[0026] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0027] like Figure 1 shown.

[0028] The construction process of the fish collecting tank bite pile of the present application includes the following steps:

[0029] The bite piles 1 are bored and cast in the rock and soil layer of the construction site, and the bite piles 1 enclose a fish collecting trough area. Then the inner side of the bite piles 1 is excavated downward. When the set depth is reached, the support angle brackets 2 are fixedly installed on the bite piles 1. There are two support angle brackets 2 at the same location that are distributed at intervals.

[0030] Then install the cross beam groove 3 on the supporting angle frame 2, and a pad 5 is installed on the inner side of the cross beam groove 3 relative to the prestressed steel pipe support 4. The prestressed steel pipe support 4 is installed on the supporting angle frame 2 to obtain support, and the end of the prestressed steel pipe support 4 supports the cross beam groove 3 through the pad 5. The prestressed steel pipe support 4 corresponds to the reinforcing component rod 31 of the cross beam groove 3.

[0031] A water-absorbing cushion layer 32 is laid inside the beam groove 3. The cushion layer 32 absorbs water, and then concrete is poured into the cushion layer 32 in the beam groove 3 to form a beam 33 after solidification. The beam 33 is separated from the inner side of the beam groove 3 by the cushion layer 32. When the beam 33 is disassembled later, the cushion layer 32 is used to isolate the beam 33, so that the concrete beam 33 will not be adsorbed into the beam groove 3 formed by the steel plate.

[0032] The present invention discloses a support structure for a fish collecting tank bite pile, comprising:

[0033] The interlocking pile 1 is formed by pouring reinforced concrete into the rock and soil layer of the construction site. The interlocking pile 1 is composed of a plurality of pile bodies interlaced, solidified and interlocked with each other.

[0034] The interlocking pile 1 is fixed with a support angle bracket 2 by means of expansion bolts. The support angle brackets 2 are two arranged at intervals. The two support angle brackets 2 support the bottom surface of the end of a prestressed steel pipe support 4 correspondingly.

[0035] A plurality of the support angle brackets 2 are spot-welded and fixed with a cross beam groove 3, and the cross beam groove 3 is a U-shaped groove formed by welding steel plates; a reinforcing force component rod 31 is welded in the middle of the cross beam groove 3, and the reinforcing force component rod 31 reinforces the middle of the cross beam groove 3, and a pad 5 is fixed on the inner side of the cross beam groove 3 with the reinforcing force component rod 31, and a prestressed steel pipe support 4 is installed on the support angle bracket 2, and the prestressed steel pipe support 4 contacts the inner side surface of the cross beam groove 3 through the pad 5.

[0036] A water-absorbing cushion layer 32 is laid inside the beam groove 3, and a beam 33 formed by solidified concrete is arranged in the cushion layer 32, and the cushion layer 32 is made of water-absorbing cotton. Before the concrete of the beam 33 is poured, the cushion layer 32 needs to be saturated with water to ensure that the concrete of the beam 33 is hydrothermally heated. When watering the concrete of the beam 33 in the later stage, the cushion layer 32 can also absorb water to ensure the curing effect of the beam 33.

[0037] After the inner side of the interlocking pile 1 is excavated downward to the designed depth, the prestressed steel pipe support 4 can support the interlocking pile 1 through the beam groove 3 formed by the prefabricated steel plate. In the later process of pouring concrete into the beam groove 3 and solidifying to form the beam 33, the downward excavation construction of the fish collecting trough is not affected, the construction efficiency is improved, and the problem that the cement pad construction needs to wait for solidification and stress on the cast-in-place pile to solidify, which is easy to affect the downward excavation construction efficiency of the fish collecting trough is solved.

[0038] During the downward excavation of the fish collecting tank, the concrete of the beam 33 is gradually solidified. After the beam 33 is completely solidified, the beam 33 together in the beam groove 3 resists and supports the lateral load of the bite pile 1.
