Construction method for diversion of flood discharge channel
The invention discloses a construction method for diversion of a flood discharge channel, and aims to solve the problems that an existing flood discharge channel is crossed with a newly-built sinking tunnel, the current flood discharge channel crosses over a tunnel foundation pit, the tunnel foundation pit needs to be constructed and needs to be dismantled, and in order to ensure normal flood discharge of a reservoir during construction of the tunnel foundation pit, the existing flood discharge channel needs to be dismantled. And new diversion needs to be implemented before the flood discharge channel in the range of the foundation pit is dismantled. The diversion construction method comprises the steps that firstly, four reverse construction wells are constructed on the two sides of a flood discharge channel on the periphery of a tunnel foundation pit, five steel pipes are erected above the reverse construction wells to serve as new diversion steel pipes, water is guided to the new diversion steel pipes at the proper time, and finally the flood discharge channel to be dismantled in the range of the tunnel foundation pit is chiseled away. And the tunnel foundation pit can be normally subjected to foundation pit supporting, earth excavation and structural construction. Due to the fact that the new flow guide steel pipe is erected above the tunnel foundation pit, supporting and excavation of the tunnel foundation pit are not affected, according to the method, the concrete flood discharge channel box is newly built according to the specific gravity, the construction period is obviously shortened, and the flow guide steel pipe can be recycled.
本发明公开了一种泄洪渠导流的施工方法，现有的泄洪渠与新建的下沉隧道呈十字相交，由于现状泄洪渠横跨在隧道基坑上，要进行隧道基坑施工，必须拆除，为确保隧道基坑施工时水库能够正常泄洪，在拆除基坑范围内的泄洪渠之前须实施新的导流。本发明导流施工方法包括：首先在隧道基坑外围泄洪渠的两侧施工四座逆作井，逆作井上方架设五根钢管作为新的导流钢管，在合适的时间将水引至新的导流钢管，最后凿除隧道基坑范围内的待拆除泄洪渠，隧道基坑就可以正常进行基坑支护、土方开挖和结构施工。由于新的导流钢管架空在隧道基坑上方，因此不影响隧道基坑支护和开挖，这种方法，比重新建一个混凝土泄洪渠箱，工期明显是缩短了，而且导流钢管是可回收。
