Description

[Detailed Description of the Invention] In particular, the present invention relates to a joint structure of a water conservancy structure having a U-shaped cross section forming a drainage ditch.

When constructing drainage ditches by joining together a number of irrigation structures with a U-shaped cross section formed by bending steel plates,
Curved collection according to the topography of the site.

Drains are often required. For example, the collection drainage ditch 02 shown in Figure 2 is formed by joining together a plurality of steel plate irrigation structures 01 with a U-shaped cross section as shown in Figure 1. 02 meanders in the horizontal plane. Similarly, the drainage ditch 03 formed by the water conservancy structure 01 is laid along the slope from the horizontal plane, so the upper,
It is curved at the bottom.

However, in the drainage ditch O2, some of the connections between the former water conservancy structures located at the curved parts are canted (melted and welded and connected to each other).

In the drainage ditch 03, the connection parts of the irrigation structures Qle and Olf are partially cut and welded to each other.

In this way, a steel plate irrigation structure was constructed on site.

Welding work is inefficient. O is a factor that increases construction costs. Also, a collection of steel plate irrigation structures 01 joined together.

When drains are installed on soft ground, changes in the ground (e.g. uneven settlement) can cause excessive force to be applied to the drains and drains. drainage ditches may be divided.

The present invention has been devised under such circumstances, and its purpose is to install. Construction is easy.

Irrigation structures that can easily follow changes in force and ground
The main feature is that it provides a 5J joint structure.

The configuration of the present invention is such that in a joint structure of an LJ-shaped irrigation structure, a disconnection circuit forming a collection or drainage ditch straddles the inner periphery or outer periphery of each opposing end of a pair of irrigation structures installed opposite each other. ,
Before installation σ) The cross-sectional shape is curved.This joint made of 9QJ 42 is watertightly fastened to each irrigation structure using the threaded paulownia.

In the non-invention, as mentioned above, the cut-off circuit has a U-shaped water conservancy 4.
The structure is connected to each other using a threaded part (2) with a curved cross-sectional shape (A made joint member), so when forming a collection of curved shapes and a drainage ditch, it is difficult to use water conservancy structures. There is no need to worry about processing the object itself into a vertical shape on site. 1. Work efficiency is improved, construction costs are lower, and the ground does not subside or rise.
There is also the advantage that the elastic material joint part easily deforms elastically even if there are fluctuations due to soil movement, etc., so that the irrigation structure can follow the fluctuations of the ground, and damage to drainage channels can be prevented.

An embodiment of the invention is shown in FIGS. 4 to 10 below. FIG. 4 shows a plurality of U-shaped steel plate irrigation structures 3,
A drain groove 2 formed by connecting with a rubber joint member 6 is shown installed on the ground 1.

Thus, the water conservancy structure 3 made of copper plate has undulations in the direction of water flow in the drainage ditch 2 (multiple lines θ that are the same in the direction along the plane perpendicular to the arrow A).

It is formed of a so-called corrugated plate (see Figs. 5 and 6. However, Fig. 5 is a view in the direction of the ■-■ line KjE in Fig. 4, and Fig. 6 is a view in the direction of the line KjE in Fig. 5. Vl # is a sectional view), the L-shaped members 4 are deep (fixed) along both open ends, and a pair of L-shaped members 4 are connected at the end opposite to the adjacent irrigation structure 3. Reinforcement frame (L-shaped side) 5/
(See FIGS. 5 and 7. However, FIG. 7 is a view taken along the line ■-■ in FIG. 4.)

Note that the corrugated plates 0) that form the irrigation structure 3 can be arbitrarily selected for the wave depth and pitch. Also good.

The rubber joint member 6 is a rain gutter-like member with a U-shaped disconnection, the length of which coincides with the outer circumference of the irrigation structure, and a pair of curved parts 7. σ) The flange part 8 and the outer end of the flange part 8; (if'+ls
A plurality of screw openings 8a are formed in the flange portion 8, and an outer surface 11 is formed in the rubber wall.
111 (the side from which the jaw portion 9 protrudes), the canvas 10 is inserted (inserted during vulcanization molding of the rubber layer main body) to strengthen it (see FIGS. 8 and 9).

FIG. 9 is a sectional view taken along the line ■--■ in FIG. 8).

Note that the protrusion amount H and the width '1° of the mg till Hll 7 can be arbitrarily selected. 1 for
Align the flange portion 8 of the joint member 6 along the outer wall surface 38 protruding at the opposite end of the inland water A/S structure 3 (see Fig. 10. However, Fig. 10 is similar to Fig. 7). (This is an enlarged cross-sectional view taken along the line X-X of FIG. 3, the joint member 6 can be firmly tightened. Note that the washer 11 may be inserted for each port 12, but the side wall of the irrigation structure 3. , the joint part 6 which connects the U-shaped curved part 7 in the hr plane to M-z
Even if the ground on which the drainage ditch 2 is installed changes due to subsidence, uplift, etc., the joint member 6 can freely expand and contract.

The valley irrigation structure 3 easily follows the fluctuations, and no damage to the water drainage structure 3 occurs. In addition, collection.

Adjacent irrigation structures 3 are connected to the platform on which the four-groove water groove 2 is laid in a straight line at intervals that can maintain the initial cross-sectional shape of the joint gutter 6 (cross-sectional shape before installation). Put it down.

The elasticity of the joint member 6 can be effectively utilized.

In addition, if the drainage ditch 2 is laid horizontally or curved in the vertical direction, the adjacent water in the curved part should be
One side wall of the structure q@3 is brought closer, and the other side wall is 1 lil L L from it, so on the side of the joint member 6.

It is contracted and attached on the other side in a state close to the initial cross-sectional shape. By lI+ < 3-, relative displacement of adjacent water conduits (1"q relics at the curved part is allowed).

Historically, even when installing drainage I (L# 2) in a curved shape, the joint member 6 is simply attached to the irrigation structure 3 without processing the irrigation structure 3 by cutting or other means. Since it is only tightened at [pol 1-12.Natsuto] 3,
Construction work efficiency is improved and cost reduction is achieved.

Furthermore, even if the amount of ground movement is large and a relatively large tensile force is applied to the joint member 6, the canvas 10
Since the flange portion 8 is inserted, the tension force can be sufficiently increased.

Bolt 12. Even if the nut 13 receives a force that causes the pressing part to come off, the jaw part 9 will engage with the washer.

Its departure is prevented.

Furthermore, since the joint member 6 is reinforced with the canvas 10, it can sufficiently withstand water pressure from the inside of the drainage ditch 2, or external pressure from earth and sand.

In addition, since the canvas lO is inserted biasedly toward the outer surface of the rubber wall, even if water containing soil and sand flows through the drainage ditch 2 and the inner wall side of the joint member 6 is worn out, the canvas lO There are no easily exposed parts, and the durability is good.

Furthermore, in the above embodiment, the handle part 6 is directed to the outer periphery of the irrigation structure 3, but a structure in which it is directed to the inner periphery may also be adopted. It is preferable that the curved portion of J- is made to protrude to the outside of the irrigation structure as in the above embodiment.
As a result, the cross section of the waterway is reduced and the flow is obstructed.

In place of the joint member 6, a joint member 16 having the shape shown in FIG. 11 may also be used. The same joint part month 16 is,
Each pair of jaws 19 is provided on both flange portions 18 . II.191), and which one of the grooves B and C defined by the jaws 19a and 19b? Select and insert the bolt.

Tighten. That is, when the initial cross-sectional shape of the joint member 16 does not change during installation, if the first groove B is tightened, the joint part (
The deformation of A16 -111- increases. It is convenient to use them depending on the curvature of the curved part of the drain and the joint part (A16).
“tj Just tighten it at the C part.

Furthermore, collection, drainage? 74 on a slope where there is a possibility that each irrigation structure may slip along the slope.

As shown in Fig. 12, both ends of the reinforcing frame 25 connecting the open end of the water conservancy 4'+4 structure 23 are extended, and the extensions are hardened with concrete R-25A, or as shown in Fig. 13. As shown in FIG. 14, a pile 25B is passed through and fixed to the extension, or alternatively, an adjacent water conservancy structure 23 is fixed as shown in FIG.

They are connected to each other by a chain 30. In this way, even if each irrigation structure moves along the slope, no unreasonable tension is applied to the joint member 26.
