石屑水泥管在农田地下排水工程中的推广应用

Thepublicity and appliance of the stone ballast cement pipes in the underground drainage engineerings of the agriculture land

通过技术引进和试验，利用当地采石场废弃的石屑研制经济有效的暗管管材，应用治理渍害稻田地下暗管排水工程技术，并合理确定暗管埋深及间距，有效地排除了田间渍水，改善了土填生态环境，提高了作物产量。同时进一步研究了石屑水泥管管材配比及管子结构，提高了管材性能，减少了工程投资，并对石屑水泥管地下排水工程的施工和运行管理等进行了探讨和总结。

In order to get a good use of the stone ballast which was abandonedat the lolal stone pit. we studied the material of the dark gipe which is econo-mic and effective. Through the intraduced technique and the experiment. we uaedthe underground drainage engineering technigue of the dark pipees for dealing withthe. water loggod farm land . and determined reasonablely the. embeded depth and spac- ing of the dark pipes. The water logging in the farm land was dischatged effec- tively. The eeological environment of the soil was improved. The harvest outputwas increased. At the same time we studied further the material dispensationformula and the structure of the stone bdllast cement pipes. The property ofthe pipe material was improved. The engineering investment was teduced. Thispaper probed and summarized the construction and operating managerrent etc. on the underground drainage engineering of the stone ballast cement pipe.
