Description

Technical Field

[0001] The invention relates to the field of roadbed traffic safety protection facilities, and in particular to a permanent and temporary combined retaining wall structure that can be quickly assembled on site and a construction method. Background Art

[0002] Continuous heavy rainfall triggered landslides and river surges, causing the riverside roadbed retaining structures to be washed away and smashed, and the special protective structures set up on the inner slopes to be damaged. In the emergency road maintenance section, the existing solution is to re-install the retaining structure on site, which takes a long time to rescue and obviously cannot meet the requirements of rapid road maintenance and curbing the development of disasters. How to quickly realize the construction of retaining structures is an urgent problem that the engineering community needs to solve. Summary of the invention

[0003] In order to solve the above-mentioned problems, the present invention provides a permanent and temporary combined retaining wall structure and a construction method that can be quickly assembled on site. By adopting this solution, the retaining wall can be assembled on site through prefabricated components, which saves rescue time, can be quickly formed in the maintenance stage, reduces the damage to roads and pedestrians caused by landslides, and further stabilizes the slope.

[0004] The technical solution adopted by the present invention is: a permanent and temporary combined retaining wall structure that can be quickly assembled on site, comprising a frame unit close to the roadbed slope and a protective net arranged outside the frame unit;

[0005] The frame unit includes a plurality of transverse tubes and a plurality of support units;

[0006] The support unit includes a transverse tube and a column unit, there are two column units, and the support unit is arranged along the width direction of the roadbed;

[0007] The column unit comprises a vertical tube and a six-way pipe fitting, the two ends of the horizontal tube are necked, one end of the vertical tube is necked, the sizes of the vertical tube and the horizontal tube are matched with the six-way pipe fitting, and the necked end of the vertical tube is inserted into the six-way pipe fitting;

[0008] The same sides of the two column units are connected by a transverse tube, and the two ends of the transverse tube are respectively inserted into the six-way pipe fittings on the same side of the two column units;

[0009] The plurality of support units are arranged along the length direction of the roadbed; the same sides of two adjacent support units are connected by a transverse pipe, and the two ends of the transverse pipe are respectively inserted into the six-way pipe fittings on the same side of the two support units.

[0010] When this scheme is in operation, the vertical pipe is connected with the six-way pipe fitting, wherein the vertical pipe and the six-way pipe fitting have matching sizes, the horizontal pipe is inserted into the six-way pipe fitting to form a column unit, one column unit is set close to the slope, and the other column unit is set away from the slope, the two column units are connected by the horizontal pipe, and the six-way pipe fittings inserted into the two column units form a support unit, and there are multiple support units, which are set along the length of the roadbed, and the two adjacent support units are connected by the horizontal pipe to further form a frame unit, wherein the four horizontal ports of the six-way pipe fitting are used to connect the horizontal pipe, and the two vertical ports are used to connect the vertical pipe, so the frame unit can be infinitely lengthened in theory. The frame unit should be set at the roadbed slope, and a protective net should be set outside the frame unit. When a landslide occurs, the falling rocks will fall directly into the frame unit, and the protective net can block the falling rocks alone, reducing the damage to the road and pedestrians.

[0011] Furthermore, there are multiple frame units, and the multiple frame units are stacked in sequence along the height direction of the roadbed slope.

[0012] When this scheme is put into operation, when a landslide or slope damage is serious, another frame unit can be stacked on top of the frame unit in turn according to the on-site conditions, and the two adjacent frame units in the height direction are connected by six-way pipe fittings.

[0013] Furthermore, it also includes a plurality of grouting pipes, which are inserted into the foundation through the vertical pipes in the frame unit, and the grouting pipes are located inside the vertical pipes.

[0014] In the specific operation of this scheme, since the interior of the vertical pipe and the six-way pipe fittings are hollow, a grouting pipe can be directly driven into the vertical pipe, driven into the foundation 2 to 3 meters, and grouting is performed to improve the stability of the frame unit;

[0015] Furthermore, the grouting pipe is inserted into the slope through a transverse pipe in the frame unit, and the grouting pipe is located inside the transverse pipe.

[0016] When this scheme is put into practice, when the landslide is more serious, a grouting pipe can be driven into the inside of the horizontal pipe in the frame unit, and then driven into the slope to grout the slope and reinforce the slope to prevent further development of collapse.

[0017] Furthermore, there are multiple vertical pipes in the column unit, and the multiple vertical pipes are stacked in sequence.

[0018] When this solution is put into operation, multiple vertical pipes can be arranged in the column unit, and each vertical pipe is connected in sequence. After reaching a certain height, the six-way pipe fittings are connected to save the cost of using horizontal pipes.

[0019] Furthermore, in order to improve the stability of the frame unit, it is configured as follows: the transverse pipe, six-way pipe fitting, vertical pipe and protective net are all made of steel material.

[0020] Furthermore, a permanent and temporary combined retaining wall structure and construction method for rapid on-site assembly includes the following steps:

[0021] S1: Factory prefabricated horizontal pipes, six-way pipe fittings, grouting pipes, vertical pipes and protective nets;

[0022] S2: Quickly assemble the frame units on the roadbed slope and increase the length of the frame units according to the damage of the roadbed slope on site.

[0023] S3: Install a protective net on the outside of the frame unit and fill the inside of the frame unit with gravel from the site;

[0024] S4: Insert grouting pipes into the vertical pipes in the frame unit, and insert the grouting pipes into the foundation for grouting.

[0025] S5: After grouting is completed and the road foundation is secured, the frame unit is externally formworked and concrete is poured to form a permanent retaining wall support.

[0026] Furthermore, S2 also includes the following sub-steps: when the roadbed slope at the site is severely damaged, the frame units can be stacked upwards in sequence according to the damage situation.

[0027] Furthermore, the S4 also includes the following sub-steps: when the slope collapses seriously, inserting a grouting pipe into the interior of the transverse pipe in the frame unit, and inserting the grouting pipe into the slope for grouting.

[0028] When this scheme is put into operation, a plurality of parts required in this scheme are prefabricated first, and then the parts are directly sent to the landslide section, and the frame unit can be directly assembled on site. In the existing scheme, it takes a lot of time to arrive at the landslide site and then start to make the rescue device, while this scheme can directly achieve the effect of rapid rescue, save rescue time, and enable the road to be quickly opened; when assembling the frame unit, the length of the frame unit should be reasonably lengthened according to the actual damage situation on site, and the frame unit can also be repeatedly stacked in the height direction. The structure of this device is simple and can be quickly assembled to achieve the effect of quickly opening the section; after the frame unit is assembled, a protective net is fixedly installed on the side of the frame unit to make the landslide The fallen gravel and the like directly enter the frame unit and will not fall out of the frame unit. In previous landslides, the fallen gravel and the like on site can be filled in the frame unit for storage. Then a grouting pipe is inserted into the vertical pipe in the frame unit and inserted 2-3m downward into the foundation for grouting to further stabilize the frame unit. If the slope collapses severely, a grouting pipe is also inserted into the inside of the horizontal pipe in the frame unit and the grouting pipe is inserted into the slope for grouting to reinforce the slope and prevent further collapse. Finally, after the grouting is completed and the roadbed is secured, the outside of the frame unit is supported by formwork and concrete is poured to form a permanent retaining wall support, which continuously stabilizes the mountain while providing safety for a long time.

[0029] The present invention has the following beneficial effects:

[0030] This solution provides a permanent and temporary combined retaining wall structure and construction method that can be quickly assembled on site. With this solution, the retaining wall can be assembled on site through prefabricated components, which saves rescue time and can be quickly formed during the maintenance phase, reducing the damage to roads and pedestrians caused by landslides and further stabilizing the slopes. The temporary frame unit can be supported by external formwork and poured with concrete to form a permanent retaining wall support, providing safety for a long time.
