Abstract
The application method of the autoclase type cement mortar that foams in anchor pole or anchorage cable anchoring section of the invention forms anchoring body by that will be added with vulcanizing agent, portland cement, fine aggregate, rubber powder, foaming agent, paraffin, microwave absorption, reinforcing agent, filler, modified flowable, the foaming autoclase type cement mortar injection anchor pole of dispersing agent or anchorage cable anchoring section periphery.When removing anchor pole or anchor cable, applying microwave field into anchoring body, cement mortar internal temperature increases rapidly, and promote foaming agent foam, deflate, fine aggregate volume expansion, and then make cement mortar spalling, voluntarily it is crushed.Since the chipping rear intensity of cement mortar is greatly lowered, so that carrying out the anchor pole or cable bolting structure of grouting anchoring using such cement mortar, convenient for removing, save the time, reduction difficulty of construction.
Description
Technical field
The invention belongs to construction cement mortar technical fields, and in particular to foam in anchor pole or anchorage cable anchoring section
The application method of autoclase type cement mortar.
Background technique
With the development of China's urban construction cause, urban population density constantly increases, urban land especially core space
The soil in domain increasingly lacks, important supplement of the underground space as urban ground space, and development is in great demand.For sufficiently benefit
Depth with Underground Space Resource, foundation pit is deeper and deeper, and anchor-pull brace technology is support, the pull-type supporting of anchor from structure stress
One kind of structural system, since it has many advantages, such as that reasonable stress, low cost, supporting stability are good, foundation construction is convenient, in depth
It is widely used in foundation pit, but it has a fatal hidden danger, as a kind of interim supporting construction, is completed in main structure
Afterwards, it will be retained in soil layer, it is very big for the influence of post city's underground space development, especially for planning under town road
Subway tunnel for be very intractable underground obstacle.Currently, someone main for the method for dismounting of anchor-pull brace technology
Work abolishes, mechanical breaking, demolition blasting and four kinds of saw cut method of rope.It is low manually to abolish method construction efficiency, excess-three kind method,
Significant shock will be formed in demolishing process, and larger impact is brought to existing structure, surrounding building and underground utilities.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide the autoclase type water that foams in anchor pole or anchorage cable anchoring section
The application method of cement mortar, so that the anchor pole or anchor cable solid that are perfused and are formed using such cement mortar, convenient for removing, section
It makes an appointment, reduces difficulty of construction.
The application method of the autoclase type cement mortar provided by the invention that foams in anchor pole or anchorage cable anchoring section, including it is as follows
Step:
