Water seepage control construction method for waterproof construction of karst water-rich geological underground structure

Abstract

The invention relates to the field of basement water-rich geological structure waterproof construction, in particular to a water seepage control construction method for karst water-rich geological underground structure waterproof construction. The problem that waterproof construction is affected due to the fact that existing underground structure waterproof construction only focuses on construction self-waterproofing and is poor in waterproof effect and water pressure and waterways of foundation pit water seepage always exist. The water seepage control construction method includes the steps of water seepage control on baseboard waterproof construction, waterproofing and water draining of baseboards and continuous wall corners, water seepage control on wall waterproof construction, water seepage control on portal waterproof construction, and water seepage control on waterproof construction of expansion joints and post-cast strips. A water seepage control technique at positions such as the baseboards, station structure side walls, the expansion joints and the post-cast strips is realized, structure waterproof performance is improved, waterproof construction is ensured to be performed in a water-free environment, quality of waterproof construction and cement construction under the karst water-rich geological conditions is guaranteed, simplicity and convenience in technological operation are realized, and the water seepage control construction method is wide in application range, reliable in technology, high in superiority and convenient to popularize and apply.

Description

Technical field [0001] The invention involves the structural waterproof construction field of base -rich geology, and is specifically for a waterproof construction method of waterproof waterproofing waterproofing waterproof construction of rock -soluble water geology. Background technique [0002] Public knows that there are two sources of leakage during the waterproof construction of underground structure, such as figure 1 It is shown that first is to flow up from the rocky gap, rock -dissolved water, or sand layer at the bottom of the wall, commonly known as the pipe; the second is the leakage of the continuous wall, the continuous wall leakage is easy to block, and the impact in actual construction does not have base water without base water.Come serious.like figure 2 It shows that the water pressure in the pits between the gap between the continuous wall and the structure wall will replace the water pressure of the continuous wall seepage, which will fail the design of the wa...

Problems solved by technology

[0004] In order to solve the problem that the existing underground structure waterproofing construction is mainly based on the self-waterproofing of the structure, the waterproofing effect is poor, and the water pressure and waterway of foundation pit seepage always exist and affect the waterproofing construction, it provides a waterproofing method for karst water-rich geological underground structures.
