Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an undulating weir made of a flexible membrane, and more particularly to an undulating weir made of a flexible membrane whose covering attachment portion (covering clamp portion) is protected.

In the case of a flexible membrane undulating weir, a flexible membrane envelope (bag-like body), for example made of rubberized cloth, forming the weir body is attached to at least the river bed in the direction across the river, and the interior of the envelope is communicated with. Air, water, or other fluid is sent from the inlet/exhaust (water) pipe to expand and erect it, or discharge fluid from the inside of the envelope to cause it to collapse (for example, Japanese Patent Publication No. 11702/1970, Japanese Patent Publication No. 11702/1973).
(See No. 71).

In this type of undulating weir, in order to prevent the envelope from being damaged by boulders, etc. that flow down with the flowing water when the weir collapses (the boulders move on the envelope and damage the envelope), cushioning material is placed on the inner bottom of the envelope and It may be placed on the inner surface of the envelope.

FIG. 1 shows an example of a flexible membrane undulating weir equipped with this buffer material.

In the figure, 1 is a flexible membrane envelope, for example a rubberized cloth envelope, 2 is a river bed, 3 and 3' are cushioning materials, such as foamed polyethylene resin, 4,
4' is a bag for storing cushioning material, such as a rubber-coated cloth bag, 5 is an inlet/exhaust (water) pipe, 6 is a soil flow, 1 is a covering clamp part, and 8 is a small seal sheet.

An undulating weir with such a cushioning material can prevent damage to the weir envelope due to epidemics, etc., but it cannot prevent damage to the weir envelope clamp portion.

The present invention has been studied in view of the above, and provides a protection means in the clamp portion of the envelope.

The present invention will be described in detail below with reference to illustrative drawings, but the present invention is not limited thereto.

FIG. 2 is an enlarged view of the undulating weir made of a flexible membrane according to the present invention, taken along the river flow direction near the envelope clamp part (however, the upstream clamp part).

In Figure 2, 2 is a riverbed, 3 is a cushioning material such as foamed polyethylene, 4 is a bag for storing the cushioning material, such as rubberized cloth, 7 is a covering clamp part, and 8 is a sealing sheet. This is the same as described above.

The above-mentioned covering clamping part is similar to the means already well known from, for example, Japanese Patent Publication No. 44 2371, in which 11 is the main carpet or covering film, 12 is a cover sheet, 13 is a clamping bar 14 is a rod, and 15 is a tube. , 16 is a bar, 11 is a bolt, 18 is a sleeve,
19 is the anchor 20 is the nut, 21 is the base plate,
22 and 23 are drive screws. 28 is an epoxy resin.

The above is the same as before.

However, in the present invention, in order to protect the enveloping clamp part 1 from boulders etc., a cushioning material 25, for example, a foamed polyethylene material is used as the riverbed reference surface 3 where the clamp part 7 is located.
It is provided in an outer envelope recess 26 that is concave from 6.

Reference numeral 24 denotes a filler such as cuttings of a cushioning material, 21 a cloth-like member for fixing the cushioning material, such as a rubber-coated cloth, 28 a protective cloth-like member such as a rubber-coated cloth, and 29 an upward extension of the base plate 21 on the side opposite to the covering. 30 is a nut for attaching the cloth-like body for fixing the cushioning material planted therein, 31 is a seat plate attached to the upward extension part of Pol N7 for the covering clamp for attaching the cloth-like body for fixing the cushioning material, 32 is a nut applied to the upward extension of port 11, 33
Reference numeral 34 indicates a belt for fastening the cushioning material, 34 indicates a bolt, and 35 indicates a nut.

That is, as is clear from FIG. 2, the bolts 29, nuts 30, and bolts 11 are arranged so as to match the shape of the recess 26 in which the cushioning material 25 is wrapped with the cloth-like body 27 so as to cover the covering clamp part 1. Using Pol N7.2 seat plates 31. Natsuto 32
It is attached with.

At this time, a protective cloth-like body 28 is provided on the upper surface with both ends bent.

Note that the buffer material 3, the buffer material 25, and the reference plane 36 of the riverbed 2 are formed so as to be substantially on the same plane.

The cushioning material 25 is wrapped with the cushioning material fixing cloth body 27 as shown in FIG. 3, for example.

Figure a is a plan view, Figure C is a view taken along arrow A-A in Figure a, Figure C is Figure a.
Figure d is a view taken along line C-C in figure a.

In the figure, the same reference numerals as in FIG. 2 indicate the same parts.

As is clear from these figures, the tip of the cushioning material fixing cloth 27 that wraps around the cushioning material 25 (see FIG. 2) and meets on the upper left surface has bag portions 37 inserted alternately (see especially FIGS. c and d). A fastening belt is passed through this bag portion, and the vicinity of both longitudinal ends of the belt are integrated with bolts and nuts 34 and 35 (see Fig. 1).

Although the above-mentioned Fig. 2 describes the upstream side clamp section, the same applies to the downstream side clamp section. (However, it is not necessary to provide a weir as it is protected by the cushioning material on the inner bottom of the envelope and the inner surface of the envelope.)

According to the present invention as described above, since the clamp part is covered with a cushioning material, the clamp part is not damaged by rolling stones.
