Embodiment 1

[0028] 1) Cleaning of the grouting opening: After the anti-floating anchor rod is grouted and reaches the design strength, clean the grouting opening, and remove the scale or oil stains on the anchor bar.

[0029] 2) Blocking of fine stone concrete: pour C15 fine stone concrete at the grouting port after cleaning, vibrate and pour compactly, and form a whole with the adjacent concrete cushion, without leaving construction joints, and the height is the same as that of the surrounding cushion The level of the top of the storey is the same, and the filling of fine stone concrete can not only prevent groundwater from accumulating at the end of the anti-floating anchor rod, which will cause long-term corrosion of the anchor bar; at the same time, the rigid waterproof performance of fine stone concrete itself is effective to a certain extent. prevent the infiltration of groundwater.

[0030] 3) Construction of waterproof coating layer: the base is cleaned and moistened, with the cen...

Abstract

The invention discloses a waterproofing method for a joint of an anti-floating anchor rod and a bottom plate. The process comprises the following steps of: step 1, cleaning a grouting port: cleaning scale or oil stains of the grouting port and anchor ribs; step 2, blocking with fine stone concrete: pouring the fine stone concrete at the grouting port, and vibrating and pouring compactness; step 3,constructing a waterproof coating layer: evenly brushing waterproof coating layer around the anchor rod; step 4, constructing an impervious concrete round pier and applying waterproof sealing paste:pouring the impervious concrete round pier around the anchor rod, sealing the junction between the concrete round pier and a leveling layer with sealing paste; step 5, pasting a waterproof roll; step6, constructing a fine stone concrete waterproof protection layer; step 7, installing a water stop steel plate; and step 8, pouring an impervious concrete bottom plate. The waterproofing method for the joint of the anti-floating anchor rod and the bottom plate has the advantages of being remarkable in waterproof effect, simple in manufacturing process, and the like; the possibility of water leakage at bottom plate of the anchor rod is greatly reduced, the engineering amount of leaking stoppage in the later stage of the bottom plate is reduced, the cost is reduced, and the construction qualityof the bottom plate of a concrete basement is ensured.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method of waterproofing the joint between an anti-floating anchor rod and a bottom plate. Background technique [0002] Anti-floating anchor rod is a kind of anti-floating measures for underground structures in construction projects. Anti-floating anchors are different from ordinary foundation piles, and have their own unique properties. The biggest difference from ordinary foundation piles is that foundation piles are usually compression piles, and the pile body bears the building load pressure, and the force is from the top of the pile to the bottom of the pile. Transmission, the force of the pile body changes with the change of the building load; while the anti-floating pile bears the tensile force on the uplift pile body, and the force of the ordinary anti-floating pile is also transmitted from the top of the pile to the bottom of the pile, and the force on the pile body changes...
