Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.

Example (b): as shown in fig. 1-2, a basement drainage ditch structure, includes bottom plate concrete 1, the top of bottom plate concrete 1 is provided with terrace 2, drainage ditch 3 and angle steel groove 4 have been seted up on terrace 2, angle steel groove 4 is located the both sides at drainage ditch 3 top, reinforcing bar jack 5 has been seted up to the bottom of angle steel groove 4, the bottom of reinforcing bar jack 5 extends to in the bottom plate concrete 1, first reinforcing bar 6 has been inserted to reinforcing bar jack 5, the top fixedly connected with angle steel 7 of first reinforcing bar 6, angle steel 7 laminates in angle steel groove 4, angle steel 7 sets up along 3 length direction in drainage ditch 3, and fixedly connected with second reinforcing bar 8 between two angle steel 7, the both sides laminating of drainage ditch 1 has template 9, has placed the cast iron apron above two angle steel.

Preferably, the type of the angle steel 7 is L40 × 5, and the length of the angle steel 7 is 6m-9 m.

Preferably, the distance between the two opposite angle steels 7 is 38.5cm, the length of the second steel bar 8 is 39cm, and the distance between the second steel bars 8 is 1.5 m.

Preferably, the distance between the first reinforcing steel bars 6 is 1.5m, the types of the first reinforcing steel bars 6 and the second reinforcing steel bars 8 are both C12, and the length of the first reinforcing steel bars 6 is 12 cm.

Preferably, the depth of the bottom of the steel bar insertion hole 5 extending into the bottom plate concrete 1 is 6cm, and the steel bar insertion hole 5 is formed through an electric hammer drill.

Preferably, the angle steel 7 is welded with the first reinforcing steel bar 6 and the second reinforcing steel bar 8.

The following steps are installed in the implementation of the embodiment:

1. the angle steel 7 is welded with the first reinforcing steel bar 6 and the second reinforcing steel bar 8, and the operation safety is guaranteed.

2. Before the first reinforcing bar 6 of construction, will measure the elevation on 1 surface of bottom plate concrete, the elevation is measured and is accomplished the back, sets up reinforcing bar jack 5 with the hammer bit, and the first reinforcing bar 6 of accurate unloading inserts first reinforcing bar 6 in reinforcing bar jack 5, and the installation of first reinforcing bar 6 is accomplished the back, rechecks the elevation of first reinforcing bar 6 top once more, if there is the 6 upper end elevations of first reinforcing bar inaccurate, revises again.
