Description

TECHNICAL FIELD

[0001] The utility model relates to pile foundation hole mouth safety protection technical field, concretely relates to a pile foundation hole mouth operation platform. BACKGROUND

[0002] With the vigorous development of highway infrastructure in China, the proportion of bridges is getting larger and larger, and the embedding of the pile casing is necessary when the cast-in-situ bored pile is constructed. After the embedding of the pile casing, the pile casing is in an exposed form before the steel reinforcement cage is placed. In the construction process, a slight carelessness when passing by the hole mouth will cause the worker to fall into the pile casing, which is very dangerous. At the same time, when the pile foundation re-measurement hole position deviation and final hole acceptance are carried out, the surveyor needs to approach the hole mouth to place the prism rod, and a slight carelessness will cause the surveyor to fall into the pile casing, which is very dangerous. Therefore, a safety protection device must be used around the pile casing to make the pile casing no longer in an exposed form, and the main purpose is to improve the safety factor of pile foundation construction.

[0003] The utility model discloses a kind of hexagon assembly type pile foundation hole mouth safety protection devices, and six pieces of horizontal cross brace are connected head to tail to form hexagon, and the horizontal cross brace is connected with the ring at center by several connecting steels, and several steel pipe columns are fixedly connected on the upper end surface of horizontal cross brace, and vertical foot brace is fixedly connected with the corresponding position of steel pipe column on the lower end surface of horizontal cross brace, assembly type pipe sleeve is installed in steel pipe column, and adjacent two assembly type pipes are fixed with assembly type safety protection plate and enclosed to form hexagonal protection structure. Different diameters of ring are selected to be set to different pile diameters, different pile casing diameters of pile foundation construction, and the pile casing is completely isolated, this device not only plays a better safety protection role, but also serves as a safe construction platform. Since the ground around the pile casing is in a concave-convex state, the device is set to the outer periphery of the pile casing, and the device cannot be in a horizontal state. When the operator works on the device, the platform is not stable, and the difficulty will be significantly increased when fine operation or positioning is carried out, which affects the operation speed and accuracy. In addition, the uneven platform can cause the operation equipment or tool to be unstable, increasing the risk of tipping, sliding and the like. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a kind of pile foundation hole mouth operation platform to solve the problems that existing operation platform cannot adapt to the concave-convex ground around pile casing, affect operation speed and accuracy and increase the risk of tipping, sliding and the like.
