黄河河口地区暗管排碱施工暗管埋深计算分析

Underground Pipe Alkali Discharge Construction Underground Pipe Buried Depth Calculation Analysis in Yellow River Estuary Region

暗管排碱技术是近年来自荷兰引入的科学改良盐渍土壤的工程技术,具有单次投入、短期脱碱、无人看护等优点。黄河河口地区由于自身地质、气象等特点,造成了该地区盐渍化问题极为严重,严重制约当地农业发展,传统的盐渍改良手段效果不明显。本文通过暗管埋深计算公式,结合河口地区现状,核算出适用于研究区的暗管埋深计算参数,可为今后暗管排碱施工提供技术依据,达到高效改良盐渍化土壤的目的。

Underground pipe alkali discharge technology belongs to salted soil scientific improvement engineering technology introduced from Netherlands in recent years. It has advantages of single investment,short-term de-alkalization,unattended state,etc. Salinity problems in Yellow River estuary region are extremely serious due to own geological and meteorological characteristics, thereby seriously hampering development of local agriculture, and traditional salted improvement means are ineffective. In the paper,status quo of estuary region is combined for calculating underground pipe buried depth calculation parameters by underground pipe depth calculation formula,thereby providing technical basis for underground pipe alkali discharge construction in the future,and reaching the purpose of effectively improving salted soil.
