Description

Technical Field

[0001] This utility model relates to the field of engineering construction, specifically to an underwater grouting device. Background Technology

[0002] Underwater grouting equipment is a specialized device used for grouting operations in underwater engineering. It mixes water, cement and other media into a uniform grout. The grout has advantages such as good fluidity, high stability and injectability, adjustable setting time, no shrinkage during curing, and no need for vibration during grouting. The underwater grouting pump is the core equipment for underwater grouting operations. Usually, the grouting is done from the outside first and then the inside is poured.

[0003] However, since grouting is done in a segmented pouring method, a specific funnel is required when pouring on the outside, and the grout is prone to flow on one side during pouring, which affects the molding rate. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an underwater grouting device that solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an underwater grouting device, including a grouting template and a grouting funnel. The lower end of the grouting funnel is provided with an inner grouting hole. An outer grouting hole is provided in a ring array on the lower surface of the grouting funnel on the outer side of the inner grouting hole. An outer grouting plug is provided inside the outer grouting hole. An inner grouting plug is provided inside the inner grouting hole. A bottom washer is installed on the lower surface of the outer grouting plug. A limiting pad is installed on the outer side wall of the bottom washer. A locking screw is installed on the upper surface of the limiting pad. A limiting ring is installed on the outer side of the locking screw corresponding to the side surface of the grouting funnel.

[0006] As a further embodiment of this utility model: the grouting template includes: an outer sleeve, a reinforcing cage, and an inner sleeve.

[0007] As a further improvement of this utility model, the outer diameter of the bottom washer is smaller than the inner diameter of the outer sleeve.

[0008] As a further improvement of this utility model, the outer diameter of the inner grouting hole is smaller than the inner diameter of the inner sleeve.

[0009] As a further improvement of this utility model, a limit nut is installed on the outer side of the locking screw.

[0010] As a further improvement of this utility model, the outer diameter of the external grouting plug matches the inner diameter of the external grouting hole.

[0011] As a further improvement of this utility model, hooks are installed in a ring array on the upper surface of the grouting funnel.

[0012] As a further improvement of this utility model, the outer diameter of the inner grouting plug matches the inner diameter of the inner grouting hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. During grouting, the inner grouting plug is inserted into the inner grouting hole from the top of the grouting funnel to seal it. After the outer grouting plug is removed from the outer grouting hole, the mixed grout is poured into the grouting funnel from the top. The grout is then injected into the gap between the outer sleeve and the inner sleeve through the outer grouting plugs arranged in a ring array inside the grouting funnel, ensuring the efficiency of grouting.

[0015] 2. The external and internal grouting holes on the grouting funnel can be closed and opened, so the grouting funnel can perform internal and external grouting treatment in one go. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, this embodiment provides an underwater grouting device, including a grouting template 1 and a grouting funnel 2. An inner grouting hole 202 is provided at the lower end of the grouting funnel 2. An outer grouting hole 201 is arranged in a ring array on the lower surface of the grouting funnel 2, outside the inner grouting hole 202. An outer grouting plug 204 is provided inside the outer grouting hole 201. The outer diameter of the outer grouting plug 204 matches the inner diameter of the outer grouting hole 201. The inner grouting hole 202 is provided with… The inner grouting plug 203 has an outer diameter that matches the inner diameter of the inner grouting hole 202. A bottom washer 205 is installed on the lower surface of the outer grouting plug 204. A limiting plate 207 is installed on the outer side wall of the bottom washer 205. A locking screw 208 is installed on the upper surface of the limiting plate 207. A limiting nut is installed on the outer side of the locking screw 208. A limiting hanging ring 206 is installed on the outer side of the locking screw 208 corresponding to the side surface of the grouting funnel 2.

[0024] like Figure 2-3 As shown, in this embodiment, the grouting template 1 includes: an outer sleeve 101, a reinforcing cage 102, and an inner sleeve 103. The outer diameter of the bottom washer 205 is smaller than the inner diameter of the outer sleeve 101. The outer diameter of the inner grouting hole 202 is smaller than the inner diameter of the inner sleeve 103. The upper surface of the grouting funnel 2 is equipped with hooks 3 arranged in a ring array.

[0025] The working principle of this utility model is as follows: During use, a grouting template 1 is placed at a predetermined grouting position, and a reinforcing cage 102 is installed between the outer sleeve 101 and the inner sleeve 103. During grouting, the inner grouting plug 203 is inserted from above the grouting funnel 2 into the inner grouting hole 202 for sealing. After removing the outer grouting plug 204 from the outer grouting hole 201, the hook 3 on the upper surface of the grouting funnel 2 is used to lift it above the grouting template 1. Then, the inner grouting hole 202 is inserted into the inner sleeve 103. The mixed grout is then poured into the grouting funnel 2 from above, forming a ring-shaped flow inside the grouting funnel 2. The outer grouting plug 204 is installed to inject grout into the gap between the outer sleeve 101 and the inner sleeve 103. After the grouting is completed, the inner grouting plug 203 is disassembled by lifting the grouting funnel 2 upwards. The outer grouting plug 204 is then inserted into the outer grouting hole 201 from below the grouting funnel 2. The locking screw 208 is then inserted into the limiting ring 206 on the outside of the grouting funnel 2. The outer grouting plug 204 is then limited by the limiting nut. Grout is then injected from inside the grouting funnel 2 to inject grout into the inner sleeve 103 from the inner grouting hole 202. After the grout is stabilized, the inner sleeve 103 and the outer sleeve 101 are removed in sequence.
