Description

TECHNICAL FIELD

[0001] The present application relates to the field of construction engineering, in particular to a new concrete construction method. BACKGROUND

[0002] Generally, the slope protection of the mountain slope is mostly to lay cement concrete on the slope surface to strengthen the slope surface and prevent rainwater erosion. Although such concrete slope surface can strengthen the slope surface and prevent rainwater erosion, the slope surface is a bare artificial surface, which destroys the ecology of nature.

[0003] Chinese patent application No. 200510093007.3 discloses a greening concrete construction method, which comprises the following steps: a) slope leveling; b) laying a three-dimensional net on the slope; c) reinforcing the three-dimensional net with steel bars and anchor nails; d) laying concrete on the slope with the laid three-dimensional net; e) spraying mixed plant growth substrate on the concrete; and f) plant growth maintenance. The method can grow green grass on the reinforced concrete slope with strong structure, so as to have the effects of greening, beautifying the landscape, and water and soil conservation.

[0004] However, since the three-dimensional net is fixed on the slope and the concrete is laid on the slope, the soil on the slope is covered under the concrete. The soil layer on the upper side of the concrete is thin by spraying the mixed plant growth substrate on the concrete, the planted vegetation cannot form a good fixing effect due to the shallow root, and the vegetation is easy to fall off once the heavy rain washes. In addition, the long-term planting of the vegetation on the concrete is easy to cause the corrosion of the concrete, reduce the strength of the concrete, and the vegetation needs to be maintained regularly, so the convenience is relatively poor. SUMMARY

[0005] Therefore, in view of the above problems, the present application provides a new concrete construction method suitable for greening slope protection, and having good slope protection firmness and stable vegetation planting.

[0006] To achieve the above object, the present application adopts the following technical scheme:

[0007] A new concrete construction method, comprising the following steps:

[0008] 1) leveling the slope surface to be constructed, removing the protruding stones and sundries on the slope surface, and compacting the slope surface after watering;

[0009] 2) Detect the slope gradient, slope area, and slope flatness, then generate a slope plan based on the detection data, and draw a design diagram of the distribution of the slope protection cement beams on the plan. The slope protection cement beams include several first slope protection beams and several second slope protection beams arranged in parallel. Each first slope protection beam and second slope protection beam is intersected, so that the first slope protection beams and second slope protection beams form multiple openings with a rhomboid structure, and the intersection of the first slope protection beams and second slope protection beams forms a connection area.

[0010] 3) Implement the design standards of the slope protection cement beam distribution design drawing, mark the distribution location of the slope protection cement beams in advance on the slope with lime powder, and dig cylindrical pits with a depth of 60cm to 120cm at the connection area.

[0011] 4) The boring device is inserted into the cylindrical pit to bore a stepped groove into the lower side wall of the cylindrical pit;

[0012] 5) The steel bars are woven into a cylindrical structure and embedded into the boring device. By impacting the boring device, the lower part of the steel bars bends and extends into the stepped groove.

[0013] 6) Lay a first three-dimensional mesh layer on the compacted slope. The first three-dimensional mesh layer has a plurality of first mesh holes distributed in a matrix, and through holes are cut out on the first three-dimensional mesh layer at the locations corresponding to the cylindrical pits.

[0014] 7) Weld and fix the first three-dimensional mesh layer to each steel column;

[0015] 8) Based on the distribution location of the slope protection cement beams marked in step 3, pre-embed anchors in the soil around them and at the first mesh, and install templates at the marked slope protection cement beams to form a casting cavity. The templates are connected to the anchors through connecting components.

[0016] 9) Weave a steel mesh layer inside the mold cavity;

[0017] 10) Select raw materials, prepare concrete, and develop a transportation plan based on the concrete pouring time and distance;

[0018] 11) Transport the concrete to the slope to be constructed and stir it for 6 min to 8 min before pouring to ensure that the concrete is evenly mixed. Then pour the concrete into the mold cavity in layers and compact it with an immersion vibrator. The vibration time at each position is until the concrete no longer settles significantly. Water curing is carried out within 15 h to 20 h after the concrete is poured, and the curing is carried out continuously for 12 days.

[0019] Furthermore, the first slope protection beam is inclined with an inclination of 20° to 45°, and the second slope protection beam is inclined with an inclination angle of 90° to 160°.

[0020] Furthermore, the first slope protection beam is inclined at an angle of 30°, and the second slope protection beam is inclined at an angle of 90°.

[0021] Furthermore, the steel mesh layer includes longitudinal steel bars distributed along the length direction of the first or second slope protection beam, transverse steel bars distributed along the width direction of the first or second slope protection beam, and a second three-dimensional mesh layer. The longitudinal steel bars include steel bar units that are continuously welded together in sequence. The steel bar units in the width direction are staggered. Each steel bar unit includes a first part, a second part, and a third part connecting the first part and the second part. The included angle between the first part and the third part is 90° to 120°, and the included angle between the second part and the third part is 90° to 120°. Two adjacent steel bar units in the length direction are welded and fixed to the second part of the other steel bar unit through the first part of one steel bar unit. Two adjacent steel bar units in the vertical direction are welded and fixed to the second part of the other steel bar unit through the connection between the first part and the third part of one steel bar unit. The second three-dimensional mesh layer is distributed on the upper layer of the mold cavity and is fixedly connected to the second part.

[0022] Furthermore, the boring device in step 4 above works as follows: by hammering the upper part of the boring device, the digging claw at the lower part of the boring device extends outward along the radial direction of the cylindrical pit, so that the lower side wall of the cylindrical pit is bored out with a stepped groove. After hammering 5 to 8 times, the boring device is rotated 5° to 8°, and the digging claw brings the bored soil into the boring device. The soil is then taken out of the cylindrical pit by pulling out the boring device.

[0023] Furthermore, the reinforcing bar column includes an inner ring and an outer ring arranged in concentric circles. The inner ring includes multiple first reinforcing bars arranged side by side along the axial direction of the reinforcing bar column and a first ring for fixing the first reinforcing bars. The outer ring includes multiple second reinforcing bars arranged side by side along the axial direction of the reinforcing bar column and a second ring for fixing the second reinforcing bars. The first and second reinforcing bars are staggered, such that the lower parts of both the first and second reinforcing bars bend and extend into the stepped groove, and their free ends are embedded in the soil. The bent first reinforcing bars are distributed on the upper side of the bent second reinforcing bars.

[0024] Furthermore, the concrete composition includes 450-600 parts cement, 20-40 parts mineral powder, 80-90 parts fly ash, 15-25 parts polycarboxylate admixture, 800-1000 parts aggregate, and 700-900 parts sand.

[0025] Furthermore, in step 11 above, each layer of the concrete is 25cm to 35cm thick, and the second layer of concrete is poured before the first layer of concrete has initially solidified. The free fall height of the concrete during pouring does not exceed 0.5m.

[0026] By adopting the aforementioned technical solution, the beneficial effects of this invention are as follows: This novel concrete construction method, through the preparation and compaction of the slope surface, makes the slope surface flat, facilitating the mapping of the slope plan, and thus aiding in the creation of a design drawing for the distribution of the slope protection cement beams. Furthermore, the method involves the intersecting distribution of several inclined first slope protection beams and several inclined second slope protection beams, forming multiple rhomboid openings that facilitate vegetation planting. This allows the roots of the vegetation to take hold in the slope soil, working in conjunction with the slope protection cement beams to stabilize the slope soil. A cylindrical pit is created at the connection area between the first and second slope protection beams, and a stepped groove is bored into the lower part of the cylindrical pit, with corresponding steel reinforcement columns embedded therein. A boring device is used to assist in boring the stepped grooves, and the lower part of the steel reinforcement columns extends towards the stepped grooves, thereby improving construction efficiency. This allows the poured cement slurry to combine with the steel reinforcement columns and embed into the cylindrical pits and... Within the stepped groove, the axial movement of the cylindrical column is prevented, improving connection strength. It then forms a three-dimensional slope protection net structure with the first and second slope protection beams, and is fixed to the first three-dimensional net layer to achieve slope interception. This improves slope protection without affecting vegetation planting. Pre-embedded anchors and templates facilitate template adjustment, improving installation convenience and efficiency. The woven steel mesh layer within the mold cavity prevents cement slurry from accumulating during pouring. The layered pouring method enhances the uniformity of the cement slurry poured on the slope, significantly improving the strength of the formed first and second slope protection beams. This increases the forming strength of the cement beams, resulting in better slope protection. Larger openings are provided for vegetation planting, allowing the roots of planted vegetation to take root effectively, improving slope stability and vegetation planting stability.

[0037] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0038] The embodiments of the present invention are as follows:

[0039] refer to Figures 1 to 4 As shown, a novel concrete construction method includes the following steps:

[0040] 1) Level the slope surface to be constructed, remove any protruding stones and debris, and then compact the surface after watering it.

[0041] 2) Detect the slope gradient, slope area, and slope flatness, then generate a slope plan based on the detection data, and draw a design diagram of the slope protection cement beam distribution on the plan. The slope protection cement beam includes several first slope protection beams 1 and several second slope protection beams 2 arranged in parallel. The first slope protection beams 1 are inclined with an inclination of 20° to 45°, preferably 30°. The second slope protection beams 2 are inclined with an inclination angle of 90° to 160°, preferably 95°. The first slope protection beams 1 and the second slope protection beams 2 are intersected, so that the first slope protection beams 1 and the second slope protection beams 2 form multiple rhomboid openings 3, and the intersection of the first slope protection beams 1 and the second slope protection beams 2 forms a connection area 4.

[0042] 3) The design standard of the slope protection cement beam distribution design drawing shall be implemented.

[0043] 4) The boring device 7 is embedded into the cylindrical pit 5. The upper part of the boring device 7 is hammered to drive the digging claw 791 at the bottom of the boring device to extend outward along the radial direction of the cylindrical pit 5, so that the lower side wall of the cylindrical pit 5 is bored out with a stepped groove 6. After hammering 6 times, the boring device is rotated 8°. The digging claw 791 brings the bored soil into the boring device 7.

[0045] 6) Lay a first three-dimensional mesh layer 9 on the compacted slope. The first three-dimensional mesh layer 9 has a plurality of first mesh holes distributed in a matrix, and through holes are cut out on the first three-dimensional mesh layer 9 at the locations corresponding to the cylindrical pits 5.

[0046] 7) Weld and fix the first three-dimensional mesh layer 9 to each of the steel reinforcement columns 8;

[0047] 8) Based on the distribution location of the slope protection cement beams marked in step 3, pre-embed anchors 10 in the soil around them and at the first mesh, and install templates 11 at the marked slope protection cement beams to form a casting mold cavity. The templates 11 are connected to the anchors 10 through the connecting components 12.

[0048] 9) A steel mesh layer 13 is woven within the mold cavity. The steel mesh layer 13 includes longitudinal steel bars 131 distributed along the length direction of the first slope protection beam 1 or the second slope protection beam 2, transverse steel bars 132 distributed along the width direction of the first slope protection beam 1 or the second slope protection beam 2, and a second three-dimensional mesh layer 133. The longitudinal steel bars 131 include steel bar units 100 that are continuously welded together in sequence. The steel bar units in the width direction are staggered. Each steel bar unit 100 includes a first part 101, a second part 102, and a third part 103 connecting the first part 101 and the second part 102. The included angle between the first part 101 and the third part 103 is 90° to 120°. Preferably, the angle is 120°. The included angle between the second part 102 and the third part 103 is 90° to 120°, preferably 120°. Two adjacent steel bar units 100 in the length direction are welded and fixed to the second part 102 of the other steel bar unit 100 through the first part 101 of one steel bar unit 100. Two adjacent steel bar units 100 in the vertical direction are welded and fixed to the second part 102 and the third part 103 of the other steel bar unit 100 through the connection between the first part 101 and the third part 103 of one steel bar unit 100. The second three-dimensional mesh layer 133 is distributed on the upper layer of the mold cavity and is fixedly connected to the second part 102.

[0049] 10) Select raw materials, prepare concrete, and formulate a transportation plan based on the concrete pouring time and distance. The concrete composition includes 500 parts cement, 25 parts mineral powder, 87 parts fly ash, 17 parts polycarboxylate admixture, 1000 parts gravel, and 800 parts sand.

[0050] 11) Transport the concrete to the slope to be constructed and stir it for 6 minutes before pouring to ensure that the concrete is evenly mixed. Then pour the concrete into the mold cavity in layers, each layer being 30cm. The second layer of concrete should be poured before the first layer of concrete has initially set. The free fall height of the concrete during pouring should not exceed 0.5m. Use an immersion vibrator to compact it. The vibration time at each location should be until the concrete no longer settles significantly. Water curing should be carried out within 20 hours after the concrete is poured, and continuous curing should be carried out for 12 days.

[0051] This novel concrete construction method, by leveling and compacting the slope surface, makes the slope flat, facilitating the mapping of the slope plan and, consequently, the creation of a design plan for the distribution of the retaining concrete beams. Several inclined first retaining beams 1 and several inclined second retaining beams 2 are interspersed, forming multiple rhomboid openings 3 to facilitate vegetation planting. This allows the roots of the vegetation to take hold in the slope soil, working in conjunction with the retaining concrete beams to stabilize the soil. Cylindrical pits 5 are created at the connection area 4 between the first and second retaining beams 1 and 2, and stepped grooves 6 are bored into the lower part of the cylindrical pits 5, with corresponding steel reinforcement columns 8 embedded therein. A boring device 7 is used to assist in boring the stepped grooves 6, and the lower part of the steel reinforcement columns 8 extends into the stepped grooves 6, thereby improving construction efficiency. The poured cement slurry and steel reinforcement columns 8 are integrated into the cylindrical pits 5 and stepped grooves 6, preventing the cylindrical... The pulling of column 5 along its axis increases the connection strength, forming a three-dimensional slope protection net structure with the first slope protection beam 1 and the second slope protection beam 2. It is then fixed to the first three-dimensional net layer 9 to achieve the interception effect on the slope. This improves the slope protection effect without affecting vegetation planting. Anchor nails 10 are pre-embedded and fixed to the template 11, facilitating the adjustment of the template 11 and improving the installation convenience and efficiency of the template 11. The setting of the woven steel mesh layer 13 in the mold cavity prevents the accumulation of cement slurry during the pouring process. The layered pouring method improves the uniformity of the cement slurry poured on the slope, thereby greatly ensuring the strength of the formed first slope protection beam 1 and the second slope protection beam 2. This improves the forming strength of the slope protection cement beam, resulting in a good slope protection effect. It also allows for larger openings for vegetation planting, and the roots of the planted vegetation can take root well in the soil, improving the stability of the slope protection and the stability of the vegetation planting.

[0052] Furthermore, the first slope protection beam 1 is inclined at an angle of 30°, and the second slope protection beam 2 is inclined at an angle of 95°. The first slope protection beam 1 and the second slope protection beam 2 are intersecting, resulting in the diagonals of the openings 3 of the formed rhomboid structure being inclined. This ensures good structural stability of the cement slope protection beams and facilitates soil fixation in both the longitudinal and transverse directions of the slope, improving the slope protection effect. The steel mesh layer 13, formed by longitudinal steel bars 131, transverse steel bars 132, and a second three-dimensional mesh layer 133, is suitable for slope casting, significantly increasing the strength of the cast-in-place first slope protection beam 1 and second slope protection beam 2. Specifically, the steel reinforcement unit 100 on the longitudinal steel reinforcement 131 is integrally connected by the first part 101, the second part 102 and the third part 103. Two adjacent steel reinforcement units 100 in the vertical direction are welded and fixed to the second part 102 and the third part 103 of the other steel reinforcement unit 100 through the connection between the first part 101 and the third part 103 of one steel reinforcement unit 100. The second three-dimensional mesh layer 133 is distributed on the upper layer of the mold cavity and is fixedly connected to the second part 102, so that it is suitable for installation construction on sloped surfaces with inclination. The third part 103 can be used to prevent the cement slurry from falling during pouring, thereby improving the uniformity of the cement slurry.

[0053] In this embodiment, reference Figures 5 to 9As shown, the boring device 7 includes a tubular outer tube 71, multiple support columns 72, multiple bases 73, a guide rod 74, a guide sleeve 75, a top block 76, a pressure block 77, a spring 78, and a boring assembly 79. Each base 73 has a petal-shaped structure and is arranged in a ring array. One end of each base 73 is hinged to the lower end of the guide rod 74. The base 73 is provided with a first guide surface 731 and a second guide surface 732. The first guide surface 731 is located below the second guide surface 732, and the distance between the first guide surface 731 and the guide rod 74 is greater than the distance between the second guide surface 732 and the guide rod 74. The spring 78 is sleeved on the lower part of the guide rod 74, and its lower end abuts against the base 73. The guide sleeve 75 is sleeved on the guide rod 74. The top block 76 is located at the upper end of the guide sleeve 75, and the pressure block 77 is located at the lower end of the guide sleeve 75. Each support column... The 72 ring is set on the lower end face of the outer tube 71, and each support 72 is distributed between each base 73. The boring assembly 79 is respectively hinged to the support 72. By impacting the top block 76, the pressure block 77 is driven to move downward along the guide rod 74 to compress the spring 78, thereby causing the digging claw 791 on the boring assembly 79 to move outward along the radial direction of the outer tube 71, thereby boring out the stepped groove 6 at the lower part of the cylindrical pit 5. After the steel bar column 8 is embedded in the outer tube 71, by impacting the top block 76, the pressure block 77 is driven to compress the first steel bar 81 and the second steel bar 83 on the steel bar column 8. The lower ends of the first steel bar 81 and the second steel bar 83 respectively abut against the first guide surface 731 and the second guide surface 732, achieving bending and outward extension, which is highly convenient to use. After the steel bar column 8 is installed, by lifting the guide rod, each base 73 closes under the action of weight, thereby being pulled out from the middle of the steel bar column 8.

[0054] Furthermore, the boring assembly 79 includes a swing arm 792 hinged to the support column 72 at its upper end, a digging claw 791 fixed to the lower end of the swing arm 792, and a connecting rod 793 fixed to the middle of the swing arm 792. The angle between the central axis of the connecting rod 793 and the central axis of the swing arm 792 is 120°. During operation, the pressure block acts on the connecting rod 793, causing the lower end of the swing arm 792 to swing outward, thereby causing the digging claw 791 to act outward on the soil. Under the action of the spring 78, the pressure block 77 is lifted, causing the swing arm 792 to swing back. This reciprocating motion achieves the boring function.

[0055] refer to Figure 10As shown, the connecting assembly 12 includes a first connecting seat 121 fixed to the upper end of the anchor 10, a second connecting seat 122 fixed to the back of the template 11, an adjusting rod 123 rotatably mounted on the first connecting seat 121, and an adjusting sleeve 124 hinged at one end to the second connecting seat 122. The adjusting rod 123 has an external thread, and the adjusting sleeve 124 has an internal thread. Through the threaded connection between the adjusting rod 123 and the adjusting sleeve 124, the distance between the template 11 and the anchor 10 can be adjusted. Furthermore, through the hinge of the adjusting sleeve 124, the template 11 can swing, thereby adjusting the angle position of the template 11, improving the installation accuracy of the template 11, and thus improving the construction quality.

[0056] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
