Abstract

The invention provides a waterstop pull rod with one fixed end. The waterstop pull rod with one fixed end comprises a fixed end pull rod and an adjustment end pull rod. The fixed end pull rod is connected to the adjustment end pull rod through a circular-truncated-shaped connector. The fixed end pull rod is embedded in a foundation pile. A formwork is arranged on the outer side of the adjustment end pull rod. A rubber gasket is arranged between the formwork and the circular-truncated-shaped connector. An auxiliary square wood ridge is arranged at the outer end of the formwork. Main pipe erection ridges are arranged on the outer side of the auxiliary square wood ridge and are mounted on the two sides of the adjustment end pull rod through convex clamps. The convex clamps are mounted on theadjustment pull rod through nuts. According to the novel waterstop pull rod with one fixed end, and the concrete-poured formwork using an engineering breast board is used for fixation and limitation,so that inclined struts do not need to be mounted; and the pull rod can replace an embedded steel bar, and the repair quantity in the later stage is small. The waterstop pull rod with one fixed end has the advantages that the construction quality can be well controlled, the construction period is shortened, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction equipment, in particular to a single-ended fixed water stop tie rod. Background technique [0002] The pile-retaining plate combination structure (pile-plate retaining wall structure) is widely used in urban infrastructure construction and upgrading projects. Common structure for blocking protection. When the depth of the cutting foundation pit is large or the cantilever height of the exposed part of the retaining wall is large, the construction of the retaining plate is often restricted by the lateral limit of the vertical formwork and formwork, and the construction process is complicated, which is prone to slurry leakage, water seepage and surface defects. And other issues. In engineering practice, there is a need for an anchor rod that can be constructed quickly, has a low cost, can perform water-stopping, play a role in the fixation and lateral deformation limit of the...
