Abstract
The utility model belongs to the field of foundation engineering of power transmission lines, in particular to a spiral-anchor plate type composite foundation. The spiral-anchor plate type composite foundation comprises a plate type foundation and a spiral anchor, wherein the plate type foundation comprises a bottom plate and a stand column, and the spiral anchor comprises anchor rods and spiral anchor sheets. The spiral anchor is arranged at the bottom of the plate type foundation, and the upper part of the anchor rods extend into the bottom plate so that the spiral anchor is fixedly connected with the plate type foundation. The spiral-anchor plate type composite foundation has the characteristics of the plate type foundation and a spiral-anchor foundation. Due to the existing of the spiral anchors of the lower part, the size of the burial depth of the plate type foundation of the upper part is reduced, the earthwork excavated volume is reduced, and the working strength is reduced. Due to the combined action of the plate type foundation of the upper part, the spiral-anchor plate type composite foundation has good resistance to capsizing (namely, the combined action of vertical load and horizontal load) and is suitable for the environment of power transmission lines needing to bear large vertical load and horizontal load.
Description
Technical field
The utility model belongs to the Foundation Design field of transmission line of electricity, is specifically related to the board-like composite foundation of a kind of Screw Anchor.
Background technology
In recent years, the beginning of Screw Anchor basis is used in the transmission line of electricity Foundation Design, and is as shown in Figure 1; The essential structure of Screw Anchor mainly is made up of anchor pole 1 and screw anchor sheet 2; Axial direction along anchor pole 1 evenly is welded with some screw anchor sheets 2, Screw Anchor is pierced in the soil body along arrow indication torsion direction among Fig. 1 through the Screw Anchor rig, along with constantly piercing of anchor pole 1; Screw anchor sheet 2 also embeds surrounding soil, so the Screw Anchor basis has resistance to plucking and resistance to compression bearing capacity preferably.
In the transmission line of electricity Foundation Design; Often need bear bigger vertical and horizontal loading simultaneously, and the transmission line of electricity Foundation Design often transportation condition is not convenient, large-scale construction equipment can't get into; Therefore be applied to the bolt diameter generally less (can adopt small-sized machine to pierce) on the Screw Anchor basis of transmission line of electricity Foundation Design; It bears the ability weak (being that resistance to capsizing is weak) of vertical and horizontal loading simultaneously, and when needs bore very big vertical and horizontal loading, a large amount of Screw Anchor of often need constructing formed large-scale crowd anchor foundation and bears load; Costly, and foundation structure is extremely unreasonable.
Therefore, exigence those skilled in the art develop a foundation structure with better resistance to capsizing.
The utility model content
In order to overcome the above-mentioned defective of prior art, the purpose of the utility model is to propose the board-like composite foundation of the strong Screw Anchor of a kind of resistance to capsizing.
The board-like composite foundation of a kind of Screw Anchor; It comprises slab foundation and Screw Anchor; Said slab foundation comprises base plate and column; Said Screw Anchor comprises anchor pole and screw anchor sheet, it is characterized in that: said Screw Anchor places the bottom of slab foundation, and the top of said anchor pole extend in the base plate Screw Anchor and slab foundation Joint.
Wherein, the quantity of said Screw Anchor is at least two, and the anchor pole top of said Screw Anchor extend in the base plate, and is evenly distributed with the screw anchor sheet along the axial direction of anchor pole.
Wherein, said base plate and column are by arrangement of reinforcement and concreting moulding.
Wherein, the vertical section of said base plate is a rectangle, trapezoidal or stepped.
Wherein, the cross section of said column is circular or square.
The beneficial effect of the utility model is:
1) the board-like composite foundation of this Screw Anchor has the characteristics on slab foundation and Screw Anchor basis concurrently, and both are combined effectively.Compare with independent slab foundation,, reduce earthwork excavated volume, reduce working strength because the existence of Screw Anchor reduces board-like key dimension in top and buried depth;
2) compare with Screw Anchor crowd anchor foundation; Because the acting in conjunction of top slab foundation; Make the board-like composite foundation of Screw Anchor have better resistance to capsizing (being vertical load+horizontal loading acting in conjunction), more be applicable in the transmission line of electricity environment that need bear vertically big and horizontal loading.

The specific embodiment
Below in conjunction with accompanying drawing the board-like composite foundation of the Screw Anchor of the utility model is done further detailed explanation.
As shown in Figure 2; The composite foundation of the utility model comprises top slab foundation and bottom Screw Anchor, and Screw Anchor mainly is made up of anchor pole 1 and screw anchor sheet 2, and slab foundation mainly is made up of base plate 3 and column 4; Screw Anchor places the bottom of slab foundation; The anchor pole 1 of Screw Anchor is extend in the base plate 3 of slab foundation, make slab foundation and Screw Anchor acting in conjunction, form the board-like composite foundation of Screw Anchor.
The quantity of Screw Anchor is at least two, and is as shown in Figure 3, adopts four Screw Anchor to insert in the base plate 3 in this example, and anchor pole 1 top of Screw Anchor extend in the base plate, and is evenly distributed with screw anchor sheet 2 along the axial direction of anchor pole.The base plate 3 of slab foundation and column 4 are by arrangement of reinforcement and concreting moulding, and the vertical section of base plate is a rectangle, trapezoidal or stepped, and the cross section of column is circular or square.
The concrete work progress of this composite foundation is following:
1, with the Screw Anchor rig four Screw Anchor is pierced respective depth in the soil body earlier;
2, the foundation ditch 8 of excavation top slab foundation by a size slab foundation size supporting template of actual requirement of engineering, is put into arrangement of reinforcement 5 then in the template of slab foundation;
3, anchor pole 1 top with Screw Anchor extend in the base plate 3 of slab foundation;
4, then, fluid concrete in the template of slab foundation is integral the arrangement of reinforcement 5 of concrete 6, slab foundation, Screw Anchor gluing, forms the board-like composite foundation of Screw Anchor;
5, the template of dismounting slab foundation, backfill surrounding soil 7, the board-like composite foundation of final Screw Anchor is as shown in Figure 4.
The utility model is with Screw Anchor basis and slab foundation compound action; Form the board-like composite foundation of Screw Anchor; Compare with the Screw Anchor basis, have better resistance to capsizing, be mainly used in the transmission line of electricity Foundation Design that to bear vertically big and horizontal loading.
Should be noted that at last: above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; Although the utility model has been carried out detailed explanation with reference to the foregoing description; Under the those of ordinary skill in field be to be understood that: still can make amendment or be equal to replacement the specific embodiment of the utility model; And do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of the claim scope of the utility model.
