Description

  The present invention uses the existing side grooves almost as they are, and can easily construct the side grooves having water collecting performance while shortening the construction period, and the side groove construction method capable of securing the water collecting capacity for a long time after the construction, It relates to the water collecting bracket used for the construction method.

  Conventionally, as a concrete side groove continuously installed on the shoulder of a roadway, there is a side groove having a substantially U-shaped cross section. The conventional type side groove is made of concrete installed in the side groove main body formed in a substantially U-shaped cross section from the bottom and side walls forming a water collecting channel extending in the longitudinal direction inside, and the lid of the upper surface opening of the same side groove main body. The structure is provided with a cover plate.

  According to such a side groove, rainwater that has fallen on the impermeable pavement on the roadway flows to the side groove side along the transverse gradient, and flows down from the water collection hole of the cover plate to the water collection path in the side groove body.

  Impervious paved roads have been used in recent years because of heavy rain and heavy rainfall, the surface of the paved road becomes flooded, causing hydroplaning phenomena during vehicle travel. It is being done. A water-permeable pavement uses relatively large aggregates in the surface pavement and forms a water-permeable gap between the aggregates. Rainwater that falls on the pavement quickly penetrates into the ground from the surface. Rainwater that has not permeated completely passes through the surface layer and is drained into the gutter.

  As side grooves to be installed on the permeable pavement, formwork is used in advance as a two-layer structure in which a permeable concrete layer is combined on a non-permeable concrete layer with a water collecting hole penetrating vertically. The rainwater that passes through the water-permeable surface layer of the permeable pavement is introduced into the permeable concrete layer of the side-gutter lid through the water passage formed on the side wall of the side of the pavement. And the technique of collecting water from the inside of a gutter body through the water collection hole of a water-impermeable concrete layer from there is known (refer patent document 1).

Further, a technique is known in which a side groove lid in which a water collecting hole penetrating vertically is attached to the upper surface opening of the side groove body so that the upper surface of the side groove body is covered with a water permeable surface layer (see Patent Document 2). .

  However, since the side groove of the above-mentioned patent document 1 is manufactured in advance using a mold, the side groove cover is difficult to construct on the site, and in the case of construction on the site, the mold supported by the support material inside the side groove main body. It is necessary to cast concrete in the frame, and it is necessary to install the formwork and remove the formwork, and it is difficult to continue the formwork without interrupting drainage. There's a problem.

  Moreover, although the side groove of the above-mentioned patent document 2 has the advantage that the side groove cover can be constructed in the field, the side groove cover uses a steel plate, invites corrosion due to rainwater, and a part of the corroded steel plate falls into the side groove main body, There is a problem that prevents drainage. Even if the steel sheet is subjected to rust-prevention coating or plating treatment, it has sufficient durability when used in environments with severe corrosion conditions, such as those exposed to corrosive gas, seawater, anti-freezing agents (such as calcium chloride), etc. It is difficult to ensure, and the problem of cost increase due to rust-prevention coating and plating treatment remains.

  Further, in the lateral groove of Patent Document 2, the water-permeable surface layer formed on the upper surface of the lateral groove body is clogged due to accumulation of dust, dust, sand, etc. for many years, the water collecting ability is reduced, and there is a large amount of rainfall. If this happens, the pavement may be flooded. The problem of the clogging of the permeable surface layer is particularly serious in areas where a large amount of rainfall, as well as a large amount of volcanic ash and yellow sand fall.

  The present invention has been made in view of the above-mentioned problems, and it is possible to easily construct a gutter having water collecting performance while using the existing gutter substantially as it is and shortening the construction period. It is an object of the present invention to provide a side groove construction method and a water collecting fitting used in the construction method that can maintain and secure a sufficient water collection capacity of the side groove over a long period of time.

In order to solve the above-mentioned problem, the construction method of the gutter according to claim 1 of the present invention is
Remove the lid from the gutter body of the existing gutter,
On the lid hangings on both side walls of the side groove body, a plurality of new cover plates made of concrete with reinforcing fibers having water collecting holes extending in the groove width direction are installed,
On the upper surface of each of the installed lid plates, a water collecting fitting provided with a water collecting slit that extends while maintaining a predetermined slit width in the length direction of the side groove,
A net is placed on the upper surface of each cover plate other than the mounting surface of the water collecting bracket,
A pavement surface layer is formed from the existing pavement surface layer adjacent to the side groove main body or the upper surface of the roadbed after removal of the pavement surface layer to the entire upper surface of each cover plate around the water collecting slit.

  According to the gutter construction method of the first aspect, the gutter having water collecting performance can be easily constructed on site at a short construction period and with a small construction cost by using the existing gutter substantially as it is. In other words, the existing cover plate is removed and the newly installed cover plate at the opening of the gutter body acts as a permanent mold, eliminating the need for additional work such as removing the formwork after construction. Since the net is laid in advance on the plate, the aggregate of the paving material is held on the net during construction, and the aggregate does not fall from the drainage hole of the lid plate into the gutter body, ensuring the construction and shortening Can be easily constructed on site with a short construction period and low construction costs.

  The cover plate is made of concrete with reinforcing fibers and has high strength, and it is not necessary to support the cover plate with a support material from the bottom when laying or rolling the pavement material. In addition, even if drainage or the like is flowing through the gutter body, the gutter construction can be continued without interruption, contributing to the work efficiency of the construction and the shortening of the construction period.

  Since the cover plate and net made of concrete with reinforcing fiber are used for construction, the side gutter after construction is not subject to corrosion due to rain water as in the case of using steel plate, so the pavement material falls into the side gutter and collects water. Sufficient durability can be ensured even in harsh environments exposed to corrosive gas, seawater, anti-freezing agents (calcium chloride, etc.), etc.

  In addition, as long as the construction method of this invention is a paved road provided with a gutter, the place which can be applied is not restricted to a roadway, a sidewalk, a parking lot, a park, etc.

  In the construction method of the side groove according to claim 2 of the present invention, when the pavement surface layer adjacent to the side groove body is removed from the roadbed, the upper portions of both side walls of the side groove body are cut according to the removal of the pavement surface layer. It is characterized by that.

  The side groove construction method according to claim 3 of the present invention fills a gap formed between both side surfaces of each lid plate and the side wall inner surface of the side groove body in a state where each lid plate is installed on the lid hook. It is characterized by filling the material.

  According to the construction method of the side groove according to claim 3, the gap formed between the lid plate and the side wall inner surface of the side groove main body is filled with the filler to eliminate rattling of each lid plate, Even if vibration or the like during vehicle travel is applied to the water-permeable pavement surface layer laid on the top, it is possible to prevent the pavement surface layer from being cracked or split. In addition, this makes it possible to use an existing cover plate or a mold for forming a cover plate having a small thickness or width with respect to the upper surface opening of the side groove main body as it is, thereby further reducing the side groove construction cost.

  The side groove construction method according to claim 4 of the present invention is characterized in that the water collecting metal fitting is attached to the upper surface of the cover plate with a bolt inserted into a water collecting hole on the upper surface of the cover plate.

  According to the method for constructing the lateral groove according to claim 4 of the present invention, the water collection is performed by utilizing the water collecting hole provided in each cover plate without newly processing a hole for inserting a bolt in each cover plate. A bolt is inserted into the hole, and the mounting portion of the metal fitting body can be attached to the upper surface of each cover plate by the bolt. Thereby, each water collecting metal fitting can be efficiently attached to the upper surface of each cover plate with a bolt, and the work efficiency of construction is excellent.

  According to a fifth aspect of the present invention, there is provided a method for constructing a side groove, wherein a positioning pin is attached to a part of a water collecting metal fitting, the positioning pin is inserted into a water collecting hole on the upper surface of the cover plate, and the water collecting metal fitting is covered. It is characterized by positioning with respect to the plate.

  As described above, according to the method for constructing a gutter according to the present invention, the side gutter having water collecting performance that is continuous from the roadway or sidewalk to the gutter while using the existing gutter substantially as it is and shortening the work period is provided on-site. It can be constructed easily and efficiently. Moreover, the side groove after construction has sufficient durability against corrosion due to rainwater and the like, and has an effect that it can be used in a wide range of environments.

  Furthermore, by attaching a water collecting metal fitting with a water collecting slit to a predetermined position on the upper surface of the cover plate, the water-permeable pavement surface layer is clogged due to accumulation of dust and sand over many years, and the water-permeable pavement surface layer itself collects water. Even when the performance is gradually deteriorated, rainwater flowing on the pavement surface layer is collected from the water collecting slit into the side groove, so that the water collecting performance of the side groove can be maintained and secured for a long time.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 9 show a first embodiment of the present invention. The side groove 1 shown in FIG. 1 is continuously installed on the shoulder of the roadway 30, and is constructed by the construction method of the present invention. Below, the construction procedure of the side groove 1 shown in FIG. 1 is demonstrated.

First, as shown in FIG. 2, the existing cover plate 3 is removed from the existing gutter body 2.
The side groove main body 2 is a concrete block having a substantially U-shaped cross section, and, as shown in FIG. 2, a water collecting passage 4 extending in the longitudinal direction is formed in the internal space by a bottom portion 2a and left and right side walls 2b. The left and right lid hooks 6 on which the removed lid 3 is installed are formed in the upper surface opening 5 of the side groove body 2 so as to be positioned on the inner surface of the upper end of both side walls 2b.

  When the existing cover 3 is removed, the existing impermeable pavement surface layer 32 on the roadbed 31 adjacent to the existing gutter body 2 is removed as shown in FIG. Moreover, according to the removal part of the impermeable pavement surface layer 32, the upper part 2c of the both side walls 2b of the existing gutter body 2 is excised.

  Next, as shown in FIG. 4, a cover made of concrete containing reinforcing fibers having a plate thickness thinner than that of the removed cover plate 3 is placed on the cover 6 located inside the both side walls 2b of the existing gutter body 2. A plurality of new plates 7 are continuously installed. The newly formed cover plate 7 has a plurality of water collecting holes 8 extending through the upper and lower surfaces and extending in the groove width direction (in the example of FIG. 6, two rows in the width direction and four rows in the length direction, a total of eight). Is provided.

  According to the new cover plate 7, the reinforcing fiber is mixed into the concrete, so that the concrete can be cured and solidified to improve the compressive strength, tensile strength, impact property, toughness, and the like. It is possible to increase the strength while reducing the thickness and reducing the weight. Examples of the reinforcing fibers mixed in the concrete of the cover plate 7 include glass fibers, inorganic fibers such as carbon, and fibers such as synthetic resins. For example, a bundle of fibers having a fiber diameter of about 15 μm and a fiber length of about 38 μm is mixed and kneaded.

  The lid plate 7 is thinner than the conventional lid plate 3 shown in FIG. 2, and the thickness T of the lid plate 7 is set on the lid holder 6 of the side groove body 2 as shown in FIG. In this state, the upper surface of the cover plate 7 is substantially the same level as the upper end surface of the side groove main body 2 shown in FIG.

  The width W1 of the cover plate 7 may be the same as the width of the conventional cover plate, but in this embodiment, the width W1 is narrower than the width of the conventional cover plate, that is, the left and right width W1 is the side groove main body. 2 having a slightly smaller size than the width W2 of the upper surface opening 5 can be used. Accordingly, it is not necessary to newly manufacture a dedicated size cover plate from the formwork, and an optimal cover plate can be appropriately selected from a plurality of existing sizes and can be effectively used. In this case, the gap S formed between the left and right side surfaces of the lid plate 7 and the inner wall surface at the back of each lid hook 6 is filled with a filler 9 such as asphalt or mortar as shown in FIG. The rattling between the cover plate 7 and the side groove main body 2 is eliminated.

  Next, as shown in FIG. 5 and FIG. 6, the water collecting metal fitting 10 extending along the curb 33 on the road shoulder is formed on the upper surface of each newly installed cover plate 7 installed on the both lid covers 6 of the existing gutter body 2. Install near the road. In addition, the net 11 is disposed on the uppermost part of the upper surface of the water collecting bracket 10 so as to straddle the lid plates 7.

  As shown in FIGS. 7 (A) and 7 (B), the water collecting metal fitting 10 has an L-shaped metal fitting body 12 and an auxiliary piece 13 which are arranged in parallel with each other while maintaining a predetermined width. A water collecting slit 15 that is connected to each other and communicates in the vertical direction is formed in an inner space between the L-shaped metal fitting body 12 and the auxiliary piece 13 that are arranged in parallel to each other. For example, when the size of the cover plate 7 is length × width × width = 500 mm × 380 mm × 60 mm, the size of the water collecting bracket 10 is set to be slightly less than 500 mm and the width of the water collecting slit 15 is 9 mm. Further, the height of the water collecting metal fitting 10 is the same as the thickness of the water-permeable pavement surface layer 34 constructed on the road bed 31 from the upper surface of the cover plate 7, and is 50 mm for a roadway and 40 mm for a sidewalk. .

  Bolt holes 17 are provided at both ends of the mounting portion 16 of the metal fitting body 12 having an L-shaped cross section of the water collecting metal fitting 10 in accordance with the position of the water collecting hole 8 of the cover plate 7. Therefore, the dedicated bolts 18 are inserted from the respective bolt holes 17 into the water collecting holes 8 of the lid plate 7 immediately below, and the water collecting fitting 10 is attached to the upper surface of the lid plate 7 by the dedicated bolts 18. Further, on the lower surface of the auxiliary piece 13, positioning pins 19 for positioning the water collecting fitting 10 with respect to the cover plate 7 by being inserted into the water collecting holes 8 at both ends are just welded or the like at the same positions as the respective bolt holes 17. Installation is fixed.

  As shown in FIGS. 5 and 8A, the dedicated bolt 18 includes left and right horizontal locking portions 21 through which the water collecting hole 8 can be inserted vertically at the lower end of the bolt shaft 20 and the upper end of the bolt shaft 20. The nut 22 is screwed together. Further, the bolt hole 17 on the water collecting bracket 10 side has a long hole shape extending in the width direction so that the left and right horizontal locking portions 21 at the lower end of the bolt shaft 20 can be inserted as they are.

  A nut 22 is screwed to the upper end of the bolt shaft 20 in advance using the dedicated bolt 18 so that the water collecting slit 15 faces the longitudinal direction near the curb 33 on the upper surface of the cover plate 7 as shown in FIG. The water collecting fitting 10 is disposed on the auxiliary pin 13 and the positioning pins 19 of the auxiliary piece 13 are inserted into the water collecting holes 8 on both ends, so that the bolt hole 17 on the water collecting fitting 10 side and the water collecting hole 8 on the cover plate 7 side As shown in FIG. 5, the horizontal locking portions 21, 21 on the left and right of the lower end of the bolt shaft 20 of the dedicated bolt 18 are temporarily inserted from the bolt holes 17 to the water collecting holes 8 immediately below. Then, the bolt shaft 20 is rotated 90 degrees around the axis.

  When the bolt shaft 20 is rotated 90 degrees, the horizontal locking portion 21 of the bolt shaft 20 is locked to the lower surface of the cover plate 7 as shown in FIG. While preventing the movement, the nut 22 at the upper end of the bolt shaft 20 is tightened. Thereby, as shown in FIG. 9, the water collecting fitting 10 can be attached to the upper surface of the cover plate 7. Further, the water collection slit 15 of the water collection fitting 10 communicates with the water collection channel 4 through the water collection hole 8. In this way, the water collecting metal fittings 10 are attached to the upper surfaces of all the cover plates 7, and the upper surfaces of the cover plates 7 are straddled across the respective cover plates 7 from the mounting surface of the water collecting metal fittings 10 to the most part near the roadway. Then, the net 11 is arranged.

  Next, as shown in FIG. 9, a water-permeable pavement material 23 is laid from the top of the net 11 over the entire top surface of each cover plate 7 excluding the water collecting slit 15 from the top surface of the roadbed 31 and rolled. A water-permeable pavement material 23 is laid around the water collecting fitting 10 in the upper surface of the mounting portion 16 and the space between the auxiliary piece 13 and the curb 33 on the road shoulder. Thereby, the water-permeable pavement surface layer 34 which continues from the upper surface of the roadbed 31 to the upper surface of the cover plate 7 and the inner surface of the curbstone 33 is formed. As the water-permeable pavement material 23, asphalt as a binder is mixed and kneaded with an aggregate made of natural stone, sludge, crushed stone or the like having a particle size of about 3 mm to 10 mm to improve drainage inside the layer. An asphalt mixture having a water-permeable gap and good durability and weather resistance is used. Moreover, you may use a synthetic resin, for example, an epoxy-type adhesive agent, a urethane type adhesive agent, etc. instead of asphalt as a binder. Such a water-permeable pavement surface layer 34 is formed up to the same level as the upper end surface of the water collecting fitting 10, leaving the water collecting slit 15.

  The net 11 prevents the aggregate of the water-permeable pavement material 23 from dropping from the water collecting hole 8 on the upper surface of the cover plate 7 and clogging the water collecting passage 4 to reduce the drainage efficiency. It also serves to increase the bond strength between the asphalt and the cover plate 7. The size of the hole in the net may be any size as long as aggregates and asphalt do not pass through. Examples of the material used for the net include reinforcing fibers such as glass fibers, inorganic fibers such as carbon, fibers such as synthetic resins, and stainless steel.

  The gutter body 2 is supported by foundation concrete 35 in the ground and crushed stone 36 below it.

  According to the side gutter constructed according to the above procedure, the rainwater that has fallen on the permeable pavement surface layer 34 of the roadway 30 passes through the surface or the inside of the permeable pavement surface layer 34 along the transverse gradient, and the water collection of each cover plate 7. Through the hole 8, it flows down to the water collecting channel 4 inside the gutter body 2 and is collected. In addition, when there is rainfall exceeding the water permeability of the permeable pavement surface layer 34 such as during heavy rain, rainwater that has not permeated into the permeable pavement surface layer 34 is located near the curb 33 from the upper surface of the permeable pavement surface layer 34. All flows into the water collection slit 15, passes through the water collection hole 7, and is collected in the water collection channel 4.

  Rainwater that has not completely permeated into the permeable pavement surface layer 34 flows into the water collecting slit 15, so even if there is rainfall that exceeds the permeable capacity of the permeable pavement surface layer 34, rainwater accumulates on the roadway 30 and water enters the roadway. No pool is formed. Moreover, even if the water permeability of the water-permeable pavement surface layer 34 gradually decreases due to accumulation of dust, dust, sand, etc. for many years, the water collecting slit 15 serves to supplement the water-permeable ability of the water-permeable pavement surface layer 34.

  For example, when corrugated steel is used as a permanent formwork, the fall of the formwork plate in the wet space over a long period of time or the fall of the aggregate may interfere with drainage. Since the cover plate 7 made of concrete is used as a permanent mold, there is no problem due to corrosion of the mold plate. This is because the net 11 laid on the upper surface of the cover plate 7 during the laying and rolling operation of the water-permeable pavement material 23 is not corroded, and the aggregate falls into the side groove body 2 through the water collecting hole 8. , Does not interfere with water collection.

  FIG. 10 shows a second embodiment of the present invention, which is an example in which a pavement surface layer 37 having a low water permeability is constructed using a relatively dense grain pavement material. The same members or components as the components or components shown in FIG.

  Compared with the water collecting metal fitting 10 of the first embodiment, the water collecting metal fitting 40 in the present embodiment has an L-shaped metal fitting body 41 and an L-shaped auxiliary body arranged in parallel with each other at a wider distance L. The pieces 42 are connected to each other by a connecting portion 43, and in the inner space S formed by the metal fitting main body 41 and the auxiliary piece 42, a metal having a width of 100 mm having a large number of water collecting slits 44 partitioned in a lattice shape. The water collecting frame 45 is housed and arranged. On the inner surfaces of the metal fitting main body 41 and the auxiliary piece 42, a support piece 46 that supports the water collecting frame body 45 is projected.

  In the construction of this embodiment, the metal fitting body 41 and the auxiliary piece 42 of the water collecting metal fitting 40 are attached to the upper surface of the cover plate 7 as shown in FIG. That is, the dedicated bolts 18 are respectively attached to the bolt holes (not shown) at both ends of the mounting portion 46 of the metal fitting body 41 and the bolt holes (not shown) at both ends of the mounting portion 47 of the auxiliary piece 42 from above. In the state where the left and right horizontal locking portions (not shown) at the lower end of each dedicated bolt 18 protruding through the hole 8 are rotated 90 degrees and locked to the lower surface of the lid plate 7. Then, the nut 22 at the upper end of the dedicated bolt 18 is tightened, and thereby the water collecting metal fitting 40 is fixed to the upper surface of the cover plate 7.

  Next, the water collecting frame body 45 is accommodated in the inner space S formed by the metal fitting body 41 and the auxiliary piece 42 of the water collecting metal fitting 40. In a state where the water collecting frame body 45 is housed and arranged in the inner space S, each water collecting slit 44 of the water collecting frame body 45 communicates with the water collecting passage 4 through the water collecting hole 8 of the cover plate 7.

  Next, the reinforcing fiber net 11 is laid on the upper surface of the cover plate 7 excluding the water collecting metal fitting 40 so as to cover the water collecting holes 8, and the water-permeable pavement surface layer 37 continuing from the upper surface of the roadbed 31 is formed thereon. The upper surface of the cover plate 7 excluding the water collecting frame 45 is constructed to the same height as the upper end surface of the water collecting metal fitting 40.

  In places such as cold districts, aggregates having a high particle size may be used as the pavement surface layer material. In this embodiment, a collection of water collecting slits 44 having a plurality of rows of water collecting slits 44 in the width direction and the length direction is formed in a lattice shape. By using the water frame 35, it is possible to collect all rainwater flowing on the upper surface of the pavement surface layer 37 from each water collecting slit 44 into the water collecting channel 4 of the gutter body 2.

  The water collecting frame 45 is formed in a lattice shape and has strength, and can secure sufficient strength even when a large vehicle passes as a part of the roadway, and the width of each water collecting slit 44 is 9 mm or less. So, passers-by won't pinch shoe heels.

  The embodiment described above is an example in which a pavement surface layer is newly provided on the roadbed 31 after removing the existing pavement surface layer 32 on the roadbed 31 adjacent to the existing gutter body 2, but the existing pavement surface layer is left as it is. The pavement surface layer may be newly provided from the top of the existing pavement surface layer 32 to the entire upper surface of the new cover plate 7 around the water collecting slit 44.

  The side groove construction method according to the present invention can be used as a side groove construction method having water collecting performance that can be constructed for a short period of time and at low cost by using an existing side groove main body as it is.
