Construction method for upcrossing existing electric power tunnel on open trench tunnel
The invention relates to a construction method for upcrossing an existing electric power tunnel on an open trench tunnel. The construction method for upcrossing the existing electric power tunnel on the open trench tunnel comprises the following steps of analyzing the influence of the open trench tunnel on a structure of the electric power tunnel, carrying out site formation and backfill construction, carrying out continuous wall groove wall reinforcement construction, carrying out guide wall and underground diaphragm wall construction, carrying out guard post and bench pile driving construction, carrying out SMW construction method pile driving construction, carrying out base foundation reinforcement and gravity type cement retaining wall construction, carrying out crown beam, support beam and foundation pit excavation construction, carrying out major structure construction, and carrying out roof foundation pit backfill construction. The method can be suitable for the construction onupcrossing the existing electric power tunnel on an open cut section at a short range under a deep-thick sludge layer soft fluid-plastic state condition, and has the characteristics of low construction cost and high construction safety.
一种明挖隧道上穿既有电力隧道施工方法，包适以下步骤：明挖隧道对电力隧道结构影响分析，场地平整及回填施工，连续墙槽壁加固施工，导墙及地下连续墙施工，围护桩和板凳桩施工，SMW工法桩施工，基底加固及重力式水泥挡土墙施工，冠梁和支撑梁及基坑开挖施工，主体结构施工，顶板基坑回填施工。该方法能够适用于在深厚淤泥层软流塑状态条件下明挖区间近距离上穿既有电力隧道的施工，具有施工成本低、施工安全性高的特点。
