Example Embodiment

[0029] Example one

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

Example Embodiment

[0038] Example two

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

[0040] Step 1: Disconnect all 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 is generated;

[0041] Step 2: Lift the joint box 100 with a crane, position it above the end of the front construction trough section of the excavated diaphragm wall, insert and fix the fixing unit 230 of the waterstop 200 to the bite of the joint box 100 Within 101;

[0042] Step three, slowly lower the joint box 100 into the front construction tank section, and at the same time insert the rubber water-stop connection belt unit 220 and the rubber water-stop unit 210 of the waterstop 200 into the bite of the sinking joint box 100 slowly In 101, when the rubber waterstop unit 210 at the bottom end ...

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 ...
