Description

Technical Field

[0001] The utility model relates to the technical field of construction of column piles, and specifically discloses a structure for avoiding chiseling the pile head of a column pile. Background Technique

[0002] As a common type of column pile constructed by the bored cast-in-place process, it is widely used in foundation pit support projects. As an important load-bearing component of the support system, it bears the combined action of horizontal and vertical loads. Therefore, the quality of the formed pile directly affects the safety of the support system. After the concrete of the column pile is poured, it is often necessary to chisel the over-poured height of the pile head. The chiseling devices for column piles after concrete pouring are disclosed in Chinese patents CN113605389B and CN113513022B, but it is impossible to control the over-poured height of the pile head during the pouring process, and it is impossible to avoid excessive over-pouring, resulting in low construction efficiency, problems of concrete waste and adverse environmental impacts caused by waste materials. Content of the Utility Model

[0003] The purpose of the utility model is to provide a structure for avoiding chiseling the pile head of a column pile, and solve the technical problems existing in the above background technique.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A structure for avoiding chiseling the pile head of a column pile includes a steel reinforcement cage, a sensing component arranged at the top of the steel reinforcement cage, and an insertion component arranged between the steel reinforcement cage and the sensing component. The steel reinforcement cage includes multiple vertical steel bars. The sensing component includes a sensor and a sensing host, and the sensor and the sensing host are connected by a transmission line. The sensor is fixed on the vertical steel bar of the steel reinforcement cage through the insertion component. The insertion component includes a fixed shell and an insertion block. One side of the fixed shell is provided with a fixed clamp. The fixed clamp includes two semi-circular clamping plates. The arc openings of the two semi-circular clamping plates are arranged opposite to each other. One end of the semi-circular clamping plate is hinged to the side wall of the fixed shell. A connecting ear plate is arranged at the end of the semi-circular clamping plate far from the fixed shell. The connecting ear plates of the two semi-circular clamping plates are connected and fixed by bolts. The fixed shell is fixed on the vertical steel bar of the steel reinforcement cage through the fixed clamp. An insertion groove is formed inwardly on the top side of the fixed shell. The insertion groove is a rectangular structure, and multiple clamping grooves are arranged on the peripheral side walls of the insertion groove. A clamping component is arranged in the clamping groove. The clamping component includes a cushion block, a telescopic rod and a clamping head arranged in sequence from the bottom of the clamping groove to the outside. A compression spring is sleeved on the telescopic rod. The clamping head is a hemispherical structure. The two ends of the telescopic rod are respectively fixed to the cushion block and the flat end of the clamping head. The insertion block is a rectangular block structure adapted to the specification of the insertion groove. Multiple limiting holes are arranged on the peripheral side walls of the insertion block. The specification of the limiting hole is adapted to the specification of the clamping head. The clamping head is clamped with the limiting hole. The sensor is fixed on the insertion block.

[0006] Further, a flexible protective sleeve is sleeved on the outer periphery of the transmission line, and both ends of the flexible protective sleeve are fixedly connected to the sensor and the sensing host respectively.

[0007] Furthermore, the outer plate surface of the connecting ear plate is flush with the arc end surface of the semi-circular clamping plate.

[0008] Furthermore, the clamping grooves on each side wall of the insertion groove are vertically and evenly spaced and stacked, the limiting holes on each side wall of the insertion block are vertically and evenly spaced and stacked, and the distance between multiple clamping grooves is the same as the distance between multiple limiting holes.

[0009] Furthermore, the telescopic rod includes an outer rod and an inner rod, and the outer rod is sleeved on the inner rod and slidably connected to the inner rod.

[0010] Furthermore, through holes are provided on the connecting ear plate.

[0011] Compared with the prior art, the present utility model has the following characteristics and beneficial effects:

[0012] By arranging a sensing component at the top of the steel reinforcement cage in the present utility model, when the concrete reaches the position of the sensor during the pouring process, the sensing host gives an alarm prompt and stops the concrete pouring. The over-pouring height can be freely adjusted, which is beneficial to controlling the pile length, accurately controlling the pile head elevation, avoiding the chiseling work caused by subsequent concrete over-pouring, reducing concrete waste, and avoiding the impact of waste on the environment. The construction efficiency is comprehensively improved. By arranging a plug-in component for installing the sensing component on the steel reinforcement cage between the steel reinforcement cage and the sensing component, when it is necessary to slightly adjust the height of the sensor before concrete pouring, the transmission line is pulled upward, and the clamping head is misaligned and clamped with the limiting hole, so as to slightly adjust the height of the sensor. Thus, while stably fixing the sensor, the pouring height can be controlled more precisely. After the pouring is completed, the sensor is pulled out upward with force and cleaned, and then it can be reused, increasing the turnover utilization rate. It has the characteristics of safety and applicability, has good promotion and practical value, and will produce good economic benefits after extensive promotion and application.
