Embodiment 1

[0033] Floating anchors need to be tested for their pressure before use. The existing anti-floating anchors are usually composed of three reinforcing bars. see Figure 1-6 , and discloses an anti-floating anchor rod detection device and a detection method for underground space, wherein the anti-floating anchor rod detection device for underground space includes a lower end connecting seat 2 and a floating rod main body 1 at the lower end of the lower end connecting seat 2, and the lower end connecting seat 2. The upper end is provided with a fixed shaft 3, the top of the fixed shaft 3 is provided with a fixed inner notch 4, the upper end of the fixed shaft 3 is installed with a matching shaft sleeve 8, the interior of the matching shaft sleeve 8 is provided with a through groove 27, and the upper end of the matching shaft sleeve 8 is provided. A hydraulic cylinder 9 is installed, a hydraulic pressure chamber 19 is arranged inside the hydraulic cylinder 9, a driving inner shaft...

Embodiment 2

[0036] The pulling of the product by the detection device will lead to insufficient supporting strength, and a supporting structure is required. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-6 , a fixed seat 5 is installed on the upper end of the fixed shaft 3 .

[0037] Place the fixing base 5 on the upper end of the ground, and pass the fixing shaft 3 through the through groove 27 of the fixing base 5. At this time, one end of the fixing bolt 11 can be inserted from the upper end of the fixing base 5, and the fixing bolt 11 can be screwed into the thread. and the upper end diameter of the fixing bolt 11 is larger than the inner diameter of the through groove 27, so that the pressure of the fixing bolt acts on the inner side of the fixing seat 5, and forms a fixing effect on the fixing shaft 3, and improves the supporting effect between the fixing shaft 3 and the ground.

Embodiment 3

[0039] The structural strength of the fixed seat 5 is not enough, and it is difficult to support a large weight. This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-6 The outer side of the fixed seat 5 is provided with a reinforcing rib plate 6 , and the lower end of the reinforcing rib plate 6 is provided with a fitting base 7 .

[0040] When the floating rod main body 1 exerts the pressure on the outside of the fixed seat 5 through the fixing bolt 11 , the fixed seat 5 will disperse the pressure at the reinforcing rib plate 6 and press down on the fitting base 7 through the downward pressing of the reinforcing rib plate 6 force, and the fitting base 7 is perpendicular to the reinforcing rib plate 6, and is completely in contact with the ground, effectively dispersing the force of the reinforcing rib plate 6 pressing down, expanding the bearing area of ​​the fitting base 7, thereby improving, The supporting area of ​​the...

Abstract

The invention relates to the technical field of anti-floating anchor rods, and discloses an anti-floating anchor rod detection device for underground space and a detection method.The anti-floating anchor rod detection device for the underground space comprises a lower end connecting base and a floating rod body at the lower end of the lower end connecting base, and a fixing shaft is arranged at the upper end of the lower end connecting base; a fixing inner notch is formed in the top end of the fixing shaft, a matching shaft sleeve is installed at the upper end of the fixing shaft, a penetrating groove is formed in the matching shaft sleeve, a hydraulic cylinder body is installed at the upper end of the matching shaft sleeve, a hydraulic pressure cavity is formed in the hydraulic cylinder body, and a driving inner shaft is installed in the hydraulic cylinder body. A piston is installed on the outer side of the driving inner shaft, and a pressure sensor is installed at the lower end of the driving inner shaft. According to the device, a hydraulic pressure detection mode is adopted, the manual operation intensity is greatly reduced, operation is easy, use is convenient, and the hydraulic cylinder body and the fixing shaft can be fixed only through an outer hexagon wrench.

Description

technical field [0001] The invention relates to the technical field of anti-floating anchor rods, in particular to an anti-floating anchor rod detection device and a detection method for underground spaces. Background technique [0002] Anti-floating anchor is one of the anti-floating measures for underground structures of construction projects. The anti-floating anchor refers to the structural member set up to resist the upward displacement of the building above it. It is related to the groundwater level and changes, and is opposite to the stress direction of the compressive pile, and this device is used for the anti-floating anchor. pressure test structure. [0003] However, the existing anti-floating anchor rod needs to be tested for its pressure before it is used, and the existing anti-floating anchor rod is usually composed of three reinforcing ribs. When the detection structure is connected with it, the operation is extremely inconvenient. It is difficult to install ...
