preparation example Construction

[0044] Present embodiment is the preparation of short pile, and its production process mainly comprises the following steps:

[0045] The first is the preparation of raw materials. The prestressed main reinforcement 1 is made of prestressed steel rods, and the common main reinforcement 2 is made of hot-rolled grade III steel bars, which are connected with the stirrup 3 by roll welding to form a reinforcement cage; the end plate 5 and the skirt 6 are welded to form a pile cap The short tube 7 is connected with the end plate 5 by welding; the anchor rib 8 penetrates the anchor rib anchor hole 10 on the end plate 5 and is fixed on the end plate.

[0046] Install the pile cap at the end of the reinforcement cage, penetrate the prestressed main reinforcement 1 of the reinforcement cage into the anchorage hole 9 of the prestressed main reinforcement on the end plate 5, and realize the connection between the reinforcement cage and the pile cap; install the tail plate 16 at the end of ...

Embodiment 2

[0056] Such as Figure 6 As shown, the present invention can also be used in Figure 6 The concrete round pile with lifting lug is provided with lifting lug, and when making the concrete round pile with lifting lug, the end plate 5 is a solid disc shape. The position of the lifting lug is determined according to the length of the pile and the way of hoisting. In this embodiment, the two-point hanging method is adopted, and the lifting lugs 24 are ring-shaped, and there are two sets, and the distance from the pile end is 0.207L, where L is the length of the pile body.

[0057] Prestressed main reinforcement 1, ordinary main reinforcement 2 and stirrup 3 are connected by roll welding to form a reinforcement cage; the lifting lugs are fixed on the reinforcement cage by binding.

[0058] When the reinforcement cage with the pile cap, tail plate 16 and tension link plate 17 installed is placed in the lower mold 12, attention should be paid to making the lifting lug 24 in the top ...

Embodiment 3

[0061] When making the cross section of the pile body as a standard circle, please refer to Figure 7 , can be produced by adding a cover plate 25, the size and shape of the upper cover plate 25 are consistent with the intersecting line between the bottom of the chute 14 and the upper mold 13.

[0062] After the cloth forming process, take out the cutting trough 14, put the upper cover plate 25 vertically into the feeding port on the top of the upper mold 13, and apply pressure properly so that the upper cover plate 25 is in close contact with the upper mold 13.

[0063] All the other are identical with embodiment 1, no longer repeat.

Abstract

The invention provides a concrete circular pile and a method for processing the concrete circular pile. The concrete circular pile comprises a plurality of pre-stressed main ribs and a plurality of ordinary main ribs which are arranged circularly at intervals, wherein at least one circle of hooping is helically wound outside the pre-stressed main ribs and the ordinary main ribs; the pre-stressed main ribs, the ordinary main ribs and the hooping are inserted into concrete of a pile body along a longitudinal axis; the two ends of the concrete circular pile are provided with an end plate and a pile cap consisting of a skirt; the pre-stressed main ribs are fixed with the end plate; and the end plate is connected with a short pipe which is provided with a sealing head at one end and is inserted into the concrete of the pile body. The concrete circular pile provided by the invention has the advantages of large vertical bearing force, large pile foundation bearing force and capabilities of realizing mechanization and increasing the production efficiency.

Description

technical field [0001] The invention relates to the construction field, in particular to a concrete round pile and a processing method thereof. Background technique [0002] Cement concrete products are widely used in the field of construction, such as ports, municipalities, bridges, railways, highways, water conservancy and other projects. As a major category of cement concrete products, precast concrete piles are developing rapidly. [0003] At present, there are mainly the following types of piles in concrete piles. The first type of concrete pipe piles is produced by centrifugal process molding, atmospheric pressure steam curing and / or high pressure steam curing systems, from concrete mixing to prestressed high-strength concrete Pipe piles can be completed within 24 hours from the autoclave, and the production efficiency is high. A single production line can produce 3000 meters of piles per day. [0004] The second type is cast-in-situ piles, which are pile holes formed...
