Embodiment 1

[0033] Such as figure 1 and 2 As shown, a trench protection excavation support device includes a sheet pile I1, a baffle plate 2, a sheet pile II 3 and a bolt 4.

[0034] The sheet pile I is located on the left and right sides of the existing pipeline, and the sheet pile I is used for transitional support on the left and right sides of the existing pipeline, and is also used to connect and install baffles. Sheet pile I1 is connected outwardly with sheet pile II 3, and sheet pile II forms a grooved support structure, and sheet pile II 3 is arranged in a linear shape, and sheet pile I1 is connected with sheet pile II 3, and the distance between two adjacent sheet piles II 3 between connections.

[0035] There are baffles 2 and existing pipeline piercing openings between the sheet piles I1. The existing pipeline piercing openings are opening structures formed between the sheet piles I and the baffles. The existing pipeline piercing openings are used for crossing the existing pi...

Embodiment 2

[0042] The construction steps of the above-mentioned trench protection excavation support device are as follows:

[0043] Construction preparation: if image 3 As shown, carefully read the drawings, measure and stake out, mark the excavation line of the sheet pile, and according to the geophysical prospecting data, on-site mapping, and the disclosure of the pipeline property unit, the stakeout shows the direction and width of the pipeline.

[0044] Probe and find edge: if Figure 4 As shown, manual excavation is carried out to find out the actual boundary position of the existing pipeline.

[0045] Application of sheet piles: such as Figure 5 As shown in Fig. 1, sheet pile II shall be driven in the area affected by the existing pipeline, and sheet pile I shall be driven near the two ends of the existing pipeline.

[0046] Layered excavation: such as Figure 6 As shown, the area affected by the current pipeline is manually excavated, and the excavation depth of each layer ...

Abstract

The invention discloses a groove protection excavation supporting device and a construction method thereof. The device comprises sheet piles I on the left side and the right side, and a baffle and a current pipeline penetrating opening are arranged between the sheet piles I. The construction method comprises the following steps that construction preparation is carried out, wherein sheet pile excavation side lines are marked, and the current pipeline trend and width are set out; exploration excavation and edge finding are carried out, wherein the actual boundary position of a current pipeline is found out; sheet pile driving is carried out, wherein sheet piles II are driven in the manner of avoiding the current pipeline influence area, and the sheet piles I are driven in the manner of being close to the two ends of the current pipeline; groove excavation is carried out; and baffle installation is carried out, wherein the baffle is connected with the sheet piles I, and the baffle is attached to the groove wall. Compared with the prior art, the groove protection excavation supporting device and the construction method have the following beneficial effects that the problem that due to current pipeline influences, the part below the projection area of the current pipeline is difficult to support is solved, the safety risk of deep groove pipeline manual excavation is eliminated, the construction efficiency is improved, and the construction and management cost is saved.

Description

technical field [0001] The invention relates to a building construction support device, in particular to a trench protection excavation support device and a construction method thereof. Background technique [0002] A large part of water pollution control projects are located in municipal roads or community lanes. Due to the rapid development of cities and urban renewal, underground pipelines are intricate. The surrounding area of ​​the underground pipeline must be manually excavated, and the foundation pit under the projected area of ​​the current pipeline cannot adopt the normal support form. Especially for deeper trenches, manual excavation will inevitably produce greater potential safety hazards, which brings great inconvenience to the construction process. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and the purpose is to provide a trench protection excavation support ...
