Abstract
The utility model belongs to the technical field of the tubular pile construction and specifically relates to a exempt from back cover stake point for tubular pile construction, including the stake point, the stake point includes bottom sprag and fixed plate, and the bottom sprag is divergent distribution around same center by the polylith riser, and on the bottom sprag was arranged in to the fixed plate, the center of fixed plate was provided with flexible material package. The utility model discloses an installation flexible material package avoids the adverse factor of back cover concrete placement in-process, promotes the shutoff effect of tubular pile.
Description
Technical Field
The utility model belongs to the technical field of the tubular pile construction and specifically relates to a exempt from back cover stake point for tubular pile construction.
Background
The prestressed concrete pipe pile is widely applied to the fields of civil buildings, municipal administration, metallurgy, ports, highways and the like, particularly in Yangtze river delta and Zhujiang delta areas, and the prestressed pipe pile is quite common in use due to the fact that geological conditions are suitable for the use characteristics of the pipe pile. According to the design specification requirement, in the prestressed pipe pile construction process, when a first section of pipe pile is constructed, bottom sealing concrete needs to be poured, so that the strength of the pipe pile is increased on one hand, and on the other hand, the water gushing on the underground water can be prevented.
However, the length of the tubular pile is often more than 8m, when the bottom sealing concrete pouring is carried out on the first section of tubular pile according to the traditional method, the phenomenon of concrete segregation is very easy to occur in the pouring process, not only materials are wasted, but also the construction quality is influenced, and the process of pouring the bottom sealing concrete is very inconvenient for the tubular pile construction.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a back cover stake point exempts from for tubular pile construction, and aim at solving the concrete pouring tubular pile back cover department and appear the condition that the concrete isolated easily, guarantee the normal clear of construction, improve construction quality simultaneously.
The utility model adopts the following technical scheme:
the utility model provides a exempt from bottom sealing stake point for tubular pile construction, includes the stake point, and the stake point includes bottom sprag and fixed plate, and the bottom sprag is the divergence by polylith riser around same center and distributes, and the fixed plate is arranged in on the bottom sprag, and the center of fixed plate is provided with flexible material package.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a there is stake point and the combination of flexible material package, flexible material package can effectively carry out the effect of back cover water shutoff to the tubular pile, promotes the shutoff effect, guarantees construction quality.
Further, the utility model discloses a preferred scheme is:
the outside of flexible material package is soft fabric, and inside is for meeting water sclerosis material.
The water hardening substance is a mixture of cement, sand, coarse aggregate and an expanding agent.
The bottom support is formed by splicing four vertical plates.
The position that the fixed plate is close to the outer edge is provided with the rivet around flexible material package.

Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
A bottom sealing-free pile tip for pipe pile construction mainly comprises a bottom support 1 and a fixing plate 2. The bottom sprag 1 is that the riser 11 by the same specification of polylith is the divergence around same center and distributes, and in this embodiment, bottom sprag 1 is provided with four risers 11, and every riser 11 is the cross structure distribution around same center respectively. Fixed plate 2 is the circular slab, and the diameter of fixed plate 2 is greater than the external diameter of tubular pile, and fixed plate 2 arranges the top of bottom sprag 1 in and fixed plate 2 and bottom sprag 1 fixed weld.
The central point of fixed plate 2 puts and is provided with flexible material package 3, and the outside of flexible material package 3 is soft fabric as the inclusion, and flexible material package 3 is inside for meeting the mixture of water hardening material, concrete cement, sand, coarse aggregate and expanding agent.
The position circumference that fixed plate 2 is close to outer edge is provided with rivet 4, and rivet 4 is around 3 evenly distributed of flexible material package.
This embodiment is when using, in the static pressure stake work progress, before the pushing down of first section tubular pile 5, at first fill in the inside of first section tubular pile 5 with flexible material package 3, then through rivet 4 on the fixed plate 2 with fixed plate 2 and tubular pile 5 temporary connection, then be connected the stake point with tubular pile 5 through the welding and fix. After the construction of the tubular pile 5 is completed, water is poured into the pile hole, water flows into the flexible material package 3 at the moment, cement, sand, coarse aggregate, an expanding agent and the like in the flexible material package 3 are hardened in the presence of water, and the bottom of the tubular pile 5 is blocked.
The utility model discloses an install in advance, avoid falling back cover concrete pouring in-process adverse factor, promote the shutoff effect of 5 back cover concrete of tubular pile and improve building engineering's entity quality.
The above is only the concrete embodiments of the present invention, but the protection of the present invention is not limited to this, and all the equivalent changes or replacements proposed to the technical features of the present technical solution, which can be considered by those skilled in the art, are included in the protection scope of the present invention.
