Abstract
The utility model relates to a sealing performance of a sealing film discharge system, in particular to a vacuum apparatus film discharge system in the large-area combined vacuum and surcharge preloading treatment. According to a self-sealing device for a film discharge pipe of a vacuum system in the combined vacuum and surcharge preloading treatment, the vacuum system comprises a thin film and the film discharge pipe for monitoring the vacuum degree, in which the thin film is inserted; the self-sealing device comprises two soft and horn-shaped self-sealing parts; and the self-sealing parts are sequentially sleeved on the film discharge pipe. The self-sealing device is used for carrying out automatic sealing and the self-sealing performance of the sealing film system is strengthened.
Description
Technical field
The utility model relates to diaphragm seal membrane system, relates in particular to vacuum plant membrane system in the large-area vacuum combined stack-load precompressed processing.
Background technology
For active response and promote economy type society; Vacuum combined stack (surpassing) carries precompressed advantages such as relatively low and difficulty of construction is less as the punishment expense and in soft foundation punishment construction, is widely used; But the construction of vacuum piling prepressing is long in time limit than other punishment method, is the emphasis of vacuum piling prepressing construction so guarantee the construction period.Yet in work progress, occur diaphragm seal gas leakage often and cause vacuum pressure dynamics deficiency and the duration that lags behind, sealing system self sealss performance is the difficult point that engineers and technicians capture always.
Summary of the invention
The utility model is intended to address the above problem, and a kind of vacuum system membrane pipe self-seal device of vacuum combined stack precompressed is provided.The utility model seals voluntarily, enhanced leaktightness film system from close property.
For addressing the above problem; A kind of vacuum system membrane pipe self-seal device of vacuum combined stack precompressed; Said vacuum system comprises film and the membrane pipe that penetrates film that is used for monitoring vacuum; Said self-seal device comprise two soft, flaring from confidential paper, they are sleeved on the said membrane pipe successively.
The vacuum system membrane pipe self-seal device of described vacuum combined stack precompressed, two in confidential paper, the vacuum diaphragm in the centre is adsorbed between confidential paper through vacuum system.
The utility model material is soft and firmly be not destroyed with the protection diaphragm seal, and certain adhesion stress is arranged simultaneously, make diaphragm seal be connected from confidential paper closely knit air tight.Be made according to drainage system caliber size from confidential paper, from confidential paper certain-length environmental sealing film must be arranged, strengthen the self seal degree, and receive diaphragm seal top follow-up preloading soil construction infection, it is suitable to take all factors into consideration from confidential paper length 5-10cm.In confidential paper, the enhanced leaktightness film is from close performance with diaphragm seal opening portion secure lock for the utility model, forms more tight from close system.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model sketch map.
The specific embodiment
As shown in Figure 1; A kind of vacuum system membrane pipe self-seal device of combined vacuum and surcharge preloading; Said vacuum system comprises film and the membrane pipe 2 that penetrates film that is used for monitoring vacuum;, said self-seal device comprise two soft, flaring from confidential paper 1, they are sleeved on the said membrane pipe 2 successively.Two in confidential paper, the vacuum diaphragm 3 in the centre is adsorbed between confidential paper.
Claims (2)
1. the vacuum system membrane pipe self-seal device of a vacuum combined stack precompressed; Said vacuum system comprises film and the membrane pipe that penetrates film that is used for monitoring vacuum; It is characterized in that; Said self-seal device comprise two soft, flaring from confidential paper, they are sleeved on the said membrane pipe successively.
2. the vacuum system membrane pipe self-seal device of vacuum combined stack precompressed according to claim 1 is characterized in that, two in confidential paper, the vacuum diaphragm in the centre is adsorbed between confidential paper through vacuum system.
