Description

Technical Field

[0001] The utility model relates to a water construction device, in particular to an auxiliary device for butt-jointing composite sheet piles. Background Art

[0002] When domestic projects carry out water steel sheet pile construction, generally a pile driving vessel is adopted and equipped with a pile driving frame. However, in foreign hydraulic projects, limited by local resources and the high cost of ship dispatching, for water composite sheet piles (referred to as H sheet piles and Z sheet piles in this article), a construction process of lifting and driving with a crawler crane + a vibratory hammer + a positioning frame is generally adopted. Therefore, there is a problem of butt-jointing between the main H sheet pile and the auxiliary Z sheet pile during the construction process. According to local construction experience abroad, the conventional construction method usually uses a crane to hoist a mobile hanging basket, and auxiliary personnel tighten the towing rope to reduce the sway of the hanging basket, and the operator conducts auxiliary butt-jointing of the main and auxiliary sheet piles in the hanging basket. Using this method for construction will result in poor stability of the hanging basket, still there is a swaying situation, reducing the butt-jointing work efficiency, and there is a certain risk.

Hooks are respectively fixedly arranged on the outer sides of two of the longitudinal brackets, and the hooks are fixed on the same side and on the two longitudinal brackets connected with the longer horizontal bracket.

[0005] Preferably, the highest point of the hook is lower than the highest point of the horizontal bracket.

[0007] Preferably, a horizontal steel pipe is transversely fixed on the longitudinal bracket to enhance the stability of the auxiliary device.

[0008] Preferably, a plurality of short reinforcing bars and two long reinforcing bars for strengthening the strength of the auxiliary device are fixed on the bottom plate.

[0009] Preferably, the short reinforcing bars are parallel to the short side of the bottom plate, and the long reinforcing bars are parallel to the long side of the bottom plate.

[0010] Preferably, a stiffening plate for enhancing the stability and strength of the auxiliary device is arranged between the short reinforcing bar in contact with the longitudinal bracket and the longitudinal bracket.

[0011] Preferably, the longitudinal support, horizontal support, short reinforcing rod, long reinforcing rod and stiffening plate are all made of 12# channel steel.

[0012] Preferably, the bottom plate is made of 17 mm thick bamboo plywood.

[0013] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: (1) The device uses a rectangular steel structure frame instead of a hanging basket and a hook instead of a traction rope, which can enhance stability during construction and ensure the safety of construction workers; (2) The highest point of the hook in the device is lower than the highest point of the horizontal bracket of the device, so that when the device is hung on the steel sheet pile, a part of it exceeds the top surface of the steel sheet pile, and the exceeding part can be used as a reference surface when the main and auxiliary sheet piles are locked and aligned, thereby improving the efficiency of pile alignment; (3) According to the pile position of the H main pile, two hooks are set so that it can be hung on the H main pile that has been driven, and has sufficient operating space and stability, avoiding the impact of shaking on the operators; (4) The length of the device is longer than the distance between adjacent H main piles. The device can be positioned once to dock with multiple Z auxiliary sheet piles, greatly improving the efficiency of pile alignment. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the utility model is further described below in conjunction with embodiments.

[0019] As shown in the figure, the auxiliary device for jointing of combined sheet piles described in the utility model includes a base plate 1, a plurality of longitudinal brackets 2 fixed on the base plate 1 in the vertical direction, a horizontal bracket 3 arranged parallel to the base plate 1 and fixedly connected to the longitudinal brackets 2, and hooks 4 are respectively fixed on the outer sides of two of the longitudinal brackets 2, and the hooks 4 are fixed on the two longitudinal brackets 2 on the same side and connected to the longer horizontal bracket 3.

[0020] The highest point of the hook 4 is lower than the highest point of the horizontal support 3 .

[0021] Two lifting ears 5 for lifting the auxiliary device to a designated position are fixed on the two longer horizontal brackets 3 respectively.

[0022] A horizontal steel pipe 6 is fixedly mounted transversely on the longitudinal support 2 to enhance the stability of the auxiliary device.

[0023] A number of short reinforcing bars 7 and two long reinforcing bars 8 for strengthening the strength of the auxiliary device are fixedly mounted on the bottom plate 1.

[0024] The short reinforcing bars 7 are parallel to the short sides of the bottom plate 1, and the long reinforcing bars 8 are parallel to the long sides of the bottom plate 1.

[0025] A stiffening plate 9 for enhancing the stability and strength of the auxiliary device is provided between the short reinforcing bar 7 in contact with the longitudinal support 2 and the longitudinal support 2.

[0026] The longitudinal support 2, the horizontal support 3, the short reinforcing bars 7, the long reinforcing bars 8, and the stiffening plate 9 are all made of 12# channel steel.

[0027] The bottom plate 1 is made of a 17-mm-thick bamboo plywood.

[0028] The working principle of the auxiliary device of the present utility model is as follows: During actual construction, first drive the H main sheet piles into the water. There will be a height difference between adjacent two H main sheet piles due to construction errors. After the construction of the H main sheet piles is completed, hang a steel wire rope on the hook of the crane. The steel wire rope then suspends the lifting lug on the auxiliary device through a snap ring, lift the auxiliary device with operators standing on it and make it fall on the H main sheet piles, so that the hook on the auxiliary device hangs on the separated H main sheet piles. At this time, lift the Z auxiliary sheet pile and make it close to the auxiliary device, then the locking mouths of the main and auxiliary sheet piles are on the same straight line. Loosen the steel wire rope of the crane and slowly lower the Z auxiliary sheet pile. The operator assists in docking one side of the locking mouth of the Z auxiliary sheet pile to make it slide into the locking mouth of the higher-side H main sheet pile. Since the highest point of the hook in this device is lower than the highest point of the horizontal support of the device, when this device is hung on the steel sheet pile, a part of it extends beyond the top surface of the steel sheet pile, and the extended part can be used as a reference surface when aligning the locking mouths of the main and auxiliary sheet piles, thereby improving the pile alignment efficiency. Then the operator uses a tensioner or a chain block to make the other side of the locking mouth of the Z auxiliary sheet pile enter the locking mouth of the lower-side H main sheet pile, and the docking is completed.

[0029] The distance between the two hooks on this device can be adjusted according to the distance between the main sheet piles. The length of this device can also be adjusted according to actual needs. When its length is greater than the distance between two main sheet piles, positioning it once can dock multiple auxiliary sheet piles.
