Problems solved by technology

However, the construction method of wooden wedge fixing is not reliable, and the joint box may be separated from the rubber waterstop during the lifting and sinking process due to the loose fit, which will affect the construction process and construction quality
Moreover, the efficiency of manual installation of wooden wedges is low, which affects the construction progress, and the quality of the work is closely related to the technical proficiency of the workers. Improper operation may also cause damage to the rubber waterstop joints.

Embodiment 1

[0030] Please refer to Figures 1 to 5 , the first embodiment provides a magnetic suction waterstop joint, including a waterstop 200 and a joint box 100 made of magnetically conductive materials such as electrical pure iron or steel, and the waterstop 200 is inserted and connected to the joint box 100 In the bite 101 of the mouth, it also includes an electromagnetic fixing device for fixing the waterstop 200 and the joint box 100; the electromagnetic fixing device includes a plurality of uniformly distributed electromagnets 102, and each of the electromagnets 102 is magnetically For example, a magnetically conductive plate 213 made of a steel plate is connected, each of the electromagnets 102 is fixedly connected to the inner surface of the box body of the bite 101 of the connector box 100, and each of the electromagnets 102 is electrically connected to a switch through a wire 103 The controller 104 , the switch controller 104 is electrically connected to the power source 110 ...

Embodiment 2

[0039] The second embodiment provides a construction method for the magnetic waterstop joint of the first embodiment, which includes the following steps:

[0040] Step 1, disconnect all the electromagnets 102 of the electromagnetic fixing device from the power supply 110 through the switch controller 104, so that the electromagnets 102 are de-energized and no magnetic attraction force is generated;

[0041] Step 2: Hoist the joint box 100 with a crane, position it above the end of the excavated underground diaphragm wall’s front construction groove section, insert and fix the fixing unit 230 of the waterstop 200 into the bite of the joint box 100 within 101;

[0042] Step 3: Slowly lower the joint box 100 into the front construction groove section, and at the same time insert the rubber water-proof connecting belt unit 220 and the rubber water-stop belt unit 210 of the waterstop 200 into the bite of the sinking joint box 100 101, when the rubber waterstop unit 210 at the lowe...

Abstract

The invention discloses a magnetic type water-stop belt connector and a construction method thereof. The magnetic type water-stop belt connector comprises a water-stop belt (200) and a connector box (100) made of magnetic conductive materials, and the water-stop belt (200) is inserted into a seam (101) of the connector box (100). The magnetic type water-stop belt connector further comprises an electromagnetic fixing device which is composed of a plurality of uniformly-distributed electromagnets (102) and magnetic conductive plates (213) which are magnetically connected with all the electromagnets (102). Each electromagnet (102) is fixedly connected to the inner side face of a box body of the seam (101) of the connector box (100), all the electromagnets (102) are electrically connected with an on-off controller (104) through wires (103), and the on-off controller (104) is electrically connected with a power source (110). The magnetic conductive plates (213) are fixedly connected to the water-stop belt (200). According to the magnetic type water-stop belt connector and the construction method thereof, the water-stop belt and the connector box can be reliably and fixedly connected in the construction process.

Description

technical field [0001] The invention relates to the technical field of foundation construction, in particular to a magnetic suction waterstop joint and a construction method thereof. Background technique [0002] At present, in the foundation construction of industrial and civil construction projects, the underground diaphragm wall is a widely used method because it can give full play to the bearing capacity of the soil layer, and has the advantages of large rigidity, small deformation, high bearing capacity, and suitable for mechanized construction. The base type to use. Among them, the joint waterproofing of the underground diaphragm wall is the focus of the construction quality control of the underground diaphragm wall. In the construction process of the underground diaphragm wall, the underground diaphragm wall is actually spliced ​​by one groove segment after another, so the waterproof between the groove segments becomes very important. The rubber waterstop joint has ...
