Abstract
The utility model discloses a kind of anchor pole drawing-type concrete retaining wall structure, comprise concrete retaining wall (1) and side slope (5), side slope (5) is provided with anchor pole (2), anchor pole (2) anchors into 2 ~ 5m in side slope (5), be embedded with lacing wire (3) in concrete retaining wall (1), described lacing wire (3) is connected by the termination of exposing of sleeve (4) with described anchor pole (2).The utility model can effectively improve retaining wall antiskid and stability against overturning by anchor pole tractive structure, and meanwhile, anchor pole, through the wall back of the body backfill soil body, improves backfill soil body angle of internal friction and improves soil body skid resistance.The utility model construction technology is simple, and construction difficulty is less, and security risk is little, invests less, improves the security and stability of traffic engineering cliff place retaining wall effectively.
Description
Technical field
The utility model relates to a kind of retaining wall structure, and especially a kind of highway subgrade anchor pole drawing-type concrete retaining wall structure of cliff place, belongs to traffic engineering embankment slope retaining technical field.
Background technology
At present, in the supporting of traffic engineering embankment slope earth-retaining wall, when traffic route is through steep cliff cliff, generally take following measures: 1, take excavation slope to form roadbed, it is very high that it forms Highway Slope Excavation height, and difficulty of construction is very big, and security risk is large.When taking cut and fill side's roadbed, retaining wall height is very high, if take concrete frame beam structure to form foundation of road bed, but frame beam structure requires high to foundation bearing capacity, structure construction complex procedures, and construction speed is slow; 2, take cut and fill or retaining wall is set completely, wall back of the body backfill rock ballast is to form highway subgrade, because the cliff place gradient is precipitous, cause retaining wall height very high, retaining wall runtime stability is difficult to ensure, security risk is very big, often causes severe traffic accidents because retaining wall unstability collapses, causes heavy losses to human life and property; 3, take the pattern of arranging tunnel, construction of tunnel technical difficulty is large, and security risk is large, and investment is large, and the traffic driving visual field is open not.Therefore, existing traffic engineering embankment slope earth-retaining wall supporting measure or not ideal enough, awaits perfect further.
Utility model content
The purpose of this utility model is to provide a kind of anchor pole drawing-type concrete retaining wall structure, improves skid resistance and the concrete retaining wall structural safety ultimate carrying capacity of the cliff place retaining wall back of the body backfill soil body, to overcome the deficiencies in the prior art.
The technical solution of the utility model is such:
The utility model is a kind of anchor pole drawing-type concrete retaining wall structure, it comprises concrete retaining wall and side slope, side slope is provided with anchor pole, anchor pole anchors into 2 ~ 5m in side slope, wherein be embedded with lacing wire in this concrete retaining wall, lacing wire is connected by sleeve with the termination of exposing of described anchor pole thus forms tractive structure by concrete retaining wall and side slope tractive.Horizontal or the blossom type shape of lacing wire is embedded in concrete retaining wall, certainly, the position of lacing wire on retaining wall should be corresponding with the position of anchor pole in side slope, makes an anchor pole on every root lacing wire and relevant position can be connected to form tractive structure one by one.The arrangement pitch of lacing wire on retaining wall is consistent with anchor pole, is generally 1 ~ 2.5m.One end that lacing wire is exposed outside concrete retaining wall is connected with one end that anchor pole exposes side slope.For guaranteeing that lacing wire and anchor pole better link together, adopt sleeve by the two effective bind.
Sleeve all can firmly must be connected with lacing wire and anchor pole, therefore reasonable method is threaded, such sleeve is provided with internal thread, the termination that lacing wire and anchor pole are connected to each other is equipped with the external screw thread mated with described internal thread to be all threaded with described sleeve to make lacing wire and anchor pole, the advantage be threaded is to connect reliably, and installation and removal fast and easy.
Further, anchor pole is provided with sleeve pipe, sleeve pipe is pvc pipe or PE pipe.Adopt casing protection concrete retaining wall run duration anchor pole and the extraneous soil body, moisture to be isolated outward at anchor pole, so as not to because get rusty, the factor such as shelling and reduce and even lose anchor pole traction force, can greatly improve this reliability of structure and application life.In addition, concrete retaining wall lays some drain holes, and the water pressure avoiding the ponding between retaining wall and side slope to bring like this causes retaining wall integral slipping to affect structural safety.
Compared with prior art, the utility model is by arranging anchor pole and lacing wire, and for concrete retaining wall structure provides the pulling force contrary with it, improve antiskid and the stability against overturning of concrete retaining wall, structure is simple, quick construction is convenient, technical security is reliable; By arranging anchor pole, improving the angle of internal friction of the wall back of the body backfill soil body, improving the skid resistance of the backfill soil body, reduce the active earth pressure of the soil body to concrete retaining wall.The utility model structure is simple, constructability, and technical security is reliable, economic and practical, can in traffic engineering embankment slope earth-retaining wall support technology field wide popularization and application.

Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-concrete retaining wall, 2-lacing wire, 3-anchor pole, 4-sleeve, 5-side slope, 6-sleeve pipe.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, concrete retaining wall 1 of the present utility model is arranged at outside side slope 5, concrete retaining wall 1 exposes termination by lacing wire 3 with the anchor pole 2 anchoring into side slope 5 and is connected by sleeve 4, connected mode is for being threaded, such lacing wire 3 forms tractive structure mutually with anchor pole 2, provides certain traction force to concrete retaining wall 1, improves the angle of internal friction of the concrete retaining wall 1 wall back of the body backfill soil body, improve the skid resistance of the backfill soil body, reduce the active earth pressure of the soil body to concrete retaining wall 1.
Sleeve pipe 6 is adopted to protect anchor pole 2; construction technique is simple; sleeve pipe 6 is generally PVC or PE material; not only be easy to buying; invest little; and can preferably anchor pole 2 and the backfill soil body and moisture better be isolated, guarantee anchor pole 2 can not because getting rusty, the factor such as shelling and reduce and even lose traction force, ensure concrete retaining wall 1 safe operation.
As shown in Figure 1, the utility model, when implementing, first buries some lacing wires 3 underground in concrete retaining wall 1, and the horizontal or blossom type shape of lacing wire 3 is arranged, is anchored into by anchor pole 2 in side slope 5, then lacing wire 3 is connected by some sleeves 4 with anchor pole 2.The utility model structure is simple, quick construction convenient, technical security is reliable; Adopt sleeve pipe 6 to protect anchor pole 2, guarantee anchor pole 2 can not because getting rusty, the factor such as shelling and reduce and even lose traction force, ensure concrete retaining wall 1 safe operation.
More than just embody rule example of the present utility model, the technical scheme that the utility model also has other embodiment, all employings to be equal to replacement or equivalent transformation to be formed, all drops within the protection domain required by the utility model.
