[0016] In order to make the purpose, principle and structure of the present invention more clear, it is further described below with reference to the accompanying drawings and specific embodiments.

[0017] See also Figure 1 This embodiment provides a device for controlling the construction quality of precast concrete sheet piles, which mainly includes a hand hoist 1, a guide frame 2, and a clamp 3.

[0018] See also Figure 2 This equipment includes two hand hoists, each of which has a fixed hook 4 at both ends. The fixed hooks 4 at both ends are fixed on the guide frame 2 and the clamp 3 respectively. The chain of the hand hoist 1 is an iron chain, which is divided into two parts, including a hand chain 5 and a traction chain 6. The position of the clamp 3 is adjusted by pulling the hand chain 5 of the hand hoist 1, and the traction chain 6 controls the specific position of the clamp 3. The hand hoist 1 generally adopts a ratchet friction plate single-phase brake, which can brake by itself under load. The ratchet engages with the ratchet under the action of the spring, so that the brake works safely.

[0019] See also Figure 3The guide frame 2 uses two I-shaped channel steels, and a 25cm spacing is reserved between the two steel plates. The two I-shaped channel steels are used to limit the left and right sides of the concrete sheet piles. An integral frame is formed by welding on site. Support frames made of two I-shaped channel steels are set at both ends of the guide frame 2, with a length of 6m.

[0020] See also Figure 4 The first and second connecting plates 7 and 8 are respectively provided with two circular holes of the same size. The first and second connecting plates 8 are respectively provided with two horizontal connecting columns 9 for connecting the two vertically arranged steel plates. The connecting columns 9 are two steel rods of the same size. Each end of the steel rod passes through the circular holes provided on the steel plates and is fixedly connected. The steel rod at the bottom is clamped on the upper edges of the two I-channel steels so that the clamp 3 slides forward and backward on the I-channel steel. Four sets of bearings 10 are relatively provided on the steel rods to control the steel rods to be telescopically movable and axially rotated. The clamp 3 is used to limit the front and rear lateral positions of the concrete sheet piles.

[0021] The working principle of the device for controlling the construction quality of precast concrete sheet piles provided by the utility model is as follows:

[0022] The hand chain hoist 1, the guide frame 2 and the clamp 3 are used to form a device for controlling the construction quality of precast concrete sheet piles, which controls the adjacent two precast concrete panels to be squeezed and tightly connected. The clamp 3 is adjusted according to the reserved width between the guide frames 2, and the first connecting plate 7 and the second connecting plate 8 of the clamp 3 are respectively matched with the inner wall of the two I-shaped channel steels so that the lowest connecting column 9 is clamped on the upper edge of the two I-shaped channel steels, and the hand chain 5 of the hand chain hoist 1 is pulled according to the width of the precast concrete panel. The distance between the clamp 3 and the precast concrete panel is adjusted by the pulling chain 6, and the precast concrete panel is placed from top to bottom into the reserved gap. After the first precast concrete panel is placed, the distance between the clamp 3 and the first concrete panel is controlled again by adjusting the hand chain hoist 1 according to the width of the precast concrete panel, and the second precast concrete panel is placed. Next, the number of precast concrete panels to be placed is adjusted in sequence to squeeze the two adjacent precast concrete panels tightly connected, thereby controlling the construction quality of the precast concrete panel.
