The utility model relates to retaining wall technical field, is specifically related to a kind of profiled-cross-section anchor note formula retaining wall.
Background technology
In roadbed reconstruction and extension project, keeping roadbed side slope stability is an important job, and newly-built retaining wall is one of common method.But there is following defect in newly-built retaining wall in roadbed reconstruction and extension project: old road excavated volume is large, old road stability is destroyed, need to interrupt existing traffic, do not make full use of old road stability, make new subgrade settlement large, construction investment is large, long in time limit, particularly under the landform of abrupt slope, mountain area, construction is difficult large, thereby the stability of side slope is worked the mischief.How to make full use of existing roadbed stability, solve the defect existing in roadbed reconstruction and extension project and become those skilled in the art's major issue urgently to be resolved hurrily.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiency that prior art exists, and a kind of easy construction is provided, can reduces construction investment, the construction period is short, instant effect,, the profiled-cross-section anchor note formula retaining wall that can improve the globality of the old and new roadbed and the stability of roadbed side slope little to ambient influnence.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of profiled-cross-section anchor note formula retaining wall, comprises bottom body of wall and the top body of wall that is connected in body of wall top, bottom, and the wall dorsal part of described top body of wall is provided with the side direction body of wall stretching out, and described bottom body of wall is connected with anchoring assembly.
As further improvement of the utility model:
The global sections of described top body of wall and side direction body of wall is L-shaped.
The wall of described bottom body of wall is carried on the back the direction of stretching out along side direction body of wall from bottom to top and is in tilted layout.
The cross section of described bottom body of wall is trapezoidal.
The anchor pole lockset that described anchoring assembly comprises anchor pole and coordinates with anchor pole, described bottom body of wall is provided with rockbolt installation hole, and described anchor pole is installed in described rockbolt installation hole.
Described retaining wall is steel concrete pour mass.
Described top body of wall is provided with drain hole.
Compared with prior art, the utility model has the advantage of:
Profiled-cross-section anchor note formula retaining wall of the present utility model, being mainly used in roadbed, to widen width less, the occasion that slope, roadside is steep, after construction, side direction body of wall extend between old road base and new Roadbed Soil, anchoring assembly with old road side slope (old retaining wall) anchor connection, bottom body of wall and old road side slope are locked together.In roadbed reconstruction and extension project; newly-increased banketing acts on top body of wall with the lateral earth pressure of embankment load formation; rely on side direction body of wall and banket between mutual frictional force and the uplift resistance that provides of anchoring assembly keep balance; thereby realize few excavation (not even excavation) Subgrade of old road; make full use of the stability of existing roadbed and old retaining wall, protect better the stability of roadbed side slope after reorganization and expansion.This retaining wall can make full use of old road side slope has completed the performance of consolidation settlement, good stability, reduce construction investment, under the condition of not interrupting existing traffic, construct, easy construction, duration is short, instant effect, little to ambient influnence, improve better the globality of the old and new's roadbed and the stability of roadbed side slope.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, profiled-cross-section anchor note formula retaining wall of the present utility model, being mainly used in roadbed, to widen width less, the occasion that slope, roadside is steep, comprise bottom body of wall 1 and the top body of wall 2 that is connected in bottom body of wall 1 top, the wall dorsal part of top body of wall 2 is provided with the side direction body of wall 3 stretching out, and wall dorsal part is the side that retaining wall combines with roadbed side slope, and bottom body of wall 1 is connected with anchoring assembly 4.In roadbed reconstruction and extension project, retaining wall is positioned at the old retaining wall of old road side slope 5() face sky side, the overall along continuous straight runs of side direction body of wall 3 is arranged, and extend between side slope 5 He Xin road roadbeds 7 in old road banket along the end face of old road side slope 5,4 of anchoring assemblies and 5 anchor connections of old road side slope, lock together bottom body of wall 1 and old road side slope 5.After construction; the lateral earth pressure that new road roadbed 7 and newly-increased filled load form acts on top body of wall 2; rely on side direction body of wall 3 and banket between mutual frictional force and the uplift resistance that provides of anchoring assembly 4 keep balance; thereby realize few excavation (not even excavation) Subgrade of old road 6; make full use of the stability of existing roadbed and old retaining wall, protect better the stability of roadbed side slope after reorganization and expansion.Profiled-cross-section anchor of the present utility model note formula retaining wall can make full use of old road side slope 5 has completed the performance of consolidation settlement, good stability, reduce construction investment, under the condition of not interrupting existing traffic, construct, easy construction, duration is short, instant effect, little to ambient influnence, improve better the globality of the old and new's roadbed and the stability of roadbed side slope.
In the present embodiment, the cross section of whole retaining wall is special-shaped, and wherein, the global sections of top body of wall 2 and side direction body of wall 3 is L-shaped.The wall of bottom body of wall 1 is carried on the back the direction of stretching out along side direction body of wall 3 from bottom to top and is in tilted layout, the cross section of whole bottom body of wall 1 is trapezoidal, as shown in Figure 1, the cross section of bottom body of wall 1 is inverted trapezoidal wide at the top and narrow at the bottom, can be better and old road side slope 5 combine closely, and ensure that whole retaining wall has good stressed property.
In the present embodiment, the anchor pole lockset 42 that anchoring assembly 4 comprises anchor pole 41 and coordinates with anchor pole 41, bottom body of wall 1 is provided with rockbolt installation hole 11, anchor pole 41 is installed in rockbolt installation hole 11, one end anchor connection of anchor pole 41 is in Subgrade of old road 6, the other end coordinates with anchor pole lockset 42 combines retaining wall and old road side slope 5, and anchored force is provided.Can reinforce old road side slope 5 by slurry injection technique if desired, improve the mechanical property of old road side slope 5, form old road grouting and reinforcing body, ensure that anchoring assembly 4 has reliable anchoring effect.In the time of anchoring construction, also tackle anchor pole 41 and apply prestressing force.
In the present embodiment, retaining wall is steel concrete pour mass, when construction, the face wall side and the end face cast that adopt concrete to be close to old road retaining wall form, configuration reinforcement 8 in retaining wall simultaneously, the concrete configuration of reinforcing bar 8 is referring to Fig. 3, and point and thicker lines in figure represent reinforcing bar 8.
