Description

Construction platform for manually excavated bored piles on steep slopes Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a construction platform for manually excavated bored piles on steep slopes. Background Technology

[0002] In the construction of buildings or highways near mountains, steep slope support is often involved. In the construction of high and steep slopes with poor construction conditions, pile driving is particularly difficult due to limitations in construction conditions and pile driving equipment. Because rotary drilling rigs are heavy, large earthen platforms are needed to meet the working face of the piling equipment. However, this method involves a huge amount of earthwork and may damage surrounding woodlands or equipment. Therefore, manual excavation of bored piles is often used. However, due to soil conditions, in some terrains with high and steep slopes, it is impossible to build a construction platform by piling earth, as it is prone to collapse, leading to problems such as inconvenience for construction workers and difficulty in transporting waste.

[0003] Therefore, the inability to form a construction platform by stacking earthworks is a pressing technical problem in the field for manually excavated bored piles on steep slopes due to the terrain and geological conditions of the steep slopes. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a construction platform for manually excavated bored piles on steep slopes. In the construction of steep slopes, it can adapt to the construction environment of sandy landforms, thereby facilitating the construction of manually excavated bored piles by construction personnel. Moreover, the height of the construction platform is adjustable, which can be used to adapt to different construction progress and construction needs.

[0005] This utility model discloses a construction platform for manually excavated bored piles on steep slopes, comprising:

[0006] The platform body has a construction opening located above the borehole of the pile to be excavated.

[0007] A support system, located below the platform body to provide support for the platform body, includes at least two rows of columns arranged sequentially from high to low along a steep slope. The columns are drivable and extendable, allowing the height of the platform body to be adjusted.

[0008] Furthermore, the support system also includes a lifting device for driving the column to extend and retract. The lifting device can be located at the bottom of the column or between two adjacent segments of the column, and is used to change the distance between two adjacent segments to achieve extension and retraction.

[0009] Furthermore, the column comprises at least two segments, and the lifting device comprises clamp I, clamp II, and a lifting member. Clamp I clamps one segment, clamp II clamps the other segment, and clamps both ends of the lifting member respectively.

[0010] Furthermore, the lifting component is a hydraulic jack or a hydraulic strut.

[0011] Furthermore, the main body of the platform includes a steel structure frame, the construction opening is opened on the steel structure frame, the columns include front columns and rear columns, one end of the bottom of the steel structure frame is fixed to the steep slope, the other end of the bottom of the steel structure frame is fixed to the front column, and the rear column is set at the bottom of the steel structure frame and is set behind the front column.

[0012] A steel mesh is provided on the steel structure frame, and the steel mesh has a clearance opening corresponding to the construction opening.

[0013] Furthermore, the construction platform also includes hoisting equipment, which is mounted on the steel structure frame and includes a suspended basket that can be driven to move.

[0014] Furthermore, the construction platform also includes a ventilation device, which includes a blower and a flexible air supply hose connected to the outlet of the blower. The blower is mounted on a steel structure frame, and the flexible air supply hose extends into the borehole of the pile to be excavated through the construction port.

[0015] Furthermore, the construction platform also includes a rope ladder, one end of which is located at the construction opening, and the other end of which extends downward from the construction opening into the borehole of the pile to be excavated.

[0016] Furthermore, the platform body also includes detachable guardrails, which are respectively installed at the edges of the steel structure frame and the edges of the construction opening.

[0017] Furthermore, the support system also includes support components, which are respectively disposed between two adjacent columns of the front row and between two adjacent columns of the rear row. The support components include scissor braces and horizontal struts.

[0018] The beneficial effects of this utility model are as follows: The construction platform for manually excavated bored piles on steep slopes of this utility model consists of two rows of columns arranged at the front and rear positions near the borehole of the pile to be excavated to form a support system. The main body of the platform is set on the support system. At the same time, the main body of the platform is provided with a construction opening, which facilitates the construction personnel to transport construction materials and waste generated during the construction process into the borehole of the pile to be excavated through the construction opening.

[0026] Figure 1 is a structural schematic diagram of the construction platform of this utility model when installed on a steep slope; Figure 2 is a structural schematic diagram of the construction platform of this utility model; Figure 3 is a structural schematic diagram of the column and lifting device; Figure 4 is a structural schematic diagram of the hoisting equipment; Figure 5 is a structural schematic diagram of the air supply equipment. As shown in Figures 1-5: the construction platform for manually excavated bored piles on steep slopes in this embodiment includes:

[0027] The platform body is equipped with a construction opening, which is located above the borehole of the pile to be excavated. The platform body is generally a steel structure frame 4. When the construction platform is erected on a high and steep slope, the construction opening is located above the borehole 8 of the pile to be excavated (the location to be manually excavated to form the pile foundation). This facilitates the transportation of materials into the borehole 8 through the construction opening or the removal of waste generated in the borehole 8 during the construction process, making it convenient for construction personnel to operate.

[0028] A support system, located beneath the platform body, provides support for the platform and includes at least two rows of columns 2 arranged sequentially from high to low along a steep slope 1. These columns 2 are drivable and extendable, allowing for height adjustment of the platform body. In this structure, concrete is poured where the columns 2 are placed on the steep slope 1. The columns 2 are fixedly connected to the platform body by welding or flange bolts. Each row of columns 2 comprises several spaced columns 2, and their positions are rationally arranged according to the terrain of the steep slope 1 to improve the stability of the platform body and adapt to the elevation differences of steep slopes. The columns 2 can be sleeve-type structures, drivable and extendable, facilitating height adjustment of the platform body to meet different construction needs. Furthermore, the extendable nature of the columns 2, compared to the one-piece molding of existing technologies, saves construction costs and facilitates transportation. The height of the columns 2 can be adjusted according to on-site construction conditions. The extension and retraction of the columns 2 can be achieved by connecting two segments with an extension joint or by using clamps and hydraulic struts.

[0029] In this embodiment, the support system further includes a lifting device for driving the extension and retraction of the column. The lifting device can be located at the bottom of the column 2 or between two adjacent segments of the column 2, used to change the distance between two adjacent segments, thereby achieving extension and retraction. In this structure, the column is a segmented structure comprising several segments. The lifting device can be a structure of hydraulic struts / jacks and clamps. By clamping two clamps onto two segments respectively, and placing the hydraulic struts or jacks between the two clamps, the axial distance between the two clamps can be adjusted, thereby driving the extension and retraction of the two segments; or the lifting device can be placed at the bottom of the column 2, which can also achieve the adjustment of the column height within a certain range.

[0030] In this embodiment, the column 2 includes at least two segments, and the lifting device includes clamp I 16, clamp II 17 and lifting member 15. Clamp I 16 clamps one segment, clamp II 17 clamps the other segment, and clamps the two ends of the lifting member 15 respectively.

[0031] The clamps I16 and II17 are respectively clamped to two adjacent segments. The lifting member 15 is set between clamps I16 and II17 to adjust the axial spacing between clamps I16 and II17, so as to change the telescopic length of the column 2. In this structure, the clamp generally includes two ring-shaped parts, which are fastened together by bolts. This is an application of existing technology and will not be described in detail here. When the number of segments of each column 2 is n (n is a positive integer greater than zero), the number of lifting devices is n-1. Clamp I 16 clamps one segment, and clamp II 17 clamps another adjacent segment. At the same time, clamp I 16 and clamp II 17 are provided with mounting plates 18 for installing the lifting component 15. The mounting plate 18 can be a ring structure with a diameter larger than that of clamp I 16 and clamp II 17. The mounting plate 18 is fixedly connected to clamp I 16 and clamp II 17 respectively. The mounting plate 18 can be a split ring structure, which is welded to the ring-shaped parts of the corresponding clamps, and finally forms a ring structure to form an installation platform for installing the lifting component 15.

[0032] In this embodiment, the lifting component 15 is a hydraulic jack or a hydraulic strut. The number of hydraulic jacks or hydraulic struts can be several, and can be set according to usage needs. The structure of the hydraulic jacks and hydraulic struts is an application of existing technology and will not be described in detail here.

[0033] In this embodiment, the platform body includes a steel structure frame, the construction opening is opened on the steel structure frame, the columns 2 include front row columns 2 and rear row columns 2, one end of the bottom of the steel structure frame 4 is fixed to the steep slope 1, the other end of the bottom of the steel structure frame 4 is fixed to the front row columns 2, and the rear row columns 2 are set at the bottom of the steel structure frame 4 and are set behind the front row columns 2; the bottom is the lower part relative to the vertical direction in Figure 1, the steel structure frame 4 is a frame structure composed of several horizontal beams and vertical beams, and the horizontal beams and vertical beams can be connected by welding or bolts, and the construction opening is a passage opened on the steel structure frame 4.

[0034] As shown in Figure 1, relative to the left and right direction of Figure 1, the left end of the bottom of the steel structure frame 4 is set on the steep slope 1. Concrete is poured at the contact point between the steel structure frame 4 and the steep slope 1 to form an installation foundation. The installation foundation is provided with installation holes. The steel structure frame 4 is fixed to the installation foundation with bolts and nuts. The right end of the steel structure frame 4 is fixedly installed on the front row of columns 2. In this structure, the front and back are only used to distinguish the two rows of columns 2. The rear direction is closer to the slope surface of the steep slope 1, and the front direction is away from the slope surface of the steep slope 1. The rear row of columns 2 is set between the slope surface of the steep slope 1 and the front row of columns 2 and forms support for the middle of the steel structure frame 4. Both the front row of columns 2 and the rear row of columns 2 contain several columns 2, including at least two. The height of the front row of columns 2 is generally higher than that of the rear row of columns 2 (that is, the front row of columns 2 can be a three-section structure, and the rear row of columns 2 can be a two-section structure).

[0035] A steel mesh is installed on the steel frame 4, and the steel mesh has a clearance opening corresponding to the construction opening. The steel frame 4 is a two-layer frame structure to improve its load-bearing capacity. The steel mesh on the steel frame 4 facilitates the placement of construction tools and the passage of construction personnel.

[0036] In this embodiment, the construction platform further includes hoisting equipment, which is mounted on the steel structure frame 4. The hoisting equipment includes a suspended basket 7, which can be driven to move. The suspended basket 7 can be hoisted by a hoisting machine, or by the cooperation of a triangular bracket, pulleys 13, and a winch 14. In use, the triangular bracket includes two triangular supports 11 and a crossbar 12 located between the two triangular supports 11 and at the top. The two triangular supports 11 are located on both sides of the construction opening and installed on the steel structure frame 4. Multiple pulleys 13 are hung on the crossbar 12. One end of the steel rope of the winch 14 is connected to the suspended basket 7 through the pulleys 13 (the suspended basket is suspended on the steel rope). The hoist 7 can be moved vertically relative to the height shown in Figure 1 by operating the winch 14. The cooperative structure of the winch 14, triangular bracket, and pulleys 13 is an application of existing technology and will not be described in detail here. This facilitates the conveying of materials into and out of the orifice 8.

[0037] In this embodiment, the construction platform further includes an air supply device, which includes a blower 9 and a flexible air supply hose 10 connected to the air outlet of the blower 9. The blower 9 is mounted on the steel frame 4, and the flexible air supply hose 10 extends into the borehole 8 of the pile to be excavated through the construction port. The blower 9 generally includes a fan or impeller. The structure of the blower 9 is an application of existing technology and will not be described in detail here. The blower 9 is mounted on the steel frame 4 and can be fixedly connected to the steel frame by bolts. The flexible air supply hose 10 extends into the borehole 8 through the construction port to facilitate the supply of air into the borehole 8 and avoid safety issues.

[0038] In this embodiment, the construction platform further includes a rope ladder 6. One end of the rope ladder 6 is located at the construction opening, and the other end extends downward from the construction opening into the borehole 8 of the pile to be excavated. The rope ladder 6 generally consists of support rods and ropes, which is an application of existing technology and will not be described in detail here. One end of the rope ladder 6 is fixed at the construction opening, and the other end extends downward through the construction opening (relative to the vertical direction in Figure 1) into the borehole 8, facilitating the entry and exit of construction personnel from the borehole 8.

[0039] In this embodiment, the platform body also includes detachable guardrails 5, which are respectively set on the edge of the steel structure frame 4 and the edge of the construction opening. The guardrails 5 are detachably connected to the steel structure frame 4. This can be achieved by setting mounting holes on the steel structure frame, setting connecting plates on the guardrails 5, and then detachably fixing them to the steel structure frame 4 and the construction opening with bolts (bolts are inserted into the mounting holes for fastening). When the guardrails 5 are set on the steel structure frame 4, the end of the steel structure frame 4 that is set on the steep slope 1 does not have the guardrails 5 installed, which facilitates the entry and exit of construction personnel and construction equipment. At the same time, an entrance and exit are also set near the edge of the steep slope 1 at the construction opening. That is, the guardrails 5 do not completely surround the construction opening, which facilitates the entry and exit of construction personnel and ensures construction safety.

[0040] In this embodiment, the support system further includes support components 3, which are respectively disposed between two adjacent columns 2 of the front row and between two adjacent columns 2 of the rear row. Each support component 3 includes scissor braces and horizontal struts. Multiple sets of support components 3 are provided, with the number of sets matching the number of rows of columns 2. Each scissor brace includes two diagonal braces, and the horizontal struts are positioned horizontally below the scissor braces and connected to the two diagonal braces. By providing support components 3, the structural stability and load-bearing capacity of the support system are improved.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
