Description
TECHNICAL FIELD
[0001] The utility model relates to the field of cast-in-place pile construction technology, and particularly relates to a supporting device for cast-in-place pile pouring guide pipe installation. BACKGROUND
[0002] In building engineering, especially in the case of high bearing capacity requirement and complex geological conditions, cast-in-place piles are constructed in the foundation pit. Before the foundation pit is excavated, a steel casing is driven into the original ground. After the steel casing is vibrated into place by a vibrating machine, the position of the bottom surface of the steel casing is the position of the bottom surface of the foundation pit. After the silt in the steel casing is removed, a pouring guide pipe is installed for pouring. For cast-in-place pile construction in super-thick sand layers, the traditional cast-in-place pile construction method faces many challenges due to the special geological conditions. Specifically, the following problems exist:
[0003] First, the pouring guide pipe vibration problem: super-thick sand layers have high permeability and low cohesion, which makes any disturbance during construction likely to cause instability of the stratum, thereby affecting construction quality and efficiency. During the pouring of cast-in-place piles, the vibrations generated by pouring equipment (such as concrete pump trucks and vibrators) can be transmitted to the surrounding sand layer. Due to the loose structure and easy movement of the sand layer, under the action of vibration, it will be directly transmitted to the pouring guide pipe through the fixing device of the pouring guide pipe, causing the guide pipe to vibrate with a large amplitude. For super-thick sand layers, this vibration effect is particularly pronounced, because the instability of the sand layer easily amplifies the influence of vibration, and a large vibration amplitude of the pouring guide pipe will adversely affect the pouring operation.
[0004] Second, the operation surface limitation: there is often not enough operation space around the opening of the steel casing, making it difficult for the operating personnel to effectively complete the installation and removal of the guide pipe. This not only increases the construction difficulty, but also negatively affects the construction efficiency.
[0005] Third, the lack of safety protection: after the pouring of cast-in-place piles in the steel casing is completed, the top of some cast-in-place piles may be lower than the original ground, and the upper part of the steel casing is empty and not poured. If effective protective measures are not taken in time at the opening of the steel casing, there is a high risk of accidents, such as personnel falling into the steel casing hole, causing personal injury accidents. This not only threatens the safety of the personnel on site, but also may delay the progress of the entire project.
[0006] In summary, the current technology and equipment are obviously unable to fully meet the actual engineering requirements in view of the above-mentioned problems existing in the construction process of cast-in-place piles in super-thick sand layers. Especially, while ensuring construction quality and improving work efficiency, the safety of the construction site also needs to be ensured, which is one of the key problems to be solved at present.
