Embodiment 1

[0038] Combine below Figure 1 to Figure 7 The leak plugging assistant based on the explosive polymerization reaction and the method of use of the present invention are described in detail.

[0039] A plugging assistant based on explosive polymerization reaction, used for plugging exploration holes, a handle rod 10, at least one standard rod 20, one end rod 30, and an end rod 30 that are spirally connected from top to bottom. It includes an elastic filling bag 31 and a pointed cone 32. The elastic filling bag 31 is a closed structure. The outer side of the elastic filling bag 31 is evenly covered with friction thorns. The elastic filling bag 31 is separated into two juxtaposed by a blunt steel plate 33 arranged vertically. The storage room; the elastic filling capsule 31 is embedded between the lower end of the standard rod 20 and the upper end of the pointed cone 32, and the upper end of the pointed cone 32 passes through a solid shaft (not shown, set inside the blunt steel plat...

Embodiment 2

[0046] The difference from the first embodiment is that the standard rod 20 is provided with an elastic filling bag 31. Specifically, such as Image 6 As shown, in order to adapt to the plugging construction of exploration holes at different depths, the number of standard rods 20 can be increased or decreased accordingly; at the same time, in order to achieve a better plugging effect in the case of deeper exploration holes, you can While increasing the number of standard rods 20, increase the number of elastic filling bladders 31 from bottom to top, that is, elastic filling bladders 31 are provided in part of the standard rods 20 to achieve layer-by-layer sealing and gradually reduce water pressure Effect. Of course, each elastic filling bag 31 is connected with a wireless control device or a mechanical pull ring to facilitate the start of the explosive polymerization reaction inside the elastic filling bag 31, thereby improving the convenience of construction.

Embodiment 3

[0048] Correspondingly, this embodiment provides a method for using a plugging assistant based on an explosive polymerization reaction. Please refer to Figure 1 to Figure 7 , The use method of plugging assistant based on explosive polymerization reaction includes the following steps:

[0049] S001: The plugging assistant made by the factory is spare

[0050] S002: Insert the plugging assistant into a predetermined position in the exploration hole manually or mechanically;

[0051] S003: The blunt steel plate 33 is removed, the two storage chambers are connected, and the explosive polymerization reaction occurs when A and B contact, causing the elastic filling bag 31 to expand and generate friction with the hole wall of the exploration hole, thereby temporarily blocking the exploration hole ;

[0052] S004: Inject cement slurry to permanently plug the exploration hole.

[0053] Of course, according to the actual construction situation, after completing temporary plugging and performi...

Abstract

The invention relates to a leaking stoppage assistant based on explosive-polymerization reaction and a using method for the leaking stoppage assistant, belongs to the technical field of water resistance and impermeability of building foundation engineering. The leaking stoppage assistant is used for solving the problem that a conventional leaking stopping device cannot carry out site construction under a condition that water leaking pressure of an exploratory hole is large. The leaking stoppage assistant comprises a handle rod part, at least one standard rod part and an end part rod part which are spirally and rotatably connected in sequence from top to bottom, wherein the end part rod part comprises a sealed elastic filling bag and a pointed cone; the outer side of the elastic filling bag is uniformly coated with friction thorns; the elastic filling bag is divided into two parallel storage chambers by a blunt steel plate which is vertically arranged; the elastic filling bag is embedded between the standard rod part and the pointed cone; and the pointed cone and the standard rod are connected by a shaft center solid axle. The using method comprises: I, manufacturing the leaking stoppage assistant for later use in a factory; II, inserting the leaking stoppage assistant into a predetermined position in the exploratory hole; III, removing the blunt steel plate, and enabling A to be in contact with B to generate reaction, thereby expanding the elastic filling bag; and IV, injecting cement paste for plugging.

Description

Technical field [0001] The invention belongs to the technical field of waterproof and anti-seepage of building basic engineering, and particularly relates to a plugging assistant based on explosive polymerization reaction and a use method. Background technique [0002] Before the construction of the foundation pit project, the site will be surveyed, specifically by opening exploration holes to analyze and study the engineering geology of a certain area or a certain site. However, water leakage from exploration holes is a common engineering disease phenomenon in the process of foundation pit excavation. If the depth of the foundation pit is large, the water leakage pressure of the exploration hole is very high, and the water leakage from the exploration hole may seriously threaten the stability of the soil at the bottom of the pit. This will endanger the overall safety of the foundation pit and the stability of surrounding buildings. [0003] Currently, the commonly used blocking m...
