Description
Technical field
This utility model relates to superweak saturated soft clay secondary consolidation drainage arrangement, belongs to Soft Soil Subgrade Treatment Techniques field.
Background technology
To soft soil foundation definition, highway industry specification refers to that intensity is low, the soft layer that decrement is higher, most containing certain organic substance.Japan's design of high-level highway specification is defined as: the soil layers such as the main mollisol many by the fine particle content such as clay and silt, organic soil, peat and the loose sand that hole is big are constituted.Level of ground water is high, embankment thereon and structure poor stability and the ground of generation sedimentation.Soft soil foundation is also classified by Japan's specification, it is proposed that type outline criterion.Point out when providing soft soil foundation definition: soft soil foundation can not only be determined by foundation condition simply, different because of embankment shape and Construction Condition, it is necessary on the basis of fully research embankment and the kind of structure, form, scale, foundation property, it may be judged whether should be by Soft Ground.The purpose of soft soil roadbed process is to improve stability and the bearing capacity of this section of highway subgrade.
The processing method of soft soil foundation has many, such as sand material displacement method, cement mixing method for strengthening, preloading and vacuum method etc.；These methods can realize the consolidation of soft soil foundation, but it is relatively slow all to there is consolidation rate, the defect that cost is the highest.Such as: preloading and vacuum method are required to arrange pumping equipment, laying sand bedding course, after consolidation, ground there will be bigger sedimentation, sandstone is needed again to backfill after sedimentation, cost is high, and is sometimes easily subject to the restriction of sandstone material, and some areas lack sandstone.Both approaches is accomplished that the consolidation of vertical direction, and applicant thinks that we can start with from horizontal direction consolidation, and the apparatus and method finding easy material saving solve above-mentioned problem.
Summary of the invention
The purpose of this utility model is the problem existed for prior art, proposes superweak saturated soft clay secondary consolidation drainage arrangement, this bracing means can recycled for multiple times, and there is extraordinary consolidation effect, it is easy to implement, can use with large-scale promotion.
Technical solutions of the utility model are as follows: superweak saturated soft clay secondary consolidation drainage arrangement, including support bar, are provided with motor inside described support bar, and described support bar end is provided with the drill bit that is connected with motor；Several swelling gasbags being connected by connector it are provided with support bar outside described support bar；Several expansion links it are additionally provided with inside described support bar；Connect on described swelling gasbag and have gas tube；Described gas tube is connected with force (forcing) pump.
Gas tube described in the utility model is provided with sealing block with the junction of swelling gasbag.Described swelling gasbag uses three-decker, including hydrophobic layer from outside to inside, the first rubber layer and the second rubber layer；Gluing connecing is used between described hydrophobic layer, the first rubber layer and the second rubber layer.Separated by connector between described adjacent swelling gasbag, and be connected with support bar by connector.Described swelling gasbag is a diameter of 3-5cm under unaerated state；Described swelling gasbag a diameter of 60-200cm in the deflated condition.Described bit face is provided with spiral salient lines；Described drill bit is conical structure, a diameter of 10-25cm of conical top surface.
The beneficial effects of the utility model: this utility model is provided with support bar, support bar is built-in with motor, and the end of support bar is connected by motor drill bit, support bar can pierce soft soil foundation the most easily, it is achieved the placement of support bar；The outside of support bar is provided with several swelling gasbags, opens swelling gasbag after support bar is placed in weak soil basic unit, and the moisture in weak soil basic unit is upwards discharged by swelling gasbag, it is achieved soft soil foundation rapidly solidified；It is arranged on inside swelling gasbag on support bar and has several expansion links, these expansion links can give swelling gasbag mechanical support, preferably be strutted by swelling gasbag so that squeezing effect becomes apparent from；This utility model is recyclable repeatedly to be utilized, and it is the lowest to execute stressed cost, is effectively saved cost.
