Detailed description of the invention

As Figure 1-Figure 4, a kind of anchor head structure being placed in anchored bolt retaining wall concrete slab, including steel strand wires 1, anchorage 2, billet 3 and trapezoidal pad pier 6；Described trapezoidal pad pier 6 is arranged at the trapezoidal pit of slope body In, described trapezoidal pad pier 6 is the pad pier that concrete 4 pours trapezoidal fabrication of reinforcing cage.Steel strand wires 1 One end is arranged at Ti Nei hole, slope, and the other end stretches out through trapezoidal pad pier 6 center, and described steel strand wires 1 are outside Bag is provided with pvc pipe.

The overlap joint reinforcing bar that described trapezoidal pad pier 6 outer end reserves, is used for the steel of casting concrete panel with outside Muscle net 5 connects, and forms integer support structure, and described bar-mat reinforcement 5 uses double-layer double-direction bar-mat reinforcement.

Described billet 3 is fixed by bolts to, outside trapezoidal pad pier 6, be provided with outside described billet 3 Fitting into line-locked anchorage 2 with steel strand wires 1, described anchorage 2 is arranged at concrete surface intralaminar part, as Supporting body dispersion anchor head pressure.Anchor head structural shape can overcome the shortcoming that conventional support pattern durability is low, Separately anchor head is built-in can reduce the rain drop erosion erosion to anchor head structure, it is to avoid it is unnecessary that pedestrian's climbing causes Danger, adds somewhat to the safety of side slope.

As in figure 2 it is shown, be trapezoidal pad pier 6 and the connection way of concrete slab, figure designates reinforcing bar type Number size and weld size.Wherein should include following requirements:

1, reinforcing bar uses HPB300, HRB335, HRB400 level reinforcing bar, and the arrangement of reinforcement of trapezoidal pad pier 6 should meet Code requirement.

2, figure does not shows anchorage length of steel bar HRB400 reinforcing bar La=40d (d is steel bar stress diameter).

3, bar splicing require: the lap of splice be 1.4La, La be 35d (d is bar diameter), same section Face bar splicing area must not exceed 50%.

4, reinforcement welding requires: steel bar stress should use welding.Between one-level reinforcing bar, welding uses E43 series Welding rod, between grade III steel muscle, welding uses E50 series welding rod, welding rod length: single welding 10d, welding by both sides 5d (d is bar diameter).Same cross section reinforcing bar bonding area must not exceed 50%.

As it can be seen, the construction method of a kind of anchor head structure, including following construction procedure:

(1) as it is shown in figure 5, after slope body specifies position boring, put into steel strand wires 1, carry out slip casting operation；

(2), domatic centered by bore position, the trapezoidal pit of excavation specified size, size and trapezoidal pad Pier 6 size adapts, in case placing trapezoidal pad pier 6.

(3), as shown in Figure 6, scene carries out the fabrication of reinforcing cage of trapezoidal pad pier 6 and the concrete 4 of correspondence Pour；When the making of steel reinforcement cage, should reserve and the overlap joint reinforcing bar of anchor pole slab reinforcement net 5, concrete 4 When pouring, during concreting, with pvc pipe 7, steel strand wires 1 are encased, along the trapezoidal pad pier 6 in pouring Center pass.Described trapezoidal pad pier 6 is close on the pit wall that slope wall is reserved, due to angle obliquely, Make combine stronger with side slope of trapezoidal pad pier 6, form one.

(4) as it is shown in fig. 7, after pad pier concrete 4 after to be solidified reaches prescribed strength, place thereon Billet 3, carries out prestressed stretch-draw, and locks with anchorage 2；

(5), as shown in Figure 8, at domatic laying anchor pole slab reinforcement net 5, complete to pad pier reserved steel bar and face The overlap joint of plate bar-mat reinforcement 5；

(6), finally carry out pouring of anchor pole panel concrete 4, branching standing template, pour mixed by design requirement Solidifying soil 4, makes anchorage 2 be arranged at the concrete surface intralaminar part poured；Concrete 4 pour deviation not More than 20mm.

(7), repeat the above steps, until having constructed, then carry out the work of greening side slope.

The trapezoidal pit size dug out in step (2) adapts with trapezoidal pad pier 6 size.

In this utility model to be solidified after pad pier concrete reach prescribed strength after, place billet thereon, Carry out prestressed stretch-draw, and lock with anchorage, use prestress steel strand reinforced side slope to have more apparent Security advantages, construction safety is convenient.

The anchor head structure being placed in anchored bolt retaining wall concrete slab described in the utility model, relate to civil building, Water conservancy and hydropower, highway, railway construction engineering etc. are for slope retaining field, it is desirable to provide meet durability Require permanent anchor head structure and construction method thereof.

The anchor head structure being placed in anchored bolt retaining wall concrete slab described in the utility model, it is possible to for every Among the conventional side slope of engineering, anchor head pattern surfacing is succinct, promotes the overall appearance degree of environment, this Advantage is especially prominent in the modern times day by day focusing on greening factor.

The anchor head structure being placed in anchored bolt retaining wall concrete slab described in the utility model, anchor head is built-in can Reduce the impact of natural cause to greatest extent, thus increase the safety of anchor structure.Additionally use anchor pole Barricade carries out that the example that anchors is long to be seen, it is therefore necessary to the anchor head structure in anchored bolt retaining wall and construction thereof Method is optimized design, provides reference and reference for the design of later similar engineering.
