[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-2 A slide rail type steel plate box support system shown includes a support column group a1 and a support column group b5 installed at the rear side of the support column group a1;

[0025] The left and right opposite surfaces of the support column group a1 and the support column group b5 are both slidably connected with support bases 2;

[0026] A baffle b9 is connected between the support column group a1 and the support column group b5 and close to the upper side;

[0027] Baffle a10 is provided between the support column group a1 and the support column group b5 and is staggered near the lower side and baffle b9. When using the support, first dig a suitable deep pit on the ground, fix the support column group a1 and the support column group b5 respectively through the support base 2 in advance, then fix the support column group a1 and the support column group b5 inside the deep pit accordingly, fix the baffle b9 between the support column group a1 and the support column group b5, then push the support base 2 downward to the specified position, and continue to dig down to a suitable height by the excavator, push the positions of the support column group a1 and the support column group b5 and the baffle b9 downward, when the position of the top of the baffle b9 is only a short distance from the ground, insert the baffle a10 between the support column group a1 and the support column group b5 and slide it downward, and continue to dig downward to a suitable position for burying pipes or working by the excavator, and then push the baffle a10 downward to the bottom;

[0028] Through the design of this assembled steel box support system, the number of inserted baffles can be adjusted according to actual practical needs, thereby being able to adapt to deep pit supports of different depths.

[0029] like Figure 1 As shown, the front and rear end outer walls of the support column group a1 and the support column group b5 are fixedly connected with base limit holes 4, and the rear end outer walls of the support column group a1 and the support column group b5 are provided with sliding grooves 6 to cooperate with the base limit holes 4 to limit the up and down movement directions of the baffle a10 and the baffle b9, and the two support bases 2 are threadedly connected with an internal support 3 to increase the spacing between the support column group a1 and the support column group b5, and the right end outer walls of the two baffles a10 and the baffle b9 are provided with hook holes 8 that pass through the left and right.

[0030] The position and direction of baffle a10 and baffle b9 when sliding are limited by the base limit hole 4 and the slide groove 6 to avoid position displacement of baffle a10 and baffle b9 when sliding. When installing baffle a10 and baffle b9, the baffle a10 and baffle b9 can be installed and removed by hooking the hook hole 8 with an external crane.

[0031] like Figure 2 As shown, a rotating bearing 7 is embedded inside the support base 2, and the rotating bearing 7 can rotate freely inside the support base 2. In this way, when the support base 2 is plugged into the support pole group, the rotating bearing 7 can contact the side of the support base 2, thereby reducing the friction between the two, so that the support base 2 can be plugged into the support pole group more smoothly.

[0032] The implementation principle of this embodiment is: when using the support, first dig a suitable deep pit on the ground, fix the support column group a1 and the support column group b5 respectively through the support base 2 in advance, and then fix the support column group a1 and the support column group b5 correspondingly inside the deep pit, fix the baffle b9 between the support column group a1 and the support column group b5, and then push the support base 2 downward to the specified position, and continue to dig down to a suitable height by the excavator, and then push the position of the support column group a1 and the support column group b5 and the position of the baffle b9 downward. When the position of the top of the baffle b9 is only a short distance from the ground, insert the baffle a10 between the support column group a1 and the support column group b5 and slide it downward. At the same time, continue to dig downward by the excavator to a suitable position for burying pipes or working, and then push the baffle a10 downward to the bottom.
