block

Abstract

The invention discloses a building block, which includes a block body laid on the outer surface of a dam body facing the water to form a water-facing surface, and the block body is on the near water surface facing the water side and the far water surface facing away from the water side. At least one pressure relief through hole is arranged between them, and the diameter of the end of the pressure relief through hole close to the water surface is larger than the diameter of the other end. The beneficial effects of the present invention are: since there are seven rounded platform-shaped pressure relief through holes, which are small inside and large outside, between the near water surface and the far water surface of the block, it is beneficial to plant growth, beautify the ecological environment, and facilitate the pressure relief through holes. Hole filter type pressure relief to prevent sediment loss and fundamentally solve the problem of collapse of the entire facing water surface formed by laying blocks; since the far water surface of the block has at least a pair of pits with small inside and large outside and side openings, It makes it easy for the block to obtain reliable adhesion of the dam body sediment, and at the same time, it is convenient for the operators to obtain a reliable force space when transporting and laying the block.

Description

technical field [0001] The invention relates to a construction material for a water conservancy project, in particular to a block used for constructing the water facing surface of a dam on both sides of a reservoir and a water diversion channel. Background technique [0002] With the development of society and the advancement of technology, people's understanding of natural phenomena is getting deeper and deeper. In order to improve the living environment and adapt to the uneven rainfall in nature, the ancestors began to build reservoirs and diversion channels to store water during the wet season. Water, releasing water during the dry season, and directing rainwater along the trend, until the modern use of reservoirs for hydropower generation to benefit mankind, and use of water diversion channels for shipping. The evolution process of the construction of the facing water surface of the reservoir and the diversion channel from ancient times to the present is as follows: the ...

Problems solved by technology

The evolution process of the construction of the facing water surface of the reservoir and the diversion channel from ancient times to the present is as follows: the originally compacted soil slope, due to the weak ability of the soil to resist water wave or tidal erosion, especially the washing of strong winds and waves, it often needs maintenance and repair , the input of manpower and material resources is huge; later, when laying stones on the soil slope, because there are large gaps between the stones, the soil in the gaps is eroded by the wind, waves or tidal water. The water surface of the rocks far away from the water collapsed due to the loss of support. Although the water surface paved with stones is more durable than the mud surface, it still has a fatal weakness after all; Regularly shaped blocks are laid closely, which effectively solves the problem of wind waves or tides entering the gaps and eroding the sediment on the far water surface of the blocks. However, although the gaps between regular shaped blocks are close and nearly sealed, leakage cannot be prevented after all. As a result, when the water level is high, over a long period of time, the side facing the water formed by laying blocks will be filled with the water level at the same height as the water surface due to leakage. capacity in order to meet a larger flood peak, the reservoir or diversion channel needs to lower the water level urgently in a short period of time. The blocks are under outward pressure. When the water level difference is large enough, the adhesion of the blocks on the lower side of the facing water surface is not enough to overcome the pressure generated by the water level difference between the inner and outer sides, and they will be pushed out, causing the entire facing water surface to collapse.

In addition, due to the dense laying of the blocks, plants cannot grow on the surface, and there is no vitality, which is inconsistent with the current people's environmental ecological concept.
