Problems solved by technology

[0004] This method has the following disadvantages: 1. The removal speed is very slow and the dust is relatively large, which affects the health of workers and the environment
2. It is difficult to control the strength of the pile body during demolition. If the strength is too high, the demolition efficiency will be affected, and if the strength is too low, the integrity of the pile body will be affected.
3. The length of breaking is greatly affected by the skills of workers, which increases the cost of the project
4. Long-term demolition has a great impact on the quality of the pile body

Embodiment 1

[0028] Such as figure 1 As shown, in this embodiment, the pile pouring structure based on information technology includes a reinforcement cage, a limit ring 3 installed on the outside of the reinforcement cage, several PVC pipes 6 arranged in the reinforcement cage, and a plurality of PVC pipes 6 arranged on the limit ring 3 The cut-off layer 5 on the top and the two-dimensional code display board 7 set correspondingly with the steel cage one by one, the cut-off layer 5 is ring-shaped, and the two-dimensional code display board 7 is provided with a two-dimensional code that enters the input information interface after scanning.

[0029] During construction, build a BIM model according to the design requirements, excavate pile holes and make a steel cage of suitable size according to the BIM model, install the limit ring 3 at the corresponding position of the reinforcement cage, and install the cut-off layer 5 on the limit ring 3 , the part above the cut-off layer 5 is the desi...

Embodiment 2

[0035] On the basis of the above embodiments, in this embodiment, the cut-off layer 5 is provided with several long holes through which the PVC pipe 6 can pass. Utilize the long holes to allow structures such as PVC pipes 6 and steel bars to pass through, so as to avoid interference between the cut-off layer 5 and the reinforcement cage.

[0036] The blocking ring 3 is used to support the cut-off layer 5 to enhance the stability of the cut-off layer 5 and prevent the cut-off layer 5 from being displaced or deflected by the impact of concrete.

[0037] In this embodiment, the cut-off layer 5 is connected to the limiting ring 3 through fasteners. In this way, the connection strength between the cut-off layer 5 and the limiting ring 3 is improved.

[0038] In this embodiment, the limit ring 3 is a steel ring. In order to ensure the strength and stability of the limit ring 3 itself, the limit ring 3 can also be retained in the cast-in-place pile 1 as a part of the pile structure...

Embodiment 3

[0043] On the basis of the above embodiments, in this embodiment, brazing pre-embedded pipes 8 are installed on the reinforcement cage plate. In this embodiment, the pre-embedded steel pipe 8 is located above the cut-off layer 5. After the concrete pouring is completed, the pre-embedded steel pipe 8 is pre-embedded in the pile head part. The pre-embedded pipe 8 is used as the installation basis, and the pile head is hoisted to facilitate the transfer of the pile head. In this embodiment, the pre-embedded steel pipe 8 is arranged above the center of gravity of the pile head, so as to avoid unnecessary deflection and shaking of the pile head during hoisting.

[0044] In this embodiment, the brazing pre-embedded pipe 8 is sealed with a sealing plug. The two ends of the pre-embedded steel pipe 8 are blocked by the sealing plug, and when pouring concrete, it is possible to prevent the concrete from entering the pre-embedded steel pipe 8 and affect the use of the pre-embedded steel...

Abstract

The invention discloses a pile casting structure based on the informatization technology, a pile structure and a pile head breaking method. The pile casting structure comprises reinforcement cages, limiting rings installed on the outer sides of the reinforcement cages, a plurality of PVC pipes arranged in the reinforcement cage, cut-off layers arranged on the limiting rings and two-dimensional code display boards arranged in one-to-one correspondence with the reinforcement cages, wherein the cut-off layers are annular, and two-dimensional codes which enters an information input interface afterbeing scanned is arranged on the two-dimensional code display boards. The pile casting structure has the beneficial effects that the pile body strength information is input by scanning the two-dimensional codes, informatization management is achieved in the pile construction process, the working efficiency is improved, the cut-off layers can be used as an interface between the pile bodies and pile heads, and therefore the portion needing to be broken is rapidly positioned, the pile heads on the upper portion of the cut-off layers are broken, the cut-off layers can protect the lower structure,and damage to the part below the cut-off layer is reduced in the breaking process.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a pile pouring structure, a pile structure and a pile head removal method based on information technology. Background technique [0002] Cast-in-situ piles are frequently used in various projects. In the case of general inspection, changes in pile diameter, difficulty in statistics of construction information, and low efficiency of breaking pile heads are one of the factors that delay the construction period. How to ensure the timeliness and efficiency of pile breaking is the key, and it is also the research focus of avoiding the influence of pile body quality, improving pile breaking methods, and reducing labor input. [0003] To break the cast-in-situ pile head, the conventional method is to use a pneumatic pick to break it manually. After the concrete strength reaches 70%, excavate the soil between the piles. Workers use pneumatic picks to break the piles according to t...
