Abstract
Description
Technical Field
[0001] The invention relates to the technical field of water leakage treatment of deformation joints of cast-in-place underground comprehensive pipe corridors, and in particular to a drainage construction method for deformation joints of cast-in-place underground comprehensive pipe corridors. Background Art
[0002] The pipe gallery is the artery of the city's underground facilities. Water leakage has always been a common quality problem that plagues underground pipe gallery projects. As a "century-old project", effective waterproofing has become a top priority for underground pipe gallery. The pipe gallery is basically a horizontal full-length structure buried underground. It is generally equipped with many nodes and structural joints. Even if rubber waterstops or steel waterstops are installed at the structural joints and nodes, with the combined influence of various factors such as the creep of underground silt, the dynamic load of a large number of vehicles on the surface, the lateral pressure generated by surrounding buildings, and the uneven settlement of the structure, the expansion joints of the pipe gallery will cause different degrees of dislocation, floating, and cracking of the waterstops, resulting in leakage in the expansion joints of the pipe gallery, which brings safety hazards to various pipes and pipelines inside. Generally, underground comprehensive pipe galleries have a certain drainage capacity, but the gap is too large, a large amount of water flows in, and the underground comprehensive pipe gallery cannot timely discharge the water that penetrates into the underground comprehensive pipe gallery from the cracks. When the impurity cracks of the rubber waterstop or steel waterstop are generated, they will also crack, and the cracks cannot be optimally blocked. Moreover, the bottom crack blocking is relatively more troublesome. Summary of the invention

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0032] like Figure 1-7 As shown, the present invention proposes a drainage construction method for deformation joints of cast-in-place underground comprehensive pipe gallery, and the specific steps are as follows:
[0033] S1: Deeply dig a deep trench of the inverted type, lay a cement foundation 8 at the bottom of the deep trench of the inverted type, and arrange bottom deformation joint leakage prevention component grooves at equal intervals on the cement foundation 8, install bottom deformation joint leakage prevention components in each bottom deformation joint leakage prevention component groove, and arrange four L-shaped pipes 10 extending to the edge of the cement foundation 8 and buried in the cement foundation 8 at the four corners of each bottom deformation joint leakage prevention component groove, build a cast-in-place underground comprehensive pipe gallery steel frame and outer baffle on the cement foundation 8, and both ends of each segment of the cast-in-place underground comprehensive pipe gallery 1 are located in the middle of the corresponding bottom deformation joint leakage prevention component, and each cast-in-place underground comprehensive pipe gallery 1 is provided with a leakage hole docking with the corresponding L-shaped pipe 10 when cast-in-place, and the cast-in-place underground comprehensive pipe gallery 1 is spliced section by section;
[0034] The cement foundation 8 has a certain ability to prevent bottom deformation, has a thickness of 50-80cm, and is a reinforced cement layer. A deformation joint leak-proof component groove is set at each distance, which is used to install the bottom deformation joint leak-proof component after solidification. When the bottom deformation joint leak-proof component sinks at the docking position of the cast-in-place underground comprehensive pipe gallery, it has a certain blocking effect, and the water seepage strength is greatly reduced. When there is water accumulation in the cast-in-place underground comprehensive pipe gallery, it will flow into the L-shaped pipe 10 from the leakage hole. Since the bottom of the cast-in-place underground comprehensive pipe gallery and the bottom of the square drainage pipe 5 are different in terrain (generally at least 50cm or more), water will automatically flow into the square drainage pipe 5. After accumulating a certain water level, the square drainage pipe 5 will automatically drain and will not flow back into the cast-in-place underground comprehensive pipe gallery;
[0035] S2: A side deformation joint anti-leakage component is attached to the two side walls of the splicing position of the cast-in-place underground integrated pipe gallery 1, and two pipe grooves are provided on the cement foundation 8 below the outer side wall of the side deformation joint anti-leakage component. Square drainage pipes 5 are plugged in the two pipe grooves, and the inner and outer walls of the square drainage pipes 5 tightly clamp the outer side wall of the side deformation joint anti-leakage component;
[0036] The square drainage pipe 5 is inserted into the cement foundation 8 by about 35-60 cm to stabilize the square drainage pipe 5, form a terrain difference with the cast-in-place underground integrated pipe gallery 1, and squeeze the side deformation joint anti-leakage component to make it fit on the outer wall of the cast-in-place underground integrated pipe gallery 1;
[0037] S3: First, a steel frame is set up inside the outer wall of the square drainage pipe 5 and the side wall of the inverted deep ditch, and cement slurry is poured inside and compacted so that the square drainage pipe 5 is tightly squeezed against the side deformation joint leakage prevention component. After the cement solidifies, a steel frame is lowered between the adjacent side deformation joint leakage prevention components on the same side of the cast-in-place underground comprehensive pipe gallery 1, and then cement is filled to solidify; the sides and gaps are filled with steel bars and cement to make them more stable.
[0038] S4: After step S3 is completed, a layer of cement is filled in the inverted deep groove to make the inverted deep groove level, and then a steel grid is laid on the cement plane, and finally, cement is filled to the top of the inverted deep groove;
[0039] S5: A drain pipe is provided on the outer side wall of the square drain pipe 5, and the drain pipe is connected to the urban drainage ditch. The drain pipe is provided one at a certain distance according to the needs, and a water pump is provided in the drain pipe; once a certain water level is reached, water is pumped out.
[0040] Wherein, the bottom deformation joint leakage prevention component includes a rubber sleeve block 2 and a bottom waterproof rubber pad 3, the length of the rubber sleeve block 2 is equal to the width of the cast-in-place underground integrated pipe gallery 1, the rubber sleeve block 2 is provided with a rubber groove, the inner wall of the rubber groove is provided with an opening and the opening height is 4 / 5 of the depth of the rubber groove, the thickness of the bottom waterproof rubber pad 3 is equal to the opening height, the bottom of both ends of the bottom waterproof rubber pad 3 is provided with an anti-slip convex strip 31 integrated therewith, the sum of the thickness of the bottom waterproof rubber pad 3 and the thickness of the anti-slip convex strip 31 is equal to the depth of the rubber groove, the two rubber sleeve blocks 2 in the same bottom deformation joint leakage prevention component groove are arranged at both ends of the groove and a 5-10cm gap is left between the two, and the left and right halves of the bottom waterproof rubber pad 3 are buckled in the two rubber grooves respectively;
[0041] Since the bottom waterproof rubber pad 3 has movable pulling, when sinking, the rubber sleeve block 2 will go down together, but the bottom waterproof rubber pad 3 will be pulled out. Generally, the lower layer of about 30 cm can be blocked. The bottom waterproof rubber pad 3 will be attached to the gap, which greatly reduces the gap opening and water seepage. The anti-slip convex strip 31 prevents the bottom waterproof rubber pad 3 from being pulled out on one side while the other side remains still.
[0042] The side deformation joint leakage prevention component includes abutment blocks 4 and bonding plates 41, wherein the abutment blocks 4 include square abutment blocks and plug-in blocks arranged at the bottom, wherein the length of the plug-in blocks is equal to the length of the bottom deformation joint leakage prevention component groove and the height is equal to the depth of the groove, the front side of the abutment block 4 is provided with an inverted convex opening and a cavity is provided inside thereof, the cavity inside the abutment block 4 is provided with four limiting slide bars 42 at four corner positions, the shape of the bonding plate 41 matches the convex opening, the bonding plate 41 is provided with sliders 412 movably sleeved on the limiting slide bars 42 at four corner positions, a layer of bonding rubber skin 411 is fixed on the front side wall of the bonding plate 41, and a water inlet square hole 40 is respectively arranged on the rear side wall of the abutment block 4 near the upper and lower ends, and each of the two water inlet square holes 40 on the rear side wall of the abutment block 4 is provided with a connecting pipe at the side wall position where the square drain pipe 5 is bonded, and the connecting pipe is just inserted into the water inlet square hole.
[0043] At the beginning, when water accumulates at the joint of the rubber skin 411 on the outer wall of the laminated plate 41, the laminated plate 41 (including water squeezed in the square drain pipe 5) will be squeezed when water accumulates at the side deformation joint anti-leakage assembly. Even if there are cracks in the cast-in-place underground integrated pipe gallery 1, the laminated plate 41 will not crack and will still block the cracks. The water seepage from the cracks in the side wall is greatly reduced, and the water seepage into the cast-in-place underground integrated pipe gallery 1 is reduced, and the drainage of the cast-in-place underground integrated pipe gallery 1 will not be too difficult.
[0044] The rubber sleeve block 2 has a plurality of vertical connection columns inserted at the top of the rubber groove side wall. When the cast-in-place underground integrated pipe gallery 1 is cast, these vertical connection columns will be inserted into the bottom wall frame of the cast-in-place underground integrated pipe gallery 1 and will be connected to the bottom wall of the cast-in-place underground integrated pipe gallery 1 during casting;
[0045] At the same time, when constructing the frame of the cast-in-place underground integrated pipe gallery 1, a layer of plastic film is first laid on the rubber sleeve block 2 and the bottom waterproof rubber pad 3, and the vertical connecting column penetrates the plastic film.
[0046] The rubber sleeve 2 is integrated with the cast-in-place underground integrated pipe gallery 1, and when sinking, it sinks together with the cast-in-place underground integrated pipe gallery 1, but the bottom waterproof rubber pad 3 does not sink, but is pulled out. The phenomenon that the plastic film prevents the casting and the bottom waterproof rubber pad 3 from being bonded as one occurs.
[0047] The height of the rubber sleeve 2 is 30-40 cm, the thickness of the bottom waterproof rubber pad 3 is 15-20 cm, the thickness of the anti-slip convex strip 31 is 5-8 cm, and the length of the bottom waterproof rubber pad 3 is 80-100 cm. Cracks up to 30 cm can be sealed.
[0048] The square drain pipe 5 is a prefabricated reinforced concrete pipe, the wall thickness of the square drain pipe 5 is 15-25 cm, the inner width of the square drain pipe 5 is 50-70 cm, and the middle position of the square drain pipe 5 is higher than the bottom of the cast-in-place underground integrated pipe gallery 1 and is at the same level. The wall thickness of the square drain pipe 5 is sufficient for drainage, and if it is actually needed to be thicker, the thickness can be appropriately increased. The size is not limited to the above.
[0049] A float 6 is provided in the middle of the square drain pipe 5, and the float 6 is installed at the bottom end of the top rod. The top end of the top rod movably penetrates the top wall of the square drain pipe 5 and a pressure sensing device 61 is provided at the top of the top rod, and the pressure sensing device 61 is installed on the top outer wall of the square drain pipe 5. The pressure sensing device 61 is similar to a weight scale (electronic), and when the top rod reaches a certain force, the water pump is started.
[0050] The inner cavity depth of the abutment block 4 is equal to the total thickness of the laminating plate 41 and the laminating rubber skin 411. When there is no water pressure, it is fitted, and when there is a crack at the back, water seeps in, and the laminating plate 41 can be squeezed by water to make it further fitted.
[0051] The outer wall of the square drain pipe 5 is evenly provided with small water seepage holes, and the diameter of the water seepage holes is 1-2 cm. After the square drain pipe 5 is installed in the cement foundation 8, a layer of easily degradable plastic film is attached to the outer wall of the square drain pipe 5, and then a steel frame is set up between the outer wall of the square drain pipe 5 and the side wall of the inverted deep ditch, and cement slurry is poured inside it.
[0052] When there is water seepage outside the square drainage pipe 5, any water that seeps into the square drainage pipe 5 will not flow to the outer wall of the cast-in-place underground integrated pipe gallery 1. Even if there is water seepage, the amount is small. After the pouring is completed, the degradable plastic film will degrade over a period of time, and any water that seeps can penetrate. During pouring, cement is prevented from blocking the water seepage holes, and partial blockage does not affect the water seepage.
[0053] When pouring one section of the cast-in-place underground integrated pipe gallery 1, a circle of extended steel bars should be reserved at the butt end. When pouring the next section and building the steel bar frame, the extended steel bars 1 will be connected to the newly built steel bar frame.
[0054] To facilitate stable connection, the exposed length of the extended steel bars shall not exceed 1 / 3 of the length of the cast-in-place underground integrated pipeline corridor 1.
[0055] The height of the bonding board 41 is not less than 4 / 5 of the height of the cast-in-place underground integrated pipe gallery 1, and the width of the bonding board 41 is not less than 1 / 2 of the height of the cast-in-place underground integrated pipe gallery 1. It is suitable for sealing cracks of about 30 cm or less.
[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
