Rapid blocking method for groove steel sheet pile supporting notch of existing pipeline
The invention discloses a rapid blocking method for a groove steel sheet pile support gap of an existing pipeline, which comprises the following steps of: S1, quickly splicing plates and vertically staggering joints to form a wall body structure by adopting on-site prefabricated reinforced concrete tongued and grooved plates; s2, the reinforced concrete matchboard at the position of the existing pipeline is specially prefabricated into two plate blocks with semicircular holes according to the pipe diameter of the existing pipeline; s3, after the trench is excavated, the reinforced concrete matchboards are quickly spliced into a closed structure at the notches; and S4, when the groove steel sheet piles are constructed, the two steel sheet piles at the supporting notch are welded with channel steel, and then the channel steel and the steel sheet piles are driven into a soil body together. The retaining wall is quickly assembled by adopting field prefabricated reinforced concrete tongued and grooved boards, a supporting system is formed by utilizing vertical and horizontal channel steel, a reliable closed structure is formed at a notch in time, normal construction of a groove and a pipeline is ensured, and meanwhile damage to an adjacent existing building caused by collapse of soil on the periphery of the groove is avoided.
本发明公开了一种用于既有管线的沟槽钢板桩支护缺口快速封堵方法，包括以下步骤：S1、采用现场预制钢筋混凝土企口板，将板块进行快速拼接，竖向错缝，形成墙体结构；S2、既有管线处的钢筋混凝土企口板根据既有管线管径专门预制成两个带半圆洞口的板块；S3、沟槽开挖完成后，在缺口处将钢筋混凝土企口板快速拼接成封闭结构；S4、沟槽钢板桩施工时，支护缺口处的两根钢板桩焊接槽钢，随后与钢板桩一道打入土体。本发明采取现场预制钢筋混凝土企口板快速拼装成挡墙，并利用竖向和水平槽钢形成支撑体系，对缺口处及时形成可靠封闭结构，保证了沟槽及管道正常施工，同时避免了因沟槽外围土体塌方引起临近既有建构筑物的损坏。
