[0036] Such as Figure 1 to Figure 5 As shown, a buried construction prefabricated pile delivery device of the present invention includes a clamp 1 and at least one clamping block 2, and the upper part of the clamp 1 is provided with a connecting arm 11 that can be connected with the drill pipe of the pile driver. And the lower part of the hoop 1 is provided with a hoop hole 12 that can match the outer peripheral surface of the embedded construction prefabricated pile. The hoop hole 12 extends to the middle of the hoop 1; The upper part of the hole 12 is formed with a clamping groove 13 that can be fitted with the clamping block 2. The upper part of the embedded construction prefabricated pile extends into the hoop hole 12 and rotates, and the clamping block 2 is clamped in the clamping groove 13, so that the embedded Type construction prefabricated pile is fixedly matched with clip 1.

[0037] In the embodiment, the number of clamping blocks 2 is four, and correspondingly, t...

[0053] The quantity of the card block 2 is one. The center of the clamping block 2 is located on the axis of the pile, so when sending the pile, the pile will not be inclined due to the weight. The parts not described are the same as the first embodiment.

[0054] The invention has the advantages of being able to implant the embedded construction prefabricated pile into the pile hole, reliable operation and simple structure.

Abstract

The invention discloses an embedded construction prefabricated pile following device, which comprises a hoop and at least one clamping block. A connecting arm which can be connected with a drill pipe of a pile machine is arranged at the upper part of the hoop. A hoop hole which is matched with the outer circumference of an embedded construction prefabricated pile is arranged at the lower part of the hoop and extends to the central part of the hoop. The clamping block is fixedly arranged at the top of the embedded construction prefabricated pile. A clamping groove which can be in embedded fit with the clamping block is formed at the upper part of the hoop hole. The upper part of the embedded construction prefabricated pile stretches into the hoop hole and is rotated to clamp the clamping block into the clamping groove, so that the embedded construction prefabricated pile is fixedly matched with the hoop. The embedded construction prefabricated pile following device solves the problem in following the embedded construction prefabricated pile when the embedded construction prefabricated pile is used, and has the advantages that the embedded construction prefabricated pile can be embedded in a pile hole and the pile can be accurately followed to designated depth at the same time; and the construction management becomes easy, clear and simple.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to the construction technology of embedded construction prefabricated piles, in particular to an embedded construction prefabricated pile sending device and a method for sending piles. Background technique [0002] Engineering piles are piles that are used in engineering and ultimately act as forces in buildings and structures. Engineering piles are piles used on engineering entities to bear certain loads. [0003] At present, there are mainly three methods for foundation pile construction: hammering type, static pressure type and embedded type. Hammering and static pressure are the construction techniques for general construction of prefabricated piles, and embedded piles are generally poured concrete piles on the construction site. When hammering or static pressure construction prefabricated piles send piles, use the prepared steel sleeve to directly send the pr...
