摘要： PROBLEM TO BE SOLVED: To provide a vertical loading testing method of the directly under ground confirming availability of the directly under ground of a structure without pulling down a foundation of the existing structure.
SOLUTION: A part of a foundation slab coming into contact with the ground surface of the existing structure is separated from the peripheral part in a predetermined size and shape to form a loading slab. A loading testing jack together with a load meter and a displacement meter are installed on the loading slab in an approximately vertical posture to have such a constitution that loading test reaction force is taken in a beam of the existing structure or a slab, and the jack is driven to perform a loading test. After the completion of the loading test, the loading slab is removed to restore the foundation slab, alternatively the loading slab is again combined with the foundation slab to restore the foundation slab.

摘要： PURPOSE:To reinforce the bearing force at the front end without use of a compaction pile. CONSTITUTION:After a concrete body has generated its strength, a compactor 4 having the size and shape equivalent to a compaction pile is inserted in a hide pipe 2 by an intrusion rod 8 to insert to a required depth in the bearing ground to form a hollow 6. The compactor 4 is raised and cement milk is charged into at least the hollow 6. A compacted pile 9 having almost the same shape with the hollow 6 and the sufficient compressive strength to prevent the peripheral ground of the follow from loosening, is inserted in the guide pipe 2 and buried in the position of the hollow 6. While raising the intrusion rod 8, cement milk is charged in the guide pipe 2. Accordingly, a high yield strength cast-in-place concrete pile or the like can be driven by burying an inexpensive compacted pile and the construction cost can be reduced. And the compacting effect at the ground of the front can be securely obtained.

A reinforced concrete post 12 covered with a steel cylinder 12b with a fitting part of beams at the upper part thereof is used as a post. The piles 11 are driven respectively in a number of post positions of an artificial ground. The lower part of the posts 12 is jointed to the upper part of the piles during the driving piles so that the upper ends of respective posts 12 are arranged at a specified level. The ends of respective steel-framed beams 13 are connected to the fitting parts of beams 12b1 12b2, 12b3, of respective posts. PC floor plates 15 are placed on the upper side of respective steel-framed beams 13 and reinforcing rods R3 for the slab are arranged on the upper side of the PC floor plates 15. Concrete C1 is placed at the upper side of the PC floor plates to form a slab 16 made of reinforcing concrete and also concrete is placed in the hollow spaces h3 of respective posts. In this way, forms, supports, etc., are not required and hence, the construction period is reduced.

摘要： PURPOSE:To withdraw a guide pipe simply and quickly to reuse by placing the guide pipe for penetration of a compaction pile into an excavated hole for a cast-in-place concrete pile, etc., and applying a slipping agent to the peripheral surface of the guide pipe. CONSTITUTION:Excavation is made up to the front ground 7 to form an excavated hole 1, and a guide pipe 2 for penetration of a compaction pile 6 is placed into the excavated hole 1. At that time, a slipping agent reducing adhesion with a placed concrete 5 is applied to the peripheral surface of the guide pipe 2, and the peripheral surface of the guide pipe 2 is isolated from the concrete 5. The guide pipe is pulled out after required strength of the placed concrete 5 is exhibited. According to the constitution, the guide pipe is simply and quickly withdrawn to reuse, and a construction cost can be greatly reduced.

摘要： PURPOSE:To prevent muddy water or the like from erupting while a compaction pile is driven in by a method wherein the front end of a guide pipe is shielded watertightly with a covering material equipped with a plurality of cut grooves, and a plurality of such guide pipes are integrally attached to a reinforcing bar basket to be used for construction of a continuous underground wall. CONSTITUTION:A guide pipe 1 is constructed in such structure that the front end thereof is shielded watertightly with a cover 12. A number of cut grooves 15 are formed on the cover 12 so that the grooves extend radially from the center of the cover, and thereby breaking of the cover by driving-in of a compaction pile 2 is made easy. A reinforcing material in upside-down conical shape in 45 deg. inclination is provided to the inside of the guide pipe for making correction to centering of the compaction pile 2 easy. Then a specified number of guide pipes 1 are integrally attached to appropriate positions of a reinforcing bar basket 4 for cast-in-place concrete 3, and are inserted together with the reinforcing bar basket 4 into an excavated hole. Thereby the compaction piles 2 can be driven correctly into point ground and water accompanying excavation and underground water erupting around the compaction piles can be prevented from flowing backward.
