Double crowded dish stake underground structure that expands that rectangle was arranged

The utility model relates to a double crowded dish stake underground structure that expands that rectangle was arranged belongs to provisional secret support engineering field. The utility model discloses symmetrical arrangement branch and/or load dish in front -seat straight -bar stake, back row straight -bar stake, front -seat straight -bar stake, back row straight -bar stake link together through the rigit -frame beam and form the plane rigid frame, and at the node jia zhituo of back row straight -bar stake with the rigit -frame beam, the front -seat straight -bar stake on the same horizontal direction, back row straight -bar stake couple together through guanliang respectively. The utility model discloses crowdedly expand a dish stake and replace an ordinary straight -bar stake with resistance to compression and resistance to plucking bearing capacity are higher, can increase substantially double row pile supporting construction's antidumping ability. Simultaneously, preceding, back campshed sets up a dis
