Problems solved by technology

[0004] However, in actual use, after the depth-measuring drainage component is inserted into the ground, the sounding line will be affected by the geomagnetic field, so that a potential difference will be generated between the two wires (when the depth-measuring drainage component is not inserted underground, there will be no This potential difference), this potential difference will affect the accuracy of the measurement results of the capacitance value alone, or will affect the accuracy of the measurement results of the capacitance value after being superimposed with the measurement voltage applied between the two strands of wires, which makes it difficult to grasp the insertion of the drainage component into the ground. actual depth

Embodiment 1

[0021] Such as figure 1 , 2 As shown in the depth-measuring drainage plate component with a shielding layer, the core plate 1 is made of plastic plate or synthetic resin net, and several longitudinal drainage channels are opened on both sides, and the core plate is wrapped with a filter membrane layer 2, which can be made of Non-woven fabric is sewn or bonded with chemical glue. In the seam of the filter membrane layer 2, two enameled wires (depth-sounding wires) 3, 4, which are regularly intertwined, are longitudinally placed. The enameled wire is evenly wound on the longitudinal axis. The two enameled wires 3 and 4 are covered with a layer of aluminum-plastic composite tape 5, which constitutes a magnetic field shielding layer.

Embodiment 2

[0023] Such as image 3 As shown in the depth-measuring drainage plate component with a shielding layer, two strands of enameled wires 3 and 4 are regularly intertwined, and a layer of shielding paint 6 is coated on the outside of the enameled wires and placed in the drainage channel of the core plate 1 corresponding to the bonding place of the filter membrane layer. , other structures are the same as those in Embodiment 1.

Embodiment 3

[0025] Such as Figure 4 , 5 As shown in the depth-measuring drainage board member with a shielding layer, the shielding sleeve 7 is covered outside the two parallel parallel metal wires 3 and 4, and the isolation sleeve 7 is arranged outside the filter membrane layer 2 (not limited to the bonding place shown in the figure) , can be any suitable position on the outer surface of the filter membrane layer), and other structures are the same as in Embodiment 1.

[0026] The mutual setting method and setting position of the two strands of sounding lines involved in the present invention, and the structure of the shielding layer can be freely combined according to the actual situation according to the schematic diagram of the above-mentioned embodiments (for example, the spacer sleeve covering the parallel parallel metal wires is arranged on the The bonding place of the non-woven filter membrane layer) to achieve the use effect according to local conditions.

Abstract

A depth-measuring drainage component is provided for the shielding layer, and the drainage component is used for drainage of soft ground with high water content, and it is convenient to detect the depth of its insertion into the ground through instruments. There are defects in the prior art that it is inconvenient to accurately measure the insertion depth into the ground and difficult to operate. The present invention includes a core plate with a longitudinal drainage channel and a filter membrane layer wrapped outside the core plate, and is characterized in that a sounding element is arranged longitudinally in the drainage member, and the sounding element includes at least two strands whose relative positions are determined The sounding lines are insulated from each other, and the sounding element is covered with a magnetic field shielding layer. Guaranteed measurement accuracy, easy to use, easy to operate, suitable for harsh working conditions on construction sites.

Description

【Technical field】 [0001] The invention relates to a depth-measuring drainage component provided with a shielding layer. The drainage component is used for drainage of soft soil foundations with high water content, and is convenient for detecting the depth inserted into the ground by instruments. 【Background technique】 [0002] Existing drainage components generally include a core plate made of plastic or synthetic resin mesh and a filter membrane layer wrapped outside the core plate (usually bonded or sewn with non-woven fabrics), and the core plate has longitudinal drainage on both sides. aisle. When dealing with soft soil foundations with high water content, the drainage components are inserted into the ground, and then pressure is applied to the foundation to make the groundwater flow to the surface through the drainage channel to be discharged. In order to facilitate the measurement of the depth of the drainage board inserted into the ground, effectively control the con...
