Problems solved by technology

Among the above-mentioned methods, water-side seepage interception or reverse filtration seepage diversion ditch is an effective means to prevent embankment failure, but it cannot prevent the occurrence of overflow, while the construction efficiency of traditional measures to increase the height of the dam crest to prevent overflow is low, and it is easy to miss the opportunity of rescue

Embodiment 1

[0046] Refer Figure 1-9 As shown, the articula-damfill anti-roof of the present invention is mainly due to the moller kill pillow, the separation limit wooden pile 3, the prefabricate beam 8, the unit-type light steel holder 22, water injection rubber bag 31 and the anti-wave rack Equisical. In the rush of the embankment without the concrete anti-wave wall area, the dike opens the binding groove, and the prefabricated strip 8 is provided in the binding groove, and the separation limit wooden pile 3 is provided in the outer side of the preform pair 8, in the prefabricated Beam 8 and the separated limit wooden pile 3 stack the ferrous pillow, and fill the soil 4 on the side of the pillow pillow. In the outer side of the concrete, the anti-wave wall 20 is mounted by the pre-buried screw, the anti-wavering frame is placed on the outside of the anti-wave wall 20, and the anti-wave frame is stacked in the water rubber bag 31. The finishing rubber bag 31 surface is covered with a finite ...

Embodiment 2

[0055] This embodiment provides a construction method of an anti-roof bike buffar of earth-staple dam, including the following steps:

[0056] 1) First remove the dike peel, debris, etc. before the construction, and set up the rescue measurement control network in the ground, monitor the change in water, the displacement, deformation, and sedimentation of the rescue, and the subcrement of the accumulation, Perform measurements and stake out.

[0057] 2) Before the water level is rapidly rising, the unit-type light steel holder 22 is installed in time, and the unit-type light steel holder 22 manually helped to hoister to the outer side of the anti-wave wall 20, and the oblique screw with the water slope 1 after the position is corrected. 23 and the anti-wave wall 20 The pre-buried lateral screw 21 is anchored.

[0058] 3) In the rush of the embankment without the concrete anti-wave wall area, the shavings are grounded, and the binding tank is excavated along the edge of the canow c...

Abstract

The invention relates to a construction method of an anti-overflow composite sub-dike of an earth-rock dam. The method comprises the following steps of 1) a base surface is cleaned, and a rescue measurement control network is established; (2) unit type light steel supporting frames are installed; (3) a combination groove is excavated in the levee top; (4) prefabricated strip beams are installed; (5) a separated limiting timber pile is driven; (6) a willow pillow jig frame is laid; (7) a core-filled willow pillow is made and stacked; (8) a soil berm is filled; (9) a wave-resistant frame is installed; 10) a water-injected rubber bag is constructed; and 11) wave-resistant frame assembly type inclined struts and limiting nets are installed. The method has the beneficial effects that the core-filled willow pillow is adopted for rescuing and protecting a dike section of a concrete-free wave wall area, the rescuing and protecting efficiency is greatly improved, meanwhile, the prefabricated strip beams and the separated limiting timber pile are arranged in an auxiliary mode, the stability of the willow pillow sub-dike is effectively enhanced, and the method has the multiple technical advantages of being high in efficiency, high in stability, low in cost and the like.

Description

Technical field [0001] The present invention relates to the construction method of anti-roof bonuses of earthstone dam, belonging to the field of water conservancy engineering, which is suitable for the construction of dams in the flood season. Especially for the unwitter of the dike, there is a large-scale anti-wave wall, but the wind is large, and the soil is difficult And local Liuyuan rich grabbing paragraph. Background technique [0002] my country is a country with severe floods. It has invested huge funds and human resources. It has built an unprecedented flood control project, forming a large river flood control system with flood control project as the core, and has played a huge role in economic development and social stability. , Has achieved huge social economy and environmental benefits. Of course, the local flood disaster is still there. When the actual flood bit exceeds the existing divertine top elevation, the overcome of the crowd will soon causing the buffer of t...
