Description

Technical Field

[0001] The utility model relates to the technical field of SMW pile construction, in particular to a coating device for improving the SMW pile construction efficiency. Background Art

[0002] With the rapid development of the national economy, resource and energy issues are becoming the main problem restricting growth. Therefore, the State Council has timely put forward policies to build a conservation-oriented society and develop a circular economy. The main methods for the civil construction industry to achieve the above goals are: strive to use construction materials that can be turned over in construction and adopt construction processes that ensure that construction materials can be reused, realize recycling, improve resource utilization, and minimize the use of construction processes that consume disposable materials.

[0003] The H-beam of the SMW method can be reused, generally at least four times. However, in the construction process of underground continuous wall and bored pile as enclosure, a large amount of steel bars are used, which cannot be recycled and reused, resulting in a huge consumption of steel resources. my country has become the world's largest steel producer and consumer, and my country's steel dependence on foreign countries is very high, mainly reflected in the shortage of iron ore resources, most of which need to be imported. Therefore, it is necessary to try to adopt construction processes such as the SMW method that can reduce the consumption of resources such as steel.

[0004] Although the SMW method still has the above-mentioned problems and focuses of attention in its application, as a new technology to be promoted and applied, under the premise of meeting the engineering technical requirements, the SMW method is selected as the retaining structure, which has incomparable advantages over underground continuous walls and bored piles plus waterproof curtains as retaining structures. Therefore, as investors and designers, after technical and economic comparison, they generally give priority to the SMW method as the retaining structure. Therefore, as a construction company, it is necessary to strengthen the construction management and technical innovation of the SMW method. How to improve construction efficiency, improve construction quality, and save construction time during the construction process is the main problem to be solved by the construction unit. Summary of the invention

[0005] In view of the above-mentioned prior art, the utility model proposes a coating device for improving the construction efficiency of SMW method piles.

[0006] The utility model provides a coating device for improving the construction efficiency of SMW piles, comprising a storage box for storing a friction reducer, a friction reducer outlet being arranged at the bottom of the storage box, a brush being arranged at the bottom of the storage box at the lower end of the friction reducer outlet, and a handle being arranged at one side of the storage box.

[0007] Preferably, the friction reducer outlet is arranged in the middle of the bottom of the storage box and is arranged along the length direction of the storage box.

[0008] Preferably, the brush is made of plastic.

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0015] Example: Figure 1 A coating device for improving the efficiency of SMW pile construction is shown, comprising a storage box 1, the storage box 1 is used to store a friction reducer, a friction reducer outlet 2 is arranged in the middle of the bottom of the storage box 1, the friction reducer outlet 2 is arranged along the length direction of the storage box 1, a plastic brush 3 is arranged at the bottom of the storage box 1 at the lower end of the friction reducer outlet 2, a handle 4 is arranged at the lower part of one side of the storage box 1, the handle 4 is a wooden stick, and the handle 4 is connected to the storage box 1 by two screws 5.

[0016] The coating device is applied to improve the construction efficiency of SMW piles, and the construction method includes the following steps:

[0017] Step 1: The surface of the I-beam is ground upon arrival. If the required length of the H-beam is not enough, it needs to be welded. The welds are all full-groove welds. After welding, use a grinding wheel to grind the welds until they are as flat as the steel surface.

[0018] Step 2: After welding and grinding the I-beam, start applying the friction reducer. First, heat the friction reducer material with an electric heating rod until it is completely melted. Stir it with a stirring rod until the thickness is even before applying it to the H-beam.

[0019] Step 3: After the friction reducer is heated, use the brushing device to pour the friction reducer into the storage box 1, push the brush forward, and use a crane to turn over the other side after one side is constructed, and continue to brush. The brushing device can greatly improve the efficiency of friction reducer coating and ensure uniform thickness, ensuring that the I-beam can be inserted within 30 minutes after the three-axis pile is formed, and then the construction of the next pile can be started.

[0020] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
