Description
Technical field
The present invention relates to geotechnical grid technical field of structures, and in particular to the fixed Integral geocell of pipe nail.
Background technology
The purposes of geotechnical grid：1, for consolidating highway subgrade：High resiliency power and firm roadbed can be generated, and it is traditional
Compared to that can reduce 50% or more base thickness, the pressure lateral dispersion contacted gravity and with ground is simultaneously reduced, and can on stone basis
For temporary or permanent road construction.2, for consolidating railway bed：Rubble and grading transverse shifting can be prevented,
Keep entirety firmer, prevent from drawing water, collapses prevented also from entire or part even if ground is soft.In the big area of the volume of traffic as handed over
Road, branch road and slalom course are pitched, service life can be dramatically increased.3, dyke, the barricade for bearing carrying force：It is broken to define reinforcing
The cubic meter of stone forms consistent structure, can stop transverse pressure, no matter stratum is slided and agglomerated, all can voluntarily adjust, can support non-
Structural plane and naturally plant generating layer, can vertical or stepped design.4, shallow water river channel is used to administer：Three face solid grids reinforce embankment
Strength, prevent erosion and increase carrying force, it is possible to reduce the construction cost in shallow river simultaneously allowed the design in river to accord with
Close traffic and the various conditions of soil property.5, pipeline and sewer are used to support：It digging and can need not be placed a large amount of using geotechnical grid
Support construction of the stone as pipe bed type sewer form a firm durable overall plate structure using conventional material, it is right
Pipeline provides flexible permanent protection, can reduce due to micro sinking caused by long-time, keeps the basis of pipeline harder
Gu and local collapse can be prevented for a long time.This method easy construction is reduced and is excavated, long range bulk transport pipeline is more passed through
Ji is practical.6, for preventing landslide and by the hybrid barricade of carrying force：Template need not be used, you can create one layer of firm wall
Face is firmly combined into one with backfill side, though traditional various gravity structures can not use situation embankment if can be on the spot
Materials significantly reduce engineering cost.7, independent wall, harbour, flood bank etc. are used for：Promptly independent wall or obstacle wall can be played by structure,
And permeable granular embankment dyke or weir wall can be used, if temporary facility needs to remove, geotechnical grid is also recyclable.In code
Head or flood bank and other important seashore purposes are also very extensive.When 8, encountering subgrade in highway, use
Sandstone replaces the method for Soft Soil Layer, and investment is big, long in time limit.Construction labor intensity can be mitigated using geotechnical grid significantly, reduce road
Base thickness, speed of application is fast, and performance is good, substantially reduces project cost.Next builds the road simple for process, can gather materials on the spot, soon
Fast efficient, this point is particularly important in the deficient area of road-making material.
Geotechnical grid is usually connected by the band body of a plurality of PP or PE materials by different modes, to form netted cell compartment knot
Structure, existing connection type include welding, riveting, and welding is so that two band bodies is bonded together by high temperature, and this mode is viscous
The tensile strength for meeting place is low, is easy to be broken in junction, and to influence the stability of entire geotechnical grid structure, riveting is
Directly two band bodies are fixed together with rivet, this makes band body drilled and impaired, influences the service life of product.
Invention content
It is an object of the invention to overcome the above-mentioned problems in the prior art, a kind of fixed peace of geotechnical grid is provided
Assembling device, adjacent band body can be securely attached to together by it, and tensile strength is high, to band body fanout free region itself, be improved
The stability and service life of geotechnical grid integral product.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved by the following technical solutions：
A kind of fixed Integral geocell of pipe nail, includes the band body of several geotechnical grids being placed adjacent, further includes
The connector that adjacent belts body is fixedly connected, the connector are formed by fixing metal tube, capping and bottom cover；
The fixed metal tube is the round tube shape structure of both ends perforation, and six are offered on the side wall of the fixed metal tube
What is be radially arranged connects seam, and the seam equidistantly distributed that connects is described to connect seam bottom lock on the side wall of fixed metal tube
And the top of fixed metal tube is run through at top；
The fixed metal tube top outer wall is equipped with the first external screw thread, is equipped on the inside of the capping and matches with the first external screw thread
The first internal thread closed；
The fixed metal tube bottom end outer wall is equipped with the second external screw thread, is equipped on the inside of the bottom cover and matches with the second external screw thread
The second internal thread closed, the bottom cover bottom are equipped with socket joint needle vertically；
Two band bodies connect seam from one jointly and penetrate fixed metal tube, then two-way is divided to gradually to connect seam from another two
It is pierced by, penetrates fixed metal tube, finally connecting seam from the last item jointly is pierced by fixed metal tube.
Further, the bottom cover is equipped with and the matched reinforcing rib of socket joint needle.
Further, the socket joint wire surface is equipped with corrosion-resistant coating.
Further, the socket joint needle is an integral structure with bottom cover.
Beneficial effects of the present invention are：
1. gradually interting with body for geotechnical grid is connected seam into being arranged on fixed metal tube so that fixed effect is more
It is good, improve the intensity with body resisting longitudinal pulling force and lateral pull；
2. setting capping makes band body not skid off fixed metal tube；
3. socket joint needle is designed to that integral structure is connected through a screw thread with fixed metal tube with bottom cover, it is laid with geotechnique at the scene
When cell compartment, can socket joint needle be directly inserted into ground, be not necessarily to traditional limit ground nail accessory, it is more convenient to use；
4. band body, fixed metal tube, capping and bottom cover are detachable connection, installation is lossless to its ontology when connecting
It is bad, it is more convenient to recycle and recycle.
