Description

[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable slope type gutter product laid continuously on a side edge of a road and provided with a bottom wall slab inverted concrete in which a desired flow gradient is joined and a method for producing the same. Things.
[0002]
2. Description of the Related Art A conventional general road gutter is constructed by laying a series of U-shaped cross-groove products composed of left and right side wall plates and a bottom wall plate. Since the distance between the top of the wall slab and the top of the side wall slab, that is, the groove depth, is constant over the entire length of the gutter product, the waterway bottom gradient must be the same as the gutter top and the road longitudinal gradient. As a result, the speed of the water flow in the waterway cannot be accelerated, and contaminants such as sand, mud, and garbage settle and accumulate on the bottom of the waterway, which tends to cause poor drainage.
[0003]
The proposed free-slope gutter, which can be constructed easily and freely regardless of the vertical gradient of the road, has a horizontal bearing beam section integrally formed between the upper ends of the left and right side walls, and a lower part between the left and right side walls. Is a fully open bottom, the left and right side wall slabs are placed on the foundation ground at the bottom of the excavation groove at the side of the road, and invert concrete is poured into the fully open bottom according to the waterway gradient (for example, see Patent Document 1). ).
[0004]
In another slope-free gutter product, a horizontal load-bearing beam is integrally formed between the upper middle part of the left and right side wall plates, the lower part between the left and right side wall plates is fully open bottom, and the foundation is cast at the bottom of the excavation groove on the road side edge. Left and right side wall slabs are placed on concrete, and invert concrete is poured in accordance with the gradient of the water channel on the foundation concrete that has appeared at the open bottom of the entire surface (for example, see Patent Document 2).
[0005]
However, in both the gutter product of Patent Literature 1 that pours invert concrete on the foundation ground and the gutter product of Patent Literature 2 that pours invert concrete on the foundation concrete, the front of the lower inner side surface of the left and right side wall plates is not used. If the treatment is not properly performed, the left and right side wall slabs and the invert concrete are not tightly integrated, and in practice, both may be cut off in all or part of the length direction. In this case, the four sides of the upper, lower, left and right sides did not form a box-shaped cross-section, but the rabbit seemed to be a corner and was structurally vulnerable.
[0006]
In still another gutter product, a horizontal bearing beam portion is integrally formed between the upper ends of the left and right sidewall plates, the lower portion between the left and right sidewall plates is a fully open bottom, and a reinforcing member is connected between the lower inner surfaces of the left and right sidewall plates. The left and right side wall slabs are placed on the foundation concrete cast at the bottom of the excavation groove at the side edge of the road, and the bottom concrete is cast on the foundation concrete appearing at the full open bottom in accordance with the water channel gradient, and Is wrapped in the bottom concrete (for example, see Patent Document 3).
[0007]
In the gutter product of Patent Literature 3, since the bottom concrete and the left and right side wall slabs are tightly connected via the reinforcing bar member, in a section having a horizontal load-bearing beam portion, a box in which the four sides of the upper, lower, left, and right parts are interconnected. It becomes a cross section and is structurally strengthened, but when it is necessary to replace and repair a part of the gutter line after an earthquake or a landslide, etc., adjacent gutter products are mutually connected by bottom concrete that is continuously cast. Because they are integrated, it is very difficult to take out and replace only the gutter product to be repaired, requiring a lot of labor.
[0008]
In addition, conventional gutter products are molded by placing the bottom wall slab on the upper side in consideration of workability and fluidity when pouring concrete material into the formwork, curing it as it is, and shipping it. Have been. Therefore, the gutter products unloaded from the carrier of the hauling truck to the laying site need to be inverted so that the bottom wall slab is on the lower side as a preparatory work before placing and installing it on the foundation ground or foundation concrete, Dedicated reversing machines need to be brought in and installed at the laying site, and the laying site requires plane space for the reversing machines and skilled operators to be deployed, which increases the impact area of traffic obstacles and increases laying costs. Has been brought.
[0009]
After installing the gutter product, a lid plate is hung on the top opening of the gutter main body.However, since no mechanical force can be used for this lid plate hanging operation, an operator must remove a heavier lid plate. It must be transported sheet by sheet, and the posture must be controlled so that the concrete does not chip into the cover plate or gutter main body, and it must be carefully fitted into the specified position. It became longer.
[0010]
After the cover plate is loaded into the gutter main body, the earth and sand is buried in the outer space of the left and right side wall plates. At this time, the backfilled earth and sand is filled from the gap between the lid shoulder on the inner surface of the side wall plate and the end surface of the cover plate. In order not to invade the inside, a gap covering tape is stuck over the top of the side wall plate and the cover plate.
However, taping a long laid gutter line and peeling off the tape after backfilling requires considerable material and labor costs, which also hinders savings in laying costs.
[0011]
In addition, it is not easy to accurately cast invert concrete from the open top of the gutter body to the planned channel bottom slope at the installation site where the working environment is not good. May be formed.
In addition, since concrete is cast on site in the open-air, the work must be postponed in rainy weather, which adversely affects the water-to-cement ratio of the concrete, and the cast-in bottom concrete must be cured and hardened as necessary. After that, since the next laying process is started, the entire laying period must be long, and the period of traffic regulation is to be lengthened accordingly.

It has been cast.
[0017]
DESCRIPTION OF THE PREFERRED EMBODIMENTS In producing a gutter product according to the present invention, a molding apparatus of a cast molding system or an immediate demolding system installed in a general concrete secondary product production plant is appropriately used. . The side groove main body 10 composed of the left and right side wall slabs 11, 11 and the bottom wall slab 12 is integrally formed by filling a forming mold loaded in a forming apparatus with a cement concrete material having required fluidity.
In consideration of the filling property of the concrete material, the forming frame of the gutter main body is arranged so that the bottom wall slab is located on the upper side, and after the filled concrete has set and hardened to a predetermined value, the forming mold of the gutter main body is formed. The frame is turned upside down using the reversing mechanism of the forming device so that the bottom wall slab is on the lower side as shown in FIG.
[0018]
The formwork portion contacting the upper surface of the bottom wall slab 12 and the formwork portion contacting the roots of the left and right side slabs 11 and 11 are removed from the forming mold of the gutter main body 10, and the inverted concrete 14 is removed from the bottom wall slab. The space surrounded by the upper surface of the base 12 and the bases of the left and right side wall plates 11 and 11 is filled. At this time, as shown in FIG. 3, in order to form a required flow gradient by the upper surface of the invert concrete 14, the forming mold of the gutter main body has an angle corresponding to the planned flow gradient with respect to the horizontal plane. It is held inclined with respect to the horizontal plane. After the filled invert concrete 14 has set and hardened to a predetermined value, the molding form of the gutter main body is returned to the original upright posture.
[0019]
The mold portions that contact the inner surfaces of the distal end portions of the left and right side wall plates 11, 11 are removed by an amount corresponding to the molding thickness of the cover plate 13, and the cover plate forming mold is replaced with a mold for forming the side groove main body via an appropriate support member. Attached to the frame. As shown in FIG. 4, a reinforcing bar assembly 19 is provided in the molding space of the cover plate. A concrete material for forming a cover plate is filled so as to surround the reinforcing bar assembly 19, and the cover plate 13 and the left and right side wall plates 11, 11 are integrally formed. In order to increase the structural mechanical strength, it is desirable that the reinforcing member of the cover plate and the reinforcing member of the side wall plate are interconnected or intersected and wrapped in concrete.
[0020]
The gutter product provided with the invert concrete 14 and the cover plate 13 is transported to the curing yard, and when the concrete of each part has set and hardened to a predetermined value, the gutter product is removed from the molding form and the attached formwork of the gutter body. It is removed from the mold and stored until shipment, with the bottom wall plate 13 arranged on the lower side and the lid plate 13 arranged on the upper side in an upright state.
It is transported to the laying site of the gutter in the above-mentioned upright posture, and is suspended by the heavy machinery on the foundation ground 16 or the foundation concrete 17 compacted at the bottom of the excavation trench 15. Usually, a fixed sealing material 20 for waterproofing is attached to the joining end face of the gutter product at the factory stage, and the fixed sealing material is compressed between the joining end faces of the adjacent gutter products via an appropriate connection fitting.
