Abstract
The utility model relates to an excavated spread pole and tower foundation of a side wing plate, which comprises a foundation main body and a side wing plate 3, wherein the foundation main body comprises a foundation upright post 1 and an under reaming end 2 which are mutually connected, and the side wing plate 3 is connected with the side surface of the foundation upright post 1. The excavated spread pole and tower foundation of the side wing plate is beneficial to increasing the horizontal bearing capacity of the foundation and can enhance the antidumping stability of the foundation buried in a base, thereby being the first choice in the future line foundation application field.
Description
Technical field
The utility model relates to the electric power line pole tower basic field, particularly relates to a kind of side wing pottery and digs expansion bottom bar column foot plinth.
Background technology
Along with development economic and society; the transmission line of electricity grade is more and more higher; horizontal loading that line tower foundation bears and vertical load are also increasing; and environmental protection is also had higher requirement; therefore; under the requirement of new situations and Geng Gao, the pottery that in geological environments such as clay, silt, weathered rock formation, makes full use of the undisturbed soil bearer properties dig spread foundation be the transmission line of electricity basis preferably situation select.But in the part geological environment, the relative vertical bearing capacity of horizontal bearing capacity that digs spread foundation according to the pottery of usual conditions designs is less, and under big loading condition, if make full use of vertical bearing capacity, possible horizontal bearing capacity is deficiency just; Make full use of horizontal bearing capacity if strengthen key dimension, possible vertical bearing capacity safety factor is more much bigger than required safety stock.Therefore, exigence is developed a not only economy but also practical pottery digs spread foundation.
The utility model content
In order to overcome the defective of prior art, the purpose of this utility model is to provide a kind of side wing that improves foundation bearing capacity and stability to make pottery and digs and expands bottom bar column foot plinth.
For this reason, the utility model proposes a kind of side wing pottery and dig expansion bottom bar column foot plinth, comprise basic main body and side wing, described basic main body comprises interconnective basic column and bottom bellend, and described side wing is connected with the side of basic column.
Wherein, described side wing is in-line or cross layout.
Wherein, the thickness of described side wing is 40cm-100cm.
Wherein, described side wing is formed by cage of reinforcement and concreting.
Wherein, described side wing and basic column are affixed by steel concrete.
Wherein, described basic main body is formed by cage of reinforcement and concreting.
The beneficial effects of the utility model are: this side wing pottery digs expansion bottom bar column foot plinth and may be used in the geological environment of clay, silt, weathered rock formation, by the bottom bellend is set, can increase the contact area of basis and foundation level direction; By side wing is set, can improve the side direction bearing area on basis, make the basis when making full use of advantages such as the high distortion of undisturbed soil bearing capacity is little, change, improve its horizontal bearing capacity and stability against overturning.
Description of drawings
Fig. 1 makes pottery for side wing described in the utility model and digs the structural representation that expands bottom bar column foot plinth;
Fig. 2 is the connection diagram of side wing and basic column;
Fig. 3 is the connection diagram of another embodiment of side wing and basic column;
Wherein, 1-basis column, 2-bottom bellend, 3-side wing, 4, the 31-cage of reinforcement, 5, the 32-concrete.
The specific embodiment
Below in conjunction with accompanying drawing side wing pottery of the present utility model is dug expansion bottom bar column foot plinth and be described in further detail book.
As shown in Figure 1, 2, this routine described side wing pottery digs expansion bottom bar column foot plinth and comprises basic main body and side wing 3, described basic main body is the lower end basic column 1 that is provided with bottom bellend 2, it is built by cage of reinforcement 4 and concrete 5 and form, described side wing 3 by cage of reinforcement 31 and concrete 32 build form, it is on the opposite flank that in-line is distributed in basic column 1 and affixed by steel concrete and basic column 1, the thickness of side wing 3 is good with 40cm-100cm.
Concrete job practices is: the heatable adobe sleeping platform that 1, carries out basic column 1 and bottom bellend 2 is drawn and is dug; 2, the heatable adobe sleeping platform that carries out side wing 3 is drawn and is dug, its draw dig the degree of depth from the face of land to the side wing bottom degree of depth; 3, assembling reinforcement; 4, prop up template, formwork comprises partly appearing in the basis, wing plate top and wing plate top institute excavation column sidewall; 5, concreting wherein, is built to the side wing top design degree of depth, and promptly the backfill foundation soil is built all the other concrete again.
Side wing pottery described in the utility model digs expansion bottom bar column foot plinth and had both helped improving the horizontal bearing capacity on basis, can improve the stability against overturning of imbedding basis in the ground again, is the first-selection in the following line tower foundation application.
Embodiment 2
This routine described side wing is made pottery and is dug the structure that expands bottom bar column foot plinth and job practices substantially with embodiment 1, has different being only, and as shown in Figure 3, side wing 3 is on the side that cross-shaped symmetrical is distributed in basic column 1.
Invention has been described according to specific exemplary embodiment herein.It will be conspicuous carrying out suitable replacement to one skilled in the art or revise under not departing from the scope of the present invention.Exemplary embodiment only is illustrative, rather than to the restriction of scope of the present invention, scope of the present invention is by appended claim definition.
