Large-pipe-diameter buried pipe laying structure in collapsible loess area and construction method
The invention discloses a large-pipe-diameter buried pipe laying structure in a collapsible loess area, and belongs to the technical field of municipal engineering or water conservancy projects. The large-pipe-diameter buried pipe laying structure comprises buried pipes, drainage ditches, seepage wells, longitudinal curtains, transverse curtains, rolling cushion layers, sleeve valve pipes, grouting material layers and paving layers. A construction method of the large-pipe-diameter buried pipe laying structure in the collapsible loess area comprises the steps that a vertical isolation belt is formed in a foundation below the buried pipes through the longitudinal curtains and the transverse curtains, the sleeve valve pipes are used for pouring grouting materials to the bottom of the foundation in a pressure mode, the grouting material layers are formed at the bottom of the foundation, the paving layers are laid on the foundation at the tops of the curtains, the rolling cushion layers aresequentially laid on the paving layers, the drainage ditches are excavated in the two sides of the rolling cushion layers, the seepage wells are arranged in the drainage ditches at intervals, then anti-seepage films are laid, water-permeable aggregates are thrown in the drainage ditches and the seepage wells, finally, the buried pipes are laid above the anti-seepage films, and pipe ditches are backfilled. The large-pipe-diameter buried pipe laying structure is simple in process, green and environment-friendly, the construction speed is high, and good economic benefits and social benefits areachieved.
本发明公开了一种湿陷性黄土地区大管径埋管敷设结构，属于市政工程或水利工程技术领域。包括埋管、排水沟、渗水井、纵向帷幕、横向帷幕、碾压垫层、袖阀管、注浆料层、铺盖层。一种湿陷性黄土地区大管径埋管敷设结构的施工方法，通过采用纵向帷幕、横向帷幕在埋管下方地基中形成竖向隔离带，袖阀管向地基底部压力灌注注浆料，在基础底部形成注浆料层，在帷幕顶部基础上铺设铺盖层，其上依次铺设碾压垫层，碾压垫层两侧开挖排水沟，排水沟中间隔地设置渗水井，然后铺设防渗膜，在排水沟、渗水井中抛置透水骨料，最后在防渗膜上方敷设埋管，管沟回填。本发明工艺简单，绿色环保，施工速度较快，具有良好的经济效益和社会效益。
