Abstract
The invention discloses a vacuum preloading treatment system. The vacuum preloading treatment system comprises a sealing system for covering soil; a drainage plate is arranged in the soil, and is connected with an external vacuumizing device through a pipe; a sand pile is piled in the insertion place of the soil above the drainage plate around the pipe; and the pipe is sleeved with a circular protecting disc. In a vacuum preloading treatment system with a traditional structure, a connecting head of the drainage plate is liable to puncture a sealing film and geotechnical cloth in vacuum preloading to cause leakage of a sealing system, so that the vacuum preloading effect is largely reduced. The vacuum preloading treatment system is provided with the sand pile and sleeved with the circular protecting disc for preventing excessive sinking of the sealing film and the geotechnical film to prevent puncture by the connecting head of the drainage plate.
Description
Technical field
The present invention relates to a kind of vacuum preloading processing system.
Background technology
In the vacuum preloading processing system of traditional structure, there is connector to be connected with pipeline for drain bar upper end, carry out vacuum
During precompressed, at drain bar the soil body because pump drainage cause the soil body sink, cause the sharp parts of the connector of drain bar protruding upward, and
Diaphragm seal and geotextiles in sealing system can also be covered downwards after evacuation, it is easy to cause the connector of drain bar to puncture
Diaphragm seal and geotextiles, cause sealing system leakage occur, and the effect for processing vacuum preloading is substantially reduced.
The content of the invention
In order to overcome the deficiencies in the prior art, the technical problems to be solved by the invention to be to provide one kind and can avoid sealing
The vacuum preloading processing system that film and geotextiles are excessively sunk and are punctured.
The technical solution adopted for the present invention to solve the technical problems is：Vacuum preloading processing system, including it is covered in soil
Sealing system on body, has set drain bar in the soil body, drain bar is connected by pipeline with the vacuum extractor of outside, its feature
It is：There is sand drift the insert division of the drain bar top soil body around the conduit stack, and circular protection disk is cased with the pipeline.
Technique effect of the invention：1st, sand drift can fill sagging position when the soil body at drain bar sink, to top
Diaphragm seal and geotextiles play supporting role, it is to avoid it is punctured；2nd, the circular protection disk being socketed on pipeline can be covered
Drain bar connector, prevents it from puncturing diaphragm seal and geotextiles, and especially the soil body sink, and degree is larger to cause the landfill nothing of sand drift
When method covers drain bar connector.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
The structural representation of the vacuum preloading processing system of Fig. 1 present invention the first embodiment offers.
The structural representation of sand drift, circular protection disk and supporting chassis that Fig. 2 is provided for second embodiment of the invention.
Fig. 3 is the schematic top plan view of Fig. 1.
The structural representation of sand drift, circular protection disk and supporting chassis that Fig. 4 is provided for the third embodiment of the invention.
Specific embodiment
Shown in reference picture 1, the vacuum preloading processing system that the first embodiment of the invention is provided, including be covered on the soil body
Sealing system, has set drain bar 1 in the soil body, drain bar 1 is connected by pipeline 2 with the vacuum extractor 3 of outside, the draining
There is sand drift 4 insert division of the top soil body of plate 1 around the heap of the pipeline 2, and circular protection disk 5, circle protection are cased with the pipeline 2
Disk 5 is covered on sand drift 4.
Shown in reference picture 2, Fig. 3, second embodiment of the invention is essentially identical with the first embodiment, and its difference only exists
In：On the basis of above-described embodiment one in order to avoid the soil body sink scope it is larger when sand drift be not enough to landfill downset areas and
Circle protection disk also excessively sink therewith, and circular protection disk 5 bottom is provided with supporting chassis 6, and the supporting center of chassis 6 carries
Pipeline jack 7 and at least three support feets 8 with cross direction profiles, the covering model of the protruding circular protection disk 5 of support feet 8
Enclose.When downset areas are larger, the length that support feet 8 is extended laterally out is larger, it is sufficient to be erected at the periphery of downset areas, no
Circular protection disk 5 can be caused excessively to sink therewith, it is to avoid diaphragm seal and geotextiles 9 are excessively involved, and then cause breakage, influence
Sealing effectiveness.
Shown in reference picture 4, the third embodiment of the invention is essentially identical with second embodiment, and it is differed only in：Institute
State circular protection disk 5 bottom and be provided with supporting chassis 6, the center of supporting chassis 6 carries pipeline jack 7, under the supporting chassis 6
Portion carries at least three inserted links 10, has been arranged in pairs around the pipeline jack 7 on the circular protection disk 5 and supporting chassis 6
At least three pairs upper bushes 11 and lower sleeve 12, upper bush 11 are mutually socketed with lower sleeve 12, are set in upper bush 11 and lower sleeve 12
It is equipped with back-moving spring 13.The inserted link 10 on the supporting chassis 6 can be previously inserted in the soil body, by upper bush 11, lower sleeve 12 and multiple
Geomembrane and packing cloth 9 can be propped up certain altitude by the circular protection disk 5 that position spring 13 has been supported, and the pipeline 2 to lower section is reserved
Certain space, when evacuated, diaphragm seal and geotextiles 9 are pressed downward circular protection disk 5 under vacuum pressure effect, and circle is protected
Protection plate 5 can overcome the effect of back-moving spring 13 to move down, this structure not only can vacuum preloading start front support diaphragm seal and
Geotextiles 9, return diaphragm seal and geotextiles 9 reserve certain downlink spatial, and diaphragm seal and geotextiles 9 can be supported
Protection, it is to avoid involved because the soil body excessively sink or puncture diaphragm seal and geotextiles 9.
