Description

Technical Field

[0001] The utility model relates to the technical field of highway bridges and municipal roads, in particular to a device for lifting steel sheet piles to tightly bite. Background Art

[0002] In the field of subway and highway transportation construction, steel sheet piles can be used for support and slope protection. In the field of water engineering, steel sheet piles can be used for river channel construction and embankment reinforcement. In the field of construction engineering, steel sheet piles can be used for foundation support and basement construction surface. With the development of sponge cities, more and more cities will upgrade and renovate urban infrastructure, and more and more underground pipelines will be re-excavated and renovated. At present, the most commonly used in China is Larsen steel sheet pile, which has the characteristics of low cost, short cycle, reusability, and effective water isolation. However, in the traditional point-by-point driving method, the steel sheet pile requires a worker to stand under the pile driver to manually assist the driver to align the bite position. The workers below have to endure huge vibrations and noise, and if the pile driver fails, the steel sheet pile falls, which is likely to hit the workers below. In addition, the pile body is easy to tilt during the driving process, and it is not easy to correct after the error accumulates, and the steel sheet pile is difficult to bite. In the traditional screen-type driving method, a guide frame is first set up, and then the steel sheet pile frame is erected. The pile driver needs to be moved to drive the piles on both sides into half the designed depth, and then the middle steel sheet pile is driven in sequence. Finally, the pile driver needs to be moved to drive the steel sheet pile into the designed depth. This pile driving method has a very slow construction speed and requires the construction of a higher construction pile frame. As for the rainwater box culvert constructed in this project, the construction period is short and the length of the rainwater box culvert is long. It is necessary to drive in more than 700 meters of steel sheet piles. This is a very large project, and the foundation pit excavation is more than 8m. The inner diameter of the box culvert is 5.6m*3m and the wall thickness is 60cm. A large amount of reinforced concrete is required. Rebar binding, concrete pouring and maintenance all take a lot of time. If it rains, the uninterlocked steel sheet piles cannot effectively block water, and water seepage or even collapse will definitely occur in the foundation pit. Not to mention that the construction period is greatly extended, there are also great safety hazards for the workers below. Therefore, it is very necessary to quickly drive in tightly interlocked steel sheet piles during construction. Utility Model Content

[0024] A connecting structure is set on the ground for connecting and fixing the mold structure. The connecting structure is used to fix the mold structure in a mirror image. The steel sheet piles are clamped by the mold structure to ensure that the steel sheet piles will not be detached during the piling process of the pile driver. The mold structure is used to stabilize the steel sheet piles.

[0025] like Figure 2-4 As shown, the connection structure includes a bearing unit arranged on the ground for connecting with the mold structure, the bearing unit is used to connect the mold structure, drive the mold structure to translate and cooperate with the interlacing unit to fix the mold structure, and the interlacing unit is arranged on the bearing unit, the interlacing unit is used to insert the bearing unit to fix the two connection structures, thereby fixing the two mirrored mold structures, the bearing unit includes a guide beam 6 arranged on the ground, the guide beam 6 is the basic structure of the bearing unit, the guide beam 6 is welded to the template 4 to ensure that the driven steel sheet pile is linear and straight, the number of guide beams 6 is two, the two guide beams 6 are connected to the template 4 and are mirrored, and are connected by two cross pins 1, and a guide beam reserved opening 5 is opened on the guide beam 6, and the guide beam reserved opening 5 is provided. The opening 5 is used to insert the cross pin 1. The diameter of the guide beam reserved opening 5 is consistent with the diameter of the cross pin 1.
