Embodiment Construction

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] see Figure 1-6 As shown, a new process for deep hole blasting and sealing, the process includes the following steps:

[0033]S1. First, a deep hole 2 is opened at the construction site 1, and then the explosive is filled in the explosive layer 10 at two-thirds of the deep hole 2, and one third of the deep hole 2 is reserved as a sealing section , install the hole sealer into the hole sealing section at deep hole 2;

[0034] S2. Set the grouting pipe 5 on the rubber connecting sleeve 7 through th...

Abstract

The invention discloses a new technology for sealing holes in deep hole blasting. The technology includes the following steps: firstly, a deep hole is opened at the construction site, and then two thirds of the explosive layer of the deep hole is filled with explosives; Set the grouting pipe on the rubber connecting sleeve, and then install the pouch by holding the handle on the pouch locker; put the pouch into the sealing section of the deep hole, and press the sealing material The water-cement ratio is 1:1 and the mixture is mixed, and the grouting pipe is connected to the grouting pump, and then the sealing material is injected into the pouch along the grouting pipe and the grouting pipe through the grouting pump, so that the pouch is bulged And block the hole-sealing section, stop the grouting when the pressure gauge shows that the pressure is 2MP, and then blast the hole-sealing material in the bladder 3 after solidifying for 20 minutes; the present invention solves the problem of punching holes; The blasting energy is concentrated; the construction process of workers is simplified, the construction time is shortened, the operation is simple, safe and reliable, the strength of the sealing material is guaranteed, and the advantages are economical and applicable.

Description

technical field [0001] The invention belongs to the technical field of blasting, and relates to a new technology for hole sealing, in particular to a new technology for deep hole blasting and hole sealing. Background technique [0002] With the vigorous development of infrastructure construction, blasting engineering is widely used in excavation engineering, tunnel engineering, urban building structure demolition engineering and other blasting operations. [0003] The reference document CN208780033U discloses a hole sealing device for blasting engineering, which includes a cantilever and a hole sealing. Both ends of the bottom of the cantilever are fixedly connected to the ground through flanges. There are several wooden wedges at equal distances inside, and a hollow conduit is inserted into the middle of several wooden wedges. The interior of the hollow conduit is slidably connected with a piston. The top of the piston is connected to the telescopic end of the electric tele...
