Abstract

Disclosed is a steel surface stone dam used for water conservancy project. In a river reach of a canyon, a dam body is made of stones that are exploded and fell off, an upstream slope is closed to prevent the leakage with a steel plate. The utility model is composed of an anti-seepage steel plate, an extension ridge and an embedded part. A plurality of extension ridges are arranged on the surface of the anti-seepage steel plate; a draft tube is connected with the anti-seepage steel plate.

Description

Steel face stone dam

The utility model relates to a kind of device of dam, especially utilizes the stone that falls after the controlled blasting of mountain peak, both sides to work as dam body, and with the steel face dam of steel plate antiseepage.

On 99 years 15 33 phases of volume " Gazette of Patent for Invention ", the ice masonry dam is disclosed, the method that dam body leaks with artificial freezing technology sealing, this technological investment is big, and the construction period is long.

The purpose of this utility model provides a kind of steel face stone dam, and it is improved on the basis of ice masonry dam.It not only is suitable for the section, valley about 70 degree, needs only the stone aboundresources less than 70 degree, still can use by mechanical handing.

The purpose of this utility model is achieved in that the upstream batter steel plate is connected by the tension nail with the mountain rock with both sides grade beam fillet grade beam.The flexible ridge, several roads is established in the centre, and mozzle is connected with barrier sheet.When after the earthquake during generation sedimentation of stone dam, the flexible ridge is drawn back voluntarily.Adopt controlled blasting in batches to prevent to bring out earthquake.The thickness that strengthens dam body remedies stable deficiency and the attack that tackles guided missile in the local war.The bottom surface angle is by thrust transformation power at the bottom of dwindling dam body both sides and river.The corrosion resistant plate antiseepage is laid on the surface.The girder steel of the corresponding rigidity of temporary laid solves the rehandling problem of main equipment on the bridge of necessary process.

Owing to adopt such scheme, be applicable to various geological structures, outside all antiseepage, intensity and the stable the utility model in conventional hydropower station use concrete dam can both possess, construction was simple, instant effect.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is a plane of the present utility model principle schematic.

Fig. 2 is a steel face dam profile.

Fig. 3 is a plan view.

Fig. 4 is the waterproof steel plate constructional drawing.

Among Fig. 1: 1, mountain peak, 2, waterproof steel plate, 3, the stone dam.Among Fig. 2: 2, antiseepage steel plate, 3, the stone dam, 4, mozzle, 5, grade beam.Among Fig. 3: 1, mountain peak, 2, the antiseepage steel plate, 3, the stone dam, 4, mozzle, 6, the border district beam, 7, derivation conduit.Among Fig. 4: 2, antiseepage steel plate, 4, mozzle, 5, grade beam, 6, the border district beam, 7, derivation conduit, 8, the flexible ridge (section), 9, tension nail (setscrew).Among Fig. 5: 1, Shan Yan, 2, barrier sheet, 3, the stone dam, 6, the border district beam, 9, tension nail (setscrew), 10, give and bury iron.Among Fig. 6: 2, antiseepage steel plate, 3, the stone dam, 5, end grade beam, 11, give and bury iron, 12, the riverbed rock, 13, positive negative zero.

In Fig. 2, the mountain peak, both sides if with the water surface discrepancy in elevation about 500 meters, after mozzle is installed on the dam site, promptly carry out explosion, after height of dam reaches designing requirement, begin to construct from top to bottom from the top.The rear enclosed bottom of damming, upstream in dry season.

So far shown and introduced a kind of steel face stone dam that those skilled in the art are with reference to implementing.

Claims

1, a kind of steel face stone dam, antiseepage steel plate, the flexible ridge, give embedded part, border district beam, tension nail and connect, it is characterized in that: the antiseepage surface of steel plate is established the flexible ridge, several roads, mozzle is connected with barrier sheet, the border district beam with give embedded part and be connected, the limit is given embedded part and is connected with the tension nail, and antiseepage steel plate in bottom gives embedded part the end of with and is connected, and give embedded part and is connected with end grade beam at the end.
