Description
Technical field
The present invention relates to overhead power transmission line pole tower foundation construction field, and in particular to a kind of easy disintegrating sandstone place base expanding and base expanding
Structure and its guard method in base expanding and base expanding face.
Background technology
At present on severely-weathered easy disintegrating sandstone place, carry out overhead power transmission line pole tower foundation excavation when, past
Toward the protection for not carrying out base expanding and base expanding face, the severely-weathered easy disintegrating sandstone of cranny development is susceptible to local and falls block or slump phenomenon,
Prevent the geometry in base expanding and base expanding face is from reaching design requirement.Accordingly, it would be desirable to a kind of easy disintegrating sandstone place base expanding and base expanding structure and its
The guard method in base expanding and base expanding face, to guarantee the complete and stable of the geometry in base expanding and base expanding face.
Content of the invention
For the problems referred to above, the present invention provides the protection side in a kind of easy disintegrating sandstone place base expanding and base expanding structure and its base expanding and base expanding face
Method.
The purpose of the present invention employs the following technical solutions to realize：
A kind of easy disintegrating sandstone place base expanding and base expanding structure, including right cylinder section and base expanding and base expanding section, the right cylinder section is located at base expanding and base expanding structure
Center, be straight column structure；The base expanding and base expanding section excavates shape according to design geometries to surrounding from the bottom of right cylinder section
Into the inner surface of base expanding and base expanding section is base expanding and base expanding face, is coated with the cement mortar of adding Concrete accelerator and glass fibre on base expanding and base expanding face, surpasses
Fall block and backbreak partly by adding Concrete accelerator and the cement bonded sand of glass fibre in the local for going out base expanding and base expanding section design geometries
Slurry is filled up.
A kind of guard method in the base expanding and base expanding face of easy disintegrating sandstone place base expanding and base expanding structure,
Realized by following steps：
Step one：The right cylinder section for strengthening wind easy disintegrating sandstone place base expanding and base expanding structure has been dug by shaping using manual method；
Step 2：According to the design geometries of base expanding and base expanding section, hand excavation's base expanding and base expanding section is carried out using pickax；
Step 3：Block is fallen to the local occurred in base expanding and base expanding section digging process and part of backbreaking, using adding Concrete accelerator
And the cement mortar of glass fibre is filled up；
Step 4：Fall 10 minutes after block fills up end in the local to base expanding and base expanding section, the whole man to the base expanding and base expanding face of base expanding and base expanding section
Work smears the cement mortar of the thick adding Concrete accelerators of 2cm and glass fibre.
Preferably, the rapid hardening time control of the cement mortar of adding Concrete accelerator and glass fibre is in 20 minutes.
Beneficial effects of the present invention are：After hand excavation, rapid application mixes the cement mortar of accelerator and glass fibre
Mode come fill up reinforcing backbreak part, locally fall block and base expanding and base expanding face, it is ensured that the complete and base expanding and base expanding of the geometry in base expanding and base expanding face
Stablizing for face, is the technology of the stable offer science in severely-weathered easy disintegrating sandstone place hand excavation's base expanding and base expanding face.
Description of the drawings
Using accompanying drawing, the invention will be further described, but the embodiment in accompanying drawing does not constitute any limit to the present invention
System, for one of ordinary skill in the art, on the premise of not paying creative work, can be being obtained according to the following drawings
Other accompanying drawings.
Fig. 1 is severely-weathered easy disintegrating sandstone place base expanding and base expanding structural excavation schematic diagram.
Reference：
Right cylinder section 1, base expanding and base expanding section 2.
Specific embodiment
The invention will be further described with the following Examples.
A kind of easy disintegrating sandstone place base expanding and base expanding structure as shown in Figure 1, including right cylinder section 1 and base expanding and base expanding section 2, right cylinder section 1
In the center of base expanding and base expanding structure, it is straight column structure.The base expanding and base expanding section 2 by right cylinder section 1 bottom according to design geometries
Excavate to be formed to surrounding, the inner surface of base expanding and base expanding section 2 is referred to as base expanding and base expanding face, is coated with adding Concrete accelerator and glass fibers on base expanding and base expanding face
The cement mortar of dimension, beyond 2 design geometries of base expanding and base expanding section backbreak part and local fall block by adding Concrete accelerator and
The cement mortar of glass fibre is filled up (in engineering construction, often cannot once be formed the geometry of needs, typically have
Certain amount of backbreaking, the part of backbreaking is for the part in the digging process of base expanding and base expanding section beyond design geometries).
The guard method in the base expanding and base expanding face of the sandstone place base expanding and base expanding structure is as follows：Using manual method by severely-weathered easy disintegrating sand
The right cylinder section 1 of rock place base expanding and base expanding structure is dug and is shaped, and according to the design geometries of base expanding and base expanding section 2, is manually opened using pickax
Base expanding and base expanding section 2 is dug, block is fallen to backbreak part and the local that occur in 2 digging process of base expanding and base expanding section, using adding Concrete accelerator and glass
The cement mortar of glass fiber is filled up, so that the geometry in base expanding and base expanding face reaches design requirement, wherein, during the rapid hardening of accelerator
Between control in 20 minutes, the volume of glass fibre occurs without block to guarantee the mortar being attached on sandstone under Gravitative Loads
It is advisable, specifically, rapid hardening time and glass fibre volume are determined according to field experimentation, are fallen 10 points after block fills up end in local
Clock, manually smears the cement mortar of the thick adding Concrete accelerators of 2cm and glass fibre to the entirety in the base expanding and base expanding face of base expanding and base expanding section 2,
Enter a disintegrate slump with prevent severely-weathered easy disintegrating sandstone, it is ensured that base expanding and base expanding face is stable.
Finally it should be noted that above example is only in order to illustrating technical scheme, rather than to present invention guarantor
The restriction of shield scope, although having made to explain to the present invention with reference to preferred embodiment, one of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention
Matter and scope.
