Load Transfer System
This is a new type of pile foundation for support of structures. It uses a new method of forming concrete around the steel rebar prior to installing the rebar. Concrete is molded in an undulating fashion to improve load transfer to the adjacent hole backfill. The backfill is densified in place and grouted to maintain the dense configuration. The grouting is injected into an unlined hole. If temporary casing is used during drilling, it is removed prior to grouting. The basic premises are that grouting the hole backfill to the surrounding soil provides a better load transfer at that interface. And, beyond a few inches past the steel rebar, grouted dense sand and gravel are adequate for the load at that point. Timing of the grouting is more flexible than typical ready-mix concrete delivery systems. This method also allows for real time testing of the pile capacity.

Water Intake Pipeline Structure Passing Through Soft Foundation Embankment Below Flood Level and Construction Method
The present invention discloses a water intake pipeline structure passing through a soft foundation embankment below a flood level and a construction method. The water intake pipeline structure comprises: pipelines, a gate valve well, a concrete pipe bed, a high-pressure jet grouting pile continuous wall, cement deep mixing piles, geogrids, backfilling clay, a clay bound macadam and concrete key walls. After the embankment is broken and excavated to reach a pipeline embankment-passing design elevation, the cement deep mixing piles are fully disposed in a plum blossom type, and the high-pressure jet grouting pile continuous wall is disposed under the gate valve well. A plain concrete cushion layer, the gate valve well, the concrete key walls and the concrete pipe bed are poured, the water intake pipelines are installed, and the pipelines behind the gate valve well are wrapped with concrete. The geogrids are placed during clay backfilling, and layered soil filling is performed. An embankment top is restored by using the clay bound macadam. The gate valve well is provided with a gate valve, and an operating lever is connected onto the gate valve. The present invention further discloses the construction method of the water intake pipeline structure designed to pass through the soft foundation embankment below the flood level. The present invention can eliminate differential settlement of an embankment-passing section, cut off seepage channels in contact positions of the pipelines and the embankment body, and improve the anti-skid stability of an embankment slope, and meanwhile it is novel in structure and convenient to implement.
