Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a groundwater level control device and construction method for high-water-level silty geological conditions. Background Technology

[0002] Groundwater level refers to the elevation of the groundwater surface relative to a reference level, usually calculated as absolute elevation; the elevation of the unconfined water surface is called the "unconfined water level"; the elevation of the confined water surface is called the "confined water level". Based on drilling and observation time, it can be categorized into initial water level, stable water level, high-water season water level, low-water season water level, and pre-freezing water level, etc.

[0003] During construction, to prevent groundwater infiltration from affecting the concrete pouring of underground piles, it is necessary to promptly extract the infiltrating groundwater at the construction site and ensure that the water level at that location is below a certain value. However, in silty geological environments, it is difficult to monitor the actual groundwater level. Therefore, this invention proposes a groundwater level control device and construction method for high-water-level silty geological environments to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a groundwater level control device and construction method for high-water-level silty geological conditions, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a groundwater level control device for high-water-level silty geological conditions, the high-water-level silty geological groundwater level control device comprising:

[0006] An outer protective shell, which is a cylindrical structure, has an external through hole, and an outer filter membrane is fixedly installed in the external through hole;

[0007] The upper cover is fixedly installed on the upper end of the outer protective shell;

[0008] A pressure detection seat is composed of a primary partition layer, a secondary partition layer, a tertiary partition layer, an upper sealing plate, and a lower sealing plate. The primary partition layer, the secondary partition layer, the tertiary partition layer, and the outer protective shell are coaxially arranged. The upper and lower ends of the primary partition layer, the secondary partition layer, and the tertiary partition layer are respectively connected to the upper sealing plate and the lower sealing plate. A liquid storage cavity is formed between the primary partition layer and the secondary partition layer, and a conductive cavity is formed between the secondary partition layer and the tertiary partition layer. A primary through hole is opened on the secondary partition layer, and a secondary through hole is opened on the tertiary partition layer. An installation tube is installed between the primary through hole and the secondary through hole. A diaphragm is fixedly installed on the inner side of the inner cavity of the installation tube. A connecting groove is opened on the lower end face of the secondary partition layer, and the liquid storage cavity and the conductive cavity are connected through the connecting groove.

[0009] The inner conductive sheet has a primary embedding groove on the outer wall of the secondary separator layer, and the inner conductive sheet is embedded in the primary embedding groove.

[0010] The outer conductive sheet has a two-stage embedding groove on the inner sidewall of the three-stage separation layer, and the outer conductive sheet is embedded in the two-stage embedding groove.

[0011] The upper ends of the inner and outer conductive sheets are respectively connected to a primary conductor and a secondary conductor, both of which are electrically connected to the ammeter. Conductive liquid is injected into the storage chamber and the conductive chamber.

[0012] Preferably, both the inner and outer conductive sheets are annular tubular structures, and the inner and outer conductive sheets are respectively provided with three-level and four-level through holes. The three-level, four-level, one-level, and two-level through holes are correspondingly arranged, and the mounting tube passes through the three-level, four-level, one-level, and two-level through holes. The contact points between the mounting tube and the edges of the holes of the one-level and two-level through holes are sealed with sealant.

[0013] Preferably, the primary and secondary conductors pass through the wiring grooves on the upper sealing plate and the upper cover, and the primary and secondary conductors are sealed to the sidewalls of the wiring grooves with sealant.

[0014] Preferably, the conductive liquid is a saturated sodium chloride solution, and the amount of conductive liquid injected is half the total volume of the storage chamber and the conductive chamber.

[0015] Preferably, the diaphragm is an elastic silicone membrane, and when the diaphragm is in the reset state, it is hemispherical.

[0016] Preferably, an inner filter membrane is fixedly installed at the outer port of the mounting tube, wherein the outer filter membrane is a microfiltration membrane and the inner filter membrane is an ultrafiltration membrane.

[0017] Preferably, the outer side of the mounting tube protrudes from the outer side of the three-level separation layer, and a guide groove is provided on the inner side wall of the outer protective shell. The width of the guide groove matches the outer diameter of the mounting tube. When the pressure detection seat is installed in the inner cavity of the outer protective shell, its mounting tube is correspondingly set with the outer through hole, and the inner diameter of the mounting tube matches the diameter of the outer through hole.

[0018] Preferably, a sealing gasket is fixedly glued to the end of the mounting tube, and during actual installation, the end face of the sealing gasket of the pressure detection seat is set to abut against the bottom of the guide groove.

[0019] Preferably, the primary partition layer has an installation groove, in which a reset component is installed. The installation groove is composed of a primary groove, a secondary groove, and a tertiary groove, arranged in a stepped manner. The reset component is composed of a guide rod, a reset spring, and a top. The top is hemispherical and integrally formed with the guide rod. The reset spring is sleeved on the guide rod, and the guide rod is movably disposed in the tertiary groove. The reset spring is disposed in the secondary groove, and the diameter of the top matches the diameter of the primary groove.

[0020] A construction method for a groundwater level control device in high-water-level silty geological conditions includes the following steps:

[0021] Step 1: The installation process of the water level control device involves positioning the water level control device below the soil layer;

[0022] Step 2: The water filtration process. The water in the sludge permeates into the installation pipe through the outer and inner filter membranes, creating hydraulic pressure. This pushes the diaphragm inward, squeezing the conductive liquid in the storage chamber. This causes some of the conductive liquid to flow into the conductive chamber through the connecting groove, raising the liquid level in the conductive chamber. This increases the effective conductive area between the inner and outer conductive plates, causing a change in the current of the ammeter.

[0023] Step 3: Groundwater extraction process. When the groundwater pressure in the silty geological area is too high, the sludge is extracted using a sludge pump to control the groundwater level in the silty geological area.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. A groundwater level control device for high-water-level silty geological formations is constructed by setting up an outer protective shell, a top cover, a pressure detection seat, an inner conductive sheet, and an outer conductive sheet. Conductive liquid is injected into the storage chamber and conductive chamber on the pressure detection seat. The pressure of the groundwater causes a change in the liquid level in the conductive chamber, which in turn causes a change in the effective conductive area between the inner and outer conductive sheets, thereby causing a change in the current of the ammeter, so as to achieve the purpose of monitoring the pressure of the groundwater.

[0026] 2. By opening guide grooves on the inner wall of the outer protective shell and ensuring that the width of the guide grooves matches the outer diameter of the installation pipe, it is easy to align the installation pipe with the outer through hole. This allows for secondary filtration while effectively controlling the flow area, thus facilitating the overall maintenance and cleaning of the device.

[0027] 3. By opening an installation groove on the primary partition layer and installing a reset assembly consisting of a guide rod, a reset spring, and a top head in the installation groove, the reset assembly can push the diaphragm outward, thereby resetting the liquid level in the conductive cavity.
