Further, the vertical drain is sand wick;
Further, pinniform horizontal drainage channel includes main pipeline and lateral, and the main pipeline is in periphery On according to blossom type distribution drill through the floral tube of hole, the lateral is connected to by described hole with the main pipeline;
Further, pinniform horizontal drainage channel using steel pipe, iron pipe, pvc pipe, plain concrete pipe, without sand coagulation One kind in native pipe, plastic whorl hose, steel wire Water penetrative flexible pipe and underground blind ditch material;
Further, the vacuum extractor uses one kind of powerful vacuum pump, jet pump and deep well submerged pump;
Further, it is described vacuumize supervisor be connected to the vertical drain by conduit coupling;
Further, the conduit coupling is made of flexible rubber hose;
Further, the diaphragm seal is using one kind in polyethylene or polyvinyl fluoride;
Further, the gas injection device uses one kind of air compressor, high-pressure pump and vapour booster pump.
Compared with prior art, the advantageous effects of the utility model:

Fig. 2 is the structural plan schematic top plan view of the utility model;
Reference sign:1, foundation soil body;2, vertical drain;3, pinniform horizontal drainage channel;4, vacuum means It sets;5, supervisor is vacuumized;6, diaphragm seal;7, gas injection device;8, air injection pipe;9, conduit coupling.
Specific implementation mode
As illustrated in fig. 1 and 2, a kind of vacuum method pinniform horizontal drainage structure, including drainage system, sealing vacuumize and are System and gas recycling system;
In the present embodiment, the drainage system includes that the vertical drain 2 being arranged in foundation soil body 1 and pinniform are horizontal Drainage channel 3;Pinniform horizontal drainage channel 3 include main pipeline and lateral, the main pipeline be on the outer periphery according to Blossom type is distributed the floral tube for drilling through hole, and the lateral is connected to by described hole with the main pipeline;The pinniform water The multilayer in the foundation soil body 1 of flat raft aquaporin 3 is arranged, and is connected to the vertical drain 2.It uses in the prior art Medium coarse sand is higher as drainage blanket cost, in the sand and stone resources scarcity territorial restrictions applicability of vacuum method;Existing skill There is horizontal drainage range in foundation soil body involved by vertical drain 2 described in art (sand wick or plastic draining board) Limit is needed to set a large amount of vertical drain 2, be can be only achieved expected within the scope of certain Soft Ground Construction requirement.The utility model is not necessarily to sand bedding course, and the multilayer in the foundation soil body 1 of pinniform horizontal drainage channel 3 is arranged, The draining range contacted with the soil body is considerably increased in pinniform arrangement in level, and then reduces the vertical drain 2 Quantity greatly reduces engineering cost;
The sealing pumped vacuum systems includes vacuum extractor 4, vacuumizes supervisor 5 and diaphragm seal 6;The diaphragm seal 6 covers It is placed on the foundation surface 1, described 5 one end of supervisor that vacuumize are connected to the vacuum extractor 4, and the other end is connected by pipeline The connection of part 9 and vertical drain 2;
