[0002] During the water construction process of H-shaped sheet piles in HZ composite sheet piles, sometimes it is difficult to penetrate the soil layer. It is difficult to drive the pile with a vibratory hammer, and the pile foundation is difficult to penetrate the soil layer. At this time, a vibratory hammer with a larger power can be used or a percussion hammer can be used in cooperation with a pile cap to achieve the pile driving operation. However, due to the lack of local resources in some countries, it is impossible to dispatch a new vibratory hammer to the site in the short term; moreover, the local conditions do not allow the processing of pile caps, and it is necessary to import pile caps from our country and transport them to the site. This method is costly and time-consuming, and will seriously affect the construction period. Summary of the Invention

[0006] Preferably, a reinforcing plate is fixed above the fixing plate inside the tubular main body, and the reinforcing plate is composed of two longitudinally crossed steel plates.
[0007] Preferably, a clamping plate for clamping the H-shaped sheet pile is fixed below the fixing plate inside the tubular main body.
[0008] Preferably, the clamping plate includes a transverse clamping plate, a longitudinal clamping plate, and an inclined clamping plate, and the longitudinal clamping plate is parallel to the connection line of the two slits.

[0016] Figure 2 is the exploded view of the pile driver;
[0017] Figure 3 is the top view of the pile driver. DETAILED DESCRIPTION OF THE INVENTION
[0018] The technical solution of the present utility model will be further described below in conjunction with embodiments.
[0019] As shown in the figure, the pile driver for constructing the H-type sheet pile of the present utility model includes a tubular body 1 driven by a power mechanism and a fixing plate 2 passing through the tubular body 1 for transmitting load to the H-type sheet pile. Two gaps 3 for sleeving the H-type sheet pile are symmetrically opened on the side wall of the tubular body 1 below the fixing plate 2. The connection line of the two gaps 3 passes through the diameter of the tubular body 1.
[0020] Above the fixing plate 2 inside the tubular body 1, a reinforcing plate 4 composed of two longitudinally crossed steel plates is fixed, which is beneficial to improving the stability and bearing capacity of the fixing plate 2.
[0021] Below the fixing plate 2 inside the tubular body 1, a clamping plate 5 for clamping the H-type sheet pile is fixed, which is beneficial to strengthening the clamping force and stability of clamping the H-type sheet pile.
[0022] The clamping plate 5 includes a transverse clamping plate 51, a longitudinal clamping plate 52 and an inclined clamping plate 53, and the longitudinal clamping plate 52 is parallel to the connection line of the two gaps 3.
[0023] The points where the clamping plate 5 contacts the inside of the tubular body 1 are welded to the tubular body 1.
[0024] A number of longitudinal plates 6 and transverse plates 7 for increasing the overall strength and bearing capacity of the pile driver are provided around the tubular body 1.
[0025] Two lifting lugs 8 are symmetrically arranged along the diameter direction on the outside of the tubular body 1.
[0026] Reinforcing plates 9 are fixed on the fixing plates 2 both inside and outside the tubular body 1, for strengthening the connection between the fixing plate 2 and the tubular body 1.
[0027] The fixing plate 2, the reinforcing plate 4, the clamping plate 7, and the reinforcing plate 9 are steel plates.
[0028] The working principle of the pile driver for constructing H-shaped sheet piles according to the present utility model is as follows: Vertically place the pile driver on the barge, lift the impact hammer with a crane and place it above the pile driver, slowly lower the impact hammer so that it is sleeved inside the tubular body 1 of the pile driver, pass a steel wire rope through the lifting lug 8 of the pile driver and connect the impact hammer and the pile driver together. Lift the impact hammer with the pile driver to the pile position, slowly lower it, and adjust the direction of the pile driver so that the two gaps 3 on the side wall of the pile driver just sleeve the vertical steel plates of the H-shaped sheet pile, and the clamping plate 5 clamps the vertical steel plates of the H-shaped sheet pile. The two transverse steel plates of the H-shaped sheet pile are outside the tubular body 1, and then the pile driver is sleeved into the H-shaped sheet pile. Slowly lower the impact hammer so that it completely lands on the pile driver, loosen the upper sling and start driving the H-shaped sheet pile. The pile driver transmits the impact force to the H-shaped sheet pile, enabling it to penetrate through relatively hard soil layers until the design elevation, greatly improving the pile driving efficiency of the H-shaped sheet pile.
