Abstract
The utility model discloses a horizontal return bend anchor block of convex key -wall formula, including the anchor block main part of cladding at horizontal return bend outer peripheral face, the anchor block main part comprises fan -shaped section and first straightway and the second straightway that links up in fan -shaped section both sides, the radian of fan -shaped section equals with the radian of horizontal return bend meander that the bottom of anchor block main part is two hierarchic structures, is provided with the plain concrete bed course at the bottom surface of anchor block main part. The utility model discloses it is more reasonable that the advantage mainly embodies at the anchor block structure size, saves the concrete quantity, anchor block main part excavation volume is smaller, in the limited piped water supply engineering in specially adapted excavation space, the anchor block main part adopts optimalarc formula and parallel with the central pitch arc of pipeline, has improved anchor block main part stability against sliding, the anti thrust of anchor block main part side (bottom) is two hierarchic structures, and it lands to show has improved the antidumping ability of anchor block main part, can be applicable to large -traffic, big pipe diameters more and more at present, multi -channel's water supply pipe engineering.
Description
Technical field
The utility model relates to pipeline water supply and sewage engineering field, especially relates to the round-arced tooth wall-side bend anchor block being applicable to horizontal pipe turning.
Background technique
Along with the continuous quickening of Development of China's Urbanization, cities and towns increase severely to the demand of water, and pipeline water supply and sewage engineering becomes the important leverage that cities and towns run well.Side bend anchor block is common in pipeline water-supply engineering and very important structure, generally side bend anchor block is arranged in pipeline plane turning place, to bear the imbalance thrust force that pipeline changes the water pressure generation of direction place, very important effect is played to the safe operation of pipeline.Along with the increasing of town water supply water consumption, the caliber of pipeline increases gradually, is expanded to the caliber of more than DN3000 by original pipe with small pipe diameter, and pipeline also has original one-pipe to become twin flue even three pipelines.Therefore, traditional side bend anchor block size and structural type, can not meet existing piped water supply ability.Conventional flat bend pipe anchor block has following deficiency: 1, size is bigger than normal, and concrete amount is large, uneconomical; 2, excavated volume and excavation space are greatly, and particularly town water supply excavation is restricted; 3, stress condition is single, side bend anchor block or dependence earth pressure, or resists hydrodynamic thrust by the deadweight of side bend anchor block, is difficult to meet large discharge, Large Diameter Pipeline water supply project.
Summary of the invention
The utility model object is to provide a kind of round-arced tooth wall-side bend anchor block going for one-pipe, twin flue and three pipelines.
For achieving the above object, the utility model takes following technical proposals:
Round-arced tooth wall-side bend anchor block described in the utility model, comprises the anchor block main body being coated on side bend outer circumferential face, and described anchor block main body is made up of fan-shaped section and the first straightway be connected in described fan-shaped section both sides and the second straightway; The radian of fan-shaped section is equal with the radian in side bend bending part, and the bottom of anchor block main body is two hierarchic structures, and the lower surface of anchor block main body is provided with plain concrete cushion layer.
Reinforcing mesh is furnished with in described anchor block body surfaces.
The utility model advantage major embodiment is in the following areas:
1, anchor block physical dimension is relatively more reasonable, saves concrete amount, both economical;
2, anchor block main body excavated volume is smaller, is specially adapted to excavate in the pipeline water-supply engineering of limited space;
3, anchor block main body adopts form of arcs and parallel with pipe center camber line, increase the anti-thrust sides of anchor block main body and soil body area of contact, thus increase passive earth pressure, reduce active earth pressure, anchor block main body stability against sliding will be substantially increased, thus improve its Security;
4, the anti-thrust sides of anchor block main body (bottom) is two hierarchic structures, increases the sliding resistance of anchor block main body.Arrange rational two step size anchor block main body not only can be impelled to keep balance but also the resistance to capsizing of anchor block main body can be improved significantly;
5, anchor block main body peripheral side can arrange reinforcing mesh, improves the tensile strength of anchor block main body weak part and the stressed integrity of anchor block with this;
6, the water supply line engineering of increasing large discharge, Large Diameter Pipeline, multi-pipeline at present can be applicable to.

Fig. 1 is plane arrangement structure schematic diagram of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional drawing.
Fig. 3 is stereochemical structure reference drawing of the present utility model.
Embodiment
As Figure 1-3, round-arced tooth wall-side bend anchor block described in the utility model, comprise the anchor block main body being coated on side bend 1 periphery, anchor block main body is made up of fan-shaped section 2 and the first straightway 3 be connected in described fan-shaped section 2 both sides and the second straightway 4, this can not only save concrete amount, the area of contact of the anti-thrust sides of anchor block main body and the soil body can also be increased, and then increase earth pressure, improve Security; The radian of fan-shaped section 2 is equal with the radian in side bend 1 bending part.Two hierarchic structures are arranged in the bottom of anchor block main body, extend anchor block main body external wall area, obviously can increase the sliding resistance of anchor block main body, improve the resistance to capsizing of anchor block main body; The lower surface of anchor block main body is provided with plain concrete cushion layer 5.When anchor block size of main body is larger, reinforcing mesh can be arranged in anchor block body surfaces, to improve the tensile strength capacity of anchor block main body weak part and stressed integrity.
Claims (2)
