Abstract
The utility model discloses an embedded slope prestressed anchorage cable anchor pier structure, which comprises an anchor pier groove (2) embedded and formed in a rock at a slope excavation surface (1), wherein anchor pier concrete (3) with a reinforced concrete structure is arranged in the anchor pier groove (2), a reserved anchorage cable hole (4) is drilled in the anchor pier concrete (3), and the reserved anchorage cable hole (4) extends into the rock; an anchor cable component (5) is arranged in the reserved anchor cable hole (4); an anchor cable protection pier (6) formed by pouring concrete is arranged at the exposed end of the anchor cable component (5). Through the utility model discloses make the anchor pier of prestressed anchorage cable do not stand out the excavation face, the face and the excavation face of final formation flush, the structural arrangement in the later stage of being convenient for more.
Description
Technical field
The utility model belongs to slope retaining field, more particularly to the anchor cable pier structure of side slope.
Background technique
Anchor cable is a kind of common slope retaining means in earthwork evacuation engineering, and the anchor pier of general anchor cable is all to excavate
Based on face, the armored concrete platform body structure of prominent excavation face, pier outside places the locking device of anchor cable, and anchor cable is from pier
It is passed through among body, compression can be generated on anchor pier after anchorage cable stretching, the effect of anchor pier is exactly to be homogenized prestressd anchor cable in side slope
Distribution in excavation face, the deformation for avoiding side slope face excessive since compressive pre-stress generates even destroy.
Existing prestress anchorage cable anchor pier is all prominent excavation slope face, if you need to abut excavation face arragement construction, anchor pier
Structure space will be occupied, structure arrangement is influenced.
Utility model content
The purpose of the utility model is to provide a kind of embedded side slope prestress anchorage cable anchor pier structures, make prestress anchorage cable
Anchor pier does not protrude excavation face, does not influence structure arrangement.
The utility model is realized in this way:
A kind of embedded side slope prestress anchorage cable anchor pier structure, including being formed in slope excavating towards rock interior is embedded
Anchor pier slot is equipped with the anchor pier concrete of reinforced concrete structure in the anchor pier slot, is drilled in the anchor pier concrete reserved
Anchor cable hole, the reserved anchor cable hole extend into rock interior；Anchor rope component is equipped in reserved anchor cable hole；In the exposed of anchor rope component
End is equipped with anchor cable made of concreting and protects pier.
Further, the lateral surface slope excavating face of the anchor cable protection pier flushes.
Further, the anchor pier concrete and anchor cable protection pier are fully populated with the space in anchor pier slot.
Further, anchor cable protection pier blocks anchor pier concrete from outside completely.
Further, the space that the anchor pier concrete occupies in anchor pier slot is the 2/5-3/5 of anchor pier slot gross space,
Complementary space is that anchor cable protects pier.
The construction method of this embedded side slope prestress anchorage cable anchor pier structure of the utility model, includes the following steps:
Slope excavating face is formed after the completion of slope excavating, excavates out an anchor pier slot to rock interior on the basis of slope excavating face；It pours
Anchor pier concrete is built, and in internal reservation anchor cable hole, after anchor pier concrete strength is met the requirements, then carries out the peace of anchor rope component
Dress, interior anchoring, tensioning and locking finally implement anchor cable and protect pier, play the role of protecting anchor cable.
The anchor pier of prestress anchorage cable is set not protrude excavation face by the utility model, finally formed face and excavation face are neat
It is flat, easily facilitate the structure arrangement in later period.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is one embodiment schematic diagram of the utility model.
Description of symbols: 1- slope excavating face, 2- anchor pier slot, 3- anchor pier concrete, 4- reserve anchor cable hole, 5- anchor cable group
Part, 6- anchor cable protect pier.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but appoints not as to the utility model
What is limited.
The embedded side slope prestress anchorage cable anchor pier structure of the utility model is as shown in Figure 1, the structure is included in side slope opens
Digging face 1 is equipped with the anchor pier concrete of reinforced concrete structure to the embedded anchor pier slot 2 formed of rock interior in the anchor pier slot 2
3, reserved anchor cable hole 4 is drilled in the anchor pier concrete 3, which extends into rock interior；In reserved anchor cable hole
Anchor rope component 5 is equipped in 4；Anchor cable made of concreting, which is equipped with, in the exposed junction of anchor rope component 5 protects pier 6.Anchor rope component 5
Including anchor cable and its attachment.The lateral surface slope excavating face 1 of anchor cable protection pier 6 flushes.
For the one embodiment of the utility model in some hydropower station arch dam excavation as shown in Fig. 2, when implementing, slope excavating is complete
At rear formation slope excavating face 1, an anchor pier slot 2 is excavated out to rock interior on the basis of slope excavating face 1, anchor pier slot 2
Structure size need to meet the requirement of arrangement anchor rope component 5, and meet rock strength requirement, pour anchor pier concrete 3, generally steel
Reinforced concrete, and require in internal reservation anchor cable hole 4, after 3 intensity of anchor pier concrete is met the requirements, carrying out anchor rope component 5
Installation, interior anchoring, tensioning and locking, finally implement anchor cable and protect pier 6, play the role of protecting anchor cable.As can be seen that implementing
After, the anchor cable of prestress anchorage cable protects pier 6 not protrude slope excavating face 1, the lateral surface of finally formed anchor cable protection pier 6
It is flushed with slope excavating face 1, easily facilitates the structure arrangement in later period.
Certainly, the specific application example of above only the utility model, the utility model are all there are also other embodiments
The technical solution formed using equivalent substitution or equivalent transformation, is all fallen within protection scope required by the utility model.
