Description
Technical Field
The invention relates to the technical field of buildings, in particular to a novel self-heating type leaking stoppage capsule.
Background
When leakage occurs at the settlement joint of the underground building structure, the traditional method is to adopt the oil-based polyurethane plugging agent material to perform grouting plugging through a high-pressure grouting machine.
The leak stopping process has the advantages that; the oil-based polyurethane plugging material is a single component and can be poured into a high-pressure grouting machine to perform plugging operation without blending. The oily polyurethane plugging agent is injected into a settlement joint and can generate foaming expansion phenomenon when meeting water or air, the expansion volume can reach 30 times, the foaming reaction starts when meeting water or air at normal temperature for 2-3 minutes, the appearance after the expansion foaming is very similar to that of a foaming agent in daily life, but the foaming of polyurethane grouting liquid is different in high foaming strength and hardness, and the polyurethane plugging liquid can be foamed when meeting water, so that a water leakage channel is effectively plugged, the plugging and repairing function is achieved, the effect is fast, and the construction is flexible, convenient and fast.
The defect of the plugging process is that; because the polyurethane plugging agent is injected into the settlement joint of the underground structure to generate expansion foaming to effectively plug a water leakage channel, the defect that a brittle body formed after the material is expanded has no flexibility and elasticity is the greatest defect, the settlement joint of the underground structure is the joint of two building structures, uneven settlement is inevitable, and the settlement joint of the two structures is changed, so the polyurethane plugging agent has the defects of no elasticity and no flexibility, the settlement joint has settlement change for a while, the original polyurethane plugging material fails to continuously leak water, and the water leakage cannot be effectively cured.
An effective solution to the problems in the related art has not been proposed yet.
Disclosure of Invention
The invention aims to provide a novel self-heating type leaking stoppage capsule to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a novel from fever type leaking stoppage capsule, includes non-curing waterproof coating, heating band and biological environmental protection degradation membrane, non-curing waterproof coating is the sausage shape, and diameter 3 centimeters, length 30 centimeters one section, every 5 sections are one, and 1.5 meters, non-curing waterproof coating's central point penetrates the heating band, non-curing waterproof coating's outside cladding has biological environmental protection degradation membrane.
Furthermore, the width of the heating belt is 8mm, the power is 20W, and the self-limiting temperature is less than or equal to 70 ℃.
Further, the biological environment-friendly degradable film is a water-soluble degradable film.
A use method of a novel self-heating type leaking stoppage capsule comprises the following steps: the field worker inserts the plugging capsule into the settlement joint by hand to perform plugging operation, the heating belt is used for electric heating to enable the non-solidified waterproof coating in the capsule to flexibly flow out to enter the settlement joint to perform plugging, the field worker can directly take the plugging capsule, and the heating belt is used for heating to enable the non-solidified waterproof coating to flexibly extrude into the settlement joint to perform plugging.
Compared with the prior art, the invention has the following beneficial effects:
1. and (3) non-curing: the solid content is up to more than 98 percent, almost no volatile matter exists, and the elastic colloid is always kept in an application state.
2. Excellent self-healing properties: when the waterproof layer receives external force to destroy, the damaged point can not enlarge, has the creep effect and can repair the damaged point gradually, improves the waterproof layer reliability greatly.
3. Excellent ductility: high elongation of 1000% or more, no damage caused by displacement, and good sealing and water-proof state of the structure
4. Excellent creep properties: the problems of waterproof fracture, flexural fatigue or advanced aging under a high stress state and the like caused by the fact that the cracking stress of the base layer is transmitted to the waterproof layer can be solved.
5. Excellent adhesion properties: can be constructed on a wet base surface, can be bonded with base surfaces of almost any material,
6. excellent chemical resistance and ageing resistance: the performance after the soaking test in acid, reducing and salt medium and the heat aging treatment is kept above 90 percent.
The efficiency and the use convenience of leaking stoppage can be greatly improved.
Detailed Description
The invention will be further described with reference to specific embodiments:
the novel self-heating type leaking stoppage capsule comprises a non-curing waterproof coating, a heating belt and a biological environment-friendly degradable film, wherein the non-curing waterproof coating is in a sausage shape, the diameter of the non-curing waterproof coating is 3 cm, the length of the non-curing waterproof coating is 30 cm, each 5 sections of the non-curing waterproof coating are one, and each section of the non-curing waterproof coating is 1.5 meters, the heating belt penetrates through the center part of the non-curing waterproof coating, the biological environment-friendly degradable film is coated outside the non-curing waterproof coating to prevent hands from being stuck, and field workers can insert the leaking stoppage capsule into a settlement joint by hands to perform leaking stoppage operation.
The specific operation method comprises the following steps: if asphalt is used as a non-curing waterproof coating, a layer of biological environment-friendly degradable film is wrapped outside, the environment-friendly plastic has the characteristics of degradability, the environment-friendly plastic is melted when meeting water and is not melted when meeting oil, after the non-curing waterproof plugging material is poured, the shape of the environment-friendly plastic is like a big red sausage, and the external plastic film is not melted, so that an operator can carry out plugging by hands, the operation is simple and efficient, the use amount of raw materials is well controlled, the non-curing waterproof coating becomes softer after being heated when meeting a heating zone, and the effect of better improving the effect of sealing and plugging water leakage of a settlement joint is achieved when the temperature is higher.
The leak stopping capsule is mainly used for settlement joints, namely settlement joints, between two different building structures, and due to the fact that the time materials of the buildings are different and the like, gaps can be formed between the two building structures, the gaps can be large or small and irregular, so that the leak stopping capsule is simple and flexible to operate.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the invention as defined by the appended claims. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
