Self-expansion type anti-blocking flood water drainage dam for water conservancy project
The invention discloses a self-expansion type anti-blocking flood water drainage dam for a water conservancy project, and belongs to the field of dams. The self-expansion type anti-blocking flood water drainage dam for the water conservancy project comprises a dam body; a plurality of uniformly distributed water discharge openings are formed in the middle part of the dam body in a cut manner; theinner walls of the water discharge openings are provided with wall-sticking sheath layers; by means of the arrangement of the wall-sticking sheath layers and power hardening layers, under the action of water pressure during floor water drainage, the wall-sticking sheath layers and the power hardening layers can have deformations fitted to the inner walls of the water discharge openings and becomehardened to generate a certain buffer effect on the water pressure, effectively improve the strength of the dam and prolong the service life; meanwhile, under the action of the water pressure, a pre-disintegration layer is gradually disintegrated, and an expansion air bag is exploded, so that a hidden expansion slot is emptied and communicates with the water discharge openings, which realizes expansion of the water discharge openings, effectively increases the flood water drainage volume, increases the flood water drainage speed and relieves the pressure of excessively gathered flood water onthe dam; and therefore, the situation that the dam is destroyed by rush of water is effectively avoided, and the potential safety hazard is reduced.
本发明公开了一种水利工程用自扩容型防堵排洪堤坝，属于堤坝领域，一种水利工程用自扩容型防堵排洪堤坝，包括堤坝本体，堤坝本体中部开凿有多个均匀分布的泄水口，泄水口内壁设置有贴壁护套层，可以通过贴壁护套层和力硬化层的设置，在泄洪时的水压作用下，贴壁护套层和力硬化层能够发生贴合泄水口内壁的形变并变硬，能够对水压产生一定的缓冲作用，有效提高本堤坝强度，延长使用寿命，同时在水压作用下，预崩解层逐渐崩解，扩容气囊炸裂，从而使得隐形扩容槽被空出并与泄水口连通，从而实现泄水口的扩容，有效加大泄洪量，提高泄洪速度，缓解过多聚集的洪水对本堤坝造成的压力，从而有效避免本堤坝被冲毁的情况，降低安全隐患。
