Steel casing pipe jacking well construction method
The invention discloses a construction method of a steel casing pipe-jacking well. The construction method of the steel casing pipe-jacking well comprises the following steps: selecting a corresponding steel casing section according to a construction environment; determining the position of a foundation pit, and excavating at the position of the foundation pit to form the foundation pit; the steel casing sections are subjected to static pressure sinking section by section till the steel casing sections sink to the preset height, and a preliminary pipe jacking well is formed; high-pressure jet grouting pile reinforcement is conducted on the earthwork and the pit bottom position of the preset in-out hole position surrounding the preliminary pipe jacking well to form a reinforcement area; and hole digging treatment is conducted at the preset hole entering and exiting positions of the preliminary pipe jacking well to form a hole entering and exiting opening, and pipe jacking pipelines are assembled at the hole entering and exiting opening positions correspondingly. According to the construction method of the steel casing pipe-jacking well, the traditional form of row piles and a waterproof curtain is changed, the construction cost is reduced, the overall construction space is also reduced, and the overall construction difficulty is also reduced.
一种钢护筒顶管井施工方法，该钢护筒顶管井施工方法包括如下步骤：根据施工环境选取对应的钢护筒段；确定基坑位置，并在基坑位置开挖以形成基坑；逐段将钢护筒段进行静压下沉，直至钢护筒段下沉至预设高度，以形成初步顶管井；在围绕初步顶管井的预设进出洞位置的土方及坑底位置处进行高压旋喷桩加固以形成加固区域；在初步顶管井的预设进出洞位置处进行挖洞处理，以形成进出洞口，在进出洞口位置处分别装配顶管管道。该钢护筒顶管井施工方法，改变了传统排桩+止水帷幕的形式，降低了施工成本，且整体的施工空间也随之减小，整体的施工难度也随之下降。
