Technical Field

[0001] The utility model relates to a protective device for pipe gallery foundation pit construction. Background Art

[0002] During the construction of an underground pipeline corridor, it is first necessary to excavate a foundation pit on the ground, and then hoist the pipeline corridor prefabricated components into the foundation pit for installation. After the installation is completed, auxiliary materials are filled between the foundation pit and the pipeline corridor prefabricated components, and then the foundation pit is filled and leveled.

[0003] In actual construction, we found that after the prefabricated pipe gallery parts were hoisted into the foundation pit, the outer wall of the prefabricated pipe gallery parts and the inner wall of the foundation pit could not maintain sufficient spacing, resulting in insufficient filling thickness of the auxiliary materials when filling them later.

[0004] Based on the above problems, we designed a pipeline corridor foundation pit construction protection device that can protect the inner wall of the foundation pit to prevent the foundation pit from collapsing, and at the same time can limit the falling position of the pipeline corridor prefabricated parts.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] See Figure 1 The protective device for the construction of a pipe gallery foundation pit shown in the figure includes a guard plate 1, the front end face of the guard plate 1 is a plane 101, and the plane 101 is where the pipe gallery prefabricated parts are to be installed. The lower position of the rear end face of the guard plate 1 is processed to form a slope 102. The thickness of the guard plate 1 gradually decreases at the slope 102, and a protruding part 2 is provided near the upper position of the plane 101.

[0029] The guard plate 1 is made of steel and is formed by casting. The vertical height of the guard plate 1 is greater than the depth of the excavated foundation pit. The lower part of the guard plate 1 is inserted into the bottom of the foundation pit, and the insertion depth is not less than 60 cm. The vertical height of the guard plate 1 is greater than 240 cm. In this embodiment, the height of the guard plate 1 is 300 cm, the width is 60 cm, and the thickness is 12 cm.

[0030] After the guard plate 1 is inserted, the pipe gallery prefabricated component is hoisted into the foundation pit, and the positioning of the pipe gallery prefabricated component is completed through the protruding parts 2 on both sides, so that a sufficient distance is maintained between the outer side surface of the pipe gallery prefabricated component and the inner wall of the foundation pit to facilitate the later construction needs.

[0031] See Figure 1 As shown, a slot 103 is provided at the upper end of the guard plate 1 , and an anchor hole 104 is provided on the surface of the protruding portion 2 so as to pass through the slot 103 vertically.

[0032] The slots 103 and the anchor holes 104 are used to lift the guard plate 1 with the help of lifting equipment.

[0033] See Figure 2 and Figure 3 As shown, card slots 105 are provided on the left and right sides of the guard plate 1, and the lower ends of the card slots 105 are closed. Between adjacent guard plates 1, there are plug-in plates 3 fitted through the card slots 105. A cover plate 31 is provided on the top of the plug-in plate 3. The two adjacent cover plates 31 are combined to close the slot 103.

[0034] In the above technical solution, by inserting the inserting plate 3, two adjacent guard plates 1 can be aligned, and multiple guard plates 1 on the same side can form a stable overall structure.

[0035] The cover plate 31 can cover the slot 103 to reduce the entry of foreign matter.

[0036] See Figure 3 As shown, two hanging plates 4 are provided at the front and rear of the top of the cover plate 31 , and hanging holes 41 are processed on the plate surfaces of the hanging plates 4 .

[0037] The provision of the hoisting plate 4 is to facilitate the lifting of the plugboard 3 by means of a lifting device.

[0038] See Figures 1 to 5 As shown, connection holes 311 are processed on the top of the cover plate 31 near the four corners, and a heightening plate 5 is provided on the top of the cover plate 31. The heightening plate 5 is located between the two lifting plates 4. Ear plates 51 are provided at the front and rear end surfaces of the heightening plate 5. Screws 52 are fitted between the ear plates 51 and the connection holes 311, and two adjacent heightening plates 5 are fitted together.

[0039] The bottom of the foundation pit needs to be level, but the ground is undulating, so some low-lying areas need to be raised to prevent ground water from flowing into the foundation pit. Therefore, the above technical solution uses a heightening plate 5 to increase the height of the barrier, especially for low-lying areas.

[0040] See Figure 1As shown, the upper end of the protruding portion 2 is processed to form an assembly slope 201.

[0041] The assembly slope 201 is used to guide the prefabricated pipe gallery components when they are hoisted in, so that the prefabricated pipe gallery components can be smoothly placed in the correct position.

[0042] The protruding portion 2 and the guard plate 1 are an integrally cast structure.

[0043] See Figure 2 As shown, a guide portion 3331 is provided at the bottom of the inserting plate 3, and the width and thickness of the guide portion 3331 are gradually reduced downward.

[0044] The guide portion 3331 facilitates the transfer of the plugboard 3 .
