Abstract

PURPOSE:To form a sewer culvert or the like in multiple layers and further enable the free adjustment of its gradient by mounting a wall unit to the lower of a side wall internal surface for forming a step, and building inverted arch- provided bodies in a floor board and the step, respectively, while charging them with mortar. CONSTITUTION:Side walls 1, 1 are, respectively, provided with stepped parts 2 on their upper part internal surfaces, where a flat cover 4 consisting of opening parts and a non-opening part is fixed. Further, the side walls 1, 1 are provided, at their internal surface lower parts, juxtaposed hollowed with internal thread holes 5 which specify 1/3 the thickness of each side wall 1. Then wall units 6, 6 forming a step 9 are mounted by blots 8. Subsequently, inverted arch- provided bodies 12, 12 are, respectively, built in a floor board 16 and the step 9 before being charged with mortar, and integrally formed with the side walls 1, 1, and thus a culvert of two upper and lower layers is formed. By giving a change to thickness of the mortar, a gradient of each culvert is freely changed for the side walls 1, 1 in the advancing direction of their top part surfaces.

Description

[Detailed Description of the Invention] ＼ (Industrial Field of Application) This invention enables the construction of various slopes within the main body by freely setting each slope in a place where the installation slope cannot be set when flowing water through the divided main body. It relates to a flock that can be freely sloped into a multilayered structure that can incorporate stored items.

(Prior technology) Conventionally, in order to remove surface water, an L-type trench was laid on the side of the road to take in surface water, while a U-shaped trench was constructed on the side of the road to take in surface water. Rainwater and domestic wastewater are collected separately as separate streams, or they are taken in as a combined stream.Also, even if they are combined, a single combined pipe is buried underground and gray water is collected from each building through water pipes. In the case of diversions, two buried pipes, a rainwater pipe and a sewage pipe, are buried underground to take in surface water and gray water that becomes sewage and drain it to the pumping station.In addition, in small and medium-sized rivers and irrigation canals, , both the irrigation water and small and medium-sized rivers are in one ditch, and the water volume is controlled by digging down the river bed and making the river wider, and the land area is widened.''The second part is the open river and irrigation canal. There are many.

(Problems to be solved by the present invention) Therefore, in the combined type and the separated type, the installation cost is high and the construction period is long, resulting in traffic congestion and large inconvenience to nearby residents due to construction noise and construction regulations. In the combined system, the rainwater and sewage merge and are removed, and the diameter of the pipe becomes larger, and the pipe diameter is larger, At the confluence, there is a foul smell of sewage, and when it rains, when the raindrops cross the fixed point, the sewage also floods, and sewage pipes are laid between the outflow pipe and the sewage pipe. By burying 11.1 water pipes in the same road, road surface repairs and construction may cause obstructions to traffic, and during rain, rainwater may leak onto the road surface. In order to compensate for defects such as ground subsidence caused by falling pressure and vibrations, we installed integrated structures of the diverting type on the roadside strips and in the center of the road to improve the appearance of landscaping. Should the sewage be drained separately? If the gravity flow method is used on the rainwater side because it is a body structure, the slope of the sewage side cannot be maintained, and the minimum return flow velocity cannot be obtained, resulting in stagnation of sewage. If the pipe is laid on the slope on the sewage side, it will become a rainwater slope or a steep slope. However, in terms of construction unit cost, rainwater and sewage are laid separately and become double pipes, which lengthens the construction period and leads to an increase in the number of construction works.1. When irrigation canals are constructed with a slope, the river bed has to be dug down, which increases the depth and makes it even more layered, so the current situation is that the river area is not utilized effectively.

(Problems to be Solved by the Present Invention) The objectives of the present invention are to shorten the installation work in construction, reduce the unit cost of construction, and improve the flow rate of the same amount of flowing water taken into a multi-layered flock with a free slope. The slope and the slope within the main body can be freely set in opposite directions and l-, the slope of irrigation canals and small and medium-sized rivers can be freely set, and the site area of some opening areas in irrigation canals and rivers can be adjusted freely. It provides effective utilization.

(Function) A block with a free slope is laid at the rear of the excavation after removing the existing structure laid in the roadside strip or center of the roadway, or an excavation trench is dug in the roadside strip or center at a new construction site. , a hook 17 with a free slope is laid therein. Then, after pouring concrete on the bottom, place the partitions, lids, and invert-equipped frameworks, cover most of the parts, and connect them. By doing so, you can create a drainage system with a free slope.・There is a method in which a lid is placed on a partition with an invert frame laid down, and concrete is poured on top of the lid of the partition to create a slope, and a method in which concrete is poured on the bottom and the partition to create both slopes. To create a slope by pouring concrete on the partition, turn the side with the invert of the frame with the invert toward the bottom, and pour concrete on top of it to create a slope. By installing it in irrigation canals and small and medium-sized rivers, you can freely set the gradient of the flowing water by combining surface water, gray water, river water, surface water and stored items, stored items with gray water, stored items with river water, etc. It is used to remove running water and store stored items.
