摘 要

高店村沟排水渡槽位于河北省邢台市所辖沙河市高店村西北，位于总干渠南沙河倒虹吸南侧，是南水北调中线工程总干渠上的一座左岸排水建筑物。

渡槽为跨越式建筑物，采用矩形渡槽排架结构，按三级建筑物考虑。设计地震烈度为8。

渡槽上游高程90.00m，水位88.55m；下游高程89.50m，水位89.00m，不考虑交通要求，只需设置人行道板；无通航要求。

渡槽总长60m，进口渐变段6m，出口渐变段10m，渡槽进口底部高程90.209m，出口底部高程89.938m。渡槽槽身净宽4m，水面宽5.0m，侧墙厚0.2m，底板厚0.4m，人行道板宽度为1.0m。

本设计对渡槽进行了认真的方案比选和详细的尺寸设计，并针对设计要求进行了安全校核，保证建筑物的安全运行。

关键词：高店村、渡槽、槽身、建筑物。

Abstract

Gao dian village is located in hebei province xingtai city had jurisdiction over the village ditch drainage aqueduct Gao dian village northwest, located in the south area of nansha river inverted siphon of the main canal is the main canal of south-to-north water transfer project on a left bank drainage structures. Aqueduct for leap buildings, bent rectangular aqueduct structure, the level 3 buildings. Design earthquake intensity is.

Aqueduct upper elevation, water level; Elevation, downstream water level, regardless of the traffic requirements, only need to set up the pavement plate; No navigation requirements.

Aqueduct 60 m, gradual change section import, export, the gradual elevation at the bottom of the aqueduct import and export the bottom elevation. Aqueduct with width, wide water surface, side wall thickness, plate thickness, plate width to the pavement.

This design has carried on the earnest to aqueduct scheme is chosen and the size of the detailed design, and design requirements for the security check, ensure safe operation of the building. Keywords: high shop village, aqueduct, slot, and buildings.
