[0002]
[Prior art]
Conventionally, an enveloping side groove having a substantially inverted U-shaped cross section as shown in FIG. 6 is known. FIG. 6 is an exploded perspective view showing a conventional enveloping side groove.
[0003]
As shown in FIG. 6, the side groove 50 of the encapsulated side groove is provided with a horizontal support member 52 having a substantially rectangular shape in the plane direction and vertically extending downward from both ends of the horizontal support member 52. The vertical support member 53 has a substantially rectangular shape in the plane direction. The horizontal support member 52 has the strength and thickness necessary to withstand the load applied in the vertical direction by an automobile or the like passing through a general road, and the vertical support member 53 can withstand the vertical load received by the horizontal support member 52. It has the necessary strength and thickness.
[0004]
The horizontal support member 52 is provided with an opening 54 that has a rectangular shape substantially in the center and is open to the portion sandwiched between the inner side surfaces of the two vertical support members 53 in the width direction. On both sides of the opening 54 in the width direction, support portions 55 configured by a horizontal surface 55a and a vertical surface 55b and supporting the side groove lid 60 are formed.
[0005]
The side groove cover 60 has a rectangular shape in a substantially plane direction, and a concave handle portion 62 is formed at a substantially center of one end portion in the length direction. The contact part 61 supported by the support part 55 of the opening part 54 of the horizontal support member 52 includes a horizontal plane 61a and a vertical plane 61b. The side groove cover 60 has strength and thickness necessary to withstand a load applied in a vertical direction by an automobile or the like passing through a general road when both ends in the width direction are supported.
[0006]
That is, in this encapsulated side groove, the contact portions 61 at both ends in the width direction of the side groove lid 60 are supported by the support portions 55 at both ends in the width direction of the opening 54, and the horizontal surfaces 61 a of the contact portions 61 are supported.

After the side grooves 50 are connected in an adjacent state, mortar or the like is poured into the joint grooves 53a.
[0008]
[Problems to be solved by the invention]
However, in the conventional enveloping side groove as described above, the support portion 55 of the side groove 50 that supports the side groove lid 60 is constituted by the horizontal surface 55a and the vertical surface 55b, and the contact portion 61 of the side groove lid 60 is also horizontal. 61a and a vertical surface 61b. Therefore, since the side groove lid 60 is supported by a flat surface, there is a problem that the side groove lid 60 rattles due to an error that occurs when the side groove lid 60 and the side groove 50 are formed. That is, when molding, there is an error in the parallel accuracy of the adjacent horizontal surface 55a in the side groove 50 and the parallel accuracy of the lower surface in the side groove lid 60. Even if there is a slight error of about several millimeters, when a vehicle or a person passes through the upper surface of the side groove cover 60, the side groove cover 60 rattles and noise is generated. Moreover, molding with such accuracy that does not generate noise is practically impossible by a processing method considering economics.
[0009]
Further, even if the side groove 50 and the side groove cover 60 can be formed with high accuracy, dirt or pebbles are likely to accumulate on the horizontal surface 55a of the support portion 55 of the side groove 50, and it has been necessary to clean it by human hands. In addition, the side groove cover 60 may rattle due to these soils, pebbles, etc., which may cause noise.
[0010]
Accordingly, an object of the present invention is to provide an encapsulated side groove that suppresses rattling of the side groove cover and does not generate noise with a simple configuration.
[0011]

The water bottom surface 21a is formed by leveling the portions substantially evenly.
[0020]
Then, the construction method of the encapsulation type side groove | channel of this embodiment is demonstrated. FIG. 4 is an explanatory view showing the construction status of the encapsulated side groove according to the first embodiment of the present invention, (a) is an explanatory view showing the construction status of the encapsulated side groove according to the side surface direction, and (b) is It is explanatory drawing which shows the installation condition of the encapsulation type side groove | channel by a front direction.
[0021]
As shown in FIGS. 4A and 4B, the side groove 1 of the encapsulated side groove is installed using two support carts 30. The support carriage 30 is provided at a lower portion of the base member 32, a height adjusting portion 31 that is disposed on the upper portion of the base member 32 and can support a heavy object such as the side groove 1 so that the height can be adjusted vertically. The caster 33 is configured to freely support the horizontal movement of the base member 32. When the height of the height adjusting portion 31 of the support carriage 30 is the lowest, the size can be accommodated in the space surrounded by the horizontal support member 2 and the vertical support member 3 of the side groove 1 and the height adjustment is performed. When the height of the portion 31 is made highest, the horizontal support member 2 of the side groove 1 can be supported, and the lower surface of the vertical support member 3 can be separated from the upper surface of the foundation concrete layer 22. In the above description, in order to arrange the side grooves 1 on the upper surface of the foundation concrete layer 22, first, the plurality of side grooves 1 carried by a vehicle such as a truck are encapsulated on the upper surface of the foundation concrete layer 22 with a unic or a crane. Arrange appropriately in the vicinity of the planned construction position of the mold side groove. Then, each side groove 1 is supported by the two support carriages 30 and is appropriately moved in the horizontal direction and the vertical direction to accurately position the installation place, and after determining the installation position, The side groove 1 is temporarily installed with a liner or the like interposed in the gap formed between the upper surfaces of the foundation concrete layer 22, the height adjusting portion 31 is lowered, and the support carriage 30 is removed. When the temporary installation of the first side groove 1 is completed, the temporary support of the adjacent side groove 1 is sequentially performed, and after the temporary installation of all the side grooves 1 is completed, the work is started to hit the finished concrete layer 21.
[0022]
Then, when the work of the finished concrete layer 21 is completed, mortar is inserted into the joint groove 3a of each side groove 1, and all gaps between the adjacent side grooves 1 are filled, and the opening 4 of each side groove 1 is filled. The side groove lid 10 is closed. In each side groove cover 10, the contact portion 11 is supported by the support surface 5 of the opening 4 of the side groove 1, and the upper surface of the horizontal support member 2 of the side groove 1 and the upper surface of the side groove cover 10 are substantially flush.
[0023]
Then, the other construction method of the encapsulated type side groove | channel of this embodiment is demonstrated. FIG. 5 is an explanatory view showing another construction state of the encapsulated side groove according to the first embodiment of the present invention.
[0024]
In FIG. 5, the enveloping side groove is installed along the side of the road, and a vehicle 40 such as a passenger car is passing through the upper surface of the enclosing side groove. In the installation state of the encapsulated side groove as shown in FIG. 5, the upper surface of the side groove is along the road surface of a substantially horizontal road, whereas the bottom surface of the water channel formed inside the side groove is inclined. That is, the enveloping side groove used in the construction shown in FIG. 5 is formed so as to be inclined according to the angle of the water channel in which the lower portion of the vertical support member 3 is inclined. In a normal U-shaped side groove, when the angle between the top surface and the bottom surface of the water is changed according to the site, a side groove molding die must be newly manufactured, and in the case of a special order, it is a very expensive side groove. . However, the enveloping side groove of the present embodiment has a very simple configuration with no bottom member below the vertical support member 3. Therefore, the vertical support member 3 of the standard type encapsulating side groove forming die has a very simple configuration. By extending only the molded part, it is possible to easily provide a side groove that meets the purpose, and the production cost is low. Note that the support carriage 30 is also used in this construction as a matter of course.
[0025]
Therefore, the enveloping side groove of the present embodiment can be easily positioned by the support carriage 30 when positioning on the upper surface of the foundation concrete layer 22, and the unic or crane is required only in the temporary arrangement. No UNIC or crane is required until positioning is completed as in the U-shaped side groove, and it is very safe and the time that hinders traffic is very short.
[0026]
In particular, the encapsulated side groove of the present embodiment has a side groove lid 10 having a contact portion 11 having a curved surface with a convex cross section, and an opening 4 that can be closed by the side groove lid 10 on the upper surface of the horizontal support member 2. At the end of the opening 4 there is a support surface 5 made of a curved surface having a concave cross section substantially similar to the curved surface of the abutting portion 11 of the side groove lid 10, and downward from both ends of the horizontal support member 2. Since the vertical support members 3 are constituted by the side grooves 1 extended from each other, even if a vehicle or the like passes through the upper surface after the construction, the side groove lid 10 does not rattle and no noise is generated.
[0027]
That is, the force received by the support surface 5 that supports the side groove lid 10 is that the support surface 5 is a curved surface, so that a vertical load acting on the side groove lid 10 is applied to the support surface 5 of the side groove 1 from the contact portion 11 of the side groove lid 10. And is transmitted to the side groove 1 and the close contact between the side groove cover 10 and the side groove 1 is improved. Therefore, the force applied to the upper surface of the side groove cover 10 is not distorted and no noise is generated. Further, since there is no flat portion on the support surface 5, pebbles, gravel, soil, and the like are difficult to deposit, and when they are deposited, they are very easy to remove. Moreover, a margin 5 a is formed at the lower end of the support surface 5, and a predetermined gap is formed between the lower end of the contact portion 11 of the side groove lid 10 and the lower end of the support surface 5 of the side groove 1. Therefore, after construction, gravel, soil and the like gather in this gap, and the contact portion 11 of the side groove lid 10 and the support surface 5 of the side groove 1 are maintained in a surface contact state. Furthermore, when a vertical load is applied to the side groove cover 10, the contact surface between the side groove cover 10 and the side groove 1 is a curved surface, so that the direction of action of the force lines is dispersed, and the load applied to the side groove cover 10 and the side groove 1 is increased. It is reduced and the service life is extended.
[0028]
In other words, the enveloping side groove of the present embodiment, in addition to the action and effect of the conventional enveloping side groove, even if a vehicle or a person passes through the upper surface of the side groove lid 10, the side groove lid 10 rattles and generates noise. It does not occur, and pebbles, gravel, soil, etc. are difficult to deposit on the support surface 5 when the side groove cover 10 is removed in the case of installation work or maintenance inspection of the encapsulated side groove 50, and when it is deposited, it is very removed It's easy to do.
[0029]
In the above description, the operation of hitting the finished concrete layer 21 is not necessarily performed after all the temporary installation of the encapsulated side grooves on the upper surface of the foundation concrete layer 22 is completed. The work may be sequentially shifted to the work of striking the finished concrete layer 21 in order from the side groove 1 where the temporary installation is completed.
[0030]
Further, in the above description, the insertion operation of the mortar into the joint groove 3a is not limited after the work of the finished concrete layer 21 is completed. Is temporarily installed, the mortar insertion work may be sequentially performed on the joint grooves 3a between the adjacent enveloping side grooves.
[0031]
【The invention's effect】
As described above, in the encapsulated side groove of the present invention, the shape of the support surface that supports the side groove cover of the opening formed in a part of the horizontal support member is a curved surface, and the contact portion of the side groove cover is also a curved surface. Therefore, since the load received from the side groove cover is dispersed and the adhesion is improved, no noise is generated by rattling when a vehicle or a person passes through the upper surface of the side groove cover. In addition, since there is no flat portion on the support surface, pebbles, gravel, soil, and the like are difficult to deposit, and when they are deposited, they are very easy to remove.
