Description

TECHNICAL FIELD

[0001] The present application relates to the field of building engineering, in particular to a convenient installation and removal protection device for a foundation pit support drainage pipe opening. BACKGROUND

[0002] The description in this section only provides background information related to the present disclosure and does not constitute prior art. In the construction of foundation pit, the support drainage pipe can guide the underground water out of the foundation pit, ensuring the drainage of the foundation pit while preventing the underground water from entering the inside of the foundation pit, thereby protecting the dryness and stability of the foundation pit. The pipe opening needs to be temporarily plugged during installation of the support drainage pipe to prevent concrete from entering the drainage pipe during subsequent concrete spraying. The existing plugging method usually uses a packaging bag to prevent the pipe opening, for example, using a woven bag of cement as a protective material, cutting the woven bag into the appropriate size, manually rolling it into a ball, and inserting it into the pipe opening. After the slope spraying and anchoring are completed, the woven bag is taken out and often discarded randomly, which may cause environmental pollution. Moreover, the woven bag needs to be taken out with the help of a ladder, which is labor-intensive. SUMMARY

[0003] Therefore, the present application provides a convenient installation and removal protection device for a foundation pit support drainage pipe opening, which can improve construction efficiency and be reused for environmental protection.

[0004] In order to achieve the above-mentioned purpose, the present application realizes the following technical solutions:

[0005] A convenient installation and removal protection device for a foundation pit support drainage pipe opening, characterized in that it comprises a drainage pipe and a protection piece sleeved on the drainage pipe; the protection piece comprises a shielding body for closing the pipe opening, a pulling component fixedly installed on the shielding body, and a fastening structure for fixing the shielding body to the outer wall of the drainage pipe.

[0006] The above-mentioned convenient installation and removal protection device for a foundation pit support drainage pipe opening can block the sprayed concrete with the shielding body, avoid plugging the drainage pipe, fix the shielding body on the drainage pipe with the fastening structure to avoid the shielding body from being sprayed off during concrete spraying, and conveniently remove the protection piece with the pulling component by an iron hook. Therefore, the device can improve construction efficiency and be reused for environmental protection.

[0007] In some embodiments, the shielding body is a cloth and is in the form of a cloth bag, and the fastening structure is an elastic drawstring installed in the cloth for tightening the cloth around the drainage pipe. The elastic drawstring can be a rubber rope and be threaded in the cloth. In this way, the cloth can protect the drawstring from corrosion by concrete, achieving the purpose of repeated use. Moreover, this structure is simple to manufacture and low in cost.

[0008] In some embodiments, the cloth is made of oxford cloth. The oxford cloth has the advantages of strong wear resistance, water resistance, and long service life.

[0009] In some embodiments, the shielding body is a cover, and the fastening structure is in the form of the inner wall of the cover tightly fitting the outer wall of the drain pipe. The cover can be made of the same plastic material as the drain pipe.

[0010] In some embodiments, the outer wall of the drain pipe is provided with an annular groove, the shielding body is a cover, and the fastening structure is a plurality of elastic anti-falling parts integrally connected to the cover and spaced apart in the circumferential direction on the cover. The elastic anti-falling parts are in the form of a V shape. When the elastic anti-falling parts move towards the drain pipe, the elastic anti-falling parts are radially pushed open by the drain pipe, so that the V-shaped tip of the elastic anti-falling parts can be clamped into the annular groove to form a clamping connection.

[0011] In some embodiments, the pulling component is selected from one of a metal ring, a cloth ring, and a metal hook.

[0012] In some embodiments, one end of the drain pipe is in the form of a spike, and the surface of the drain pipe near the spike end is provided with a plurality of drain holes.

[0013] In some embodiments, the outer part of the drain hole is further wrapped with a filter screen. The filter screen is mainly used to filter silt to prevent the drain hole from being blocked.

[0014] From the above technical solution, the present application has at least the following advantages and positive effects:

[0015] The convenient type protection device for the drain pipe opening of the foundation pit support can block the sprayed concrete, avoid blocking the drain pipe, fix the shielding body on the drain pipe through the fastening structure, avoid the shielding body from being sprayed off during the spraying of the concrete, and remove the protection member through the iron hook by the pulling component. Therefore, the device can improve the construction efficiency, is reusable, and is more environmentally friendly. BRIEF DESCRIPTION OF DRAWINGS

[0021] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be described in further detail below with reference to the drawings. The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0022] Reference Figures 1 to 2 The embodiment of the present application provides a convenient installation and removal protective device for a foundation pit support drain pipe opening, which comprises a drain pipe 1 and a protective piece 2 sleeved on the drain pipe 1; the protective piece 2 comprises a shielding body for closing the pipe opening, a pulling component fixedly installed on the shielding body, and a fastening structure for fixing the shielding body to the outer wall of the drain pipe 1.

[0023] The device can block the sprayed concrete by the shielding body, avoid clogging the drain pipe 1, and fix the shielding body on the drain pipe 1 by the fastening structure to avoid the shielding body from being sprayed off during spraying concrete.
