Abstract

The invention discloses a method for blocking holes by using split bolts. The method is characterized by coating and compacting bolt holes layer by layer by using cement mortar; and carrying out abrasive-compacting and hole sealing on the surface by using a hole-sealing die. Compared with the traditional method for blocking the holes, the method not only ensures blocking compactness and avoids leakage, but also ensures the appearance effect of concrete and improves construction quality; and moreover, the method has the advantages of cost conservation, high economical efficiency and practicality and higher popularization and application values, thereby generating ideal economic and social benefits.

Description

technical field

[0001] The invention discloses a method for plugging holes, in particular to a method for plugging holes of pull bolts, which belongs to the technical field of construction engineering. Background technique

[0002] At present, with the widespread use of concrete walls in our country, in the formwork construction with waterproof requirements for the walls, when the concrete walls of buildings are poured, pull bolts are generally used. After the formwork is removed, the total length of the bolts should be 2 / 3 or so exposed parts are cut off. In the formwork construction where the wall has waterproof requirements, after the pull bolts are cut off, the hole needs to be plugged. In actual construction, the method of directly sealing the partition with an iron trowel is generally used, which is easy to cause the plugging to be incomplete. As a result, the leakage phenomenon in this part will affect the apparent quality of the wall concrete. Contents of the inv...
