Description

Slope supporting structure and construction method thereof
Technical Field
The invention relates to the technical field of constructional engineering, in particular to a side slope supporting structure and a construction method thereof.
Background
The mountain land building is a very common construction project, and the technical problem of how to support a side slope is often encountered in the construction process, in particular to the side slope support caused by the excavation of a basement of the mountain land building. For mountain buildings in large cities, basements are mostly planned as developers pursue high investment and profits, and various buildings, roads and the like are arranged in the ground to the greatest extent. Thus, the space for supporting the side slope is extremely limited.
At present, the geotechnical engineering industry generally adopts anchor rods (cables), anchor rod (cable) retaining walls, rock anchor spraying, gravity retaining walls, reinforced concrete retaining walls, column plate retaining walls, slope ratio methods and other modes to support side slopes. However, the above slope supporting methods have the defects of large floor area and the like. Therefore, the conventional method would not be suitable for slope support during the construction of mountain buildings due to the limitation of the operation space.

A construction method of a slope supporting structure comprises the following steps:
a plurality of back row piles are driven into the mountain body along the ground red line;
performing earth excavation on the mountain body on one side of the rear row of piles back to the ground utilization red line, and excavating to a slope bottom elevation;
driving a plurality of front piles on one side of the rear piles, which faces away from the ground utilization line;
and pouring a cover plate at the position of the slope bottom elevation, and connecting the cover plate with the middle parts of the rear row piles and the tops of the front row piles.
In one embodiment, the method further comprises the following steps: and pouring a crown beam for connecting the plurality of rear row piles at the top of the rear row piles.

After the excavation is finished, a plurality of front piles which are completely buried into the ground bottom are driven into the bottom of the side slope, and the front piles and the rear piles are connected into a whole through pouring the cover plate. Therefore, the obtained side slope supporting structure can realize better support for the side slope. In addition, in the process of slope supporting, only two piling operations and one pouring of the cover plate are needed, and the formed cover plate can be used as outdoor land of mountain buildings. Therefore, the construction method of the slope supporting structure can realize slope supporting in a narrow space.
A slope supporting structure comprising:
the plurality of rear rows of piles bear against the side slope and are arranged at intervals along the extending direction of the ground red line, and each rear row of piles is partially buried in the ground bottom;

In one embodiment, the wale is integrally formed with the cover plate.
The front row piles, the rear row piles and the cover plate form an h-shaped supporting structure together, all the front row piles and part of the rear row piles are buried in the ground bottom and used as a base of the side slope supporting structure, and the rear row piles directly support the side slope. Moreover, the cover plate can be used as outdoor land for mountain buildings. Therefore, the above-ground part of the slope supporting structure occupies a very small space, so that a wide space can be provided for the plane arrangement of outdoor roads, basements and the like of mountain buildings.

The invention provides a side slope supporting structure and a construction method of the side slope supporting structure. The slope supporting structure can be obtained by utilizing the construction method of the slope supporting structure.
Referring to fig. 1, a slope supporting structure 100 according to a preferred embodiment of the present invention includes a rear row of piles 110, a front row of piles 120, and a cover plate 130.
The rear row of piles 110, the front row of piles 120 and the cover plate 130 are all of reinforced concrete structures and are generally formed by casting in situ. A plurality of back row piles 110 bear against the side slopes and are arranged at intervals along the extension direction of the ground redline. The ground red line refers to a boundary excavated for the mountain 200. In fig. 1, the reddish line is perpendicular to the plane of the drawing sheet, and is not shown. The ground red line can be a straight line or a curve. Therefore, the plurality of rear piles 110 may be spaced along a straight line or a curved line.
The rear row of piles 110 may be cylindrical, square, etc. A plurality of back row piles 110 bear against the side slopes. Therefore, the extending direction of the rear row piles 110 is determined by the shape of the side slopes. When the side slope is a slope, the plurality of back row piles 110 are arranged obliquely. And when the side slope extends vertically, the plurality of rear row piles 110 are arranged perpendicular to the ground. The rear row of piles 110 directly contact the side slope, thereby reinforcing the side slope. To better reinforce the side slope, the top of the rear row of piles 110 is generally flush with or slightly above the top of the side slope.
Also, each rear row of piles 110 is partially buried in the ground. Specifically, the length of the rear row of piles 110 is greater than the height of the side slope, so that the bottom of the rear row of piles 110 can be buried in the ground. Thus, the part buried in the ground can be used as a base to provide stable supporting force.
In this embodiment, the slope supporting structure 100 further includes a crown beam 140 positioned on top of the rear row of piles 110 and connecting the plurality of rear rows of piles 110.
The crown beam 140 is also typically a cast-in-place reinforced concrete structure. Moreover, the crown beam 140 generally extends in the extension direction of the ground line so as to be able to connect a plurality of spaced-apart rear row piles 110 in sequence. The crown beam 140 may be cast and formed together with the rear row of piles 110, or the crown beam 140 may be obtained by re-formwork and casting and tamping after a plurality of rear row of piles 110 are formed. The crown beam 140 can connect a plurality of back row piles 110 into a whole, so that the stability of the back row piles 110 is stronger, and the reinforcing effect for the side slope is better.
The front row of piles 120 may be the same shape as the rear row of piles 110. Wherein the front row of piles 120 is generally smaller in length than the rear row of piles 110. The plurality of front piles 120 are spaced apart from the plurality of rear piles 110. Specifically, the front row of piles 120 is located on a side of the rear row of piles 110 facing away from the reddish ground line, i.e., the plurality of front rows of piles 120 are located on an inner side of the reddish ground line. The plurality of front piles 120 are arranged in the same manner as the rear piles 110, that is, at intervals in the extending direction of the ground line. The number of front row piles 120 may be the same as the number of rear row piles 110, and arranged in one-to-one correspondence with the plurality of rear row piles 110.
It should be noted that the pile diameters, the pile distances and the lengths of the rear row piles 110 and the front row piles 120 can be determined by corresponding models according to the stability requirement.
Further, each front row of piles 120 is buried in the ground and the top extends to the elevation of the slope bottom. The elevation of the slope bottom refers to the plane of the bottom of the side slope. That is, a plurality of front piles 120 are all completely buried in the ground.
The cover plate 130 connects the top of the plurality of front piles 120 and the middle of the plurality of rear piles 110. Thus, the slope supporting structure 100 is entirely h-shaped. The entire front row of piles 120 and a portion of the rear row of piles 110 are buried in the ground and the whole serves as a base of the slope supporting structure 100. The front row of piles 120 and the rear row of piles 110 cooperate to form a support form of a double row pile structure, thereby being capable of providing stable support to the entire slope supporting structure 100.
In addition, since the cover plate 130 is substantially flush with the bottom of the side slope, the area of the surface of the cover plate 130 may also serve as an outdoor land for mountain construction, such as a residential road or a greening land. Moreover, the front row of piles 120 is completely buried in the ground, so that the part of the slope supporting structure 100 extending out of the ground is only a part of the rear row of piles 110, and the occupied space is very small. Therefore, the slope supporting structure 100 can support a slope in a narrow space, and thus can provide a wide space for a planar arrangement such as an outdoor road of a mountain building and a basement.
In this embodiment, the slope supporting structure 100 further includes a wale 150 located at the middle of the rear row piles 110 and connecting the plurality of rear row piles 110, and the cover plate 130 is connected to the middle of the plurality of rear row piles 110 through the wale 150.
The wale 150 is also typically a cast-in-place reinforced concrete structure, which may be the same structure as the crown beam 140. The wale 150 may be cast and formed together with the rear row of piles 110, or the wale 150 may be obtained by formwork re-erection and casting after a plurality of rear row of piles 110 are formed. The wale 150 can further enhance the stability of the plurality of piles 110 in the rear row, so that the reinforcement effect for the side slope is also better.
It should be noted that, in other embodiments, instead of the crown beam 140 and the wale 150, a plurality of tie beams may be cast, and the tie beams intersect with the plurality of rear piles 110 to form a grid-like structure, which may also play a role in enhancing the stability of the plurality of rear piles 110.
Further, in the present embodiment, the wale 150 is integrally formed with the cover plate 130. Specifically, after the front row of piles 120 is formed, the cover plate 130 and the wale 150 are cast while erecting the formwork. Thus, the cover plate 130 and the back row piles 110 can be connected more firmly, and the stability of the slope supporting structure 100 is higher.
The side slope supporting structure 100, the front row piles 120, the rear row piles 110, and the cover plate 130 together form an h-shaped supporting structure, all of the front row piles 120 and part of the rear row piles 110 are buried in the ground to serve as a base of the side slope supporting structure 100, and the rear row piles 110 directly support the side slope. Also, the cover plate 130 may double as an outdoor land for mountain construction. It can be seen that the above-described slope supporting structure 100 occupies a very small space in the above-ground portion, and thus can provide a wide space for a planar arrangement such as an outdoor road and a basement of a mountain building.
Referring to fig. 2, the construction method of the slope supporting structure in the preferred embodiment of the present invention includes steps S301 to S304:
step S301, driving a plurality of piles 110 in the mountain 200 along the red line of the ground.
Specifically, the rear row of piles 110 may have a cylindrical shape, a square shape, or the like. The rear row of piles 110 are typically cast in place. The mountain 200 can be drilled downwards, and the aperture and depth of the drilled hole can be determined according to the required pile diameter and length of the rear row of piles 110; then, putting a steel bar framework into the drilled hole; and finally, pouring and smashing concrete and solidifying the concrete. Therefore, in the process of forming the back row of piles 110, the hole wall of the drilled hole can be used as a template for concrete pouring. Therefore, in the forming process, additional die filling and die removing operations are not needed, so that the engineering construction efficiency can be improved, and the cost can be saved.
A plurality of the rear row piles 110 are arranged at intervals in the extending direction of the ground line. As previously mentioned, the red-to-earth line refers to a boundary excavated for the mountain 200. The ground red line can be a straight line or a curve. Therefore, the plurality of rear piles 110 may be spaced along a straight line or a curved line.
As shown in fig. 3, at this time, the plurality of rear piles 110 formed are all completely embedded in the mountain 200.
In this embodiment, the method for constructing a slope supporting structure further includes the steps of: and pouring a crown beam 140 connecting a plurality of rear row piles 110 on the top of the rear row piles 110.
In particular, the crown beam 140 is also typically a cast-in-place reinforced concrete structure. The crown beam 140 generally extends in the extension direction of the right-red line so that a plurality of spaced rear row piles 110 can be connected in sequence. The crown beam 140 may be cast and formed together with the rear row of piles 110, or the crown beam 140 may be obtained by formwork re-erection and casting after a plurality of rear row of piles 110 are formed. The crown beam 140 can connect a plurality of the rear row piles 110 as a whole, thereby making the rear row piles 110 more stable.
Step S302, performing earth excavation on the mountain 200 at the side of the plurality of back row piles 110 opposite to the ground utilization red line, and performing excavation to the slope bottom elevation.
Specifically, after earth excavation is performed on the mountain 200 to the slope bottom elevation, a side slope can be formed. The elevation of the slope bottom refers to the plane of the bottom of the side slope. As shown in fig. 4, after the mountain 200 is excavated to the slope bottom elevation, the portions of the plurality of rear piles 110 higher than the slope bottom elevation are exposed.
At this time, the plurality of rear piles 110 bear against the slope. Therefore, the extending direction of the rear row piles 110 is determined by the shape of the side slopes. When the side slope is a slope, the plurality of back row piles 110 are arranged obliquely. And when the side slope extends vertically, the plurality of rear row piles 110 are arranged perpendicular to the ground.
Since the mountain body 200 is not excavated in advance, the side slope is formed by excavation after the rear row of piles 110 are formed. The rear row of piles 110 directly contact with the side slope and can reinforce the side slope. Therefore, when the mountain 200 is excavated to form a slope, the rear row piles 110 may play a role of reinforcing the slope to some extent, thereby preventing the mountain 200 from collapsing during the excavation of the earth.
In step S303, a plurality of front piles 120 are driven into the rear piles 110 on the side facing away from the ground line.
Specifically, the side of the rear row of piles 110 facing away from the ground red line is the area where the earth excavation is performed. The front row of piles 120 may have the same structure and shape as the rear row of piles 110, and may have a cylindrical shape, a square shape, or the like. Similarly, a hole can be drilled downwards at the bottom of the side slope, and the aperture and the depth of the drilled hole can be determined according to the pile diameter and the length of the front row of piles 120; then, putting a steel bar framework into the drilled hole; finally, the concrete is poured and tamped and solidified to obtain the front row of piles 120. Therefore, in the process of forming the front row of piles 120, the hole wall of the drilled hole can be used as a template for concrete pouring. Therefore, the forming process of the front row of piles 120 also does not need to perform the operations of mold loading and mold unloading, thereby improving the efficiency and saving the cost.
Referring again to fig. 4, each of the front row of piles 120 is completely buried in the ground, and only the top thereof extends to the elevation of the slope bottom. The plurality of front piles 120 are arranged in the same manner as the rear piles 110, that is, at intervals in the extending direction of the ground line. The plurality of front piles 120 are arranged in the same manner as the rear piles 110, that is, at intervals in the extending direction of the ground line. The number of front row piles 120 may be the same as the number of rear row piles 110, and arranged in one-to-one correspondence with the plurality of rear row piles 110.
It should be noted that the pile diameters, the pile distances and the lengths of the rear row piles 110 and the front row piles 120 can be determined by corresponding models according to the stability requirement.
Step S304, casting a cover plate 130 at the elevation position of the slope bottom, and connecting the cover plate 130 with the middle parts of the plurality of rear piles 110 and the top parts of the plurality of front piles 120.
Referring to fig. 5, the cover plate 130 can be obtained by erecting a mold at the elevation of the slope bottom and casting and tamping. The cover plate 130 also generally extends along the extension of the ground redline. The cover plate 130 connects the plurality of front piles 120 with the plurality of rear piles 110 in an integral h-shape. The entire front row of piles 120 and a portion of the rear row of piles 110 are buried in the ground and the whole serves as a base of the slope supporting structure 100. The front row of piles 120 and the rear row of piles 110 cooperate to form a support form of a double row pile structure, thereby being capable of providing stable support to the entire slope supporting structure 100.
Further, since the cover 130 is substantially flush with the bottom of the slope, the area of the surface of the cover 130 can also serve as an outdoor land for mountain construction. Moreover, the front row of piles 120 is completely buried in the ground, so that the part of the slope supporting structure 100 extending out of the ground is only a part of the rear row of piles 110, and the occupied space is very small. Therefore, the construction method of the slope supporting structure can realize slope supporting in a narrow space and can provide a wide space for plane arrangement of mountain building outdoor roads, basements and the like.
In this embodiment, the method for constructing a slope supporting structure further includes the steps of: and pouring a wale 150 connecting the middle parts of the plurality of rear row piles 110 at the elevation position of the slope bottom.
The wale 150 is also typically a cast-in-place reinforced concrete structure, which may be the same structure as the crown beam 140. The wale 150 may be cast and formed together with the rear row of piles 110, or the wale 150 may be obtained by formwork re-erection and casting after a plurality of rear row of piles 110 are formed. The wale 150 can further enhance the stability of the plurality of piles 110 in the rear row, so that the reinforcement effect for the side slope is also better.
Further, in the present embodiment, the wale 150 is integrally formed with the cover plate 130.
Specifically, after the front row of piles 120 is formed, a formwork can be erected at the bottom of the side slope, and the cover plate 130 and the wale 150 can be poured at the same time. Thus, the cover plate 130 and the back row piles 110 can be connected more firmly, and the stability of the finally obtained slope supporting structure 100 is higher.
Referring to fig. 6 and 7, in the present embodiment, the method for constructing a slope supporting structure further includes the steps of: excavating earth on one side of the front row of piles 120, which faces away from the rear row of piles 110, and excavating to the elevation of the basement base; and pouring the basement 400, and backfilling the gap between the basement 400 and the front row of piles 120 after pouring to the elevation of the first floor.
Specifically, the purpose of performing earth excavation on the side of the front row of piles 120 opposite to the rear row of piles 110 is to form a foundation pit for placing the basement 400. The elevation of the basement base refers to the height of the lowest floor of the basement 400, and the elevation of the first floor board refers to the height of the uppermost floor of the basement 400. Furthermore, the basement floor elevation should be higher than the bottom of the front row of piles 120, so as to avoid over-excavation and the stability of the front row of piles 120 being damaged.
Then, the basement 400 is formed layer by erecting and pouring in the foundation pit. As can be seen, the front piles 120 can be used not only as a base of the slope supporting structure 100, but also as a foundation pit support in the excavation stage of the basement 400. Therefore, a supporting structure does not need to be additionally arranged for the foundation pit of the basement 400, and the efficiency of engineering construction is improved and the cost is reduced. After backfilling, the front row of piles 120 are completely buried into the ground again, so that a good side supporting effect can be still achieved.
Further, in this embodiment, the elevation of the first floor is flush with the surface of the cover plate 130. Therefore, when the basement 400 is poured, the surface of the top slab thereof is connected with the surface of the cover plate 130 to form a whole plane. Therefore, a flat area with a large area can be obtained at the bottom of the side slope, and layout of other outdoor buildings is facilitated.
In the construction method of the slope supporting structure, before the mountain 200 is excavated, the plurality of back row piles 110 are driven along the red line, and when the slope is formed by excavation, the back row piles 110 can play a role of reinforcing the slope to a certain extent. After the excavation is finished, a plurality of front piles 120 completely buried in the ground are driven into the bottom of the side slope, and the front piles 120 and the rear piles 110 are connected into a whole by pouring the cover plate 130. Thus, the resulting slope support structure 100 is able to achieve better support of the slope. In addition, in the process of slope supporting, only two piling operations and one pouring of the cover plate 130 are needed, and the formed cover plate 130 can be used as the outdoor land of the mountain building. Therefore, the construction method of the slope supporting structure can realize slope supporting in a narrow space.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
