Description

[Detailed Description of the Invention] The present invention relates to an apparatus for creating a waterway, and in particular, an apparatus for creating a waterway by pouring a lining material such as concrete onto the wall of an excavated trench.

To create a waterway, first, an excavated trench is excavated, and concrete is poured to a uniform thickness on the wall of the excavated trench as a water-blocking layer.

However, in order to pour concrete onto the walls of an excavated trench that will become a waterway, formwork is temporarily set up along the wall, concrete is poured between the formwork and the wall, and the formwork is removed after the concrete has hardened. There is.

As described above, pouring concrete to a uniform thickness on the wall surface of an excavated trench requires troublesome operations and a long time, and there are disadvantages in that creating a waterway is troublesome and inefficient.

The present invention was developed in view of the above circumstances, and its purpose is to make it possible to cast lining materials such as concrete on the walls of excavated trenches to a uniform thickness in a short period of time with simple operations, and to form waterways with simple operations. To provide a waterway creation device capable of efficiently creating a waterway.

Embodiments of the present invention will be described below with reference to the drawings.

In the drawing, 1 is a mold frame, 2 is a hopper provided at the front end of the mold frame 1, 3 _L and 3 _R are a pair of scraping screw conveyor mechanisms on the left and right, and 4 _L and 4 _R are a pair of left and right screw conveyors for pushing. It is a mechanism.

The mold frame 1 consists of a bottom plate 1a along the bottom wall _a1 of the excavated groove a, a pair of left and right inclined side plates 1b along both inclined walls _a2 and _a2 , and left and right sides along the left and right upper end surfaces _a3 and _a3 . The pair of collar plates 1c and 1c form a cross-sectional shape that is substantially the same as the cross-section of the excavated groove a.

The hopper 2 has a shape with an open bottom formed by the rear plate ₂₁ , the front plate ₂₂ , and a pair of left and right side plates ₂₃ , ₂₃ , and the center part of the rear plate ₂₁ has a concave portion 5 curved toward the rear end. In addition, mounting seats 6, 6 for attaching to the vehicle are integrally formed on the front plate ₂₂ .

Each raking screw conveyor mechanism _3L , _3R is capable of freely rotating a screw conveyor 8 between each side plate ₂₃ and a bracket 7 fixed at the lower center of the front plate, and is connected to an inclined wall _a2 of an excavated groove a. It has a structure in which the hydraulic motors 9 for driving are fixed to the side plates ₂₃ , respectively.

Extrusion screw conveyor mechanism 4 _L and 4 _R are the front plate 2
_Extrusion screw conveyors 10 are rotatably provided on both sides of each extrusion screw conveyor 1.

It has a structure with

In the embodiment, each extrusion screw conveyor 1
0 is provided tilting downward toward the rear, and each collar plate 1
A curved convex portion 12 is formed on each portion c, and the tip thereof is formed so as not to interfere with the collar plate 1c.

Reference numeral 13 designates a guide member that is fixed to the center of the front plate ₂₂ facing forward, and has a curved portion 13a that contacts both inclined walls a ₂ and a ₂ to guide the entire device to move smoothly. ing.

14 is a bent edge formed integrally with the collar plate 1c;
The concrete is regulated to prevent it from flowing to the sides.

The entire device is then mounted on a vehicle (not shown) via the mounting seat 6 and set in the excavated groove a.

In this state, when the vehicle is driven and the entire device is moved along the excavation groove a, concrete is poured into the hopper 2, falling downward and against the bottom wall of the excavation groove a.
a ₁ The deposited concrete is piled up in the center part, and the piled up concrete is scraped up toward both sides of the upper part by a pair of scraping conveyors 8 on the left and right.

The concrete scraped up on both sides of the upper part is transferred to the upper end surface _a3 and the collar plate 1c by the screw conveyor 10 for pushing.
is pushed between.

At the same time, by moving the mold frame 1, the bottom wall a ₁
Concrete is forced between the bottom plate 1a and the inclined walls a ₂ , a ₂ and the inclined side plates 1b, 1b.

This causes the concrete to become the bottom wall of excavation trench a.
A ₁ , both inclined walls a ₂ , a ₂ , and upper end faces a ₃ , a ₃ can be cast with uniform thickness and uniform density. A is the concrete layer.

In addition, since the concrete is scraped up on both sides by the scraping conveyors 8, 8, the hopper 2
There is no need to uniformly charge the liquid in the left and right direction.

Therefore, the operation of charging concrete into the hopper 2 becomes easy.

Since the present invention is configured as described above, the excavated groove a
A waterway can be created by simply placing lining material on the wall.

In addition, the lining material fed into the hopper 2 is scraped up on both sides by the pair of scraping conveyors _3L and _3R on the left and right, so there is no need to uniformly feed the lining material into the hopper 2. The material input operation becomes easy.
