Embodiment Construction

[0028] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0029] It should be noted that when an element is referred to as being "disposed on" or "fixed on" another element, it can be directly on the other element or a central element can also be present. When an element is said to be "fixed to" another element, or "fixedly connected" with another element, they can be fixed in a detachable or non-detachable manner. When an element is considered to be "connected" or "rotatably connected" to another element, it may be directly connected to the other element or a centering element may exist at the same time. The terms...

Abstract

The invention discloses a sealing water method and a sealing water structure of an anchor cable hole of a water-rich stratum underground diaphragm wall. The sealing water method comprises the following steps: drilling a diaphragm wall body and a soil body to obtain an anchor cable hole, and adopting a flow control piece to block fluid during the drilling treatment process; putting an anchor cablesteel strand in the anchor cable hole, and filling first solidification solution in the anchor cable hole to fix the tail part of the anchor cable steel strand so as to obtain an anchorage section with a preset length; filling second solidification solution in the anchor cable hole until the anchor cable hole is full to obtain a first blocking section; arranging a waterstop piece at the opening ofthe anchor cable hole, and stretching, drawing and locking the anchor cable steel strand to enable the waterstop piece to block the opening of the anchor cable hole. The sealing water method and thesealing water structure can effectively carry out sealing water treatment on the anchor cable hole to ensure the construction quality.

Description

Technical field [0001] The invention relates to the technical field of anchor cable hole water sealing, in particular to a method for sealing water of an anchor cable hole of an underground continuous wall in a water-rich stratum and a water sealing structure thereof. Background technique [0002] Prestressed anchor cables are mainly suitable for viscous and impervious stratum or stratum with low water head. It is often required that there are no important buildings around, and temporary precipitation during construction is also allowed. For water-rich stratum conditions with abundant groundwater, many rock fissures, thick sand and restrict temporary precipitation outside the foundation pit, the stability of anchor cable holes, changes in water level and soil deformation are related to stratum conditions. Can it effectively solve the water sealing problem in the whole process of construction? The traditional water-sealing method and water-sealing structure of anchor cable holes ...
