Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and in particular to a method for constructing a foundation structure of a seawall and sluice gate connection section. Background Art

[0002] An anti-scouring foundation needs to be set up on the riverbed at the connection between the seawall and the sluice gate to reduce soil erosion caused by water scouring in this section;

[0003] The existing foundation structures are all reinforced by filling with stones, but since there is no blocking structure above the stones, if the water flow is too fast and the stones are small, the water flow may drive the stones to hit the sluice body, affecting the service life of the sluice body. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-2 The present invention provides a technical solution: a method for constructing a foundation structure of a seawall and sluice connection section, comprising the following steps:

[0030] Step 1: Create grooves on the outer riverbed for placing blankets, upstream bottom protection, and anti-scouring troughs, and compact the soil in the grooves;

[0031] Step 2: Open four deep grooves in the groove and install the pile formwork in the deep grooves;

[0032] Step 3: Fill the deep trench in step 2 with concrete and insert the connecting steel pipe into the concrete. After the concrete in the deep trench solidifies, a fixed pile for fixing the upstream bottom protection is formed;

[0033] Step 4: Install the trough in the upstream bottom protection on top of the fixed piles by connecting the steel pipes, and fix the trough in the upstream bottom protection with connecting bolts;

[0034] Step 5: Install the blanket and anti-scouring trough plate on the left and right sides of the upstream bottom protection respectively, and use the plug posts under the two to match the lugs on both sides of the upstream bottom protection to connect the blanket, upstream bottom protection and anti-scouring trough plate into a whole;

[0035] Step 6: Insert the anchor rod under the anti-scouring groove plate into the groove in step 1 to fix the anti-scouring groove plate;

[0036] Step 7: Fill the trough in the upstream bottom protection with stones and cover the main retaining net on the outside of the stones;

[0037] Step 8: Lay a riprap layer on top of the anti-scouring trough plate and cover the riprap layer with a secondary retaining net;

[0038] Step 9: Insert the fixing nails into the main inclined groove on the upper wall of the anti-collision groove plate. The fixing nails are inserted into the secondary inclined groove under the guidance of the main inclined groove.

[0039] The invention also includes a foundation structure used in conjunction with the construction method, which includes a blanket 1, an upstream bottom protection 2, an anti-scouring groove plate 3 and a sluice body 4. The left side of the sluice body 4 is sequentially provided with a blanket 1, an upstream bottom protection 2 and an anti-scouring groove plate 3, and the right side of the sluice body 4 is also provided with a structure consistent with the left side, that is, the foundation structures on both sides of the sluice body 4 are consistent and symmetrically distributed. Because the structures on both sides of the sluice body 4 are relatively symmetrical, in the appendix of the present invention, Figure 1 Only the left side of the sluice main body 4 is shown. One side of the sluice main body 4 is connected to the sea, and the other side of the sluice main body 4 is connected to the pond.

[0040] Lugs 5 are installed on both sides of the upstream bottom protection 2, and plug posts 6 are installed on the side where the blanket 1 and the anti-scouring trough plate 3 are connected to the upstream bottom protection 2. The plug posts 6 are inserted into the lugs 5;

[0041] The blanket 1 and the anti-scouring trough plate 3 cooperate with the plug posts 6 and the lugs 5 so that the blanket 1, the anti-scouring trough plate 3 and the upstream bottom protection 2 form a whole, so that the foundation structure composed of the blanket 1, the upstream bottom protection 2 and the anti-scouring trough plate 3 is stable;

[0042] A main chute 7 is provided on the upper wall of the end of the anti-scouring trough plate 3 connected to the upstream bottom protection 2. A secondary chute 8 cooperating with the main chute 7 is provided on the side wall of the plug column 6 below the anti-scouring trough plate 3. One end of a fixing nail 9 is inserted into the main chute 7, and the other end of the fixing nail 9 is inserted into the secondary chute 8.

[0043] By providing the fixing nails 9, when the fixing nails 9 are inserted into the main chute 7 and the auxiliary chute 8, the plug posts 6 below the anti-scouring trough plate 3 cannot be pulled out from the lugs 5, thereby preventing the anti-scouring trough plate 3 from being separated from the upstream bottom protection 2.

[0044] The upstream bottom protection 2 includes a trough body 21, a partition 22, a main retaining net 23 and stones 24. The inner cavity of the trough body 21 is installed with the partition 22, and the trough body 21 is filled with stones 24. The side wall of the partition 22 is installed with the main retaining net 23, which is arranged above the stones 24. The main retaining net 23 can block the stones 24 in the trough body 21 to prevent the water flow from sweeping away the stones 24, thereby preventing the water flow from rolling up the stones 24 and hitting the sluice body 4, causing damage to the sluice body 4.

[0045] It also includes fixed piles 12, there are four fixed piles 12, the four fixed piles 12 are respectively arranged at the four corners of the lower end of the trough 21, and the four fixed piles 12 are installed in the external riverbed;

[0046] The fixed pile 12 includes a concrete pile body 121, a connecting steel pipe 122 and a connecting bolt 123. The connecting steel pipe 122 is installed at the center above the concrete pile body 121. The inner side wall of the connecting steel pipe 122 is provided with an internal thread. The upper end of the connecting steel pipe 122 passes through the lower wall of the trough body 21. The connecting bolt 123 is rotatably installed on the upper end of the connecting steel pipe 122.

[0047] The fixing piles 12 are used to fix the upstream bottom protection 2, and the two are connected together through the cooperation between the connecting bolts 123 and the connecting steel pipes 122. Because the fixing piles 12 are cast by concrete on the riverbed, they are more stable, making the foundation structure proposed by the present invention more stable.

[0048] Specifically, a riprap layer 10 is provided above the anti-scouring trough plate 3, and a secondary retaining net 11 is installed on the upper wall of the anti-scouring trough plate 3, and the secondary retaining net 11 covers the top of the riprap layer 10;

[0049] The function of the auxiliary retaining net 11 is the same as that of the main retaining net 23 , which is to prevent the water flow from sweeping away the small stones in the riprap layer 10 .

[0050] Specifically, a washer 13 is sleeved on the outer side of the connecting bolt 123 , and the washer 13 is in contact with the inner wall of the groove body 21 .

[0051] Specifically, an anchor rod 14 is installed below the anti-scour channel plate 3, and the anchor rod 14 is inserted into the external riverbed.
