Embodiment 1

[0042] Embodiment one sees figure 1 , figure 2 As shown, this ultra-large area, high-efficiency and energy-saving vacuuming soft foundation treatment system consists of four parts: vacuuming device, gas-liquid separation device, water collection device and vacuum data automatic transmission device. The vacuuming device is connected with the gas-liquid separation device. The gas-liquid separation device is in communication with the water collection device.

[0043] The vacuum data automatic transmission device is composed of a vacuum data signal sensor 24, a vacuum data automatic transmitter 25 and a vacuum data receiver 26. The vacuum data signal sensor 24 and the vacuum data automatic transmitter 25 are all buried under the sealing film 19. In the sand cushion layer 20.

[0044] The vacuum data signal sensor 24 is made up of a pressure sensing module and a pressure data acquisition module, wherein the pressure sensing module measures the vacuum data (i.e. vacuum degree) in...

Embodiment 2

[0051] Embodiment two see image 3 , Figure 4 , the difference from the first embodiment is that the gas-liquid transmission branch pipe 11 in the second embodiment is also provided with a control valve 10 . At the same time, the water storage tank 1 is arranged above the sealing film 19 , and the catchment device passes through the sealing film 19 from top to bottom and is buried in the sand cushion 20 .

[0052] Applying the construction method of the super-large-area high-efficiency energy-saving vacuuming soft ground treatment system, the construction steps are as follows:

[0053] Step 1. Lay woven cloth, brambles and non-woven geotextiles on the foundation to be treated.

[0054] Step 2: Laying medium-coarse sand to form a sand cushion 20. For areas that cannot meet the construction requirements of medium-coarse sand for filling, take reinforcement measures such as laying geotextiles and brambles.

[0055] Step 3, setting up the vertical drainage board 22 and the hor...

Abstract

The invention provides an oversized-area efficient energy-saving vacuumizing soft foundation treatment system and a construction method. The system is composed of a vacuumizing device, a gas-liquid separation device, a water collection device and an automatic vacuum data transmission device. The automatic vacuum data transmission device is composed of a vacuum data signal sensor, an automatic vacuum data transmitter and a vacuum data receiver. The vacuum data signal sensor is composed of a pressure induction module and a pressure data collection module. The vacuum data receiver is composed of a wireless signal receiving module and a display module. According to the system, the mode that data are monitored by a worker everyday is changed into the mode that data are automatically transmitted and monitored and technicalization and automation of the construction technique and management are facilitated; the structure that a jet pump and a water storage tank are designed in a split mode is adopted in the gas-liquid separation device, so that the system is transported, repaired and replaced in a soft foundation conveniently, and the defect that the traditional vacuum preloading technology is large in power consumption is overcome by the system.

Description

technical field [0001] The invention relates to a vacuum system used in the technology of vacuum preloading to strengthen soft soil foundations, and a construction method for using the vacuum system to treat soft soil foundations. Background technique [0002] Soft soil is the general term for silt and silty soil. It is mainly composed of silt deposits with high natural water content, high compressibility, low bearing capacity and a small amount of humus. It has high natural water content, large natural void ratio, It has the characteristics of high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor water permeability, complex layered distribution of soil layers, and large differences in physical and mechanical properties between layers. Soft soil is generally in the state of soft plastic or flow plastic. Once its structure is disturbed and destroyed, its strength will be drastically reduce...
