Description
Technical field
The present invention relates to a kind of lattice diaphram wall arrangement, belong to Hydraulic and Hydro-Power Engineering and building engineering construction
Field.
Background technology
Diaphram wall has that geological conditions strong adaptability, barrier performance are good, work efficiency is high, short time limit, reliable in quality, economy
High efficiency, environment influence the advantages that small, are widely used at present in hydroelectric project as leakage preventing structure, in work China Democratic National Construction Association and bridge tunnel work
Mainly as foundation pit safeguard structure in journey.In Hydraulic and Hydro-Power Engineering, open caisson is widely used as load-bearing and anti-washing structure, but its is steady
The problems such as qualitative, economy and difficulty of construction, protrudes, using open caisson handle deep alluvion foundation the defects of clearly.In view of
The unique advantage of diaphram wall and the good three-dismensional effect of lattice diaphram wall, lattice diaphram wall is increasingly
It is used as Anti-scouring structure and bearing structure more.Existing construction technology is limited by, in length and breadth the structural type of wall boundary position
Formula and form of construction work are always to perplex the problem of engineering circles.The structural shape of existing lattice diaphram wall mainly includes
" piling wall " pattern and conventional type.Piling wall pattern be in the larger pile body of one section of wall boundary location arrangements in length and breadth, according to
The surrounding in pile body is needed to arrange shaped-steel joint, pile body of first constructing, then " one " font wall section for surrounding of constructing；This structure is lattice
Structure formula continuous underground wall structure is discrete to be embedded in pile body and forms good integrity for pile body with " one " font wall, " one " font wall
Gridiron structure, trenching construction is convenient, and the reinforcing bar cage hoisting of each wall section is convenient, and avoids and occur in vertical wall and cross wall boundary position
The turning for the coating projection easily caved in；The shortcomings that structural shape is the engineering in order to which pile body diameter is more much bigger than thickness of wall body
Investment is higher.Conventional type is that lattice diaphram wall is discrete for " ten " font groove section, " T " font groove section, " L " type groove section
" one " font groove section, it is each section of wall section equal thickness the advantages of this structural shape, quantities is relatively small, construction investment
It is relatively low；Shortcoming is that have the raised turning of the coating easily to cave in, and lattice diaphram wall with cross wall boundary position in vertical wall
The steel bar meter difficulty for four kinds of groove sections being discretely formed is big, and reinforcing bar cage hoisting difficulty is big.
The content of the invention
The technical problems to be solved by the invention are：A kind of lattice diaphram wall arrangement is provided, its structure is whole

Joint insertion outside longitudinal direction within the walls, and is fixedly connected with the longitudinal steel reinforcement cage within the walls in outside, and the end insertion second of horizontal wall is U-shaped
In the cell body of joint, and laterally steel reinforcement cage within the walls is fixedly connected with the second u shaped connector.
It is further：Longitudinal wall also includes the longitudinal wall in centre between inner side longitudinal direction wall, outside longitudinal direction wall, laterally
The side of wall is provided with the 3rd u shaped connector for being used for connecting middle longitudinal wall, the insertion of the 3rd u shaped connector laterally within the walls, and with transverse direction
Steel reinforcement cage within the walls is fixedly connected, the end of middle longitudinal wall is embedded in the cell body of the 3rd u shaped connector, and middle longitudinal direction is within the walls
Steel reinforcement cage is fixedly connected with the 3rd u shaped connector.
It is further：Before horizontal wall is connected, it is equipped with the cell body of u shaped connector, in the cell body of the second u shaped connector
Detachable froth bed, froth bed fill the cell body of full u shaped connector and the cell body of the second u shaped connector respectively；Indulged between in this connection
To before wall, detachable froth bed, the cell body of full 3rd u shaped connector of froth bed filling are provided with the cell body of the 3rd u shaped connector.
It is further：Connecting between u shaped connector and inner side longitudinal direction steel reinforcement cage within the walls, steel reinforcement cage laterally within the walls with
Connecting between the steel reinforcement cage of connection, the second u shaped connector between u shaped connector and outside longitudinal direction within the walls, reinforcing bar laterally within the walls
Connecting between connection, the 3rd u shaped connector between cage and the second u shaped connector and laterally steel reinforcement cage within the walls, middle longitudinal wall
Connection between interior steel reinforcement cage and the 3rd u shaped connector is welding.
The beneficial effects of the invention are as follows：According to the loading characteristic of lattice diaphram wall, armored concrete is made full use of
The characteristics of wall load performance is strong, u shaped connector is introduced in longitudinal wall and horizontal wall, lattice diaphram wall it is discrete for etc.
" one " font groove section of thickness, and the froth bed easily removed can be filled in u shaped connector in advance, to ensure later stage groove section wall
Body is sufficiently close embedded in groove wall in advance, forms more complete stress system.This integrality performance of the structure is good, easy for construction,
The reinforcing bar cage hoisting at each position is convenient, avoids turning for the coating projection that occurs easily caving in cross wall boundary position in vertical wall
Angle, reduce construction risk；Each section of thickness of wall body is identical, and quantities is smaller, reduces construction investment；The use of u shaped connector, without again
Individually processing profiled drill bit construction longitudinal wall and longitudinal wall joint area, and more can guarantee that construction quality, in length and breadth wall
Connection can more be closely linked.
