Problems solved by technology

[0013] The present invention does not need to drill holes on the cover plate by setting the downward type grouting bottom pipe, which saves the cost and ensures the integrity of the cover plate; in addition, the position of the grouting bottom pipe changes without contact with the inside of the raft. The conflicts in the installation of the reinforced steel structure not only make it easier to advance the project, but also solve the problem of uneven arrangement; again, the bottom pipe of the grouting is no longer located on the raft, and the groundwater in the pipe will no longer be generated before the grouting is closed It will continue to flow upwards, causing serious water accumulation in the basement, which is convenient for subsequent construction; finally, the filling effect is relatively stable

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown, in the existing potting device of the "upward lead method", the grouting bottom pipe 4 runs through the raft 1 and the cover 12 from top to bottom in sequence, and then extends between the cover 12 and the secondary pouring pile top 9 In the pile top space 2, the problem lies in:

[0024] 1. To penetrate the cover plate 12, the grouting bottom pipe 4 must be drilled and welded on the cover plate 12, and the cover plate 12 is a steel plate of one to two centimeters, with high rigidity, and it is difficult to open holes on it, which greatly Increased production costs; the joints welded on the cover plate 12 are not easy to protect during transportation, are easily damaged and deformed, and are not easy to replace, which brings great difficulties to the connection between the grouting bottom pipe 4 and the cover ...

Abstract

The invention discloses a construction device for pile top cavity sealing of a composite pile foundation. When a pile top is secondly poured, a novel grouting bottom pipe and a main rib are welded firmly and poured in the interior of the second pile top, and a pipe mouth is inserted into the interior of a pile top cavity; the novel grouting bottom pipe outside a base pile is embedded in a shallowlayer of foundation soil and is led out the ground by the side surface of a raft plate. Compared with a conventional grouting method, the device can achieve the grouting sealing work on the pile top cavity economically and rationally,can ensure that the integrity of the raft plateis not damaged and the steel bar binding work is smooth while ensuring the grouting effect,reduce engineering costs andimprove work efficiency.

Description

technical field [0001] The invention relates to a construction device for sealing and filling the pile top cavity of a composite pile foundation, in particular to a construction device for sealing and filling the pile top cavity of a composite pile foundation with elastic bearings arranged on the pile top. Background technique [0002] With the vigorous promotion of infrastructure construction in our country, pile foundation, an ancient foundation form, has been widely used and developed unprecedentedly. As one of the main manifestations of pile foundations, piled raft foundations have also developed rapidly in recent years. Pile raft foundations, as the name implies, refer to the foundation form in which piles and caps bear the load of the upper structure together. It has good foundation integrity and high bending rigidity. , wide adaptability and easy to realize pile-soil interaction and other advantages. [0003] The direct rigid connection between piles and rafts in con...
