In addition, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] As Figures 1 to 5 shown, the formwork (hereinafter referred to as the formwork) for the concrete pouring of river slope protection in the embodiment of the present utility model includes a back rib frame 1 and a steel formwork 2. The back rib frame 1 is provided with a groove 101 with an upward opening, and a hydrophobic and breathable material 3 is filled in the groove 101. Among them, a plurality of independent frames 102 are formed by enclosing between adjacent grooves 101 on the back rib frame 1. The upper ends of the respective frames 102 are fixedly installed with steel formworks 2, that is, the steel formworks 2 are arranged at intervals from each other, so that the upper surface of the steel formwork 2, the upper end surface of the back rib frame 1, and the upper end surface of the hydrophobic and breathable material 3 are all in the same plane, and this plane is the front of the formwork. When in use, the front of the formwork is set close to the concrete, and then the concrete is vibrated with an inserted vibrator, so that the air bubbles discharged from the concrete can be discharged from the hydrophobic and breathable material 3.

[0032] Thus, the formwork for the concrete pouring of river slope protection in the embodiment of the present utility model overcomes the problem that air bubbles cannot be discharged during the pouring of slope concrete with traditional wooden formworks and steel formworks. When pouring concrete, the vibrated air bubbles can escape from the concrete along the hydrophobic and breathable material, thereby reducing problems such as honeycombing, pitting, and cavities on the slope concrete and ensuring the appearance forming quality of the slope concrete.

[0033] Specifically, a plurality of bolt holes 4 are provided at intervals on the formwork for concrete pouring of the river slope protection in the embodiment of the present utility model.

The outer frame 5 is connected and fixed to the outer steel formwork 2, and the upper end of the outer frame 5 is flush with the upper surface of the steel formwork 2, and the lower end of the outer frame 5 is flush with the lower end surface of the back rib frame 1.

[0035] Among them, the outer frame 5 is of a rectangular structure, and a plurality of pin holes 6 are provided on the four side edges of the outer frame 5. By providing the pin holes 6, a plurality of formworks are spliced by pins to form a formwork with a larger area to match the use of slope concrete pouring.

[0036] Among them, the back rib frame 1, the steel formwork 2 and the outer frame 5 can be set as an integrally formed structure, so as to ensure that the formwork structure of this embodiment has good structural stability and reliability, and to ensure better flatness of the front surface of the formwork.

[0037] In some embodiments of the present utility model, the back rib frame 1 is formed by connecting a plurality of transverse back ribs 1A and a plurality of longitudinal back ribs 1B. A rectangular frame 102 can be formed by enclosing between adjacent transverse back ribs 1A and adjacent longitudinal back ribs 1B.

[0038] Among them, the transverse back rib 1A includes a transverse back rib bottom plate 11A and two transverse back rib side plates 12A. A transverse back rib groove 101A with an upward opening is formed by enclosing between the transverse back rib bottom plate 11A and the two transverse back rib side plates 12A. Among them, the longitudinal back rib 1B includes a longitudinal back rib bottom plate and two longitudinal back rib side plates. A longitudinal back rib groove 101B with an upward opening is formed by enclosing between the longitudinal back rib bottom plate and the two longitudinal back rib side plates, and each transverse back rib groove 101A communicates with each longitudinal back rib groove 101B respectively.

[0039] Among them, the steel formwork 2 is of a rectangular structure adapted to the frame 102. The four sides of the steel formwork 2 are respectively fixedly connected to the upper ends of the corresponding transverse back rib side plates 12A and longitudinal back rib side plates used to enclose the frame 102 to ensure that the upper surface of the steel formwork 2 is flush with the upper end surface of the back rib frame 1.
