Construction method of double-row prestressed pipe pile hanging plate continuous wall
The invention relates to a construction method of a double-row prestressed pipe pile hanging plate continuous wall. The construction method is characterized by comprising the construction steps of a crown beam and pipe pile core grouting synchronous construction technology, a pile top crown beam formwork system, a cast-in-situ hanging plate formwork system, a prefabricated hanging plate from top to bottom section by section pressing, sinking and installing technology and a prefabricated plate and pipe pile gap geotechnical cloth wrapping, grouting and filling technology. The invention belongs to the field of hydraulic engineering construction, and not only can improve the stability of a cast-in-place hanging plate formwork structure, improve the mounting speed and effect of a prefabricated hanging plate, improve the construction quality and efficiency of a top beam formwork and the bearing capacity of the structure, but also ensures the pile forming quality and appearance, saves land resources, reduces noise pollution on site, reduces dust, and reduces the construction cost. The construction efficiency and quality on site are greatly improved, and good technical and economic benefits can be obtained when the method is applied to actual engineering.
本发明涉及双排预应力管桩挂板连续墙的施工方法，其特征在于施工步骤包括：冠梁与管桩灌芯同步施工技术，桩顶冠梁模板体系，现浇挂板模板体系，预制挂板自上而下逐节压入沉放安装技术，预制板与管桩空隙土工布包裹注浆填充技术。本发明属于水利工程施工领域，不但可以提高现浇挂板支模结构稳定性，提高预制挂板的安装速度和效果，提高冠梁模板施工质量和效率，以及结构的承载力，同时保证了成桩质量和外观，节约土地资源，减少了现场的噪音污染、减低粉尘，大大提高现场施工效率和质量，应用于实际工程中可取得较好的技术经济效益。
