[0009] As a further improvement of the basement floor pouring reinforcement system: the connecting rod is arranged obliquely, preferably, the included angle between the connecting rod and the horizontal plane is 50-80°. Thus, the strength of the poured floor is improved.

[0010] As a further improvement of the basement floor pouring reinforcement system: the anti-floating anchor rod further comprises a first supporting plate connected with the second horizontal rod, and the first supporting plate is supported on the cushion layer. Thus, the anchoring anti-floating capacity is improved while avoiding damaging the cushion layer.

[0011] As a further improvement of the basement floor pouring reinforcement system: a supporting rod for supporting the reinforcement mesh is further included. Thus, the reinforcement mesh is ensured to be supported everywhere.

[0012] As a further improvement of the basement floor pouring reinforcement system: the supporting rod is in an inverted U shape, the upper end of the supporting rod is provided with a groove matched with the reinforcement mesh, and the lower end of the supporting rod is provided with a third horizontal rod and a second supporting plate, and the second supporting plate is supported on the cushion layer. Thus, the supporting effect on the reinforcement mesh is improved while avoiding damaging the cushion layer.

[0013] As a further improvement of the basement floor pouring reinforcement system: a waterproof layer is arranged on the cushion layer. Thus, the groundwater is prevented from entering the basement, and the use safety of the basement is improved.

[0014] As can be seen from the above, the basement floor pouring reinforcement system has the advantages of simple structure, easy manufacturing, low cost and convenient use, effectively solves the technical problem of large amount of use of the existing technology, can simplify the detection of the lowering depth of the anti-floating anchor rod after drilling, improve the installation efficiency and subsequent grouting efficiency of the anti-floating anchor rod, thereby saving the construction cost, improving the economic benefit, and having strong practicability.
