Abstract
The invention discloses a fast prestress anchor stock structure. The structure is characterized by comprising a pedestal (1) arranged on one lateral side of a waist rail (4); a drill (5) penetrates through the waist rail (4) and enters a supporting body on the other lateral side of the waist rail (4); an anchoring reinforcement (2) penetrates through the pedestal (1) and is arranged in the drill (5), and a plurality of barbs (6) are arranged at the inner section of the anchoring reinforcement (2); a bearing plate (3) is arranged at the outer end of the anchoring reinforcement (2), and grout (7) is arranged in the drill (5) and around the anchoring reinforcement (2). Additionally, the invention further provides a construction method for the prestress anchor stock structure. According to the structure and the method, the structural design is reasonable, the application range is wide, the contact area of the pile foundation with surrounding soil layers can be obviously increased on the premise that the pile length and the cross section area are not changed, a large prestress can be exerted, the construction time can be reduced greatly, and the construction period is shortened.
Description
Technical field
The present invention relates to a kind of concrete anchor rod that is widely used in the various basic loads such as construction work, bridge engineering, municipal engineering, hydraulic engineering, specifically relate to structure and the construction technology of novel anchor pole, be specially adapted to the unstable situation that needs reinforcement in a hurry and process of side slope.
Background technology
Prestress anchoraging is a kind of measure that increases retaining structure or stability of rock-soil body with anchoring process.Its method is that drilling passes the slide plane that might slide or slided, one end of reinforcing bar (or cable wire) is fixed in the stable Rock And Soil at the bottom of the hole, reinforcing bar (or cable wire) is strained so that can produce certain screen resilience (being prestressing force) again, then the other end with reinforcing bar (rope) is fixed in Rock And Soil or retaining structure surface, utilizing the screen resilience of reinforcing bar to compress can slidable Rock And Soil or retaining structure, with the shear strength on the increase slide plane, thereby reach the purpose that improves Rock And Soil or retaining structure stability.
In the process of prestressed anchor construction, because the adhesion stress between reinforcing bar and the grouting body just can be carried out stretch-draw when reaching certain value, need the time more than 7 days in the general process, the stand-by period is longer.
Summary of the invention
The objective of the invention is to have overcome the deficiencies such as prestressed anchor construction period length of the prior art, complex procedures, proposed that a kind of engineering time section, frictional resistance are large, structure and the job practices of the quick prestressed anchor of good stability, but in extensive use and the building hydraulic engineering.
The technical solution used in the present invention is as follows:
A kind of quick prestressed anchor structure, it is characterized in that it includes pedestal, anchor bar, bearing plate, waist rail and boring, described pedestal is installed on the side of waist rail, the supporter that waist rail enters into the another side of waist rail is passed in boring, anchor bar passes pedestal and is installed in the boring, inner section of anchor bar is provided with many hangnails, in the outer end of anchor bar bearing plate is installed, in the described boring anchor bar around be provided with the grouting body.
Described hangnail is for being welded on the anchor bar, and the hangnail structure is flakey, and direction is outside towards anchor pole.
The present invention also provides a kind of job practices that adopts above-mentioned quick prestressed anchor structure, it is characterized in that concrete steps are:
(1) at first needs to calculate the pre-fixed pile of stake, then adopt various suitable boring methods to get out the native hole of projected depth in predetermined stake position;
(2) boring complete after, anchor bar is squeezed in the boring;
(3) after anchor bar is got to the precalculated position, the stretch-draw anchor reinforcing bar embeds in the rock of the soil body hangnail on the anchor bar on every side;
(4) in boring, pour into mixed earth packing material, form the grouting body anchor bar (2) is more intactly bondd with surrounding soil by mixing earth;
(5) carry out the waist rail construction, according to designing requirement size excavation pedestal foundation trench, will reserve again the hole that pedestal is put in good anchor bar end, then load onto bearing plate in the anchor bar end;
(6) the stretch-draw anchor reinforcing bar reaches predetermined power, and the unnecessary exposed steel bar of pruning;
(7) sealing off and covering anchorage, construction finishes.
Compared with prior art, the invention has the beneficial effects as follows:
Reasonable in design, applied range, can be under the prerequisite that does not change pile length and section area, increase significantly pile foundation and the contact area between the soil layer on every side, can apply larger prestressing force, adopt rational technology and construction technology, can greatly reduce the engineering time, so just can make the speed of application of prestressed anchor obtain larger performance, reduce the duration.
Description of drawings
Fig. 1 is the overall structure schematic diagram of prestressed anchor structure of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing with further specify embodiments of the present invention.
As shown in Figure 1, prestressed anchor structure of the present invention includes pedestal 1, anchor bar 2, bearing plate 3, waist rail 4 and holes 5, described pedestal 1 is installed on the side of waist rail 4, the supporter that waist rail 4 enters into the another side of waist rail 4 is passed in boring 5, and anchor bar 2 passes pedestal 1 and is installed in the boring 5.2 inner sections of anchor bars are provided with many hangnails 6, and hangnail 6 is to be welded on the anchor bar 2, and hangnail 6 structures can be flakey, and direction is outside towards anchor pole.In the outer end of anchor bar 2 bearing plate 3 is installed, the grouting body 7 that forms for concrete around the 5 interior anchor bars 2 of holing.
Step during Specific construction is as follows:
(1) at first needs to calculate the pre-fixed pile of stake, then adopt various suitable boring methods to get out the native hole of projected depth in predetermined stake position, as adopting augers, the first-class boring method of Churn drill;
(2) boring complete after, with anchor bar 2 squeeze into boring 5 in;
(3) after anchor bar 2 is got to the precalculated position, stretch-draw anchor reinforcing bar 2 embeds in the rock of the soil body hangnail 6 on the anchor bar 2 on every side;
(4) in boring 5, pour into mixed earth packing material, form grouting body 7 anchor bar 2 is more intactly bondd with surrounding soil by mixing earth;
(5) carry out waist rail 4 constructions, according to designing requirement size excavation pedestal foundation trench, will reserve again the hole that pedestal 1 is put in good anchor bar 2 ends, then load onto bearing plate 3 in anchor bar 2 ends; Fix the template concreting, vibration compacting.
