Abstract

<P>PROBLEM TO BE SOLVED: To provide a safe slit structure having high drain capability and capable of preventing occurrence of play, preventing a heel of high-heeled shoes from dropping, and preventing injection onto a road surface from a slit even in cleaning of the inside of a side ditch by high pressure water in the road side ditch with the upper face slit of various types. <P>SOLUTION: A drop lid side ditch is provided with a plurality of haunches along an inner wall from corner angles in a lid hooking part of a side ditch main body, keeps a fixed condition on a bottom face and at both corners of the bottom face while stored with play when setting a lid, and is put by preventing play. A portal free gradient side ditch is provided with an opening hooking a lid on an upper face and both sides between fixed boards by engaging cuts provided on the left and right on both sides of the lid with haunches on the left and right of both side upper fringe faces in the opening, is fixed on a bottom face and at four corners while stored with play when setting the lid, and is put by preventing play. The side ditch has a structure in which water drops and is drained like a crank through an intermediate step at a shallow position of a lip part in any of slit on an upper face, a slit in a continuous condition, and a continuous slit. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention belongs to the technical field of slit-type side grooves made of precast concrete continuously embedded in a road, and more specifically, the side groove top surface is prevented regardless of whether or not the side groove lid is rattled and the side cover is not rattled. It is related with the safety improvement of the drainage outlet slit part.

The lid side groove that has been used in the past is a drop lid side groove that sets the lid on the top of the U-shaped groove, and has a cross-sectional gate type with fixed plates at both ends of the top surface, and sets the lid at the opening on the top surface, There is a free-gradient side groove that forms the bottom as appropriate with the entire surface open, and since both have lids set on the top surface, rattling noise and corner breakage are likely to occur during vehicle travel, and as a countermeasure against rattling More and more, a method of interposing a cushioning material such as a gourd material in a fitting portion between the side groove main body and the lid, and a shape of the fitting portion between the side groove main body and the lid are often devised.
Recently, a side groove body with an opening formed so that the lid is set to the same width and the same width as the fixed plate is used. After installing the side groove body, concrete is poured from the opening on the upper surface to freely form an arbitrary drainage gradient. After that, a method has been proposed in which a lid is set to form an integral structure, and the lid is pressed from both sides by an asphalt layer or a roadbed material to prevent rattling.

  The surface drainage of the road surface water is generally formed with a 1.5-5cm wide slit at the top of the side groove, so the pedestrian's line of sight reaches the bottom of the side groove and feels dangerous, and even high heels This is a weak point in safety, and is a common weakness even in the side groove of the top plate integrated type that has no lid and does not rattle.

As a measure for improving the safety of the drainage outlet on the side groove upper surface, in recent examples, the road surface drainage function is limited, and the width of the slit is reduced to, for example, 1 cm or less to make it difficult for pedestrians to enter high heels.

  However, when rubber material or the like is interposed between the conventional side groove body and the lid with respect to rattling, the left and right play remains even if the bottom of the lid can be crimped, and the side groove body in the case where the shape of the fitting part is devised Since the lid is a special specification product, it is difficult to supply in general, and the lid side groove is not preferable in terms of removing and maintaining the lid. In addition, in a portal-shaped free-gradient side groove whose upper surface is fixed and both ends are fixed, the top ends of both side walls of the opening are exposed with a thin thickness after the lid is set, and only this part is exposed due to wear during vehicle travel. It is easy to damage and is a weak point,

  In addition, even if the lid covers only the both sides of the side groove, the weak point of the opening can be removed, but the lid is rarely fixed with asphalt layer or roadbed material on both sides, causing rattling and vehicle It is not sufficient to prevent noise and corners during driving.

  For the drain slit, a blind is necessary to prevent the pedestrian's line of sight from reaching the bottom of the side groove. On the other hand, for safety reasons, reducing the width reduces the falling drainage of the road surface water and covers the lid. Regardless of the presence or absence, the function of the road gutter is impaired.

  The present invention solves the problems in the prior art as described above, and in the lid side groove, an oblique rib that rubs in the middle of the height from the corner of both lids to the side groove body for setting the lid on the inner wall. Openings are provided at multiple locations on one side of the lid at two or more locations, and in the free-gradient side groove, the lid is placed and housed on both sides with hunches on the left and right with the same width as the two fixed plates After installing the gutter body, put the concrete through the opening on the top surface to form the bottom part as appropriate, and then engage the right and left hunches on both sides of the gutter body with lids with cuts on both sides And set.

  And the slit of a drain outlet is formed in a crank shape toward the downward direction, and an intermediate step is provided at a relatively shallow position from the upper surface, for example, a depth of 1.5 to 3 cm.

  Furthermore, if necessary, a filter is incorporated into the slit mouth portion on the intermediate step to maintain the function of dropping and draining road water while the slit is closed.

  Even when the lid is used, there is no backlash, and a road side groove with a slit on the upper surface can be obtained easily and inexpensively in common with the integrated type without the lid.

  In addition to the fact that the pedestrian's line of sight does not reach the inner bottom of the side groove due to the intermediate step, the danger of the road surface is removed, and the intermediate step is also slit against depression of wheelchairs, tricycles, high heels, etc. The safety is improved without lowering the drainage function of the road surface.

  In addition, if a filter such as permeable concrete, permeable resin concrete, or permeable asphalt is installed in the slit, if necessary, the periphery is fixed with a discharge port secured on one side on the shallow intermediate step. The thickness of the filter is limited to the inside of the slit mouth, and the water permeability function is maintained without being excessive.

In order to prevent rattling of the lid, first, in the falling lid side groove where the lid is set continuously, the left and right sides of the lid are stored with the necessary play on the inner wall of the side groove body, and at the same time the bottom surface Each rib-shaped haunch is held as a whole even if it has strength, and both corners are placed in a fixed state together with the support at the bottom contact portion.
Also, in the free-gradient side groove that sets the lid in the middle of both fixed plates, the front and rear fixed plates and the lid are stored with the necessary play, and at the same time the left and right cuts on both sides of the lid engage with the left and right hunches on both sides of the main body. It is held and placed in a fixed state together with the support at the bottom contact portion.

  And the top of the culvert side groove that combines the lid on the lid side groove, the drain connection slit on the lid and lid, the integrated side groove without the lid, and the inverted U-shaped lid with the U-shaped groove The drain slit provided in the plate is formed in a crank shape with an intermediate step provided in a relatively shallow portion from the upper surface facing downward.
