Embodiment 1

[0058] Such as figure 1 As shown, a connector for a sand-fixing board includes a positioning board 1 solidified by magnesium cement mortar 6 and a rib 2 with one end solidified on the inner bottom of the positioning board, wherein the top of the positioning board 1 is formed with a Groove 3 where the sand-fixing board is inserted.

[0059] When in use, insert the sand-fixing plate 4 into the groove 3 to realize the fixed connection between the connector and the sand-fixing plate, and after the connection, the positioning plate 1 and the sand-fixing plate cross vertically.

[0060] The ribs are preferably arranged perpendicular to the bottom edge of the positioning plate to improve the wind resistance of the connector. At the same time, the ribs can also have a certain angle with the bottom edge. The number of ribs on each connector is preferably but not limited to 2-5 One, the ribs are plant fibers, thin metal rods or magnesium bars. The plant fibers can be but not limited t...

Embodiment 2

[0088] The mold 5 structure of preparing described connector is as follows:

[0089] Described mold comprises detachably connected half mold frame 51 and perforated template 52, and described half mold frame 51 and perforated template 52 encircle and form mold frame, and mold cavity 53 is formed in the described mold frame, and described mold cavity The shape and size are the same as the shape and size of the connecting piece of the sand-fixing plate, and a plurality of holes 54 are formed on the hole template, and each hole is used for inserting a bar. The inner side length of the opening is 1cm-5cm.

[0090] The half-mold frame is similar to a W-shaped mold, and the opening template is a strip-shaped opening mold. The W-shaped mold and the opening mold are made of stainless steel plates. When the half-mould frame and the opening template are fixed together, the overall structure of the mold is formed ( T-die). Such as Image 6 As shown, the height of the T-shaped mold is ...

Embodiment 3

[0093] Utilize the magnesium cement mortar 6 in embodiment 1 and the method for the mold preparation connector of embodiment 2, may further comprise the steps:

[0094] Step 1, assemble the mold frame and the hole template;

[0095] Step 2, the rib in embodiment 1 is inserted in the opening, so that one end of the rib is located in the mold cavity, and the other end is positioned at the outside of the mold; the length of the rib reserved outside the mold is 5-20cm (this Embodiment reserves 7cm), such as Figure 7 shown.

[0096] Step 3, inject the magnesium cement mortar described in Example 1.1-1.3 into the mold cavity, and maintain in the air at 0-30°C until the magnesium cement mortar initially sets, preferably, maintain in the air for 8- 36h (the present embodiment curing time 24h) hardening;

[0097] Step 4: Disassemble and open the half-mold frame and the opening formwork, and the joints after demoulding are cured in the air at 0-30°C until the magnesium cement mortar...

Abstract

The invention discloses a connecting piece of a sand stabilization plates and a preparation method of the connecting piece. The connecting piece comprises a positioning plate formed by curing magnesium cement mortar and a reinforcing rib with one end cured at the inner bottom of the positioning plate, a groove allowing the sand stabilization plates to be inserted therein is formed in the top of the positioning plate, and the connecting piece of the sand stabilization plates is prepared through a mold forming method. The method comprises the following steps of assembling a mold frame and a trepanning template together; inserting a reinforcing rib into an open hole, so as to enable one end of the reinforcing rib to be positioned in a mold cavity, and positioning the other end of the reinforcing rib on the outer side of the mold; after magnesium cement mortar is initially set, injecting the magnesium cement mortar into the mold cavity, and maintaining the magnesium cement mortar in the air at 0-30 DEG C until the magnesium cement mortar is hardened; and detaching and opening half mold frames and the trepanning template, and conducting demolding to form the connecting piece of the sand stabilization plates. The preparation method is simple, and the connecting piece is low in cost and high in strength.

Description

technical field [0001] The invention relates to the technical field of sand fixing, in particular to a connector of a sand fixing board and a preparation method thereof. Background technique [0002] The sand fixation measures are to seal the sand sources and restrain the quicksand activities, so as to reduce or eliminate the damage to roads, railways and other facilities in the desert. Sand-fixing board is an important device for sand-fixing measures. However, the installation and operation of the current sand-fixing board is complicated, which affects the construction efficiency; or the sand-fixing board is directly fixed on the desert surface, and it is easy to be buried over time, which complicates secondary construction. [0003] For example, the patent application number 201811353228.3 discloses "a silica sol modified cellulose-based binder, an environmentally friendly water storage type sand-fixing board and its preparation method", and its operation method is to embe...
