At least a pair of connecting seats symmetrically is arranged at the bottom surface of a top baseplate and at least a shock transmission unit is arranged at one side of the top seat board.

The invention relates to the technical field of building materials. Aiming at the problems of uneven cement hydration and pores that cannot be eliminated in time in the existing mortar, it discloses a less-porous anti-cracking mortar and a preparation method thereof. The mixed mortar includes the following components: 650‑700 parts of furnace bottom slag, 220‑240 parts of granulated blast furnace slag powder, 48‑50 parts of titanium gypsum, 10‑12 parts of Portland cement clinker, 6‑8 parts of glass powder, 4‑6 parts of heavy calcium, 3-5 parts of modified water reducer, 1-3 parts of modified vermiculite, 0.3-0.5 parts of sodium dodecylbenzenesulfonate, 600-700 parts of water. The invention realizes the adjustment and modification of the added components, realizes the overall formula optimization of the mortar, eliminates the pore defects in the mortar forming process, prolongs the effective time of cement hydration, eliminates the internal thermal stress in time, and improves the size shrinkage and resistance of the model. Cracking ability.

The invention relates to an optical fiber end face processing method and an optical fiber connector. The method includes the steps of S1, penetrating an optical fiber through an insert core of the connector; S2, positioning length of one end, extending out of the insert core, of the optical fiber to form an extending end of the optical fiber; S3, inserting the extending end into a grinding groove of a grinder, using a grinding face of the grinding groove to abut the end face of the extending end to allow the end face to be in contact with the grinding face; S4, rotating the grinder, and grinding the end face of the extending end through the grinding face; wherein the length of the extending end is larger than the depth of the grinding groove. By the method, the problem of bad optical fiber end face cutting is solved, fully contact of optical fiber end faces is facilitated, return loss of the optical fiber connector is reduced, and insertion loss of the optical fiber connector is reduced.

The invention provides a positioning updating method and a mobile terminal. The position updating method comprises the steps that the mobile terminal makes sure that a cell attached to a first SIM card supporting 2G / 3G modes changes; the mobile terminals triggers a second SIM card supporting an LTE mode to carry out CS domain target cell searching; the mobile terminal sends the mark of the CS domain target cell searched for by the second SIM card to corresponding network equipment, so that when the network equipment makes sure that the CS domain target cell is different from a CS domain first cell, a position updating request is sent to the network equipment corresponding to the mark of the CS domain target cell, and then data of the mobile terminal are input into the network equipment corresponding to the mark of the target cell. According to the position updating method and the mobile terminal, the data of the terminal can be input into the network equipment corresponding to the target cell in time, when the mobile terminal carries out CSFB dropping, the mobile terminal can rapidly drop back to the cell where the terminal is located, and service connection capacity and the success rate are improved.

The present invention provides a method for redundant joint attachment, including: MME sends a message to the VLR corresponding to the 3G network, and the VLR stores MME information, and creates an association between the MSC of the 3G network and the SGs of the MME; and makes the HLR store the MSC position information of the 3G network ;Then the MME sends a location update request to the MSC of the 2G network, the VLR of the 2G network stores the MME information, and creates the relevant SGs association; and makes the HLR store the location information of the MSC of the 2G network; when there is an incoming call, if the MSC of the 3G network appears Failure, the HLR obtains the roaming number from the MSC of the 2G network to obtain the home location information of the mobile terminal, and the mobile terminal falls back to the 2G network cell to establish a call. The invention also includes a corresponding system. In the method and system of redundant joint attachment of the present invention, when the 4G multi-mode card has a voice service that needs to fall back, and the MSC of the 3G network is abnormal or the corresponding SGs interface fails, the call request is completed by the attached MSC of the 2G network , Improving the business connection ability and success rate.
