Abstract
The utility model provides a corridor encircles drainage structure, corridor arch is provided with the drainage drilling, is provided with the sealing plug in the drainage drilling, is provided with first drainage tube in the sealing plug, and first drainage tube lower extreme is connected with the return bend, and the lower extreme of return bend is connected with the second drainage tube, and the second drainage tube passes through the pipe strap to be fixed on the corridor lateral wall, and the lower extreme of second drainage tube stretches into in the escape canal of corridor bottom. The utility model discloses effectively prevent that the corridor drainage from splashing, reduce humidity in the corridor, avoid the corridor wall to take place because of phenomenons such as the mould, corruption that long-time flowing water erodees arouse. The construction safety is ensured, and the construction quality is ensured.
Description
Technical Field
The utility model belongs to the technical field of hydraulic engineering, concretely relates to corridor top arch drainage structure.
Background
The roller compacted concrete dam body drain hole forming is used as a matching process of the dam building, and various mature methods are provided and have achieved certain success; the drilling of the drilling machine is the best choice with the highest effect and time-saving quality guarantee, and the position of the bottom of the hole has deviation due to the inclined drilling hole of the drilling machine; the top of the dam gallery is designed in an arch shape, so that the position of a water outlet hole of the gallery arch is inevitably disordered by the drilling process, and the water seepage of the dam flows down along the drainage hole to change the gallery into a 'water curtain hole'; if drainage is not carried out, illumination and other electrical equipment in the corridor can be wetted for a long time, so that the work of engineering inspection personnel is inconvenient, and safety accidents are easy to happen; the green moss and erosion phenomena occur on the side wall of the gallery caused by long-term clear drainage, and meanwhile, the color of the flowing water range is obviously different from that of other parts, so that the appearance quality is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technology lie in overcoming the shortcoming of current corridor top drainage, provide a drainage structure is encircleed on corridor top that reasonable in design, construction are simple, the practicality is strong, improve the corridor life-span.
The technical scheme for solving the technical problems is as follows: the utility model provides a corridor top encircles drainage structure, corridor top arch is provided with the drainage drilling, is provided with the sealing plug in the drainage drilling, is provided with first drainage tube in the sealing plug, and first drainage tube lower extreme is connected with the return bend, and the lower extreme of return bend is connected with the second drainage tube, and the second drainage tube passes through the pipe strap to be fixed on the corridor lateral wall, and the lower extreme of second drainage tube stretches into in the escape canal of corridor bottom.
As a preferred technical scheme, the sealing plug is a rubber plug.
As a preferable technical scheme, the upper end of the first drainage tube is exposed out of the sealing plug by 10-20 cm.
The utility model has the advantages as follows:
the utility model discloses an elasticity rubber buffer shutoff drainage drilling for dam body drainage downthehole ponding discharges into the bottom drainage ditch through first drainage tube, return bend, second drainage tube, the corridor drainage is changed into the hidden row by conventional in the same direction as the bright row of wall, prevents effectively that the corridor drainage from splashing, reduces humidity in the corridor, avoids the corridor wall to wash out phenomenons such as the moldy, corruption that arouse because of long-time flowing water and takes place. The construction safety is ensured, and the construction quality is ensured.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, but the present invention is not limited to the following embodiments.
In fig. 1, the gallery top arch drainage and drainage structure of the embodiment is formed by connecting a first drainage tube 1, a sealing plug 2, a bent tube 3, a second drainage tube 4 and a tube clamp 5, a drainage drill hole is drilled in the gallery top arch, the sealing plug 2 is plugged in the drainage drill hole, the sealing plug 2 is a rubber plug, the first drainage tube 1 is inserted in the sealing plug 2, the upper end of the first drainage tube 1 is exposed out of the sealing plug by 210-20 cm, the bent tube 3 is connected to the lower end of the first drainage tube 1, the lower end of the bent tube 3 is connected with the second drainage tube 4, the second drainage tube 4 is fixed on the side wall of the gallery through the tube clamp 5, and the lower end of the second drainage tube 4 extends into a drainage ditch at the bottom of the gallery.
When the drainage device is installed, the sealing plug 2 is completely plugged into the drainage hole under the action of external force extrusion, so that the wall of the drainage drill hole is completely combined with the sealing plug 2; in order to further ensure the sealing performance, when the sealing plug 2 is installed, a little dry cement is added in advance, and after the drain hole is closed, the accumulated water is mixed with the cement to strengthen the sealing performance; make the downthehole ponding of dam body drainage and discharge into the bottom escape canal through first drainage tube 1, return bend 3, second drainage tube 4, the corridor drainage is changed into the secret row by conventional along the wall bright row, prevents effectively that the corridor drainage from splashing, reduces humidity in the corridor, avoids the corridor wall to wash phenomenons such as the moldy, corruption that arouse because of flowing water for a long time and take place, has guaranteed construction safety, has guaranteed construction quality.
