Description

Technical Field

[0001] The utility model relates to the field of anti-slip pile moulds, in particular to an inner village mould for anti-slip piles with a lower circle and an upper surface and a retaining plate groove. Background Art

[0002] The anti-slide pile-sheet wall structure is a widely used retaining structure, often used in railways, highways, construction, municipal engineering and other fields. The anti-slide pile-sheet wall structure consists of anti-slide piles arranged at a certain distance and retaining plates between piles, and uses the stratum resistance of the anti-slide pile embedded section and the strength of the structure itself to maintain overall stability. As one of the important means of protection against geological disasters such as debris flow and landslide, anti-slide piles have always been an important part of slope management in my country. Due to the convenience and reliability of the existing circular anti-slide pile construction process, the current anti-slide piles are mostly circular cross-section settings, formed in one piece by concrete pouring, or steel pipe piles are used as temporary anti-slide pile foundations. Although rectangular cross-section anti-slide piles have better force strength and anti-slide performance, their complex construction process and construction steps limit the use of rectangular cross-section anti-slide piles. For example, it is difficult to mechanically excavate rectangular holes, which requires manual secondary corrections, the construction of retaining boards is difficult and the cycle is long, the surface of the anti-slide piles is uneven and the surface quality is poor, and the use of rectangular anti-slide piles is limited by the fact that the retaining board slots of the anti-slide pile body are difficult to drill with conventional mechanical equipment and require secondary wet operations.

[0003] In response to the above problems, people have developed a new type of anti-slip pile that can take into account the advantages of construction safety and good anti-slip performance, that is, a combined variable-section anti-slip pile with a circular cross-section embedded section at the bottom and a rectangular cross-section cantilever section at the top. This type of variable-section anti-slip pile can be manufactured based on the construction process of circular cross-section anti-slip piles, which can reduce construction equipment and secondary wet operations. However, the manufacturing process of this type of variable-section anti-slip pile is still relatively cumbersome. When making the upper rectangular cross-section cantilever section pile body, many rectangular baffles are used to surround the steel cage and then pour concrete. After the concrete solidifies and forms, mechanical equipment is used to dig the retaining plate slot on the cantilever section pile body, or the slot is opened through manual secondary operations, which is time-consuming and labor-intensive.

[0004] That is, in view of the problems that the existing variable-section combined anti-slip piles above the lower circle are still difficult to construct and the pile retaining plate grooves are difficult to construct, an inner village mold is proposed to facilitate the construction of the variable-section combined anti-slip piles above the lower circle and the pile grooves. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide an inner lining mold, through which a lower circular upper variable-section anti-slip pile with a retaining plate slot can be manufactured on the basis of the circular cross-section anti-slip pile construction process. The rectangular cross-section cantilever section and the retaining plate slot are integrally formed, which can solve the problems of traditional variable-section anti-slip piles being cumbersome in the manufacturing process, the pile body requiring manual correction, and the pile body retaining plate slot being difficult to construct, thereby reducing the construction difficulty, reducing the requirements for machinery and equipment, and reducing the secondary wet working process.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] An inner village mold for a lower circular upper anti-slip pile with a retaining plate slot, which includes a plurality of cylindrical standard section mold segments for casting to form a rectangular cross-section cantilever section of the anti-slip pile. The standard section mold segment includes at least two mold blocks that can be spliced ​​together to form an internal rectangular space, and plug-in structures that can be plugged into each other are provided at the ends of the mold blocks, and the mold blocks are spliced ​​together through the plug-in structures.

[0008] Furthermore, the mold block is semicircular as a whole, and a semi-rectangular opening is horizontally opened in the middle of the mold block, and a reserved groove for casting to form a retaining plate groove is opened on the inner wall of one side of the semi-rectangular opening, and the reserved grooves on the corresponding mold blocks are symmetrically arranged; the plug-in structure includes a plug-in recess arranged at the side end of one of the mold blocks, and an insertion protrusion used in conjunction with the plug-in recess is provided at the side end of the other mold block.

[0009] Furthermore, fixed through holes vertically connected to the plug-in recess are symmetrically provided at the upper and lower ends of the plug-in recess, and a plug-in hole matching the position, shape and size of the fixed through hole is opened on the insertion protrusion; the plug-in structure also includes a plug-in rod, and the two mold blocks are connected by the plug-in rod passing through the fixed through hole and the plug-in hole.

[0010] Furthermore, a sealing strip for preventing slurry leakage is provided on one side of the insertion hole of the insertion protrusion.

[0011] Furthermore, the reserved groove is a U-shaped structure as a whole, and the reserved groove is arranged on the mold block with the notch facing upward and tilted downward.

[0012] Furthermore, the fixing through hole at the upper end of the plug-in recess is a countersunk hole.

[0013] The beneficial effects of the utility model are:

[0014] 1. The embedded section of the anti-slip pile below the ground is a circular section, and the rectangular section cantilever section above the ground is cast through the "outer circle and inner square" lining mold to form a rectangular section cantilever section and a slot flange. In this way, conventional rotary drilling machinery (circular drill bit) can be used to complete the drilling in one go, which greatly simplifies the construction difficulty. The retaining plate slot and the anti-slip pile cantilever section are cast as a whole at one time, with a firm connection, reliable quality, and convenient and fast construction. The cantilever section is cast in direct contact with the lining mold, and the anti-slip pile surface is high in flatness and quality after casting and forming;

[0015] 2. The lining mold can be customized according to the position and size of the retaining plate slot, and fixed on the steel cage accordingly, and put into the drill hole together. The retaining plate slot and the rectangular cross-section cantilever section of the anti-sliding pile are cast as a whole at one time to avoid secondary concrete wet operation after the pile is formed;

[0016] 3. Through this lining mold, a variable-section anti-slip pile with a lower circle and an upper side with a retaining plate slot can be manufactured based on the construction process of a circular-section anti-slip pile, which can reduce the construction difficulty, reduce the requirements for mechanical equipment, and reduce the secondary wet-working process;

[0017] 4. The retaining plate slot is integrally cast with the anti-slip pile through the lining mold, and is formed in one piece. The retaining plate slot is set on the outside of the anti-slip pile body. Different from the traditional slot set by drilling holes in the pile body, this construction method can reduce the use of mechanical equipment when setting the slot, and can also avoid drilling holes and slots in the pile body;

[0018] 5. The inner mold is set up as a standard section mold segment. By stacking and placing the standard section mold segments, the height of the cantilever section that needs to be cast can be adjusted.

The objectives and other advantages of the present invention can be achieved and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0033] Embodiment 1, as Figure 1-7 As shown, an inner village mold for a lower circular upper anti-sliding pile with a retaining plate slot includes a plurality of cylindrical standard section mold segments 2 that can be stacked and placed on each other for casting to form a rectangular cross-section cantilever section 1 of an anti-sliding pile. The standard section mold segment 2 includes at least two mold blocks 3 with similar appearances that can be spliced ​​together into a cylindrical structure and enclose a rectangular space inside. The ends of the mold blocks 3 are provided with plug-in structures that can be plugged into each other, and the mold blocks 3 are spliced ​​with each other through the plug-in structures. Through this lining mold, a lower circular upper variable cross-section anti-sliding pile with a retaining plate slot can be manufactured based on the construction process of a circular cross-section anti-sliding pile, which can reduce the construction difficulty, reduce the requirements for mechanical equipment, and reduce the secondary wet working process.

[0034] The standard section mold section 2 is formed by splicing two semicircular mold blocks 3. The mold block 3 has a certain height as a whole. A semi-rectangular opening is opened horizontally in the middle of the mold block 3. The semi-rectangular opening can be customized according to the size of the rectangular cross-section cantilever section 1 to be cast. A reserved groove 5 for casting the anti-sliding pile retaining plate slot 4 is opened on the inner wall of one side of the semi-rectangular opening. The setting of the reserved groove 5 can make the retaining plate slot of the pile body integrally formed with it during casting, reducing construction equipment, processes and secondary wet operations. The reserved groove 5 is symmetrically arranged on the corresponding mold block 3; the plug-in structure includes a rectangular plug-in recess 6 arranged at the side end of one of the mold blocks 3, and an insertion protrusion 7 used in conjunction with the plug-in recess 6 is arranged at the side end of the other mold block 3. After the two mold blocks 3 are spliced ​​together, a complete rectangular opening is formed. The mold block 3 is installed with the anti-sliding pile reinforcement cage, and the whole after installation is placed in a pre-drilled pile hole to cast concrete.

[0035] A fixed through hole 8 vertically connected to the plug-in recess 6 is symmetrically arranged at the upper and lower ends of the plug-in recess 6, and the fixed through hole 8 is connected to the outside of the mold block 3. A plug-in hole 9 matching the position, shape and size of the fixed through hole 8 is opened on the insertion protrusion 7; the plug-in structure also includes a plug-in rod 10, which passes through the fixed through hole 8, the plug-in recess 6 and the insertion protrusion 7 in sequence to connect the two mold blocks 3. During installation, the two mold blocks 3 are placed around the steel cage corresponding to the anti-slip pile and assembled with each other. After being fitted, the plug-in rod 10 is passed through to connect the two mold blocks 3. In order to prevent leakage of slurry due to the gap caused by the plug-in rod 10 abutting against the upper standard section mold segment when the upper and lower standard section mold segments 2 are stacked, the fixed through hole 8 at the upper end of the plug-in recess 6 is set as a countersunk hole, and the size of the countersunk hole is consistent with the size of the top end cap of the plug-in rod 10, so that no bulge is formed on the top when the plug-in rod 10 is inserted.

[0036] In order to prevent the concrete slurry from leaking at the connection of the mold block 3, a sealing strip 11 for preventing leakage is provided on one side of the plug-in hole 9 of the insertion protrusion 7.

[0037] The reserved groove 5 is a U-shaped structure as a whole, and the reserved groove 5 is arranged on the mold block 3 with the notch upward and inclined downward. The arrangement of the reserved groove 5 can make the retaining plate slot and the rectangular cantilever section of the anti-slip pile integrally formed during casting.

[0038] The lining mold as a whole can be made of materials such as stainless steel or high-strength plastic steel.

[0039] Embodiment 2, as Figure 8 As shown, on the basis of the above-mentioned embodiment 1, the mold block 3 can also be arranged as two L-shaped structures, and the ends of the mold block 3 of the L-shaped structure are plugged and spliced.

[0040] Embodiment 3, as Fig. 9As shown, based on the above-mentioned embodiment 1, the standard section mold segment 2 can also be formed by four separate mold blocks 3 spliced ​​together. The four mold blocks 3 can be easily stored and installed, and there will be no jamming problem between the mold blocks and the steel cage.

[0041] The use process of this utility model:

[0042] like Figure 6 , 7 As shown, the anti-sliding pile is cast by the steel cage of the anti-sliding pile body and concrete under the constraint of the standard section mold segment 2. The embedded section of the anti-sliding pile below the ground is a circular section, and a corresponding circular steel cage is made. The outer surface of the embedded section of the circular section is directly in contact with the rock and soil; the cantilever section 1 above the ground is a rectangular section, and a corresponding rectangular steel cage is made. The standard section mold segment 2 with "inner circle and outer square" is set section by section outside the rectangular steel cage structure, so that the internal rectangular space of the standard section mold segment 2 fits the rectangular steel cage, and the circular steel cage is connected to the rectangular steel cage. The steel cage of the anti-sliding pile body and the standard section mold segment 2 are integrated. The cantilever section 1 and the retaining plate slot 4 are shaped by the standard section mold segment 2, and the reserved slot 5 is set so that the retaining plate slot 4 and the entire anti-sliding pile body are cast as a whole at one time. The steel cage of the anti-sliding pile body and the standard section mold segment 2 are hoisted together and placed in the punched circular pile hole for casting. After the overall concrete strength of the anti-slide piles reaches the design requirements, the slope earth is excavated layer by layer from top to bottom, and the layer thickness is flush with the height of the retaining board slot 4. After excavating a layer of earth, the retaining board is hoisted and obliquely embedded in the retaining board slot.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
