Abstract
It the utility model is related to and belong to transformer station's structure, support rim of a cup basic technology field, it is in the case where geological conditions is poor, efficiency of construction can be improved using high-cup foundation, ensure that construction quality, base concrete amount has been saved simultaneously, it is more reasonable in terms of stress.The high rim of a cup concrete foundation, it is included in below ground and is provided with the basic hole being embedded in for embedded foundation, basis is in basic hole, and concrete is filled between basic hole wall basic, middle position is default on the basis of described or is machined with steelframe embedded hole, the steelframe embedded hole upper end oral area frontal projected area is less than rim of a cup bottom frontal projected area, and steel or concrete frame lower end are embedded in steelframe embedded hole center in advance, and embedding has concrete in the gap between framework and steelframe embedded hole inwall.Compared with traditional rim of a cup basis, easy for construction, reliable in quality, reasonable stress, saving construction cost.
Description
Technical field
The utility model belongs to transformer station's structure, support rim of a cup basic technology field, more particularly to a kind of high rim of a cup concrete
Basis.
Background technology
As shown in figure 1, transformer station's structure, bracket basis generally use concrete rim of a cup basis, usual bracket basis bury at present
Deep 1.2m, framework embedded depth of foundation 2.0m, if to run into local geology poor on basis, basic ultra-deep typically uses cemented rock or hair
Stone concrete, which changes, to be filled out.
Above-mentioned traditional main transformer foundation weaknesses analysis are as follows：
1. ground changes when filling out deeper, soil removal enginnering amount is big, uneconomical（The bottom of foundation is more big more uneconomical）.
2. difficulty of construction is big（Building block stone）, low construction efficiency, quality is difficult to control.
3. basis is by uplift force, in order to resist uplift force, increase basis deadweight, base concrete dosage is higher.
Utility model content
The purpose of this utility model is in the case where geological conditions is poor, and construction effect can be improved using high-cup foundation
Rate, construction quality is ensure that, while saved base concrete amount, it is more reasonable in terms of stress.
To achieve these goals, technical solution adopted in the utility model is：
A kind of high rim of a cup concrete foundation, it is included in below ground and is provided with the basic hole being embedded in for embedded foundation, basis
Concrete is filled between basic hole wall in basic hole, and basic, on the basis of described middle position it is default or
Steelframe embedded hole is machined with, the steelframe embedded hole upper end oral area frontal projected area is less than rim of a cup bottom frontal projected area, steel or mixed
Coagulate native framework lower end be embedded in advance steelframe embedded hole center, and in the gap between framework and steelframe embedded hole inwall embedding have it is mixed
Solidifying soil.
Under the foundation blinding layer is provided between end and basic bottom hole portion.
Described steelframe embedded hole is in integrally the truncated cone-shaped structure of hollow out, and steelframe embedded hole port part is gradual to base diameter
Increase.
Described basis is that prefabricated or cast in situs forms.
Described blinding layer is that cemented rock material is paved into.
The beneficial effects of the utility model：The utility model has advantages below compared with traditional rim of a cup basis：
1. high-cup foundation can effectively solve the problems, such as basic ultra-deep, with traditional method（Change to fill out in rim of a cup ground beneath and grout
Block stone or cyclopean concrete）Compare, reliable construction quality, efficiency high, save construction costs.
2. high-cup foundation uses interior domatic rim of a cup（It is exactly steelframe embedded hole mentioned herein）, with traditional method（Outer slope
Shape）Compare, rim of a cup is connected relatively reliable with support（Especially in resistance to plucking, interior domatic rim of a cup breakout capacity is stronger, more reliable）.
3. for high-cup foundation compared with traditional rim of a cup basis, high-cup foundation is big with soil contact, basic stress is more
Rationally（Pass through side friction and vertical supporting）, in the case of especially being pulled out on basis, high-cup foundation mainly by basis with
The friction and deadweight of soil carry out balanced basis uplift force.And traditional rim of a cup basis is mainly by conducting oneself with dignity come on balanced basis
Pull out force.
Brief description of the drawings
Fig. 1 is the structural representation of background technology；
Fig. 2 is structural representation of the present utility model.
Embodiment
The utility model is described further with reference to embodiment.
Embodiment
A kind of high rim of a cup concrete foundation as shown in Figure 2, it is included in below ground and is provided with for embedded foundation insertion
Basic hole 1, basis 2 are filled with concrete in the basic hole basic between basic hole wall, on the basis of described in
Centre position is default or is machined with steelframe embedded hole 3, and the steelframe embedded hole upper end oral area frontal projected area is just thrown less than rim of a cup bottom
Shadow area, steel or the lower end of concrete frame 4 are embedded in steelframe embedded hole center in advance, and between framework and steelframe embedded hole inwall
Embedding has concrete in gap.Under the foundation blinding layer 5 is provided between end and basic bottom hole portion.Described steelframe embedded hole is whole
Body is in the truncated cone-shaped structure of hollow out, and steelframe embedded hole port part to base diameter gradually increases.Described basis is prefabricated or existing
Field, which pours, to be formed.Described blinding layer is that cemented rock material is paved into.
The purpose of this utility model is in the case where geological conditions is poor, and construction effect can be improved using high-cup foundation
Rate, ensure that construction quality, while saved base concrete amount, in terms of stress more rationally, be mainly reflected in basis with
Support connection use Inner domatic rims of a cup, on the other hand when basis is pulled out, high-cup foundation mainly by compared with higher baseline length and
Soil body friction balances uplift force, and traditional rim of a cup basis is mainly by conducting oneself with dignity come balanced basis uplift force.
The construction method of high rim of a cup concrete foundation in the present embodiment：
1. according to basic section borehole；
2. pour bed course；
3. pour high-cup foundation and reserved interior domatic rim of a cup；
4. support or framework are inserted into rim of a cup, back-grouting.
The utility model is realized under geology poor condition, and effectively solving basic ultra-deep using high-cup foundation form asks
Topic, and compared with traditional rim of a cup basis, reliable construction quality, reasonable stress, saving construction cost.The utility model is skillfully constructed,
In the case where geology is poor, effectively solves the problems, such as structure bracket basis ultra-deep.Compared with traditional rim of a cup basis, construction party
Just, reliable in quality, reasonable stress, saving construction cost.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
