Construction method of waterproof operation on basement floor with multiple anti-floating anchor nodes

Abstract

The invention discloses a construction method of waterproof operation on a basement floor with multiple anti-floating anchor nodes. The construction method is characterized in that the construction method includes the following steps that a step a, raw materials for construction are prepared according to the waterproof design of the basement floor, a step b, after the basement floor construction is completed, a basement floor surface is brushed with neat cement paste, a step c, a roughened surface of the basement floor is brushed with waterproof mortar for leveling, a step d, after gravel is laid on a leveling layer, a frog rammer is used for pressing and leveling a gravel permeable layer, a step e, a non-woven fiber cloth fully covers the gravel permeable layer, a step f, a C20 fine aggregate concrete surface layer with the thickness of 30mm is laid on the surface of the non-woven fiber cloth, and a step g, waterproof coiled materials are laid on the fine aggregate concrete surface layer, and finally, a C20 fine aggregate concrete surface layer with the thickness of 50mm is laid. The construction method of waterproof operation on the basement floor of a deep foundation pit has theadvantages that a waterproof layer is placed on the basement floor surface, a water drainage layer is arranged to effectively solve the water seepage problem in the later period, the waterproof engineering quality is safe and reliable, the construction speed is fast, construction efficiency is improved, labor is saved, and the engineering cost is lowered.

Description

technical field [0001] The invention relates to a method for waterproofing a basement floor, in particular to a construction method for waterproofing a basement floor at a joint of multi-floating anchor rods. Background technique [0002] With the continuous expansion of the scale of the construction industry, high-rise buildings have become the mainstream of the construction industry. The depth of the basement of the deep foundation pit is as low as -10 meters. The coastal areas are rich in water resources and the groundwater level is high. The requirements for the anti-floating ability of buildings are strict. It is often necessary to add many anti-floating anchors to supplement it, which makes the waterproof construction of the basement floor difficult. Using traditional waterproof construction technology, there are many nodes at the anchors, which greatly increases the hidden danger of water seepage in the later stage.

AI Technical Summary

Problems solved by technology

Although this technical solution can cut off the seepage path of groundwater and achieve a waterproof effect, it uses the anchor bag for grouting, opens the extended end plate, and presses cement mortar according to the design pressure and grouting volume to expand the anchor bag Formed technical measures are difficult to implement, labor-intensive, costly, and the construction period is long, which increases the cost of the project

[0004] Therefore, there are above-mentioned inconveniences and problems in the known anti-floating anchor rod node basement floor waterproofing method
