Abstract
The invention discloses a method for polishing, bonding and waterproofing concrete suitable for a deep foundation pit pile body, which comprises the following steps: before pile body chiseling, a toothless saw is adopted to cut along the pile body at the designed elevation position of the pile body, the cutting depth is the thickness of the steel bar protective layer, and steel bars cannot be cut. And (4) adopting an air pick to pick and chisel the pile body concrete until the distance between the pile body and the designed elevation is 5 cm, stopping the construction of the air pick, and manually picking and chiseling the pile body concrete until the designed elevation is reached. And (4) polishing the external corner and the pile core part of the pile body by using a polishing machine until the surface of the concrete is flat. The surface of the pile body is washed by clear water until no particles such as dust and the like exist on the surface. Cement mortar is adopted to level the adjacent base layer of the underground pile body, the uneven position of the adjacent base layer is repaired, and the joint of the underground pile body and the adjacent base layer is provided with a circular arc internal corner to facilitate the adhesion with the waterproof coiled material. The adjacent base layer of the underground pile body is pasted with the waterproof coiled material, so that waterproof treatment is realized. The integrity of the waterproof coiled material of the underground pile body is ensured, and the waterproof effect of the pile body is improved.
Description
Technical Field
The invention relates to the field of concrete waterproofing, in particular to a method for polishing, bonding and waterproofing concrete suitable for a deep foundation pit pile body.
Background
With the rapid development of the building industry, high-rise (super high-rise) residences, businesses and large underground garages are more and more, so that underground waterproof engineering becomes a problem to be solved by buildings more and more, and particularly, the treatment of pile bodies in the underground engineering is particularly important. The waterproof basic layer treatment of the underground pile body in the existing building is a part which is often overlooked relatively easily and is also a link which is easy to operate roughly, so that the method for preventing the water seepage of the pile body part by adopting an effective method has great popularization significance.
Traditional pile body base course is handled and is only after scraping the chisel with pile body concrete, carries out waterproofing after simple processing accomplishes the base course and handles, very easily causes waterproofing membrane to paste easy fracture and hollowing in the department with pile body all around, if produce the shrink crack in bottom plate bulky concrete construction and just take place in pile body department, then cause the condition of bottom plate infiltration very easily, seriously influenced the quality of building.
Disclosure of Invention
The invention aims to solve the technical problem of providing a method for polishing a waterproof base layer of an underground pile body of a building. The polishing treatment method has good waterproof effect of the pile body, ensures the integrity of the waterproof coiled material of the underground pile body, avoids cracking and hollowing, and effectively improves the waterproof effect of the underground pile body, thereby ensuring the quality of buildings. The technical scheme is as follows:
in order to solve the technical problem, the processing method for polishing the waterproof base layer of the underground pile body comprises the following steps:
the method comprises the following steps: before pile body chiseling, a toothless saw is adopted to cut along the pile body at the designed elevation position of the pile body, the cutting depth is the thickness of the steel bar protective layer, and steel bars cannot be cut.
Step two: and (4) adopting an air pick to pick and chisel the pile body concrete until the distance between the pile body and the designed elevation is 5 cm, stopping the construction of the air pick, and manually picking and chiseling the pile body concrete until the designed elevation is reached.
Step three: and (4) polishing the external corner and the pile core part of the pile body by using a polishing machine until the surface of the concrete is flat.
Step four: the surface of the pile body is washed by clear water until no particles such as dust and the like exist on the surface.
Step five: cement mortar is adopted to level the adjacent base layer of the underground pile body, the uneven position of the adjacent base layer is repaired, and the joint of the underground pile body and the adjacent base layer is provided with a circular arc internal corner to facilitate the adhesion with the waterproof coiled material.
Step six: the adjacent base layer of the underground pile body is pasted with the waterproof coiled material, so that waterproof treatment is realized.
Compared with the prior art, the invention has the beneficial effects that: this application is before realizing waterproof pasting operation, picks the chisel through with the pile body and polishes the processing, has replaced traditional pile body basic unit to handle and has only picked the chisel with pile body concrete, simply handles the basic unit surface, makes the working face more level and more smooth, more effectual water-proof effects that reaches, ensures underground pile body waterproofing membrane's integrality, avoids fracture and hollowing, has effectively improved underground pile body's water-proof effects to high-rise building's quality has been guaranteed.

Detailed Description
In order that the invention may be more clearly understood, the invention is described in further detail with reference to the accompanying drawings.
As shown in figure 1, the waterproof treatment method for the underground pile body of the high-rise building comprises the following steps:
the method comprises the following steps: before pile body chiseling, cutting along the reinforced concrete pile body 6 at a designed elevation position 1 by using a toothless saw, wherein the cutting depth is the thickness of a steel bar protective layer, and steel bars cannot be cut;
step two: adopting an air pick to remove concrete, picking and chiseling to remove a pile body 2, picking and chiseling to 5 cm above a designed elevation of the pile body, stopping the construction of the air pick, and manually picking and chiseling to remove the concrete 3 to the designed elevation position 1;
step three: polishing the external corner and the pile core part at the pile body position at the polishing position 4 by using a polishing machine until the surface of the concrete is flat;
step four: the surface of the pile body is washed by clear water until no particles such as dust and the like exist on the surface;
step five: leveling the adjacent base layer 5 of the underground pile body by adopting cement mortar, repairing the uneven position of the adjacent base layer 5, and making an arc internal corner at the joint of the underground pile body and the adjacent base layer 5;
step six: the adjacent base layer 5 of the underground pile body is pasted with the waterproof coiled material 7, so that waterproof treatment is realized.
