Problems solved by technology

[0003] In recent years, foundation treatment engineering has gradually developed a combination of passive drainage and active drainage (vacuum, pump suction, etc.) to accelerate drainage and soil consolidation, but there are still the following problems: 1) Each well point is independent of each other, and a One well and one pump, the number of pumping equipment is large; 2) The precipitation of the foundation, especially in soft clay, the water output is not large, the recovery of the groundwater level is relatively slow, and the pumping needs to control the interval time, and special personnel must be equipped to control the flow and switch of the pumping equipment

Embodiment 1

[0024] Such as Figure 1-2 As shown, the foundation reinforcement automatic precipitation control device in the present embodiment includes:

[0025] a pumping device 7; and

[0026] The parallel pipeline connected with the pumping equipment 7 has a plurality of branch pipes 3 connected to the water collection chambers of the drainage consolidation structures 1 one by one.

[0027] Among them, the parallel pipeline is equipped with several valves whose flow rate can be monitored.

[0028] In this embodiment, the valve is an automatic control valve 5, which belongs to an electric control valve, and is connected to the electrical signal of the central control system; each automatic control valve 5 is equipped with a flow monitoring device 6, and the flow monitoring device 6 is connected to the electrical signal of the central control system. connection, the central control system judges whether to open or close the automatic control valve 5 of the relevant circuit according to...

Embodiment 2

[0039] The difference between the hardware configuration of Embodiment 2 and Embodiment 1 is: as image 3 As shown, each branch pipe 3 is equipped with an automatic control valve 5 . The same as in Embodiment 1 is: each automatic control valve 5 is equipped with a flow monitoring device 6 . By adopting the scheme of Embodiment 2, the flow rate of the drainage line of each drainage consolidation structure 1 can be monitored in real time, thereby controlling the automatic control valve 5 of the drainage line of each drainage consolidation structure 1 in real time, that is, , can control the on-off state of the drainage line of each drainage consolidation structure 1 in real time, which is equivalent to completely parallel control setting of the parallel pipelines.

[0040] Embodiment 2 is the same as steps S1, S2, and S6 of embodiment 1.

[0041] There are some differences between Embodiment 2 and the S3-S5 steps of Embodiment 1, the difference is:

[0042] S3. An automatic c...

Abstract

The invention discloses an automatic dewatering control method and device for foundation reinforcement. The method comprises the steps that a dewatering pipeline is set as parallel pipelines so as tocommunicate a plurality of drainage consolidation structural bodies, automatic control valves and flow monitoring equipment are arranged on the parallel pipelines, the automatic control valves and theflow monitoring equipment are connected with a central control system, and water level monitoring equipment is connected with the central control system; if it is judged that the flow monitoring indexes of the related lines in the parallel pipelines are larger than the flow control indexes, precipitation continues; if it is judged that the flow monitoring indexes of the related lines in the parallel pipelines are smaller than the flow control indexes, valves of the lines are closed, and the valves of the lines are opened after a period of time to continue precipitation; in the precipitation period, the central control system judges that the water level monitoring indexes in the drainage consolidation structure bodies are smaller than the water level control indexes through the water levelmonitoring equipment, and precipitation is finished; and if it is judged that the water level monitoring indexes in the drainage consolidation structure bodies are larger than the water level controlindexes, water pumping continues. According to the method, the cost is saved, and the precipitation benefit is maximized.

Description

technical field [0001] The invention relates to the technical field of foundation treatment, in particular to a foundation reinforcement automatic precipitation control method and device. Background technique [0002] In foundation treatment, the drainage consolidation method often sets vertical drainage bodies such as sand wells in the foundation, and then uses preloading to gradually discharge pore water in the soil, or constructs permeable piles in soft soil foundations Under the action of pile sinking, the pore water in the soil is gradually discharged along the drainage channel of the pile body. This kind of construction technology belongs to passive drainage in essence. [0003] In recent years, foundation treatment engineering has gradually developed a combination of passive drainage and active drainage (vacuum, pump suction, etc.) to accelerate drainage and soil consolidation, but there are still the following problems: 1) Each well point is independent of each other...
