicates with the test hole 22 and the fixing arm member 19 has the same tightening torque as that of the normal flexible waterproofing member 3. Tighten with.
Then, the back surface of the bottom surface 23a of the test pressing member 23 and the flexible water-stopping member 3 are in a water-stopping state, and the surface of the test hole 22 is also in a water-stopping state with the same load state.

After the preparation for the water stop test is completed in this way, a test pressurized fluid is supplied from one of the branch pipes 26c connected to the test pipe 26a via a pressurized water pump or the like constituting the pressurized fluid supply means 24. The air is discharged and brought into a pressurized state. In addition, a pressure gauge or a pressure sensor constituting the water-stop determining means 25 is attached to the other of the branch pipes 26c connected to the test pipe 26a to detect whether the pressurized state is maintained, and the water-stopped state is visually checked. Monitor.
The water-stopping determination condition in this water-stopping test is determined, for example, by setting the pressurizing pressure to 0.12 MPa, the allowable lowering pressure to 0.01 MPa or less, and the holding time to 5 minutes or more.

  After performing the water stop test and confirming the water stop state, the test holding member 23 is removed, and the adhesive member piece 31 cut out when the test hole 22 is formed in the test hole 22 is adhesive. Glue and backfill with.

It has been confirmed that the original water stoppage can be secured by adhering the adhesive member piece 31 cut out to the test hole 22, and a new test hole 22 is provided next to the backfilled test hole 22. When formed and subjected to a water stop test similar to the above, water leakage from the backfilled test hole 22 was not recognized, and it was confirmed that water stoppage was secured.
After the test hole 22 is backfilled in this way, the original presser member 18 is applied to the attachment portion 3b of the flexible water blocking member 3 and is pressed by the fixed arm member 19 to complete the restoration.

  According to such a water stop test device 20, a test hole 22 can be formed, pressurized fluid can be supplied from the test hole 22 and water pressure can be applied, and a conventional bolt-nut screw gap can be applied. Compared to the case where water pressure is applied, the water stop test can be performed by applying water pressure in a short time.

  Further, the water stop test can be performed at an arbitrary position as long as the space required for the installation of the water stop test apparatus 20 is small and the test hole 22 can be formed. There is an advantage that the water stop test can be performed regardless of the test place, compared to the case where the water stop test can be performed only with.

  Furthermore, although the test hole 22 is drilled for the water stop test, the load condition for ensuring the water stop state can be kept the same as the original water stop state, It is possible to reliably perform a water stop test in a construction state without requiring a seal or an O-ring for sealing.

  Further, in the water stop test device 20, a test guide member 21 and a test presser member 23 can be prepared and replaced in place of the original presser member 18, and the test can be performed. The water stop test can be easily performed by diverting to the flexible water stop member 3.

Next, the case where the water-stopping test apparatus 40 of the present invention is applied to the flexible water-stopping member 3 attached directly to the concrete structures 1 and 1 via anchor bolts will be described with reference to FIGS.
This flexible water-stopping member 3 has the same structure as the flexible water-stopping member 3 already described, and the method for attaching the concrete structures 1 and 1 to the joint portion 2 is shown in FIG. So that it is different.
That is, the flexible waterproofing member 3 is an elastic part at the center of the flexible waterproofing member 3 formed of a flexible material such as rubber with respect to the joint portion 2 of the concrete structure 1. 3a is arranged on the joint portion 2 so as to straddle, and is configured to include a mounting portion 3b in which two rows of parallel protrusions are formed to be bonded to the frame which is a flat plate or concrete structure 1 on both sides, It is installed in a state of being in close contact with the concrete structure 1 which is a frame via anchor bolts 4a and nuts 4b as fixed fastening members and a flat presser plate 17 which are planted in the concrete structure 1 which is a frame. The water leakage from the joint portion 2 is prevented by the flexible water stop member 3.

The water stop test jig 40 for testing the water stop state of the flexible water stop member 3 includes a flat plate-shaped test guide member 41 to be attached instead of the presser plate 17.
As shown in FIGS. 6 and 7, the test guide member 41 is formed with two anchor bolt mounting holes 41a so that the test guide member 41 can be fixed by at least two anchor bolts 4a. At least one guide hole 41b, which is a guide for drilling the working hole 42, is formed in the illustrated example.

The test guide member 41 is also used as a test presser member 43 so that a water stop test can be performed without removing the test guide member 41 as it is, and corresponding to the position of the guide hole 41b on the upper surface of the test guide member 41, A ring member 43b having a female screw 43a having a diameter larger than that of the guide hole 41b is attached by welding or the like. When the test pressing member 43 and the test guide member 41 are used together, the ring member may be omitted by forming the female screw 43a in the guide hole 41b (see FIG. 7).
The lower end portion of the test pipe 44a constituting the pressurized fluid supply member 44 is screwed into the female screw 43a of the ring member 43b so as to be connected, and the upper end portion of the test pipe 44a is also connected. A screw 44b is formed. A branch pipe (not shown) can be connected to the test pipe 44a in the same manner as the pressurized fluid supply member 26, and the pressurized fluid from the pressurized fluid supply means is tested from one side via the branch pipe. The other pipe 44a is supplied with water stoppage determining means such as a pressure gauge to determine whether the pressurized state is maintained.
Further, in the water stop test device 40, an air vent cock is provided via a branch pipe so that air in the pipe can be vented when a pressurized fluid is supplied.

  In the water stop test device 40 configured as described above, the test plate 17 holding the flexible water stop member 3 is removed from the anchor bolt 4a, and then the test guide member 41 and the test press member 43 are combined. The guide member 41 is fixed with the anchor bolt 4a and the nut 4b using the two anchor bolt mounting holes 41a.

  Thereafter, using the guide hole 41b of the test guide member 41, using the drilling member 30, the test hole 42 is drilled in the adhesive portion 3b of the flexible water-stopping member 3, and the adhesive member piece is cut out. Store 31.

  Thereafter, in order to use the test guide member 41 also as the test pressing member 43, the test pipe 44a constituting the pressurized fluid supply member 44 is screwed and connected to the female screw 43a of the ring member 43b. Further, the branch pipe is connected to the connecting screw 44b at the upper end of the test pipe 44a.

After completing the preparation for the water stop test in this way, pressurized fluid for testing is supplied from one of the branch pipes connected to the test pipe 44a via a pressurized water pump or the like constituting the pressurized fluid supply means, and the internal air Is discharged and brought into a pressurized state. In addition, a pressure gauge or a pressure sensor constituting water-stopping determination means is attached to the other branch pipe connected to the test pipe 44a to detect whether the pressurized state is maintained, and the water-stopped state is monitored visually. .
The water-stopping determination condition in this water-stopping test is determined, for example, by setting the pressurizing pressure to 0.12 MPa, the allowable lowering pressure to 0.01 MPa or less, and the holding time to 5 minutes or more.

After performing a water stop test and confirming the water stop state in this manner, the test pressing member (also used as the test guide member 41) 43 is removed and cut out when the test hole 42 is drilled in the test hole 42. The adhesive member piece 31 is backfilled with an adhesive.
Note that the backfilling of the test hole 42 is not limited to the case where the cut-out adhesive member piece 31 is used, and a rubber plug or the like having the same shape and the same material prepared separately may be used.

  After the test hole 42 is backfilled in this way, the original presser plate 17 is applied to the attachment portion 3b of the flexible water blocking member 3 and tightened with the anchor bolt 4a and the nut 4b to complete the restoration.

  According to such a water stop test device 40, a test hole 42 can be formed and pressurized fluid can be supplied from the test hole 42 to apply water pressure, and from a conventional gap between the bolt and nut screw. Compared to the case where water pressure is applied, the water stop test can be performed by applying water pressure in a short time.

  Further, the water stop test can be performed at an arbitrary position as long as the space required for installing the water stop test device 40 is small and the test hole 42 can be formed. Compared to the case where the water stop test is possible only with, the water stop test can be performed regardless of the test place.

  Furthermore, although the test hole 42 is drilled for the water stop test, the load condition for securing the water stop state can be kept the same as the original water stop state, It is possible to reliably perform a water stop test in a construction state without requiring a seal or an O-ring for sealing.

  Further, in this water stop test device 40, instead of the original presser plate 17, the test guide member 41 and the test presser member 43 can be used together, or a test can be performed by separately preparing and replacing, A water stop test can be easily performed by diverting to the same other flexible water stop member 3.

In addition, if a pressure sensor is provided as a water-stopping determination means, a change in pressure after a predetermined time has been compared and displayed by a timer, or an alarm is issued if the change exceeds a set value. In addition, it is possible to automatically detect the quality of the water-stopping state, display and alarm it, and further facilitate the water-stopping test.
In the above embodiment, the description of the treatment of the pressurized fluid after the water-stopping test is omitted.
