Description

TECHNICAL FIELD

[0001] The utility model relates to grouting device technical field especially, it relates to a kind of large-area concrete pouring construction joint and crack grouting device. BACKGROUND

[0002] In the field of construction engineering, the pouring construction of large-area concrete is a common operating link, however, due to various factors, such as temperature change, foundation settlement, improper construction operation, etc., construction joints and cracks often appear in concrete structures, which not only affect the aesthetics of buildings, but more importantly, reduce the overall strength and durability of the structure, therefore, it is crucial to timely and effectively repair these construction joints and cracks.

[0003] Traditional repair methods mostly use manual grouting, which is inefficient and the grouting effect is difficult to guarantee. With the development of technology, some automated grouting equipment has been gradually applied in actual engineering, but these devices still have many problems.

[0004] Firstly, the construction site is often uneven, which brings great challenges to the stability of the grouting equipment during movement. The grouting equipment is prone to tilt when moving on uneven ground, which may cause safety accidents and damage to construction personnel and equipment.

[0005] In addition, during the use of the grouting equipment, feeding the material tank is a key step. In order to ensure the smooth entry of materials, the feed valve and pressure relief valve need to be opened at the same time. However, in the existing grouting equipment, the opening of these two valves usually needs to be operated separately, which not only increases the complexity of operation, but also may cause negligence and errors during operation, thereby affecting subsequent engineering.

[0006] Furthermore, the material tank, as the core component of the grouting equipment, is equipped with a stirrer inside to ensure the uniformity of the grouting material. However, in actual use, concrete residues are still likely to remain on the tank wall. These residues will gradually clump after a long period of accumulation, which not only affects the cleanliness and service life of the material tank, but also may adversely affect the quality and performance of the grouting material.

[0007] Therefore, the applicant proposes a large-area concrete pouring construction joint and crack grouting device to solve the above technical problems. CONTENT OF THE UTILITY MODEL
