【発明の詳細な説明】
この発明は現場打ち基礎杭の構築法に関するものであ〕
、現場打ち杭O載荷試験の九め杭上部と土との摩擦力を
生ぜしめないようにすることを目的とする。[Detailed Description of the Invention] This invention relates to a method for constructing cast-in-place foundation piles.
The purpose is to prevent the generation of frictional force between the upper part of the pile and the soil in the O-loading test of cast-in-place piles.
基礎杭は打ち込まれた所要のものを載荷試験して支持力

1には摩擦力が作用しない状態で載荷試験しうるように
基礎杭を構築することが要望される。The bearing capacity of foundation piles is measured by carrying out a loading test on the required piles driven in.
1 on the desk because it will be cut after rounding the ground excavation for basement floor construction.
1 requires that the foundation pile be constructed so that a loading test can be carried out without any frictional force acting on it.

実施例によって説明する。In order to meet the above-mentioned needs, the present invention has developed a method that can be implemented economically.The details of the S+ will be explained below with reference to the drawings and nine embodiments.

および先端。First, after drilling a hole in the ground, or without digging, the casing 1 is pushed into the ground to a required depth of at least 7 holes. Next, the reinforcing bar cage 2 is inserted into the cooling cage 1. In addition, the cap tire and tip of the rebar gauge.

2の外肯に建込む。All the intermediate sinking needles are attached inside the reinforcing bar cage 2 (not shown).Next, a belt-shaped banking 3 made of foamed synthetic resin such as foamed urethane is wrapped around the outer circumference of the tip, and a thin inner pipe 4 made of corrugated pipe or the like is wrapped around the tip. Inside casing 1, reinforcing bar I1
Built on the outer meaning of 2.

。When the ready-mixed concrete 5 is poured to the bottom of the casing 1, the casing 1 is pulled up approximately 1111@f, and when the casing 1 passes the position of the backing 5, the backing 5 expands], and the ready-mixed concrete reaches the outside 11 of the inner pipe 4.・Next, pour fresh concrete into the inner pipe 4 at the top! ◎ At that time, a backing 6 is also provided at the top to prevent fresh concrete from falling into the junction between the inner pipe 4 and the casing 1.

。試験後はケーシング1を引抜いて再使用する。The concrete is subjected to a hardening vk loading test, and at that time, the casing 1 is left as it is and friction cut is performed. After the test, casing 1 is pulled out and reused.

的に実施できる。With this construction, the casing and circular pipe are used on the top of the foundation pile to ensure the construction of the 7-socket support section.Furthermore, the casing that receives the foundation pile can be pulled out, and the inner pipe Since it is thin-walled, it can be carried out easily.
