宣惠河疏浚工程,是河北省一項大型除涝治碱工程。在河道疏浚的同时,沿河要修建許多桥梁。宣惠河工程主要是依靠当地群众施工的項目,由于缺乏施工机械設备和施工技术力量,为了达到“河成桥通”的要求,必須設計出便于群众建桥的方案。河南省采用的火箭錐钻孔灌注混凝土井柱建桥,是一种多快好

Xuanhui River dredging project is a large-scale water and alkali treatment project in Hebei Province. Dredging along the river, along the river to build many bridges. Due to the lack of construction machinery and equipment and construction technology, the project of Xuanghuihe River mainly relies on the construction of local people. In order to meet the requirements of “river into bridge”, it is necessary to design a plan to facilitate mass bridge construction. Henan Province, the use of rock cone drilling perfusion concrete shaft construction bridge, is a much faster and better
