Description

Technical Field

[0001] The present embodiment relates to the field of bridge engineering of civil engineering, and specifically to a casing guide frame fixed by anchor piles. Background Art

[0002] With the rapid economic development, higher requirements are placed on traffic and transportation. Large-span cable-stayed bridges and suspension bridges have emerged. The foundation of super-large bridges needs to bear the weight of the superstructure, vehicle loads, wind loads and other loads. The bridge foundation is subject to huge horizontal and vertical forces. In addition, the ground geological conditions of large-span bridges are complex and the foundation bearing capacity is required to be high. Extra-long diameter pile foundations are frequently used as the main bearing structure in cable-stayed bridges and suspension bridges.

[0003] Steel pipe composite pile is a composite pile foundation that uses steel casing to wrap the core concrete to bear the force together. It has high bearing capacity and good reliability. As a component of the pile foundation, the center position and verticality of the permanent steel casing determine the quality of the pile foundation. Therefore, the steel casing must be accurately positioned when it is driven.

[0004] In the existing steel casing construction, the land-based steel casing guide frame cannot be welded and fixed to the steel platforms on both sides like the water pile foundation steel casing guide frame to ensure stability and reliability. The land-based steel casing can only rely on the support and positioning of the guide frame, and large-diameter and extra-long steel casings require the selection of vibrating hammers with sufficient excitation force. If the excitation force is too large during the installation process, the guide frame will shake and vibrate greatly, causing the center position of the steel casing to shift and the verticality to be difficult to control. It is difficult to correct the deviation after the deviation, which indirectly increases the construction cost and the risk during the construction process. Utility Model Content

[0005] The embodiment of this specification provides a casing guide frame fixed by anchor piles, including a frame body, characterized in that:

[0006] The frame body includes a plurality of columns and a plurality of frames erected on the columns, wherein the columns and the frames enclose a columnar space for clamping the casing; and the frame is provided with a plurality of limiting holes for the anchor piles to pass through.

[0007] The embodiments of the present specification anchor the land guide frame, and anchor piles are driven into the apex of the casing guide frame. The anchor piles penetrate deep into the ground to firmly fix the guide frame at a preset point to avoid displacement. The anchor piles are vertically arranged at the apex of the guide frame, which ensures that the guide frame maintains good verticality during construction, solving the problem that the land steel casing guide frame in the prior art is easily offset and skewed.

[0008] As a further preferred solution, the limiting hole is provided at the vertex of the frame and vertically penetrates the frame.

[0009] As a further preferred solution, the frame is welded and fixed to each of the columns; the shape of the frame corresponds to the shape surrounded by the multiple columns.

[0010] As a further preferred solution, the frame further includes a plurality of limit rods, and the limit rods connect two adjacent sides of the frame.

[0011] As a further preferred solution, the distance between the intersection of the limiting rod and each side of the frame and the vertex of the frame does not exceed 1 / 3 of the side length of the frame.

[0012] As a further preferred solution, the frame further includes an adjustment portion disposed at the midpoint of each side and facing the protective tube, and the adjustment portion is used to adjust the verticality of the protective tube.

[0013] As a further preferred solution, there are at least two frames distributed at at least two different heights.

[0014] As a further preferred solution, there are at least three upright posts, which are vertically arranged at the vertices of the frame.

[0015] As a further preferred solution, a plurality of reinforcing rods are provided between the frames of different heights, and the reinforcing rods form a scissors brace structure.

[0016] As a further preferred solution, a walking ladder is provided on one side of the frame body, and a guardrail is provided above the walking ladder.

[0017] The main beneficial effects of the above technical solution are:

[0018] Anchor piles are driven into the soil to provide anchoring force for the casing guide frame, ensuring that the guide frame does not move during the construction of large-diameter pile foundations, thereby improving the verticality of the steel casing, that is, the casing has high accuracy in the vertical direction without obvious tilt or deviation. This avoids deviation correction after construction, reduces additional expenses, improves work efficiency, and the guide frame can be recycled and reused, reducing costs.

[0019] Further or more detailed beneficial effects will be described in detail in conjunction with specific examples in the specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] As shown in the figure: a frame body 1, a column 2, a frame 3, a limit rod 31, a limit hole 4, an adjustment part 5, a reinforcement rod 6, a walking ladder 7, and a guardrail 8. DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the specific implementation of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the implementation of the utility model.

[0025] A casing guide frame fixed by anchor piles, such as Figure 1 and Figure 2 As shown, the frame body 1 includes a plurality of columns 2 and a plurality of frames 3 erected on the columns 2. The columns 2 and the frames 3 enclose a columnar space for clamping the casing.

[0026] Specifically, the frame body 1 in this embodiment is the main structure of the casing guide frame, which is built and enclosed by a plurality of vertically arranged columns 2 and a plurality of plane frames. The frame 3 is welded and fixed to each column 2, so that the shape of the frame 3 corresponds to the shape surrounded by the columns 2. This is because the columns 2 are all arranged at the vertex position of the frame 3, that is, the number of columns is equal to the number of frame vertices, which is equal to the number of edges that constitute the frame edge. That is, if there are four columns, a rectangular frame must be matched, and if there are five columns, a pentagonal frame must be matched. The frame provides support for the columns, so that the guide frame itself is a stable structure. The number of columns is at least three, otherwise a closed column cannot be formed, and it is difficult to produce a guiding effect for the cylindrical structure of the casing. Each edge in the same frame is on the same horizontal plane, making the frame flat and firm. There are at least two frames 3, distributed at at least two different heights, so that the columnar space is firm and does not shake itself. If there is only one frame, the column only relies on one fulcrum, which is prone to tilt and deviation, and the frame 1 itself will be deformed, let alone guiding the casing. Therefore, the frame is formed by fixing a plurality of columns 2 and a plurality of frames 3 located in multiple layers from top to bottom to each other, and is a strong and stable column that can withstand vibration.

[0027] Generally speaking, the frame 3 is a rectangular frame, which is respectively arranged at the upper part, the midpoint and the lower part of the column, with a total of three layers to ensure that the column remains vertical; there are four columns 2, which are vertically arranged at the four vertices of the rectangular frame 3; the guide frame formed by the column 2 and the frame 3 is a cubic structure, which has excellent stability and uniform and symmetrical support, and can cope with the shaking in all directions generated when the vibration hammer is drilling.

[0028] In some embodiments, three or five columns 2 are provided, and a triangular or pentagonal frame 3 is enclosed to form a prism structure, which can also maintain good stability. The columns 2 are all arranged at the vertices of the frame 3. Different shape structures can be adjusted according to specific construction environments: for example, in some environments, a triangular structure is more suitable for the terrain, and when the diameter of the casing is too large, a pentagonal frame can be used to visually make it easier to determine the point where the casing is placed.

[0029] In order to make the enclosed frame body 1 more solid, reinforcing rods 6 are provided between frames 3 of different heights. The reinforcing rods can be provided between frames of any different layers and on any side of the frame 1. Generally, in a rectangular guide frame, reinforcing rods are installed on all four sides to maintain the stability of its center of gravity. The reinforcing rod 6 is a scissor brace structure, that is, an X-shaped structure similar to scissors is formed by crossing two steel materials, and is fixed between two frames 3 of different heights as an oblique support. It plays an important role in longitudinal stability and strengthening longitudinal rigidity of the frame. Because the supporting effect of the rectangular structure will deteriorate when the frame reaches a certain height during construction, the addition of scissor braces can transform the structure into a stable triangular structure, thereby improving the bearing capacity of the frame, effectively enhancing the overall stability of the scaffolding, and preventing it from deformation or collapse.

[0030] Furthermore, the frame 3 includes a plurality of limiting holes 4 for the passage of anchor piles. The limiting holes 4 are through holes that vertically penetrate the plurality of frames 3. The limiting holes 4 are located at the apex of the frame 3 for the passage of the anchor piles. Specifically, the limiting holes 4 are located at the apex of the frame 3, and the number of the limiting holes 4 is equal to the number of the columns 2. The limiting holes 4 are opened at the same position on all frames 3 from top to bottom, so that a through hole that penetrates the multi-layer frame can be formed. The diameter of the through hole just matches the diameter of the anchor pile, so that the anchor pile formed on the surface after the anchor rod is anchored into the ground is just confined in the limiting hole. Once the vibrating hammer vibrates or displaces greatly during construction, the anchor pile remains vertical and motionless, and the frame and the entire guide frame will not tilt or vibrate, and remain at the preset point in the constructed state, so that the guide frame remains stable and the casing is accurately positioned.

[0031] The guide frame of the embodiment of the present specification also includes a limit rod 31 provided on the frame 3, and the limit rod 31 connects any two sides of the frame 3. The distance between the intersection of the limit rod 31 and each side and the vertex of the frame does not exceed 1 / 3 of the length of the frame side. The limit rod 31 is an oblique rod connecting two adjacent sides, and its length is shorter than the length of the side of the frame. After forming a rectangular or polygonal frame 3, the limit rod 31 further narrows the space inward, so that when the casing enters the guide frame, the space for left and right deviation is smaller, which makes it easier to align the point. The intersection of the limit rod 31 and the vertex does not exceed 1 / 3 of the length of the side. If the limit rod 31 is fixed at the midpoint of the frame side or further away, it will not only hinder each other, but also affect the entry of the casing. Take the most common square frame as an example: if the limit rod 31 is connected to the midpoint of each side of the frame 3, the oblique rod is just tangent to the edge of the casing, generating friction on the casing, and even damaging the outer wall of the casing. Therefore, the setting of the limit rod needs to maintain a certain distance from the casing, and play a guiding and directing role for the entry and placement of the casing.

[0032] The frame 3 of the embodiment of the specification also includes an adjustment part 5 arranged at the midpoint of each side and facing the casing, and the adjustment part 5 is used to adjust the verticality of the casing. The adjustment part 5 is a support structure that uses threaded steel and bolts to adjust the distance. It is arranged at the midpoint of each side of the frame 3, that is, there are several adjustment parts 5 for several sides of the frame 3, and the adjustable part faces the casing. It is arranged at the midpoint because when the frame 3 is a polygon with a hypotenuse, the midpoint is the position closest to the casing, which can effectively adjust the casing. Each side of the frame 3 is provided with an adjustment part, and a thrust can be applied to the casing in multiple uniform directions. Once the casing tilts during the installation process, the direction of the tilting is observed, so that the threaded steel of the adjustment part 5 in this direction extends to push the casing back to the right position, so that the casing is always kept in a vertical state. In other words, after the casing is smoothly placed in the guide frame, the already stable structure avoids large deviations. Even if there is a slight angle of tilt, the adjustment part 5 can be used for fine adjustment, which further improves the verticality of the steel casing.

[0033] The guide frame also includes a walking ladder 7, and a guardrail 8 is arranged above the walking ladder 7. Since the guide frame is firmly anchored into the stratum by anchor piles, and the frame structure is reasonable, symmetrical, stable and safe, a walking ladder 7 for construction personnel can be arranged for personnel to supervise and deal with various situations when the casing enters the guide frame. In addition, guardrails are added to enhance construction safety.

[0034] The beneficial effects that this embodiment may produce include:

[0035] 1. Use anchor piles to drive into the soil to provide anchoring force for the casing guide frame to ensure that the guide frame does not shift or tip over during the construction of large-diameter pile foundations, thereby improving the verticality of the steel casing, that is, the casing has high accuracy in the vertical direction without obvious inclination or deviation.

[0036] 2. The guide frame structure is symmetrical and stable, with a high safety factor.

[0037] 3. Avoid deviation correction after construction, reduce extra expenses, improve work efficiency, and the guide frame can be recycled and reused, reducing costs.
