Description

Technical Field

[0001] The utility model relates to the technical field of cast-in-place pile construction, and more specifically to the technical field of a novel quick-install cast-in-place pile combined template. Background Art

[0002] A bored pile is a type of pile made by drilling a hole in place and pouring concrete or reinforced concrete. Commonly used methods include: (1) bored piles: piles are made by drilling a hole in place and pouring concrete using a spiral drill, a submersible drill, etc. There is no vibration or soil squeezing during construction, but the pile settlement is slightly larger. Spiral drills are suitable for clay, sand, and artificial fill above the groundwater level. The drilled soil rises along the spiral blades on the drill rod and is discharged out of the hole. The hole diameter is about 300mm, and the drilling depth is 8 to 12m. The drill rod is selected according to the soil quality and water content. Submersible drills are suitable for drilling clay, sand, silt, and silty soil, especially in soil layers with a high groundwater level. Mud is used to protect the wall during drilling to prevent the hole from collapsing. (2) pipe-sinking piles: a steel pipe with a reinforced concrete pile shoe (pile tip) or a flap-type pile shoe is sunk into the soil by hammering or vibration, and then concrete is poured and the pipe is pulled out to form a pile. Piling that uses hammers to sink and pull out pipes is called hammer-driven cast-in-place piles; vibrating piles that use a vibrator to sink and pull out pipes are called vibration-driven cast-in-place piles. This method of pile construction is prone to problems such as broken piles, necking, hanging piles, and water and mud ingress into the pile shoe. During construction, careful inspections and timely treatment are recommended. Alternatively, there are explosive-expansion cast-in-place piles that use explosives to create an enlarged head at the bottom of the pile hole to increase bearing capacity.

[0003] The amount of cast-in-place piles in photovoltaic projects is large, and single-layer fixed-size formwork is usually used. Most formwork heights are above 500mm, and the two formwork sheets and the upper and lower layers of formwork are mostly connected by bolts. The existing technology and the above patents have the following problems:

[0004] 1. The amount of bored pile work in photovoltaic projects is large, and the template bolt connection is time-consuming and inefficient.

[0005] 2. When the terrain has large elevation differences, the height difference between the traditional double-layer formwork and the single-layer formwork is too large, and the height difference between two adjacent piles is often also large, often exceeding the freely adjustable height of the bracket. Additional construction measures (difficult to implement) or increasing the freely adjustable height of the bracket during design (uneconomical) are required to ensure that the height difference between the pile tops meets the bracket installation requirements. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned technical problems and provide a novel quick-install cast-in-place pile combination formwork. The novel quick-install cast-in-place pile combination formwork in this utility model can adjust the height difference of the pile tops of a group of piles by adding or removing formwork, and can be quickly installed without bolts.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] The utility model provides a novel quick-install cast-in-place pile combination template, comprising cast-in-place pile template units that can be detachably spliced ​​from top to bottom, each cast-in-place pile template unit comprising a left installation template and a right installation template that are symmetrically arranged, and mutually embedded interlocking parts are provided at the matching positions of the left installation template and the right installation template, and the left installation template and the right installation template form a hollow template through the interlocking parts.

[0009] Specifically, only the left installation template and the right installation template need to be produced during mass production. During installation, the left installation template and the right installation template are combined together to form a complete cylindrical template. Two or more sets of cast-in-place pile template units are combined longitudinally to form a raised cylindrical template.

[0010] In one embodiment, the left mounting template is a left semi-arc template, and the tops of the two side walls of the left semi-arc template close to the right mounting template are both provided with left engaging grooves, the bottoms of the two left engaging grooves are left positioning blocks, and the tops of each left positioning block are provided with positioning columns.

[0011] In one embodiment, the positioning column is axially arranged in the left fitting groove, and the top of the positioning column extends out of the corresponding left fitting groove; the bottom of the left positioning block is provided with a first positioning hole that cooperates with the corresponding positioning column of another cast-in-place pile template unit.

[0012] In one embodiment, the right mounting template is a right semi-arc template, and the right semi-arc template is provided with a right interlocking groove at the bottom of the two side walls close to the left semi-arc template. The top of the two right interlocking grooves is a right positioning block, and each right positioning block is provided with a second positioning hole that cooperates with the corresponding positioning column.

[0013] In one embodiment, each left positioning block is inlaid and matched with the corresponding right embedding groove, and each right positioning block is inlaid and matched with the corresponding left embedding groove.

[0014] In one embodiment, a right positioning card is provided on the outer side of each right positioning block.

[0015] In one embodiment, the right positioning card is a square block, the length direction of each square block is along the axial direction, and the square block partially extends out of the top of the right positioning block.

[0016] In one embodiment, a left positioning card is provided on the outer side of each left positioning block.

[0017] In one embodiment, the left positioning card is two bar-shaped blocks. Each right positioning card is inlaid with the corresponding left positioning card, and each right positioning card is inlaid with the corresponding left positioning card.

[0018] In one embodiment, the number of cast-in-place pile formwork units is two.

[0019] In one embodiment, the number of cast-in-place pile formwork units is four (two or more).

[0020] In one embodiment, the height of the cast-in-place pile formwork unit is 280 mm to 350 mm.

[0021] This solution has a stable structure and can be quickly installed and disassembled. The height of a single-layer cast-in-place pile template unit can be reduced to about 300mm. The height of a single pile can be adjusted by stacking multiple layers of cast-in-place pile template units to control the height difference of the single pile.

[0022] The beneficial effects of the utility model are as follows:

[0023] 1. The utility model has a reasonable design.
