Description
Technical Field
The utility model relates to a buttress type retaining wall suitable for a high-fill wall top in a mountain area and having a large load, and belongs to the technical field of slope supporting engineering.
Background
The counterfort retaining wall is used as one of supporting structures, has the advantages of simple structure, convenient construction and better performance of material strength, and can be widely applied to filling projects with lower foundation bearing capacity and deficient stone materials in engineering.
In the areas of the middle and the west of China, mountainous land terrains are abundant, flat land resources are rare, temporary sites required for construction of civil engineering in the areas are generally high-fill filling sites, and if large-scale construction equipment such as gantry cranes are arranged in the temporary sites, the buttress retaining wall serving as a site support has the problems that construction is inconvenient, the buttress is easy to crack or even damage due to excessive tensile stress on the top under the condition of bearing large load, the upper end and the lower end of the retaining wall are easy to displace greatly and the like.
SUMMERY OF THE UTILITY MODEL
In order to overcome the problems in the background art, the utility model can still provide good bearing capacity and good stability when a large load is acted on the wall top, has good mechanical property, can improve the stress distribution of the counterfort plate, avoids the damage of the counterfort plate caused by stress concentration, ensures the stability of the side slope and the safety of field construction, and can be popularized and applied.
In order to overcome the problems in the background art and solve the problems, the utility model is realized by the following technical scheme:
the buttress formula barricade suitable for mountain area high fill wall crown effect has heavy load includes shingle nail board, toe board, wall heel board, buttress, secondary wall heel board, stiffening rib, be connected with wall toe board and wall heel board on the shingle nail perpendicularly, is connected with the buttress between shingle nail board and the wall heel board, and buttress perpendicular to shingle nail board and wall heel board, shingle nail and wall heel board contained angle position are provided with secondary wall heel board, and secondary wall heel board perpendicular to buttress, and secondary wall heel board and shingle nail contained angle position are provided with stiffening rib, and wall toe board and shingle nail contained angle position are provided with stiffening rib.
The utility model has the beneficial effects that:
the utility model solves the problems of displacement of the counterfort and structural damage caused by stress concentration easily caused by the counterfort under the action of large load by improving the counterfort and arranging the secondary wall heel plate and the stiffening rib, can stably and safely support the mountain high fill engineering, can still provide good bearing capacity and have good stability when the counterfort acts with larger load, has good mechanical property, can improve the stress distribution of the counterfort, avoids the damage caused by the stress concentration of the counterfort, ensures the stability of the side slope and the safety of field construction, and can be popularized and applied.

FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a side view of the present invention.
The reference numbers in the figures are: 1-wall panel, 2-wall toe board, 3-wall heel board, 4-buttress, 5-secondary wall heel board and 6-stiffening rib.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1-2, the buttress 4 type retaining wall applicable to the high-fill wall top in mountainous areas and having high load comprises a wall panel 1, a toe panel 2, a heel panel 3, a buttress 4, a secondary heel panel 5 and stiffening ribs 6, wherein the wall panel 1 is vertically connected with the toe panel 2 and the heel panel 3, the buttress 4 is connected between the wall panel 1 and the heel panel 3, the buttress 4 is perpendicular to the wall panel 1 and the heel panel 3, the secondary heel panel 5 is arranged at the included angle position of the wall panel 1 and the heel panel 3, the secondary heel panel 5 is perpendicular to the buttress 4, the stiffening ribs 6 are arranged at the included angle position of the secondary heel panel 5 and the wall panel 1, and the stiffening ribs 6 are arranged at the included angle position of the toe panel 2 and the wall panel 1.
In this embodiment, the toe board 2 and the heel board 3 are at the same horizontal position, the heel board 33 is provided with a secondary heel board 55, the wall panel 11, the heel board 33 and the buttress 4 board 4 are connected by reinforcing steel bars, the stability of the buttress 4 board 4 is ensured, the width of the secondary heel board 5 is set within the range of 0.5m to 1.2m, the top of the buttress 4 board 4 is widened by 0.5m and is flush with the top of the wall panel 11, and the raised bottom angle is increased by 1.0m and is flush with the end of the heel board 3, by this way, the local damage of the buttress 4 board 4 caused by stress concentration can be avoided, the back of the wall panel 11 is filled with back pressure filling soil, and this measure can reduce the displacement generated at the upper and lower ends of the retaining wall, so that the retaining wall is safer, and the height of the buttress 4 retaining wall is greater than 10 m.
The utility model solves the problems of displacement of the counterfort and structural damage caused by stress concentration easily caused by the counterfort under the action of large load by improving the counterfort and arranging the secondary wall heel plate and the stiffening rib, can stably and safely support the mountain high fill engineering, can still provide good bearing capacity and have good stability when the counterfort acts with larger load, has good mechanical property, can improve the stress distribution of the counterfort, avoids the damage caused by the stress concentration of the counterfort, ensures the stability of the side slope and the safety of field construction, and can be popularized and applied.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
