However, this arrangement destroys the integrity of the lock chamber, is inconvenient to construct, and there are problems such as uneven settlement between the new and old lock chambers. Utility Model Content

[0004] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a new and old lock chamber connection structure, which ensures convenient construction and good integrity of the new and old lock chambers and avoids uneven settlement of the lock chambers.

[0010] As an optimal technical solution, a concrete anti-seepage blanket is provided upstream or downstream of the old lock chamber, and a new anti-seepage blanket connected with the existing anti-seepage blanket is provided upstream or downstream of the newly built lock chamber. The two anti-seepage blankets are flush with and connected to the bottom of their respective lock chambers.

[0011] As a preferred technical solution, a bottom protection is provided at the bottom of the partition pier, which extends outward from the bottom of the partition pier and is connected with two anti-seepage blankets.

[0012] As a preferred technical solution, the bottom protection and the top of the anti-seepage blanket are at the same elevation.

[0013] As a preferred technical solution, an existing energy stilling pool structure is provided downstream of the old lock chamber, and a new energy stilling pool with the same structure as the existing energy stilling pool is provided downstream of the new lock chamber; the downstream bottom protection is provided with a slope section with the same slope as the two energy stilling pools, and the slope section is located on the left and right sides of the downstream partition pier.

Due to the limitation of the width of the river channel, this embodiment is described by taking a newly built lock chamber and an old lock chamber as an example.

[0029] Side piers 3 of equal length are provided on the adjacent sides of the new and old lock chambers along the water flow direction, and the area between the side piers 3 is backfilled with a crushed stone cushion layer 4 of a certain thickness and compacted manually.

[0030] Adjacent side piers 3 are connected as one under the gravel cushion layer 4, and the connection is reinforced by roughening and placing a plurality of embedded steel bars 13. Preferably, the width of the side piers and the gravel cushion layer is 1m.

[0031] Preferably, the bottom layer of the crushed stone cushion layer 4 is wrapped with a 5 mm thick geomembrane 5 to prevent water seepage, and KS glue is applied to the side of the geomembrane 5 that contacts the upper surface of the side pier 3 for bonding. A first water stop strip 9-1 is provided at the bottom of the crushed stone cushion layer 4.

[0034] In practice, a concrete anti-seepage blanket is usually provided upstream or downstream of the old lock chamber 1. In order to enhance the integrity of the connection between the new and old lock chambers, a new anti-seepage blanket 8-2 connected with the existing anti-seepage blanket 8-1 is provided upstream or downstream of the newly built lock chamber 2. The two anti-seepage blankets are flush with and connected to the bottom of their respective lock chambers, and a third waterstop 9-3 is provided at the connection; a square reinforced concrete bottom guard 7 is integrally formed at the bottom of the partition pier 6, and the bottom guard 7 extends outward from the bottom of the partition pier 6 and is connected to the two anti-seepage blankets, and a fourth waterstop 9-4 is provided at the connection; preferably, the bottom guard 7 and the top of the two anti-seepage blankets have the same elevation, and the two are connected in a plane, which is more convenient for construction.
